This video goes through how to use INPA to diagnose engine problems on the 6-Series, and in particular the N62 V8 engine, but these routines are suitable for all BMW engines right from the 3 cylinder to the V12. It's great fun, and you can't do much harm. In particular I go through Adaptations - and the dreaded error adaptations at limits.
We spend a bit of time explaining Adaptations and what the values mean. The strange terms such as Lambda Integrator, Total Air Consumption HLM, and the difference between Additive and Multiplicative Adaptations - all explained here.
OBDII to 19-pin adaptor: amzn.to/33CFRWN
INPA: amzn.to/33D2NoT
Further information can be found here: www.meeknet.co....
Diagnostics can seem daunting to start with, so many pages of information and things to fiddle with. Most of us just check the error codes and leave it at that. Fortunately, there are three pages on INPA that gives us a window into the engine that is easy to understand.
Although this routine shows diagnostics on the M62 V8 engine, the INPA pages used here are useful for all BMW engines. These three pages, Analog 1, 2 and Smoothness gives an insight into the condition of the engine and any impending problems.
We also look at Adaptations and how the values can enable us to get the best performance and engine economy.

This was the best video explaining INPA, with extensive context for every function covered, pure gold. Most clips on yt are sub-par made my people who don't know what they are doing or are unable to explain properly. A series covering other aspects of BMW software coding/programming with this level of detail would be brilliant
Very kind of you! I have two other videos on INPA on my channel
Easily my favorite content creator on CZcams. Every time I think about something to do with my car it seems Tim will put out a related video within a couple of weeks. I'd love to know the total amount of money you have saved people on repairs with your videos. That's something to hang your hat on👍🏻
I don't have a hat - but that's very kind of you!
Thank you Tim, I finally have INPA working on my E46 and your explanation's Sir, are first class, thank you for taking the time and effort to assist us all, cheers John in Australia.
Glad to help John!
I just found you channel and can't stop watching and reading. There are not many people explaining that well
I am trying to fix a problem on my 26-year-old E39 (I am driving 20 years), which none of the last 4 car workshops is able to fix. Many thanks for your absolute brilliant explanation an INPA! Great job! Michael from Germany.
Always my pleasure!
The most informative understandable explanation and most of all informative video I’ve ever watched on CZcams outstanding well spoken well explained need I go on if you want to learn about I in PA watch this video there is not another one that even compares to it this guy explains it in a way that is so simple and straightforward and understandable everyone should take notice and follow this guys lead outstanding thank you very much for the info
That's very kind of you Anthony!
Would really love a follow up on the gearbox! This video is great - I’ve always wondered what these numbers mean up to this point. Thanks.
Done it already - it's up on Friday!
Good job, all said right, I have the same engine, it has a high additive values +2-3; then I found a vacuum leak, fixed it, the values went back to +-0. Engine run smoother now.
Good luck ! Welcome from Belarus
Nice work Pavel!
Just bought a 650i and already this guys videos have helped me fix a few problems. Thanks to the creator, he’s obviously very knowledgeable with regards to these cars/engines.
Great to hear!
What a brilliant explanation, thanks for doing this! I’ve just bought my 3rd E46 (the 2nd was 21 years ago 😂) and your videos are invaluable.
Glad I could help!
Very good explanation I have a BMW E46 and I use INPA. Greetings from Aruba
My pleasure Fred from the UK!
Perfect Video. As it turns out, I recently ran INPA on my 2008 650i, N62, and printed the results. I was able to follow along with your video, and interpret the results (German to English) , and understand the data. My engine looks good. Looking forward to your future INPA work.
Great to hear!
From a Limey living in LA, your videos are a breath of fresh air, particularly as I am 2007 650i N62 owner! Can I suggest you make a video of a tour around the engine, showing each component and giving your explanation on function and possible issues. Your channel has inspired me to work on the car and fix things myself, but I am definitely no mechanic (I usually fix people). Thanks for considering this and keep making these great videos.
Now for a nice cup of tea...
Sounds like you might be a medical doctor. Just think of your car as another patient, but protect your hands! Lol
Hello David, good to hear from you - now, about my knee....only joking! Yes, a tour around the engine bay would be a great idea - I'll do that!
Extremely helpful video.
Glad it was helpful!
Timm's you are the best in diagnosing bmw with inpa, i learn so much from you of understanding Inpa, Thank You, If you ever get a chance i hope you make a video on how to raise idle speed rpms using Inpa, a lot of us raelly need to know about that, we know about going to activate in inpa to raise idle speed rpms but the Question come will the rpms stick in the dme once turning off vehicle and restarted, so basically we trying to get the rpms to stick in dme after raising them with inpa, love your videos and keep up the good works thank you again
Will do!
Thanks. So we’ll done and explained. Top class
Thanks, it was fun making it!
Thanks Timm. Your explanations are really clear and informative. I have learned a lot, and appreciate you sharing the inofrmation.
Glad it was helpful Diana!
Hi Timm this is Alvin. I have the 2005 645ci with 50,000 miles. ( I have no problems with my car) Thank God.
What Preventive maintenance repairs should I be looking into.
From your biggest fan. Thanks for another GREAT video.
People bash this generation of bimmers...I own 2 745li...both silver and I love em...as long as make sure the cooling system is working right and change the tranny fluid..oil change..it’ll run forever...I gained so much knowledge about the n62 6 months ago I went and bought another..lol...now I’m looking for a 645ci like yours.

Thank you for all your help.
Blessings to you and your family. Do you have any YouTub channel for repairs?
@@alvintobe5566 I don’t have a channel just yet...but possibly in the near future though..and thanks.😎
Hello Alvin - all explained here: czcams.com/video/Uzc9vQGuNnk/video.html
Good work Tim love to watch your vids. Really helps me with my z4 e89 3.0. Cheers, Steve.
Glad to help Steve!
A very good explication, thank you!
You are welcome!
Tim you and your channel are fantastic. Are you/were you a BMW Master-tech? Had BMW’s for the last 15 years so somewhat seasoned in repairs and fault diagnosis, but your knowledge is incredible. Shame you don’t do a subscription health check service as a side line. I’d definitely pay for that 👍
Thanks Dizzy, very kind of you!
Hi Tim, In my N62B48 both Additive adaptation on bank1 and bank2 values are positive (about +1 sometimes lower) Is it correct ? Multipilcative adaptation values are also 0,94-0,97. My problem: When car is at a standstill and I press the gas pedal hard on a hot engine, can be heard for a moment sound like (subaru) in muffler - some missfires I think.. but if I press the gas more slowly, everything is OK. Everything is also OK when I turn off valvetronic, e.g. by disconnecting the exhaust camshaft sensor. On the cylinder head bank 2 I replaced the intermediate rocker arms with new ones and 8 HVA regulators (I had a constant error: cylinder 7 misfire). There is currently no error in DME. Thank you for your suggestion
I hope it helps, you've done the heavy work already!
Very good Instruction and explanations, Luckily I learned German also. I will be checking more of your content.
Thanks Richie!
Thanks for this very clear and very informative video
Glad it was helpful Carl!
Great video Tim, wish I'd have had it last year when I was fixing up my 7series 745i (N62). It hadnt run since 2014 so 6 years in a garage with no servicing. It was missfiring on 4 of 8 cylinders. Eventually after playing with various odb readers I was able to figure out the MAF was very dead reading a value of 599 constantly. That got me closer, then their was a couple of huge vacuum leaks in a few pipes, the vacuum stabiliser things on top of the heads had huge holes in them too. I also had a few dead coils and decided to replace all of those and the sparks. Lots of oil around the sparks so a rocker cover gasket swap is on the cards for future. Ever done one? I hear vanos can be a pain to remove. I also had a dead valve that recirculates the gasses from the fuel tank, that one took ages to figure out and was putting the light on the dash which was really frustrating and only figured it out once I got to grips with inpa although I've never managed to get it to read errors in English. Once I had the engine running it was the turn of the other errors and mostly the airbags, although I was able to reset them.
Great work Steve!
I had a similar experience getting a 4.8is running after sitting for 1 year. It had a dead fuel injector, 4 bad coils, bad MAF and bad purge valve. Now it runs without any error codes. amazing!
Sorry to bring up an old video, I was watching trying to diagnose an intemittent 02 sensor code. It randomly, becoming more common infact pretty much when it warms up it starts to misfire and throws a 2C45 code. The code is for pre cat 02 sensor, I will replace it, but i was watching some live Inpa diagnostics and my air mass was varying from about 12 to 20 kg/h constantly. Is it worth replacing the MAF sensor as well ? or should i just give the wiring a going over
O2 sensor warnings are an indication that the fuel/air mixture is wrong - not the sensor itself. If the MAF is showing a huge range of readings then yes, it should be replaced - OEM BMW only!
Paint shop left my car on too long and killed the battery. I believe my EWS is out of sync and am having codes for starter relay and intermittent transmitter. I’m trying to connect to my EWS module to reset it but for some reason will not connect. I have the K+DCAN cable with a switch on it and it won’t connect for whatever reason. I go to the EWS section and it automatically says it can’t read. 2002 E39 M5. Do you have a website you use to read the lengthy codes?
I don't think it is the EWS that you have to communicate with - it's the DME - can you connect to the DME?
I'm trying to get into INPA. It's really the only option if you're on some of the old Bosch Motronic 3.1 stuff. Like the early M50's and M60's without VANOS etc. Those ODB cables are no good for the old engines. You need a connector for the 20 pin plug in the engine bay, with serial plug in the other end. Then you need a laptop with an actual serial port and bloody windows xp. Serial ports stopped being on regular laptops around 2007.
The only ADS interface still around is the Tiny ADS, but it does work!
This was the first video that explained so much about INPA and what everything exactly means. Thank you very much for the easy explanatory. My N46B20 runs a bit rough sometimes. I replaced the MAF but INPA shows a Air Mass of 8.5 in idle. Is this normal? Because it should be around 22 and 25 right? Could something else be the problem besides the MAF
Thanks! Yes 8.5 is much too low, check for a hole in the bellows between the MAF and the throttle body - if all good then it's time for a new MAF
That was very informative. I like INPA and have found it useful over the years, its good for people who want to really understand what is going on. I have tried various breeds of Modic/Dis/ISDA over the years and found them more confusing than the problem I am trying to fix... I purchased the interface in your link because I get processing errors with my old one.
Yes, INPA is the best for fiddling as long as you understand the readings - and that is what this series of video's hope to achieve!
Nice one Timm. Well sorted machine!
Thanks Jason!
question.
why don't I have the SYSTEM DIAGNOSTIC option?
i'm need to revalue my new injectors
Unless you have replaced the injectors with the wrong type there is no need to relearn anything - the engine does this constantly
Hi Timm
Always fascinated by your video!
Can you please tell me where I can download the program fro my BMW E31 m62 engine?
Thanks Maestro 🙏🏻
Hello Adriano, INPA can be bought from Amazon or Ebay along with the lead - see description
@@TimmsBMWRepairsandInformation u r the Top Man
Thank you so much Timm, your knowledge has saved thousands of us, a lot of time, and $$$. If you wouldn't mind; I have been chasing an answer to a camshaft adaption ghost in my N62. Bank 1 values are perfect, 67.80 / 126.20 respectively Both in the green! Yet, Bank 2 Output starts in the green (68.00, though adaptation input bank 2 is well low @ 67.90. So (B1 67.80 output = green / 126.20 input = green), and (B2 Output 68.00 = green / 67.90 input = red). Have you a suggestion why? All the CPS have been changed or new, solenoids are new. INPA fault codes 2A89, 2A84, sometimes also 2A91.
Hello Troy, start with changing the chain tensioner on Bank 2 - it is the easiest of the two and is accessed in the 'V' of the engine.
@@TimmsBMWRepairsandInformation Thank you Timm, chain tensioners have both been replaced, valve stem seals, oil pressure switch, and pcv valves. Could it be a suspect VVT motor?
Hi tim i have inpa but i cant read live engine data. İ cant conect the wngine module wich versions inpa do you use?
I'm using UK v3.1 Version 5 - but as long as INPA lists the E63/E64 it should read live data
@@TimmsBMWRepairsandInformation thanks timm
Hi Timm, I'm somewhat confused here. I was about to get ISTA, and now watching your video should I get INPA?? Are they the same? Sorry I'm fairly new in the BMW world
No, not the same, I only use INPA
Hi Timm! I assume you have English INPA for your E63 N62 as well. Would you mind sharing your EC-APPS/INPA/SGDAT files? The only files I have managed to find are all in German... I have lost so many hours trying to find English versions but with no success. I would be extremely grateful for your help. Thanks for all your knowledge!
Edit: I have English menu but the submenus and subtitles (above the charts/bars) are in German.
It is a mystery to me why my INPA suddenly goes German - sometimes it's fine on the E31 and German on the E64 - sometimes the other way around!
@@TimmsBMWRepairsandInformation Thanks Timm, appreciate your response. Seems like it's time to learn German!
Any idea if INPA can do DME CAS alignment/sync on BMW E66?
Sorry, I haven't tried, but CAS is available on INPA so I don't see why not
Nice and clear. Well done.
Thanks!
Fantastic video buddy and really glad to have found your meeknet webpage. I really enjoy the detailed sort of "old school engineer" way of talking about things. Really brilliant. Just started trying to diagnose (and hopefully fix) an N47 engine and just discovering this INPA thing which was a bit intimidating. Feel less intimidated now - Thanks :)
Thanks!
Alucinante sus conocimientos!!. Muchas gracias por compartirlos.
Gracias Fran, ¡me alegro de que lo hayas disfrutado!
Thanks very interesting, could you tell me if inpa works on E84 as I cant seem to get it working and want to know if I'm wasting my time trying .Thank you
Bmw pro sir Tim I am having a 27bb dtc on my 2004 e46 n42 I can't seems to find a good solution to it anywhere could u help me with it plz
Anybody found a way to check the oil level using INPA?
Great insight and information 💫
Glad it was helpful!
Where do you get the INPA software.
All explained here: czcams.com/video/6LWXmz6Ef_M/video.html
Excellent information. Thanks
Glad it was helpful!
Hi timm, love your videos i wanted to ask you if you have had your engine idle speed set point adjusted, it's 750 in this video, mine is at 550, idles better a bit higher, read in forums that 550 is normal for N62 and 700 with ac on.
No change made, but with working air conditioning ON the revs should rise to around 700. This has been the case on all BMW'S since A/C was introduced
Hi could you pls assist with a reading of my m6 smoothness level. Pls advise on how I could have the media sent through to you. Thank you
Always the best way to sort these problems is to post them on the 6-series forums on Bimmerforums.co.uk - you will get better answers!
How can I set the I/M status to completed for the secondary air system monitor?
Vanos ?
Hi Timm. Thanks for the great work with the videos. I am considering purchasing a 645 2004 coupe at a heavily discounted price. The car has not been driven properly for almost a year and seems also to not have been that well maintained. Went in for oil leak fixes just before being parked. Also has coolant lights on etc. Is it worth the gamble?
Impossible to say without seeing it!
Good video mate!
Thanks!
Can you please provide me the INPA software that you have? Thanks
Have you run into incredibly loose ignition coils? My n62 4.4 has some bosch and some NGKcoils. Some coils are nice and tight while others just seem to be staying in place just by the bottom portion that joins the sparkplug. It doesn't matter how hard I push, some need no effort to pull out. Could it be the spark plugs tubes not sealing?
Yes, but on the M62 - the loose HT boots are caused by oil contamination on those. They should be tight - I only use Delphi coils and have never had any problems with them.
timm does inpa work on bmw 1998 E39 525 TDS with the M51 motor LHD french car
Yes, it should do, it works on my E31 of the same year - however, check with the seller
Tim, I have German inpa. How do I get English version of inpa? TIA
Go onto the Bimmerforums.com diagnostic forum and they will tell you - however, even following the advice on there mine sometimes turns to German!
I have a issue with my E64 2008 650i ,
That once I hit start engine it doesn’t start , then by several tries it works I wonder why although I have no faults and errors what to do ?
I know this is 4 months ago and you probably figured it out but did you check the engine ground cable? seems to cause a lot of issues for people with our cars and is super cheap to fix. They are always super corroded.
Hi Tim, Great vid, very informative. Just to say I made a comment in your other INPA video about my slightly rough idle and I think my values on the page 'analog value 3' the O2-sensor Add Banks 1 & 2 are -1.70 and -2.30 which suggests a lean adaptation ? , unlike yours which are much closer to -0.3 & -0.5.
Q. Do you think I'm looking at a MAF fault as I don't think it can be an air leak?, Thanks for your advice. J
It could possibly be MAF - but your values show the mixture is too rich by a small amount - and that could be misfires - possibly causing the rough idle.
Thanks for the reply, OK yes. Couple of things before all of this, I did get the coil packs changed and the four vanos. So before I even get to look at the injectors, I think your suggestion of investigating the MAF is a more plausible option. Do you think cleaning the MAF is a good idea. Or a replacement is probably better?
Thanks for all your help and videos. Best. J
Hi Tim! Great video, I have an E87 116i with the N43 engine. I have an intermittent long crank after car has been left for 30 mins to an hour after running, the car smells badly of fuel and has poor MPG. Coils, plugs and injectors have been replaced but Cylinder 2 smoothness shows variations between -2000 to 3000. High pressure fuel sensor also shows -444.000 do you have any ideas what could be wrong? Thanks in advance
Hello Dan, the fuel pressure has to remain high even when the engine is switched off - for many days. From your description it sounds as if the fuel pressure is leaking away which is why you can smell fuel. Pop the covers off and have a look around the fuel pipes.
@@TimmsBMWRepairsandInformation Thanks for the reply Tim really appreciated! I have checked for leaks with no avail. I think the previous owner did not do the injectors as stated as it is blowing a lot of white smoke/vapour when first started and you can hear slight pops in the exhaust
Hi, this was useful. I used on my 650 which will not start. I have just replaced the valve cover gaskets and suspected a bad connection on camshaft sensors, but all was good. Worrying thing is that whilst using INPA the ignition coils started to smoke. I removed one and it feel apart. Any ideas what could be wrong?
It sounds as if the coil return loom has been trapped - check your work again!
@@TimmsBMWRepairsandInformation thanks Timm, what do you mean coil return loom trapped? I am desperate to sort this. Whilst replacing the valve cover gaskets I had the control box cover off. Overnight though the bonnet was down, water got in. I took out the VVT and DME and dried them out hoping they would be OK. That is when I had the melting coils. Someone told me I have a damaged IVM, so replaced that. Also replaced all the coils. Cleared all the error codes. Tried cranking and now my new coils are melting. It appears to be the same 3 as before. I believe each coil has a 12V +, neg and a trigger signal. If I have a trapped loom does this mean something is shorting to ground? Your help would be appreciated. I am on a couple of Facebook forums and no one can help. With the background detailed, could this be a damaged VVT or DME? All the best, Mick
Great vid, thx!
Thanks Yuha!
Gutted my 635d is a write off after water damage from flooding the other day need to buy another just don’t know which one thinking 645 or 650 they all seem quite high mileage 100000 plus which is little bit scary for a v8
Get a 650i - More horsepower is always the winner!
Great video!
Glad you enjoyed it
Timm, you have absolutely the best videos for all things E64. I have a 2007 E64 and I just replaced the battery. Does INPA allow you to register and code a battery? Should I load INPA on a computer that I use for nothing else?
No need for a separate laptop - I've got all sorts on mine! If you are replacing the battery with an identical one there is no need to register
@@TimmsBMWRepairsandInformation I know it is now 9 months but in case you read it, if tha battery replaced is the same capacity it does not need to be coded but it needs to be registered for the charging system to adjust charging voltage.
Could you identify bad compression or head gasket problems with INPA? ('97 M62)
You would get high roughness values - but a compression test is the way to go Onkel!
All adaptions in my car are reading 0 all the time even if I cause a vacuum leak. what could be the issue
If the adaptations stay at zero then the Lambda sensors are either not up to temperature (takes around 5 minutes) or are not connected or have failed
Agreed, I used INPA on my E39 with 76K miles and seen the values off the chart and found that the boot going into the TB had a rip a the Y, autozone $21 and all back to normal now. Tim for those of in the USA what is "tick over"??
“Tick over” == idle rpm
Lol. It takes a while to get used to their slang but I bet they have as much trouble with ours.
Thanks John, yes, I must use 'idle' as tick-over does confuse!
Thank you...^^
My Pleasure!
Good info indeed! THX
Glad it was helpful!

Hi Timm
Do you have any experience with car not starring first crank but perfect on the second attempt when engine is hot ?

Have trplaced all relevant sensors relays and fuses including mafs fuel filter and regulator fiel pump .......
Only thing that is still original are the coils and starter motor. Vehicle has 150k km
Any help would be appreciated.
Joe
Yes, that is most likely loss of fuel pressure when the engine is off. It should maintain a pressure of around 2,5 Bar indefinitely. The pressure is maintained between the Fuel Pressure Regulator and the fuel pump which has a one-way valve built into it. Some owners fit a one-way valve in the fuel line because of the cost of pump replacement.
@@TimmsBMWRepairsandInformation
Thanks Timm
I will check that out.....I have already replaced the fuel pump, fuel filter and fuel pressure regulator with genuine BMW parts ??
The sensors always seem to be the weak point.
Hi Timm, I notice you get around 22 kg/hr on your MAF at idle. My X5 4.8is with N62 motor is getting about 29 kg/hr at idle, and INPA is saying that is out of range. That's with the AC running. I should try again without the AC running, but does that sound high to you?
29Kg/hr isn't too bad, it will drop if the A/C is switched off
@@TimmsBMWRepairsandInformation Thank you for your feedback! Turned off the A/C and checked the engine via INPA today. It was 18 kg/hr at 700 rpm idle when warmed up today. X5 had been sitting for a year, but finally have it running perfectly without any error codes!
Hey Tim, great explanation is this similar for the e36 or the e39 series?
Thanks, and yes, common to all BMW engines post 1999....
@@TimmsBMWRepairsandInformation thank you for this Tim! The community will be very grateful if you make a video about the n62 engine and bmw 6 series things to watch out for if you're buying second hand!
Hey ,have you ever come across dtc 4e87 on e60? Couldn't find much info about this code?this car in limp mode altime
That is a solenoid problem - and always the way to tackle this is: 1) Buy a new battery - failing batteries cause solenoid problems! 2) If that doesn't help then change the fluid and filter
@@TimmsBMWRepairsandInformation isn't solenoid on the shifter assembly?
Does this work on a 2014 535d xdrive f10
Never had a diesel but I would guess it will be similar!
Why do you have 4 power windows? Because you have a convertible?
Yes, I was really surprised that the E63 didn't having dropping back windows - or was pillarless whereas the E31 has both. The E64 convertible is the same.
can i clear the engine adaptations with inpa?
Yes you can!

Hi Timm. Do you ever use ISTA D/ ISTA+ and what do you think about it?
Hello my friend! ISTA and DIS just run so slowly on my old PC I just can't use them - and I find that INPA does all that I need to - and very little chance of breaking anything!
@@TimmsBMWRepairsandInformation I like inpa but inpa doesn't have some of the features that ISTA+ has. I have a facelift E38 with a very rare Active cruise control that nobody can fix for many years. I started learning how to use ista+ and eventually I managed to re-calibrate the ACC unit. As far as I am aware you simply can't do something like that with inpa. Great video and very informative as usual.
Hi Timm, trying to track down an intermittent rough idle on my e63 n52 engine, could you help me figure out what's happening? I've uploaded adaptations video, cheers. czcams.com/video/0x2hXJvHQTo/video.html
The adaptations look OK, possibly affected by a misfire - so it is not a fuel/air problem, more likely plugs and coils.
Timm's BMW Repairs and Information, Wow! Thanks for having a look 😊! I have done the usual suspects - coils, plugs and injectors. I’ll check out vanos solenoids and MAF then. Cheers 🍻
