Thank you
Hi
This car came to me nearly 1 year ago...
Came running very poorly, no power at all, no acceleration, and smoking really a lot!
The car was supposed to come back to do other stuff, so I kept the clips to then carry on recording...
But the car never came back, and I have a feeling that it has been scrapped...
Here, I leave you with the diagnosis of what was causing the problem...
Which is a bit common on these engines...
Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching! - Auta a dopravní prostředky
Good job Luis like always. More success friend and thanks for all your videos.
😊
Thanks!
👍👍👍
Nice diagnose Luis . I think this damage happened because of a run away engine . Most logical for me .
Possibly...
🤷♂️
Thank you for watching and for your comment!
👍👍
I had a 2004 A3 2.0 TDI and other than the common hot starting issue i had no trouble with it all. I did maintain it well and was the infamous BKD engine.
👍👍👍
Good video 👍
😊
Thanks!
👍👍👍
My worst car ever had this engine I was constantly spending money repairing it such a bad design , Top work mate 👍

Only if you don't look after them snd change oil 4 times a year and do oil pump conversion to a 1.9 tdi otherwise they're brilliant and bulletproof. Best model they ever built the 1.9+2.0 tdi. Just fools run them into the ground.
@@shaneryaner mate how do u do conversion
Got 260k on mine..great cars.@@shaneryaner
If it was just one roller that came out you might think it was an "accident", but the fact that there's at least 2 of them points to something else. I suppose the obvious conclusion would be a timing belt that jumped a few teeth, or an oil/pump problem.
If it was an incorrectly fitted timing belt then it would likely have been spotted soon afterwards and taken back to the person who fitted it.

Bom trabalho doutor luis...e muito bom dia.abraco

Obrigado!

Hi,
In VW UIS unit injector system they have problems of camshaft, is a very common problem.
😊
👍👍👍
👏👏👏

👍👍👍
There’s a lot going on under the cam cover on those PD twin cam engines
Indeed!
👍👍👍
Top!
😊
Thanks!
👍👍👍
Luís, could this car had an over rev situation? Is there an OBD code for that? Is it possible to use the MaxiSys to check this situation from the past? Are over rev situations recorded in the ECU?
Not sure if this ecu supports freeze frame...
Maxisys can indeed access the freeze frame data, if supported by the ecu...

I am having the same problem with my A6 2007 2 litre TDI with BRE engine. I am hoping it is not any lose roller in the engine. I have had the turbo fixed and lots of other new parts on the intake system fitted (myself). Funny thing with mine is that a few weeks ago it was working ok when i put the repaired turbo on, black smoke had gone and it was running fine, revved to 4000 RPM plus, but then a week atferwards the black smoke returned and wouldnt go passed 2000 RPM. I am thinking its the PCV valve at fault.😪
Look for turbo leaks also
Hi, have you fixed the problem?
@@johnmarck5986hi. Yes I have. The turbo had blown but also the dpf was completely blocked so it got a new aftermarket one fitted and runs perfect now
@@b4tm4nrubin33 thank you, my dpf filter it's empty already
Thank you very much
Aout the wiper of w220 benz i have the same problem that youvexplained befor (relays flashes) i jumped the same wire then it works good. So can i keep it jumped ?
Its not easy to do fix the key fob
Thank you
I would fix the problem... rather than leve it bodged...
Thank you for watching!
👍👍👍
@@LMAutoRepairs
So is there a problem if it stay jumped ?
Until i replace the key fob
Thank you for answer 🥰
Possibly no...
Leave it at your own risk...
👍👍👍
ow someone fitted cambelt wrong and snapped the rockers , done a few of them :)
😊
👍👍👍
Top diagnostics Luis. When I read 2.0 TDI in the description and heard you say 2007, I immediately thought of oil starvation - a very common problem on these due to the oil pump suddenly stopping working, caused by a snapped hexagon shaft driving it from the crankshaft. Could oil starvation have killed the tappets and destroyed the valves?
Possibly...
👍👍👍
I had the exact same problem from a 2009 2.0 TDI (170 Cv). The oil pump failed due to that silly hollow hexagon design and, almost instantaneously, the turbo. The problem is that the car information system gives a misleading warning message to the driver and you carry on driving after a simple and inconclusive oil level check.
@@pedroneves8288 Absolutely, it is just ridiculous all this malady is all down to a twopence hexagon shaft and a sixpence software code line.
@@matejanosvarga4478 Quite right! Unfortunately for me it was all down to over 3000€ repair!!! Audis, VWs... Never more, even if electric!
Jeez that is painful..... They would simply have to continue making cars like the Mk4 Golf but, unfortunately, reliability does not seem profitable
Does anyone have an idea what this could be?
Ive a6 c6 2.0tdi, 175bhp version.
When started first thing (cold engine) it works absolutely fine, sounds fine.
Once it starts getting close to working temp, and on working temp, sounds rattly and is interminently shaky on idle.
Whilst driving, car pulls completely fine, no smoke, nothing else wrong with it.
Im dealing with pd170, same symptoms. Checked and adjusted my cam torsion (intake and exhaust cams) intake being at 0.0 and exhaust side you measure consumption on idle/warm.. should be at 0.4l/h to 0.6l/h. My injector 2 is firing 1.5mg fuel compared to others at -0.3mg. In my case I will be changing seals on injectors.. cleaning the nozzles and finally adjusting rocker arm nuts on top of injectors. At last readjust cam timing and chsnge cambelt.
I recommend vcds or obdeleven obd reader to check the cam torsion - page 04, fuel injectors are on page 13 and consumption is on 15.
Let me know if this helps and if you solve it.. I'm interested what it could be on yours
Also could be egr or dpf if you still have them turned on.. I'd start with diagnosing those.
As a little update, I did 5 runs with intake torsion adjustments.. turns out +1.09 torsion is best for my engine.. at 37mpg.
I have set back the fuel pump cam back bit by bit and at one point heard slight knocking.. I am assuming rocker arm nuts need an adjustment or like stated before a dripping injector which I will look into when I receive the seals.
Hi did you fix problem
Hi Luis, where in the uk are you based ? I’m having major issues with a crash sensor on an 02 vw bora !
Hi,if I will have this problem what's the solution to fix it?
Well, quite self explanatory... camshafts out etc...
👍👍👍
Looks like she broke the cam belt and someone decide to: "put new one and see what happens". And this what happened.....
Possibly...
😊
👍👍👍
Can you link the video when it comes back from being 'fixed'?
Never came back... was probably scrapped...🤣
This 2.0 PD engines is not worth repairing anyway. They also tend to snap camshafts and oil pumps on these are very bad design.
😊
👍👍👍
well done, big money repair probably. shame
I would guess the same...
😊
👍👍👍
Now that you removed that.......the engine should run better.....
😅😅😅😅
True!😋
Brother I desperately need your help on a peugeot 307, it won't start please can we have a form of communication please
Hi
Have you scanned the car?
What is the background of the car?
👍👍👍
@@LMAutoRepairs did scan the car, it had a engine and transmission replacement and I changed the modules under the passenger dash, Underwood, and the key chip to the ones from the car I got the engine from
What about the engine ecu?
A replacement engine, does not requires modules to be changed...
@@LMAutoRepairs changed the ECU , scanned the car and it says ECU unlocked
If possible could we video call on WhatsApp if you use the app? Maybe we'll manage to explain everything much easier
The belt must have snapped
Possibly...🤷♂️
👍👍👍
very expensive fix i would scrap it
I believe that is what was done anyway...😋
👍👍👍
But where those rollers are coming from, exactly? Where they belong, what is their job? I don't know this engine sorry.
From the rocker arms bearings... they are the internal bearing shaft...
Thank you for watching!
👍👍👍
Why are these Audi's always broken when people buy them cheap and don't maintain them
😊
👍👍👍
@@LMAutoRepairs Are those PD engines any good like VW people claim they are
@@neilmurphy845 yes they are good engines some people dont know how they work or how to look after them
