I have a 2002 VW Eurovan Weekender. I’ll be watching all your videos! THANK YOU!
Thank you!
Your a German Guru. Great to follow a knowledgeable tech.
LOL... I'm just pointing at stuff and giving it a name. Did you see Tom's new video about the passenger window on a Beetle. That was good stuff!
czcams.com/video/lLTKYxBESP0/video.html
You covered this engine very well! Looks like it has a few oil leaks. 😀👍
Never fix everything during 1 service... always leave enough work for another day! =)
Thank you so much! I have a 1995 Rialta, which may likely be a 1994 Eurovan, with automatic transmission; I'm looking for the transmission control unit. It's in limp mode and this is one of the connections I was told to check. Thanks again!
Early version vehicles have the TCM under the glove box, behind the carpet that's against the right side of the body.
If it's not there, check on the driver side.
If owners of this car find this video they will be very happy for the information. As for me, I just like hanging out in the shop to see what your doing. :)
Thank you!
Good bits !
Thank you!
Thank you so much! very helpful....
Thank you for watching!
I'm guessing you've worked on a few of these. Great info
Some.
Hahah, Thomas in action ... do youever rest? No, your like me... believe me or not, I saw more flamingoes yesterday... :-)
=)
I’ve got a 1995 2.5 aaf with the two pin white and black connectors. I just keep getting no coms. Any advice is most appreciated.
Keep up the good knowledgeable work.

You’ve helped me soooo much with your videos. I’m tackling motor mounts, are those pretty easy?
The easy one is the rear diff mount... the other two require the engine / transmission to be lowered slightly, so that the mounts can be removed. Can be a bit scary, considering the weight of the vehicle (raise on to jack stands) and then having to support / lower the engine / transmission. Work safe!
Thanks for your series of great videos! What's your preferred procedure to access and replace the exhaust manifold on 93 AAF?
Remove the intake manifold, disconnect the downpipe from the exhaust manifold and then remove the exhaust manifold.
They did away with a trans dip stick way back then! Huh, I thought that was a new thing. Electric water pump too. Thanks!
"Vorsprung durch technik!" Oh, wait... that's Audi! LOL
hi only just got a t4 petrol 2.5 manual
but has alot of neglect issues.
TOP MARKS ON YOUR VIDS VERY INFORMATIVE
but working through them.
but doing crank seal at the mo.
but the metal lower cam belt cover is damaged and I can't find the timming marks to set it before stripping.
Use the TDC mark at the transmission... it is more accurate than the mark on the pulley.
I have a leak near the fuel filter. What is the square box next to it (on the right) with a single cable leading into it? Looks like it goes to the transmission maybe. Also another culprit could be on the opposite side of the evap purge valve. Which cable/valve is that? Thanks!!!
Shifter cable next to fuel filter.
Throttle cable / kickdown switch next to purge valve.
"Culprit"... for what? What's the issue / problem you are trying to solve?
Thank you once again for the videos! On 1:37-1:38 you looked at the battery. Over it, there are two hoses (like) or cable channels that came from inside the drivers cabin. Can you tell me whats those? One of them is leaking oil and i'm trying to know whats that. TIA
It is easier for me to know what you are talking about... if you post a video on your channel so that I can see.
Great and helpful video. I have a new to me 93 2.5 EV 5-speed. It idles high and pulsates between 1500-1700 when warm. I notice it stops pulsating when I turn the PS pump (which is also making its own noise). Could it be the PS switch like you mention @ 4:45?
NO... the PS switch (when it goes bad) will result in a low idle. If the vehicle has AC, check if the heater controls are set to AC. If yes, change the settings so that AC is off. When AC is active, the engine computer raises the engine rpm to compensate for the AC load... if the AC is not working, then there is no extra load on the engine... that would warrant the engine computer to raise the engine speed.
If the vehicle does not have AC or turning AC OFF does not make a difference... then you would have to start with checking the basics. Cam & crank alignment, ignition timing, base idle speed, correct operation of the idle stabilizer, vacuum leaks etc. Thank you for watching!
He i have vw t4 and i'm gettingdark black smoke and i have no idea why.. do you have any answers for such thing
Thank you
Gasoline or diesel engine?
I assume gasoline... check the vacuum hose that goes to the ECM. If the hose is broken, the ECM will add too much fuel. In that case, the engine will run rough at idle, but will seem to run fine under hard acceleration. If it runs rough under hard acceleration as well... check fuel pressure and O2 sensor output.
Where was the water pump in this run through? I didn't hear you mention it other than the aux water pump.
The water pump is driven by the timing belt... so it would be behind the timing belt covers. The water pump can be seen in the following video link at 19:25 (where I remove the belt from the water pump):
czcams.com/video/h1Wc_mP9Jgk/video.html
Can’t find the oil pressure sensor for my 93 eurovan 2.5l
You obviously haven't checked at the 3:33 location.
I have a problem with my 96 2,5 TDI 75kw power steering when I turn wheel to the left sometimes its feels like it is harder to turn and it "jumps" something and then it turns faster to the left. It really annoying... Any ideas, thanks. :)
If the belt tension is correct, then the problem might be with the steering rack itself. Flush the power steering fluid if it has not been flushed in a while. Flushing can remove contaminants that can affect / obstruct fluid flow.
Hey! Great vid. At around 1:05 you put your left hand down to this black tube that goes to the left from a black circular cap. Can you tell me what that is? Mine is disconnected and has yellowy oil residue in it, but the van still runs. Thanks for any help you can give!
That's the PCV breather hose... it is connected to the PCV valve at the right side of the valve cover and is connected to the air intake tube at the left side of the engine. Yellow oil mix substance is oil that has been mixing with moisture / condensation. Remove the hose and the PCV valve and clean them... so that the engine crankcase can breathe correctly again. Odds are good that the diaphragm inside the PCV valve is broken (from old age). If you can source a new valve, replace it... and the rubber grommet that the valve sits in on the valve cover.
Thomas EXOVCDS you’re awesome thanks
@@joshwashposh thank you for watching!
Do some eurovans not have a cabin air filter?
Eddie Lin older ones don't.
Hi
I have a problem with high pressure in the cooling system. So far I have replaced the head gasket, thermostat and checked the patency of all hoses. I don't know what could be wrong next. Maybe you can help me, thanks in advance for your answer. 2.5 AAF 110 engine 1994r.
When the engine is running, is coolant returning / flowing back into the coolant reservoir via the return hose on the bottle?
Remove the reservoir cap, start the engine and look into the bottle. If you don't see coolant flowing, open the throttle with your hand to increase engine rpm. Let me know what happens.
I can't help if you don't reply.
@@EXOVCDS Problem solved, I didn't know that there was another return hose coming from the radiator, someone before me plugged it. I installed a new cable and everything went back to normal. Thanks for your willingness to help.
Thank you for the update.
I noticed there was not a shroud / cover underneath the van. Was that just for the video or is it not needed? Seems more convenient. Thanks
90% of the Vans I see have Belly Pans... although it's not really needed, it can provide some protection (from gravel, water, other debris from flying up into the engine bay / belts) and also helps with noise deadening. For a DIYer, it might be better to leave it off... for quicker / easier access, but if you have a Belly Pan, I'd suggest leaving it in place.
@@EXOVCDS hey man thanks for the reply, this is the 1st time I have ever subscribed to a channel and didn’t expect that.
I’m a new euro van owner and appreciate the response / info!
Great video!! I have 1992 euro camper, where is the temperature gauge connector located? big thanks!
Watch & listen at 4:04 to 4:10.
Oh,Yeah, thanks Thomas. On top, what’s that long yellow wire cable between coolant reservoir and battery? Only one long yellow wire cable….Look like it goes to dash….thanks.
Speedometer cable.
THANKS, Thomas!
Hello Great videos you do.I have one of these and using Vcds comes up 1087,basic settings not done.TPS is not adjustable,any experience of this please?
Standard or automatic?
Thanks for reply.Automatic,replaced Tps,still the same.
Go to ECM measuring group 001. With the following prerequisites set... click on switch to basic settings.
PCV hose removed from PCV valve, coolant temperature above 85c, idle speed of 775 to 875, CO 0.3 to 1.2%
After ECM basic setting has been set. Go to TCM measuring group 000 (engine off), click on switch to basic settings, depress throttle pedal fully for 3 seconds, release pedal and click on switch to measuring blocks.
Many thanks for fast response,can’t wait to have a go tomorrow.Let you know what happens if I may?
Sure.
Hey Thomas, i have a 1995 Eurivan with a no sognal code for both the TPS and IAT sensors. Any ideas? I beleuve both semsors were just reepla e and the car has no power when accelerating
Check the wiring accoding to the wiring diagram in the service manual.
@@EXOVCDS any clue where I could find it? Been struggling to find a matching one online

On Digifant Multiport FI -Component Layout for 1993 Volkswagen Eurovan # 3 is "Heated Oxygen Sensor (HO2S) 3-pin connector.
I couldn't find one in my vehicle.
Also what is on that diagram marked as "Intake Air Temperature (IAT) Sensor (G42) - You called CO adjustment pot (it's on 1:19 ) - correct?
Also, I'm puzzled, is it a MAF on this vehicle? Thanks.
O2 sensor is in the exhaust downpipe above the steering rack. Find the sensor and follow the wiring to the connector. MAP sensor is inside the ECM... no MAF sensor. A vacuum hose runs from the intake manifold to the ECM where it attaches to the MAP sensor. Some engines had a CO pod in the intake hose, some just a temperature sensor. One has 3 wires, the other 2.
@@EXOVCDSMy Van have bad idling. And It's dying when I use extra power, such as raising power windows, brake lights etc. Also my ECM relay clicks like crazy. I changed it for new one, but it didn't make a difference. VCDS-Lite gives me 00523; 00522; 00519; 00518; 00525 faults codes. So, I want to do simple things first before possible changing MAP. Also I never clean anything for years, so it can't hurt anyway. So I'm planning to clean Throttle Body, and change O2 Sensor, I was looking for MAF to clean... But since it's no MAF Sensor there, what else I can easily clean/replace and hope for improvement? Thanks a lot!
@@alexivanov7567 once you find the o2 sensor, disconnect it to see if things change. Can you view coolant temperature with obdeleven? A faulty blue 2 wire coolant temperature sensor is a common reason for running issues with older vehicles.
@@EXOVCDS How many O2 sensors 1993 Volkswagen Eurovan MV has? I wanted to order O2 sensor from a web, but since I had 8 results , I called them first and asked what's the difference? But first thing they asked me if it UPstream, or DOWNstream? I didn't know I have 2 of them. And I'm still not sure that's the case. If so, do I need to change them all at the same time? Or one of them in priority in order for change?
P.S. I don't have OBDEleven, I only use VCDS-Lite 1.2 Sale person in Ross-Tech admitted what on this old vehicle even on a Pro software I won't be able to pull out much more then on basic version. Is it any other way to view coolant temperature in my case? Thanks.
93 has one (up stream) o2 sensor.
VCDS Lite should not havecany issues showing coolant temperature. Usually visible in measuring value block / group 001.
Thanks, very helpful informations 🙏 sorry my English is not very good. I have a vw transporter t4 1991 model. The ingine turns off when i stop the car. Do you know what is the problem?
Which engine? Does it happen all the time or only when the engine is warm? Standard or automatic transmission?
@@EXOVCDS 2.5 L. It happens when i start to drive and when the ingine is cold. After driving half an hour it doesn't happen. The cars has olso irregular idle all the time. Maybe it's relay ingine control?
Standard transmission.
@@sam.721 when the engine is at idle, does the idle stabilizer on top of the intake manifold buzz? Put your hand on it to feel the buzzing or hold a screwdriver against it and put your ear on the screwdriver handle. If it does not buzz, check fuse 15 (10A).
@@EXOVCDS thanks, I will check it. 🙏
PLEASE THIS IS VERY URGENT SIR.. I JUST BOUGHT A T4 VW BUS JUST LIKE THIS ONE U DISPLAYED. HOW CAN I CHECK THE ENGINE NUMBER .. (NEED THE INFO FOR REGISTRATION)
Sticker on the timing belt cover... 3 letter code.
Hi, does 1993 Eurovan 2.5l AFF engine Hase EGR? If yes where is it located? Thanks
AAF does not have an EGR system.... ACU engine starting 03/94 had EGR.
@@EXOVCDS Thank you!
Hey Thomas - I have a Eurovan 2.5 petrol Automatic in the UK (LHD!!)- I can't for the life of me find the oil filter....where the hell is it?? Thanks in advance
Under the exhaust manifold on the right hand side of the engine... can be seen here:

Accessed from under the vehicle... above the right CV axle.
THE GERMAN GOD
Tell me who / where... and I shall kneel!
Power steering stall issue is happening on mine made up I saw this. Did you say this is down to a fuse. This van has disconnected the sensor?
What year is your van?
@@EXOVCDS it's a 1995 acu 2.5 5 cylinder
Your van does not have the Power Steering pressure switch on the same fuse as the 92 - 94 vans. In those vans, when the power steering switch fails, it can blow the fuse, causing the idle stabilizer to not work.
@@EXOVCDS ok so is that to say I'm wrong it's something else or the power steering is just going to keep blowing a fuse on the idle? Sorry just bought this cant find a mechanic who's interested.
@@lifegpt Key ON engine OFF... put your hand on the idle stabilizer. The stabilizer / valve should buzz. If you can not feel the buzzing, put a screwdriver on the body of the valve and place your ear on the screwdriver handle. Does it buzz? Yes / no?

HI have 95 Rialta with G71 code ,replaced vacuum line but not sure other end connect to right place .Looks like it is connected to air injector pump,is that correct?
One end goes to the ECM and the other end goes to the nipple on the intake manifold (there should be a plastic T that also feeds the fuel pressure regulator with vacuum).
@@EXOVCDS ok i guess mine not at right place. what would connect on air injector pump it has two nipples
It doesn't matter where you connect the vacuum hose as long as it is a "manifold vacuum" source. I can't see what you see... either post a video (post link to video here) or send me a picture (click the fkh161 link in the description and then click on "tool request") via email.
@@EXOVCDS ok sent email its the blue line
Got it.
Where is the clutch drain plug?
I have never heard of a clutch drain plug. A standard transmission has a gear oil drain plug... should be visible under the transmission close to the differential housing. 17mm allen tool required. The fill plug (also 17mm) is located at the front facing part of the transmission just below the starter.
www.thesamba.com/vw/gallery/pix/1916574.jpg
1 is fill 2 is drain.
I've got a Eurovan having the same issue as the guy that started this thread: www.thesamba.com/vw/forum/viewtopic.php?p=9624502#9624502 some sort of random CEL comes on and it dies situation. Any ideas? Also where is your shop at if you're near me I'm heading on over.
Sorry, I don't have time to read other threads,
Post specific about your issue here and I will try to help out.
- year & engine?
- fault code(s)?
- stalls when? Idle, while cruising?
- how long after it stalls will it start again?
- post a video of the issue on your channel so that I can see & hear.
Hi, broke down with mine, it's a 95 Winnebago Rialta made on a Eurovan chassis. The engine starts but idle is bad and stops. The fuse 15 always blows when the ignition key is turned on. Disconnected the computer but Fuse 15 still blows... Wiring diagram says there is the Idle Air Valve, Evap valve and EGR valves are on this circuit. Can you tell where the wiring harness passes to go to the fuse box inside the T4? It's stock a long way from home, going back there next week to try to fix it... it's a 2500km drive. It's at a VW dealer but it's been there since a few months and they won't really work on it. I know it's one of the valves or the wires... let me know if you have any idea! great video btw!!! Thanks!
Will it run fine if the throttle is kept above idle?
A common problem (that I recently mentioned in one of my Eurovan videos) is the Power Steering Pressure Switch shorting out, causing the idle to be low / stalling when turning the steering wheel. Disconnecting the PS pressure switch will stop the fuse from blowing. If that is not the case, then continue with the other items on that circuit.
If the engine does not keep running with the throttle above idle, something else is going on.
Sorry... blond moment... I didn't pay attention to the video title. This is the video where I mentioned it.
I do not have any Rialta experience, sorry... physically tracing the wires / harness would be the only / best option.
Yeah, I noticed the Power Steering problem you said in your video... it will run when the throttle is kept above idle, runs weird though, and engine will stop when idling... will stall even if I don't turn the steering wheel. But that's interesting, I'm surprise it's on the Fuse #15 and not showing it on the wiring diagram. Certainly something I'll check out on it. For the wiring harness, do you know if it passes in the front fender or directly under the hood? Cause I know it's been hit before on this fender and if the harness passes in it, could be that too. Thanks for the PS Switch hint.
Oh, well, the Rialta is built on an Eurovan, which is a T4... so it's pretty similar for everything not camper related :)
Just found the PS pressure switch disappeared in 1995, so mine might have it or not... surely something to check when I get there! :)
Hi, IAC valve?
What about it? Where is it?
On top of the intake manifold. Idle stabilizer is what I usually call it... sorry.
Quick question. Where is your shop? I would love to give you some business.
I'm in BC Canada. I'm sure there are better guys in your local area.
@@EXOVCDS I don't know about better! You rock bro!
Your amazing thanks for all your info. I have a 93 weekender and I'm dealing with an overheating issue, (needle to 3/4) I have done all the recommended fixes, fuses, resistors packs still I'm not getting low speed on the driverside but that sounds like not a big deal. Also, there is a resistor behind the headlight the one next to the coil. can you tell me what that one does? thanks.
Watch the following video... test / check things the way that I did. Let me know what you find. I'm not 100% sure about the resistor next to the coil (I'm drawing a blank).

If your grill is a "one piece" (you don't have a small cover that can be removed, then you have to remove the whole grill. Let me know what your grill looks like and I'll be of more help, should you need it.
One more thing... the radiator fans have "cooling fins" on the engine side of the fans. Those fins are controlled via a "thermostat". If the thermostat is bad, the fins will not open... causing lack of airflow through the radiator. Let me know what the fins look like (flat / closed or partially open when the engine is warm).
You know another about it
What do you need to know?
Egr were ?
What year engine? What model car? Please?
@@EXOVCDS is a vw t4 9 last 2002. 2.5l gasoline. AVT is the engine code. wonder if there really is a valve on them. and where do they sit? for the engine light is on but it goes well.
has also changed the Oxygen sensor front and rear.
The EGR valve (if it has one) is located under the coolant reservoir... mounted to the side / back of the intake manifold. Looks like this:

A petrol engine on a vw transporter...
Disgusting
2,5tdi or 1.9td are best engines for that van, depending on your needs.
Most people in North America like the quietness of petrol engines (compared to diesel of that era)... then again, it was up to VW as to what was brought to North America (staying within the Department Of Transportation Emissions guidelines).
@@EXOVCDS The 2.5TDI in some cases is also good quiet engine. The 1.9TD is the loud weak one. However since over the pond petrol also is a lot more cheaper as I have heard, I guess having a petrol van can be justified. The bad thing is however, that eurovans in us got the luxury interiors(some of them) along with AC for all passengers, leather seats and electric windows, but eu versions quite often had only the basic setup. Earlier versions did not even have power steering here in europe.
@@angryrepairman5275 Yeah... the markets are quite different.
