Is anyone familiar with this problem?
My 1995 T5 Transporter often stalls as I come to a halt at intersections etc. It seems to happen more when the engine is hot. Going down through the gears to keep the revs up seems to help but not always. Work done so far to try to isolate the problem includes:- New spark plugs, Checked for air leaks, throttle body cleaned, PCV removed and idle air mixture valve cleaned, rotor button and cap cleaned, basic idle setting carried out.
The engine stalls while the van is in gear and the clutch pedal depressed.
I am wondering if anyone knows if this is a known problem with this model. I hope someone can help as I live in a country town without VW diagnostic equipment.

95 is a T4 not a T5.

Pull out the relay above the fuse panel that has "30" on it. Check for broken solder joints

Thanks. I'll try that and let you know the result.

Check your throttle position switch on the throttle body.

That year identifies it as aT4,
google search T4 & look at the images to check,
if your headlights are reasonably straight across , it's called a " short nose"
If they are angled slightly from inner edge to outer edge, it's known as along nose,
T5 are another kettle of fish !

Good luck with sorting your problem

Its easy to pop the cover off the relay with a small screw driver

Yeah they are the ones I've seen the most of here,
I have just got myself a 97 dual cab with the sliding rear windows, very soon to be on the road as my daily / work vehicle,

30 relay is just a normal power relay, should be changed every 100 000km. Can make a HUGE difference

No 30 Relay powers up the ECU. When the solder joints crack, it turns the power off to the ECU like you've turned the key off. It doesn't store a fault code, because it thinks you've turned the key off.

It's a power supply relay to the computer amongst other things I believe. A good quality relay under $20

If it was the ECU relay I think that you would have more problems than stalling.

I've had a rough idle fixed by replacing it.

Not really, I believe it's about clean power, as the points get pitted/higher resistance it somehow effects the computer. I am not sure why either, but it gave me customer for life, they hd been to VW nd about 6 other specialists and putting up with a rough idle and very poor running at light cruise for 7 years.

so it sounds like a petrol T4 yeah
so erm put in for a service at a reputable VW service place..
they should sort your woes

I have sourced and ordered the 30 relay. Will update when I know if it has had the desired effect.
Also while looking under the bonnet to get part numbers for other components I noteced that there is a double aperture in the ring gear housing. The two circular 'holes' are recessed as if they should perhaps have something like a double rubber cap to seal them from dust and grit. At the moment they are open. Anyone know if they should be covered and if so what the part is called?

Yep there's a rubber plug for it. It's taken out to check the timing mark on the flywheel

I signed a form on booking the car in which I suspect said that the van would not be released without the bill being paid first. Anyway after I had hung around all day, all I wanted to do was to get home!
