GTI cutting out, oil light flashes

[STOMMO]

Now then. When I operate the air con my revs drops by approx 200 and it wants to stall. But then it just picks up and idles at 650ish. Is this normal or should the revs rise? By the way I had all this stalling and cutting out stuff. I was pulling my hair out, spent sh!t loads of cash and  then the no. 30 relay sorted mine. I know what you are going thru, you just don't trust the thing and are just waiting for it to happen. And you just know its going to do it at the worst place/location you can ever want!!!!!!

Hahahaaa! Well, I think I've threatened the car with a bit of jiggery pokery and it's not doing it now. I kid you not, the bu66er's right as rain. Just to be on the safe side, I bought a relay today (was £10.89 all in) from Main Stealer.

But, my aircon makes the revs dip ever so slightly until the 'automatic anti stall' kicks in and the revs go up to about 1100 on idle. Normal idle is 900ish.

Appologies b4rks,

your right, the # 30 relay is to the right of centre (top) - should have double checked before posting !! 

hope this has not caused inconvience to anyone !

Wahey, changed the crank sensor (which was worn through - exposing the wiring) and it hasn't cut out since (touch wood). Pricey job as it's stuck behind the front engine mount but if the ECU relay doesn't do the trick, check the crank sensor.

  Hey Everyone..... Been following this post for about 4 weeks as i have the same problem with my MK3 2.0ltr 8v GTi........ but its finally been fixed!!

I replaced the ECU,Fuel and Releif Relays! cleaned the throttle body, changed crank sensor, and still the same problem!

BUT FINALLY..... I took it to a friend who is a VW/AUDI SPecialist! he did all of the above work on the cheap as he had never seen the problem before! he checked everything and finally he found the problem!
When the Ignition it on start it sends an electrical surge to the fuse and relay box..... hence causing the realys to overheat! this can be fixed by just replacing the relays if the surge wasnt too bad! but like on my car this surge quite big and was also caused by faulty parts on the starter motor!
Repalced the starter motor parts and now its fine!
I will get a list of parts that were replaced by the end of the week!

Hello everyone
My 1992 Golf VR6 has the same cutting out problem, but no oil light comes on unless it cuts out at a junction. It splutters when im driving then kicks back into life. Then a new one yesterday , when stopping before i turned engine off it tried to die then shot back into life upto about 1500 revs

Will these relays be worth trying on mine, or is it just 8v

Its had a new cranck sensor and new fuel pump relay, i also cleaned the throttle body, a new lamba probe.

Help

Thanks

okay, I know this is an old thread and I know it's probably not read all that much but this is seriously driving me mad, how can VW let this happen?

I've replaced relay 30 with the grey one, replaced 167 with a new one. It's still doing it. It's an embarassment to go anywhere as it keeps cutting out and refusing to start. Sitting at the roadside for ten minutes.

I start uni again in two weeks and without this I'm doomed. I've got a 97 colour concept with an AGG engine, I'm assuming it's just on this and I can't really afford to go the path of replacing everything.

it's not the throttle body or the breather pipes as I've cleaned out both of these thoroughly. I cleaned the dizzy cap, rotor arm, these were kinda filthy but this did nothing. There is a spark coming from the HT's. The plugs have been replaced recently, about 1k ago.

I'm thinking that someone may actually be onto something when they say the oil pressure sensor hidden behind the oil filter, surely this would explain the oil light coming on and it only happening when it reaches a certain temperature ?

My relay 30, not the old nor the new has never been excessively hot and changing it did nothing. It's only cutting out when I'm driving it, not when it's left to idle as then it's rising up and not proving any issues.

This is really stressing me out and I'd appreciate any help given, I'm really loosing hope in my car. I've done 10k in it since I bought it so my saving grace is that I know I probably didn't buy it with this problem, should I check the wires or anything at the sensors? Where are they located? Should I kick myself hard. I love my car, I'm not going to part with it, I just wish it would show me the same kind of love back.

P.S. For good measure, here is the machine of love.

Thanks to everyone on this site...

Just replaced ECU relay (the one with a big '30' on it) as mentionted in the above posts...

sorted my problem straight away. Only cost me a tenner too!

My car still occasionally dies at idle but that's because the injection system and sensors need cleaning.

Do you think maybe the strain of stalling at cold might have caused the relay to fail?

After posting that yesterday, I drove home with no problems at all...

then the little f**k*r did it again, this time on a very busy part of the A3 in london with no tossing hard shoulder. managed to coast off the road into a car park and started it again, then revved it until it heated up. It seems to be okay now, but that was the last straw...

I'm buying a Honda S2000 instead!
