GTI cutting out, oil light flashes

[neo2]

  Just thought i would post my results for you guys, went to VW yesterday and ordered a new relay, and it came in today, at a price of £8.14. all in.

Now the old relay was the blacke maylasia made relay, and the new one is a made in germany grey one.

Ok i fitted the relay and have been out helping my mate out collecting sales stock for his garage it was an ideal time to use the car to crack on a few miles, so i am glad to report after 171 miles done today the car never missed a beat.

So its looking good, touch wood, i opened the old relay and could see nothing un toward.

Just thought i would pass on my results, will keep you informed over the next few weeks or so.

Cheers

Hi everyone this is my first time to the site, I have a 97P 2.0 8v Gti that is also suffering with the same cutting out problems. Oil light flashes revs drop to zero and the car cuts out. So far in the last 3 weeks i have replaced the coil pack, plugs, and leads. Still not cured, had a diagnostic test that showed no faults. Mechanic changed the ignition switch all was well for 400 miles then cut out again in fast lane M6. Took it back and had retest which showed intermittent fault on the speed sensor (crank). My car is not fitted with this so the equivalent is the Hall sensor within the distributor, had the whole thing replaced and a new fuel relay just for good measure. Just travelled 250 miles on the motorway with no problems, went back out on my way to the VW garage for a new ECU relay and it cut out twice again. I have just replaced this relay now and checked the throttle body and replaced the breather hoses, Any other suggestions would be gratefully received as i think the next step is to burn it out!!!!!!!!! Many thanx in advance.

You aint stated that if you have replaced the relay number 30 in top row of the fuse box,

If you have not and its a black one i suggest you try that, the new one is a upgraded part and it controls the ECU, for the engine the relay you will replace it with will be grey and of german made quality, the black relay is malaysian crap, ive replaced mine and it appears all fine now, as it did within 10 miles from cold everytime.

Worth a try under a £10 as well.

Mine was doing exactly the same as yours 60- 70 mph or any speed, and it was though you had turned the key off and you would be out on a limb, it would always restart sometimes straight away others i would have to wait upto 10 mins etc.

hope this helps cheers Rob

3.DONE THAT AND ALL OK,NOT ENGINE REVING TO 1400 ON TICKOVER WHEN WARM,I'LL GET IT LATER I THOUGHT.
4HEAVENS HAVE OPENED,NO JACKET JUST MY KEBAB IN HAND AND IT'S DARK OCLOCK IN A DISABLED SPACE ,I JUMPED IN STARTED AS NORMAL THEN CUT OUT HAD A QUICK LOOK AND SEEN NOTHING WAITED 5 MINS THEN SAME AGAIN,THEN HAD TO CALL UPON MY YOUNGER BROTHER IN THE 3 CYLINDER PIMPED CORSA FOR A LIFT:cry:
5.GOT A TOW HOME THE BATTERY WAS FLAT BY NOW,GOT ANOTHER AND TRIED TO START AND I HAVE NO SPARK,IGNITION ON AND TESTING THE DIZZY PLUG I HAVE 10 V AT ONE WIRE AND 11V AT AN OTHER AND I THINK THE THIRD IS AN EARTH,I HAVE ORDERED A COIL AND A NO30 RELAY AND IT'S STILL RAINING,I WILL FIT PARTS TODAY AND KEEP POSTING !

Just  a little thought everyone is on about there cars cutting out and I've read alot bout crank sensors and relays but nobody has mentioned the lambour sensor on the exhaust this daft as it sounds does have alot to do with the running of the motor and being fixed in the exhaust does get extreamly hot and sutted up try giving that a clean with a wire brush but be gentle coz if you break it your looking at £80-100 quid for a new one hey It's worth a try!!

Good point for ruff running, but if you disconnect the lamda it will still run wont it ? albeit crap.

OX1l, i would go for crank position sensor £64 from ECP if i remember.

I think this cutting out issue whole thing is split in to two sections.

1, being cutting out from idle or peatering away till cuts out, combined with intermittant idle speeds.
A, usually idle control valve, air leaks, mixture problems etc.

2, being the total loss of engine spark at any speed ie 60mph, like turning the key off,
A, usually relay 30 breaking down, crank position sensor breakdown, hall effect sensor,

my opinion anyways.

The trouble is, most people have spent a fortune on, plugs, rotor arms, dizzy caps, plug leads, etc, and then a diagnostic fee here and there and a bit of labour, causing bills before you start.

Hi everyone thanx for all the advice on the cutting out problem. I have just replaced the speed sensor (crank) the one that the original garage told me i never had fitted on my car (tossers) and so far so good. Tried all the other fixes that were posted as well but hope this is the end of it now. After spending so much money on the obvious things i think it would have been cheaper to just go to VW main dealer in the first place.

STILL NO JOY ,I TRIED ANOTHER DIZZY,GETTING POWER TO COIL AND DIZZY.
THEN IT STARTED ! FIRST TIME IN A WEEK,TRAVELLED 6 MLS THE NEXT DAY SLIGHT MISS THEN CUT OUT THEN RUN,PARKED THE CAR FOR 1 HOUR THEN IT WOULDN'T START,BACK 4 HRS LATER AND IT WENT FRO A MILE,TOWED IT TO TARDUFF MOTORS 20 MLS AWAY(VERY GOOD REPUTATION) PHONED ALL TESTS NEGATIVE SUSPECT ECU OR WIRING FAULT............I'M BUYING A FOCUS TIL I GET IT SORTED
