GTI cutting out, oil light flashes

[VR6Steve]

Hi an internet search has led me to your forum. I hope someone can help.

I have a Mk3 VR6 and bought a Mk3 GTi 8v 6 months ago for the daily 50 mile round trip to work.

It has a very frustrating cutting out issue which my partner and I are struggling to solve.

When she is about 82-84 degrees on the oil temp the engine cuts out and will not immediately restart. When it happens (which is not every journey), the engine revs struggle and seem to intermittently cut in and out before the engine dies.The oil light does at this point come on. Once the oil temp is up past this, it runs fine.

So far we have done:
ECU relay
Distributor
Plugs & leads
Throttle body cleaned
Coolant temp sender

For other reasons the lambda sensor has also been changed.

I am looking to try an fuel pump relay as the next option. Anything else anyone would recommend trying?

I hope you can help.

Thanks

Steve

Well just about made it back from my local VW dealer after cutting out several times. 

I have ordered a fuel pump relay which will arrive on Tuesday AM.

As a couple of former colleagues work there, they brought out one of the technicians to speak to me. He said from the sypmtoms I gave him and the list of items already replaced, his bet is on a crank postion sensor.

Fingers crossed, especially as it's not a 50p part!

Definitely sounds like your crank position sensor. Get it checked out.

Hi I have been having the cutting out problem after not using the car for 5 months. I have replaced most of the stuff recommended by others on this forum. The car starts fine & ticks over from cold. It will drive without missing a beat for 2 miles then cut out and nothing will start it for 30-45 mins.

Next thing I want to change is the fuel pump relay but I have the problem that my car - a 2000(X) MK3.5 Colour concept convertible - doesn't seem to have a relay marked 167.

Others have said the fuel pump relay is situated bottom right and the Haynes manual agrees but I have relay no. 53 in that position which, searching around, seems to be for the horn or fan.

Anyone else with my model or have a non-167 FP relay? The car has the AGG engine but maybe VW fitted the MK4 fusebox along with the lights, steering wheel etc. ?

Cheers for any suggestions Guys. Also anyone in the Aylesbury area with a Vag-Com wouldn't mind hooking me up?

Well it's finally happened    driving to work in my p reg mk3 gti 8v this morning the car cut out for a split second,the rev counter went nuts and there was a clicking coming from the fusebox,the car has been down on power under acceleration for a while but I've cleaned the tb and the maf but it's not cured the problem,the 167 and 30 relays both get hot but my number 30 is grey but made in Indonesia? could it of been this clicking like mad when the car cut out?

Hi I got the fuel pump relay and fitted it but still the same prob. Also bought brand new distributor from VW which comes fully built - although I'd already changed the cap & rotor arm. But it's still cutting out & refusing to start until it's cooled down.

One constant seems to be that the engine dies when the oil temperature reaches 76 deg. Up until this point it runs and drives perfectly. Anyone got any ideas?

Pleeeeeeeeeeeeaaaaaaaaaaaaaasse !

Ok fingers crossed i may have sorted mine,Changed the relays first and that made no difference then changed the coil pack and cleaned out the throttle body,that made the car run better and smoother but still had the problem of it cutting out randomly,so have now just had the crank sensor changed which i could of done myself had the previous owner not majorly rounded the allen bolt off which resulted in having to take the oil filter and oil cooler off to get it out,  And it seeeems to have cured the problem,its not cut out since wednesday and the oil temp went up to 90 degrees lastnite while sitting in traffic,so id say this problem is down to the crank sensor! but time will tell,keep u posted with an update soon.

Afternoon chaps.

I have a 94 GTI 16v mk 3 which is having this all too familiar cutting out problem. It initially started doing it a few weeks back when driving round town. I had the coil and distributer replaced which appeared to cure it. However after driving from Essex to Blackpool it cut out on the motorway whilst doing 70mph. managed to get hold of a second hand fuel pump relay. Changed this and the car got all the rest of the way to Blackpool without cutting out once.

However on the return journey the car must have cut out at least 7-8 times and is now becoming an absolute joke. I have read through this thread and am struggling to understand what the problem could be. mine doesn't cut out when idle only when driving. There seems to be no pattern to it. I haven't the money to take it to a garage to get it diagnosed and them to say they can't find anything wrong with it!

Somebody please help how do I cure this weird problem. if people could explain what parts I should try I will be eternally grateful!!

Thanks

Hi All,

I've been reading this thread with GREAT interest!!

Got a P reg 1997 8v GTI...

Its only having problems on startup...

When you turn the car over from cold, the red engine oil pressure light will flash..The car starts and immediately the revs drop and it shuts down...

I can get it going again by just revving for about 10 seconds as the revs fall....after this it's fine and will drive perfectly WITHOUT suddenly cutting out.....

Could the cure be the same #30 relay?

The oil light that comes on is the Engine Oil Pressure warning light if I'm right, so does this been the Engine Oil Pressure sensor is knackered?

Thanks!
