GTI cutting out, oil light flashes

[firstgolfgti]

I don't have a 16v only the 8v , but after suffering from the same annoying fault might be able to give some quick pointers. It would seem the easiest and cheapest has already been done in the form of changing the ECU Relay with 30 on it. Next up is the fuel pump relay mine had 167 on it but this might be different on the 16v not sure. Think mine was £15+vat from the VW dealer.

Its always worth getting the relays direct from your local VW dealer. Could be worth looking at the throttle body housing a quick squirt with carb cleaner gets rid of any build up of grime put a rag undearneath stops any drips onto manifold, you need to remove the main breather hose from the air filter pair of gas pliers needed (well for mine anyway). From there a no. of sensors and the like I changed the crankshaft sensor and touch wood (frantically touching my head ) its been fine hasn't cut out yet.

I know theres 29 odd pages but it makes a damn good read very interesting. Think the crankshaft sensor from VW is in the region of £125+vat so be warned I got mine off ebay original part in sealed bag but for only £40!

I'm sure other people with 16v's could give you some advice - good luck!

Both the 8v and 16v have the same #30 ECU and #167 Fuel relays in them.
The crank angle sensor part # is the same in both cars too

 

If these two relays are stuffed VAGCOM will not pick it up, replace the #30 relay first with a geniune one and take things from there...

Though the cutting out seems to of been solved on my car, the revs drop while i'm driving then pick up again and normally happens from a cold engine. This never happened before. I think it's more electrical related than fuel.

I can hear one of the relays clicking can't tell which one fortunately i've still got a spare one of each (30 & 167), put them in but is still doing it. I'm taking my own advice and reading back thru all previous posts see if I can pick something up.

Might invest in some new HT leads and maybe an ignition coil if I can track down a cheap one. Cos its intermittent sounds more like an earthing problem??   oh yeah checked the throttle body - still nice and clean.

Check the earth strap to the gearbox and the one going to your relay box (under the dash)

Coils are common to die on mk3s too
New HT leads and a new dizzy cap/rotor never hurts

But there are subtle differences between cars with this cutout problem, an easy fix for one can turn into a major for another  Take the time to have a look back at what others have done from page 1

The dizzy got changed recently so i'm 99.9% confident its not that. I've found the earth strap in the fuse/relay box, the other one to check is from coil to engine block i'm gonna get some HT leads at lunch so will see.

firstgolfgti have you swapped the temp sensor and checked all the breathers as these seem to fail and give the current symptoms your stating....
and for everybody..... don't rely on vagcom being correct. mine has had a new air mass sensor as vagcom said it was faulty and in the end it was a split breather hose...

[firstgolfgti]

where is the temp sensor located?

If I found a faulty earth strap, do I get a flat braided one as installed or go for a nice thick black bit of cable with heavy duty crimps?

On the breather hoses I've had them all off check for blockages and splits they seem fine.

[firstgolfgti]

Found the temp sensor.

Two questions:

1. Can I just take the temp sensor out or do I have to drain anything first.

2. Do VR6's and all Corrado's suffer from the cutting out stalling?

Hi people,

My wife has got a cutting out problem with her 96/P 8v GTI. It usually occurs when the car is cold. It can happen if you blip the throttle and the revs drop and die, it happens when approaching junctions, even happens when you are accelerating (however when accelerating it feels like the ignition is turned off and back on again). Also the car can be idling quite happily at a stand still and just dies!!

Not sure where to start looking for the cure. Have replaced the ECU relay as this was the fault of a previous cutting out problem 6 months ago, but now have another!! Noticed as well that the coil pack has been changed. I know that cutting out problems are common, but just need some guidance.

Any help is appreciated thanks.

Right.
Happened again this morning. Exactly as before. There is a pattern emerging....
First, it's raining. Doesn't seem to like it.
Second, it's while pulling away.

I had bought a replacement ECU relay which I hadn't installed as it was running ok, and I wanted it to happen again so I could positively identify the relay as the fault. Having happened again, I immediately switched relays. After a little sputtering it started, but running it was bogging down as before. Got it back home and let it idle. It was idleing horribly with a very gradual drop in revs before dying. Then struggled to start, at which point I left it.

Any ideas?
