got a #30 relay yesterday from ECP ?10.03 Gray and made in germany. Put it in and it drove like a dream? . Straight away i could the difference, car felt smoother, queiter and more responsive.Also the mpg went up to 36 from 30.

However, this morning on the way to school (dropping the kids off) it cut out again? and the mpg stayed at 30.

I had a problem with the MAF causing juddering on my P reg GTI 2.0 8V for about 3 months, and in the last month of this, it also started to cut out when I stopped at traffic lights, etc. I changed the MAF yesterday, which fixed the judder, but the stalling still remains.

I don't get the oil light coming on, and it never stalls at speed, so I think I can count out the relay. However, would I be correct in assuming that running with a knackered MAF for 3 months may mean that my throttle body is probably caked up with crap? I'm going to try and give it a clean out in a min, although I don't really know where to start...

I'll try and get some photos!

Maybe you guys can help me my 8v mk3 GTi cuts out when cold if left at idle. Sometimes its okay on start up but very rarely. Can be quite dangerous when you dip the clutch at a roundabout in rush hour traffic as you lose all power steering when the car stalls.

The fault goes when warm any ideas relay etc???

(there is no fault code)

i cleaned the throttle body the other day and so far it drives ok  . So i would suggest doing that first as it wont cost anything apart from time and effort!!

My P Reg 16V is juddering in normal driving, sounds like gavcradd's problem, can someone tell me what a MAF is, and where do I get one? Thx

my mate who was a vw tecnician a few years ago had the same problem on his vr6,he replaced all the ususal items to no avail,he eventialy traced the problem back to the oil presure switch on the oil pump.

Hi all

after reading the this thread (and the ones linked 2 it) i now have a list of several things it could be that cause this cutting out issue....

Of them i have changed the ECU relay, to no avail (car cut out on breaking 2hrs after installing it)

I was wondering what to try next as im not keen on getting ripped off by VW - especially as they dont really seem to know the actual source of the problem...

there seems to be a good shout for this Ecotek power boost or cleaning the throttle body..? just wondering if anyone has actually ever fully solved the problem...?

cheers
