Title: mk3 Gti ADY problems
Post by: jimmybryan on 21 July 2013, 00:18

Well i`ll start from the beginning brought a gti 8v (ady engine code) a few weeks back, 1st problems i had was hesitation under heavy acceleration after sorting a vac hose and cleaning the air flow meter out it sorted the hesitation, but it still feels slow! Now its started to cut out at junctions when i dip the clutch at slow speeds(it might be doing it at higher speeds too but i wouldnt know as i obviously change gear before the revs drop down to idle/stall limits).
I have read a few threads on here and other sites and they say it could be plugs-leads-dizzy-fuel pump relay-ecu relay-coolant temp sensor-timing out-throttle body clean-vac/breather pipes-coil, Today i opened the coolant tank and even though it had not lost any water there seemed to be some oil in with my water :S light mayonaise on the cap and small amounts floating on top of the coolant, i done almost 400 mile in her yesterday and the temp guage never budged from middle and not a touch of smoke at any time! (although it did cut out 3 times at junctions on the way). i know theres  so much stuff it could be but if someone has a good idea from reading all the symptoms i`d be grateful of any help.
shame really as its a stunner! totally original 3 door candy white non sunroof model with 89k full service history! but if it carries on giving me this much trouble i might aswell get my toe tectors on and stick a vr6 in there!

Throttle body needs aligning via vagcom. It needs to be done on the ady engine code. That's why it cuts out.

Mass air flow meter by the airbox would cause those symptoms if faulty. Does it run any better with it disconnected? Oil in water could be the oil cooler above oil filter aslong as there is no water in the oil.

Thanks, looks like i need a new maf then, even so when i unplug maf there is no real noticable difference, also on my 400mile trip i averaged 45mpg! will try and lend a mates vagcom and see how things go.

I got someone to reset the throttle body and thought i would give it a clean before it was realigned. Turns out the clean alone done the job and no throttle body reset was needed. Thanks though pointed me in the right direction!

I also have an ADY with similar issues. I cleaned the throttle body a day after buying (4 years ago) so that may need doing again.
I'm guessing the fault code readers can't re align if I were to remove it to clean?
