Been having loads of grief with my golf again!!! Its been cutting out and some times not starting since i got it. I was told it was the immobilizer so i had the alarm serviced. Since then it wouldnt start(nothing going to the starter) so i changed the ignition barrell as it was dodgy, it started no problem fine for a few days. Next thing its running fine then starts cutting out on the motorway like thers no fuel supply then not starting for 5 mins!!!!girlfriend and kids in the car not happy!!!!!! So next i cleaned the throttle body out etc and changed the fuel pump relay n put some fuel treatment in the tank. Been fine for a few days but just cut out at the lights and wouldnt start again for 5 min. Had to push the f**k*r again its doing my head in. any ideas please. Could it be the coil pack? frustrated golf owner, griff
-
Could be the dizzy?
-
coil mate! defo..golfs seem to burn them out fast!
-
my coils on the way out, if i ever go out anywhere in mine and it starts raining, i dread trying to restart it! feels like its running a bit rough at times too.
-
what engine is it? could be crank sensor if 16v or later 8v
-
As above, on my 16v it was the crank sensor. I replaced everything and in the end it was the crank sensor.
-
would check crank too if it has one. Mine looked like:

How do you have your alarm "serviced" out of interest?

Yeah cheers bud gunna check the coil pack first if not i think it could be dizzy
-

Its a 2.0 8v (agg) thought it might be that before when my rev counter went crazy but there is no crank sensor its built into the dizzy so could be this. Cheers bud

its a toad alarm i looked them up on the internet and they sent out some clifford blokes. It was about £150 so not cheap but it all works now central locking, siren etc. Had to get it checked out because everyone was saying it was the immobilizer (including qualified mechanics)
-
the AGG has a crank and a cam sensor. The crank is under the oil filter in the block, and the cam as you know is in the dizzy.
Would check the crank sensor wiring out if it was me.

Cheers bud will check it out, away working at the moment but determined to sort it when i get home. got a spare coil pack and gunna look at the dizzy. ill check the crank sensor too. gotta get this sorted sooner or later. nice one
-
I'm going to say it's either coil or crank sensor. Before you do anything though I'd suggest getting it scanned on vagcom, it will determine the fault if it's a sensor or wiring.
-
I wish it did! None of my faults (including my shorting-crank-sensor-wiring) shows up on vagcom. In my experience the mk3 ECU isn't clever enough to log non-critical faults.
Worth a try though - you might be lucky

Thers a vw specialist down the road, he was gunna charge me £50 to put it on his vagcom for an hour but another garage said it wouldnt show up, he said same thing coil or dizzy. ive got a coil pack and its only a couple of bolts so its no bother to try this. Cheers for the advice this forums been sh!thot
-
vagcom for an hour? What's he gonna do sit there an hour bored? It takes 2 minutes to scan it.

I know bud itold him to do one
-
ecu relay 167 if you have one?
-
good thought - replace no.30 (ECU) whilst you're there. Cheap enough from VW
James
(updated - thanks rubjonny)
-
30 is ecu relay, 67, 80 or 167 is the fuel pump, and yeah as above AGG does have a crank sensor :)
-

im running an 8 valve 1996 P reg 1.8
-
dont think the 1.8s ever had a crank sensor, its all run off the dizzy so could be hall sensor fault instead
-
ecu relay 167 if you have one?
cheers bud ill av a look, hopefully be sorted soon gotta few things to check. changed the fuel pump relay allready but didnt think about ecu relay. nice one griff

allrite bud me again, golfs still driving me mad. its a 1997 2.0 agg. ive changed the coil pack and ecu relay. also checked the dizzy and cant see anything wrong with it. Running fine for a day then cuts out again wont start for 5 mins, ie when its hot. still cant find crank sensor, nothing in haynes manual!!! looked under the oil filter,there is a probe but i thought that was an oil sensor. all the problems point to crank sensor but not sure if its got one. also do u think it could be the fuel filter? running out of ideas. cheers for the help so far GRIFF
-
AGG defo' has a crank sensor. Its in the engine block under the oil filter, and the comes out, round the filter bracket and into a connector on the bunch of loom near the dizzy.

[/quote cheers fella will definately check it out. changed the ignition barrell recently and lost the key at work yesterday, fuming. cant start it now, i put the original barrell back tonite and swapped the black box over but wont start at all now. Even bridged the starter and solenoid to bypass it and still wont start!!!! seriously stressed, the only thing that works properly are the hazard lights!!! Griff
-
hello mate me again found the crank sensor and looks real shabby think this could be the main problem with it cutting out gunna get a new one. my ignition barrell is dodgy aswell, it will start now but just of the swich(blackbox). ill let u know how i get on cheers 4 the help, griff
-
i was going to sau ecu but you guys got there before me. only way to check it properly is to let it idle get it to temp and then rev it lyk a beehach! it will cut out connect vag com and ut will tel you no signal from ecu it will be the ecu relay (had same prob going down a hill engine clunks of no brakes or power steering :shocked:
-
should point out that rev'ing and engine with no load is not good for it.
J
-
I bet you its the crank sensor ... your symptoms just so much like the crank. Silly rev' bouncing and cutting out.
I spent nearly £800 fixing/replacing so much stuff under the hood, and did the crank sensor last.
I also, got a NEW ECU reprogrammed and what not ...
Absolute headache electrical faults are, but when sorted you have your self a solid motor again.

hello bud, ive changed my crank sensor when i removed it was damaged, bare wires etc. Got a new one from gsf. Ive fitted it but im still having same problems. it will start and idle for 10 min then cut out then wont start for 10 mins when its cooled down!!!!! Ive changed the coil pack,ignition switch, fuel pump and ecu relays,cleaned electrical contacts,cleaned the throttle body added fuel treatment to the tank. ive looked at the dizzy it looks fine but may not be!!!!! Dont know wot to do might just take it to vw specialist, he wants £50 just to put it on vagcom, could be expensive. cheers Griff

yeah its not good mate bit of a death trap really no brakes etc. i swapped the relay for one out my 1.6 and no change starting to think it could be the ecu. do u know if this is common? cheers griff

yeah youre right there mate, gunna have a new car by the time i find this gremlin. when i saw the state of the crank sensor i thought its got to be that but ive replaced it and its still giving me grief, headache!!!!!!!!

Hang in their, youve pretty much replaced quite a lot ... so keep going. Trust me, its worth it in the end as you know youve pretty much eliminated most if not all the problems for a very long time!

HAPPY DAYS........ As u know been having problems with cutting out etc, took her to the vw specialist and put her on the vagcom. dodgy power supply relay to ecu, the dealer said its common the solder goes hard and breaks up. only charged me £30 to scan it (quoted me £50 last time) fair play, seems to be sorted now fingers crossed. £72 for the lot, im well happy. cheers 4 ya help people. nice one griff
-
this is the same prob im having with mine, ive replaced the crank sensor and relays, but it still keeps cuttting out after about 10 mins when its warmed up, iv put it on a machine and its come back with nothin ? do u know where the power supply relay is bud ? as ive replaced the ecu relay number 30 and its not that, its really doin my head in :cry:
-
sorted it :smiley:, it was the crank sensor, the new one i had fitted, hadnt bolted all the way in when i fitted it, went to take it out and the bolt was loose :huh:, tightened it back up and it seems to be ok now, bit annoyed that i spent about 100 quid on parts i didnt need tho, got spare crank sensor, distributor, relays and sensors, doh
