Hi guys im new here , i bought a mk3 2l 8v gti a month or so ago didnt have Mot on it so havent test driven far . i went for mot today and on the way back the engine started stalling/hesitation at about 2500 rpm .
Sooo , After checking ht leads and dizzy , which look new by the way and so does the crank sensor , i started it up running lumpy and was wigglng relays .
I pushed the accelerator while feeling and wiggling and discovered the 167 relay which i believe is the fuel pump relay was clicking exessivly . could this be my problem ??? ..
or could it only be doing it when warm ? 90deg on temp gauge .
help would be gratefull as i need to get two tyres on the car and retested asap thanks :smiley: :smiley: :smiley:
-
have i answered my own question in replacing the relay ???
-
I've never had an issue with the relays, so I'm not sure. But if it is clicking then I'm sure it's working.
One way to check if relays are working. Start car from cold, touch relays after 10-15 mins of driving or ideling, if they are warm then they are functioning properly, if they are cold, you got a naffd relay
check the fuel pump relay and ecu relay, both common to go and will keep cutting out engine.
Also another thing to note, when your car cuts out, does the oil light flash?
-
I did feel both relays for heat and felt a slight difference between them and the other relays , but the excessive clicking of the relay opening and closing when opening throttle was drawing my attention to it being naffed .
The car only cut out / stopped running when i unplugged temp switch . But as the revs dropped at some points when attempting to drive the oil pressure light come on .
FAILED TO MENTION . This seems to be intermittent i can drive the car for about 10 mins and then this happens , turn engine off for a few mins and its fine again for a couple of mins .
The car will sits there on idle fine for ages ,fan cuts in and out . But it doesnt stay on for long maybe 30seconds a time ? Is this normal ??
-
And thanks :smiley:
-
What reg is your car?, and what engine code is it.
The other thing that could cause the cutting out could be dirty throttle body.
Also have you had it on vagcom?
-
If the fans are cutting in, they working fine. And yes it is normal for fans to come on 30 seconds a time. It sounds about right.
-
I believe the engine code to be AGG. The car is a P reg so 97/98
Another thing to mention is that after the car cut out that first and only time its took some turning over to start .
I took the inlet boot off , there was mild oil residue but the throttle body itslef looked relativly clean .
I dont have any access to vagcom unfortunatly .
Thanks about the fan thats one thing off my mind .
Im reading all sorts of other peoples similar problems and i feel it maybe the fuel ounp relay or coil ???

Change that relay as it only ment to click when the car is runnin. Not ment to keep clicking.

As sharki786 has said. Try this first.

Thanks guys ill buy that from local motor factors tomorrow .
One thing. My local breakers yard may still have a golf in , if i was to get a coil from it would it matter if it was a lesser size engine cc ? Im presuming it doesn't matter ? Or are they a different design ?

Might make a difference. Dont waste your money on a coil pack as they can pack up. Replace the relay and drive around if problem is still there thenlet us know.

Don't buy from local motor factors. Try vw for relay, it'll be genuine part, plus they ain't expensive at all.
-
Getting a genuine relay would be a problem due to not having another car to get there as just take my E30 of the road , and it being about 25-30 miles away with no mot on the golf would not be good .
How about a second hand relay and see if it works an if so get my but up to vw asap !

i went to get one yesterdayfrom vws, and they wanted 40 quid for one. Luckily, there was a gsf around the corner! :smiley:

Will definitely be a relay or the crank sensor. It doesn't matter if it looks new, I had one fail in 3 days...the cheap ones are absolute crap.

update .
i have had to order a relay from Volksbits due to not being able to get one local or from Vw .
Also ....
Had to take the car back to garage for tyres and an mot restest ,
On cold start it was a little hesitant between 1k and 2k revs soon cleared after a minute ,drove to garage fine .
But on the way home again the probleem started after aprox 15 mins of driving (very close to home) at the turning to go into my road i stoped and so did the fecking engine !
I wiggled the relay no joy took out tpped it no joy , under bonnet wiggled ht leads and earth strap to coil pack , nothing . it wouldnt start for a few minutes the boom running near eenough sweet as .
Got it on my driveway and it sounded like a misfire , so i removed each ht lead as per norm and as it should be pulled each one out and it got worse .so no prolemo there. after say 5 mins of trying to identify the fault the engine decided to run fine again sweet as fook . :/
Just as a precaution i cleaned out the oil breather hoses , neither were block but a little gunky ,made no change for the issue .
Im now letting the engine cool down to see what it is like on a cold start again .
i Believe there maybe more to this than the relay by the sounds of things but due to the excessive clicking im replacing to erradicate that problem all together
As allways many thanks in advance

contacted the previous owner , it waas replace the day i got the car for a cheap one due to it cutting out but no real hesitation , was cuttin out on idle too .
At the moment cutting out on idle on the driveway is no issue at all seems to be fine .
-
Hi bud,had similar problems with my 8v.Cutting out randomly after about 15 minutes driving.Put new fuel pump relay in and so far been ok.Fuel pump relay aint supposed to click and when they get warm the contacts inside can seperate,causing the cut out/stalling.I also changed ECU relay for good measure.

Try the relays first as they're cheap, if that doesn't fix it try the crank sensor. Just make sure you get VW or an OE quality aftermarket one. The Premium one from Eurocarparts on my car has been fine, the cheaper failed in 3 days, got my money back on it though!

I got my crank sensor from GSF, Still going strong :cool:

I'd go for the Delphi one or if you can afford it a Bosch one,but they will knock you back about £100. :shocked:
-
The £55 one is the one you want! Can't remember what brand it is but mine has been fine.
-
Any luck mate?
-
Not just yet , im waiting for a relay to come from Volksbits in the post , either monday or tuesday . There parts are very reasonably priced on ebay.
Then ill drive the car untill it happens and replace and see results :)
-
I still have this problem ! .
Replaced fuel pump relay and taxed car today , started fine .
Drove about for say 15-20mins boom !!
Bogging out backfiring at 2500rpm ish . Somtimes at 3k .
Found a suitable place to pull over and i have a vid to explain what happened .
After this vid i walked to a shop got meself a drink and more smokes ! I got back to the car exactly 2mims later , temp gauge was still in centre 90deg .Turned key it was sweet as fook :/ so drove the say 5 min remainder home if that ! .
If im right in thinking this could be a temperature switch/sensor still telling the engine its cold and in essence giving more fuel when not needed ! ??
Video is just uploading via photobucket will post link asap !
-
Ecu Relay they where a known issue with vw if not the relay then go with crank sensor
-
i dont mean to question you as ive heard thos are very common issues with the mk3 but, what about the fact its ok after 20 minutes ? would this factor into those issues ?
Many Thanks James

Crank sensor can fail when it gets warm, won't restart, leave 10 minutes to cool, then it will be fine, sometimes for minutes, sometimes days before it cuts out again. Replace it with an OE one!
-
And fuel relay is clicking on/off because the ECU keeps cutting out the fuel pump when it loses the crank sensor signal.
-
If its not your crank sensor I will eat my hat.
-
im still in contact with the person i got the car off and he sent me this link wich is what he bought and fitted from ebay just before i bought the fooker .
http://www.ebay.co.uk/itm/400419490696?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
What you are saying makes perfect sense sir , this cheap and nasty sensor has probably gone duff in a matter of minutes !
-

Listen to what this good man is saying.
My car had exaclty the same symptoms, it was crankshaft sensor. after looking at video, i'm 110% sure it is that :wink:

It does actually say Delphi on left hand side of screen under where you put your cars reg no. :smiley:.Like i've said before if you can afford a Bosch one then get that,but as your on a budget this should be ok.
-
Ahhh yess i did not see that ,Thanks .
My budget is rather low , trying to save the pennys and not alot of work due to weather . There is a cheaper sensor on Ecp but has no brand name in the box like the Delphi. But i shall plunge and get the best i can afford which is the Delphi .
Thanks for help and i shall return with results once i have fitted new sensor . Thanks
-
I have the Delphi one, its fine. Ecp have a sale on this weekend so now would be a good time to buy!
