Bought a N-reg VW Golf 2 litre Gti 8V last weekend cheap...
It has a few issues, main problem is the rev limiter is at 3500rpm... I know this aint the right forum for it, but if anyone can help me with a Golf site that might be able to help me with this problem, would be much appreciated... Or if anyone on here has come across the same problem

I've changed the dizzy, rotor arm, dizzy cap and done the timing belt just to make sure the timimg marks are spot on... and still it hits the limiter at 3.5K...

 

cat clogged up? breather ok?

 

i had this on my colour concept and all it was ,was some idiot when they replaced the dizzy (known for being troublesome on these)
got the rotor arm alignment out of place ..
so in effect at tdc on the crank it was nowere(rotor arm) nr pointing to no 1 cylinder on the cap
they have them helical gear drive on the dizzy drive so is easy to get wrong try it and see

 

Cat/ breathers ok... Seems electrical fault... deffo limited to 3.5K...

I've done the belt and timed it all up perfect... all the marks on the belt side are perfect, and the dizzy cap lines up perfect with the mark on the dizzy base...?
Only other thing I think it could be is the wiring to the hall sensor on the dizzy...

 

crank/cam position sensor

same thing happens on vectras,pretty common for it

my birds car was doing the same thing,no power etc but wasnt the crank sensor,it was the centre section baffles had collapsed and blocked the backbox,hers is a p plate 2.0 8 v too

hope one of those helps

 

The 8v's dont have a cam sensor do they?
If it was crank sensor surely it wouldn't start at all??? It runs perfect bar not reving over 3.5K...

Exhaust blocked??? Can't see it but could give it ago...

 

The run around...

 

I had the 16v version for about 6months, it was decked on Bilsteins and hard enough to knock a few fillings out over pot holes but handled well and went well, only got rid because the box was buggered, 1st,2nd and reverse wouldnt always go in, good cars though

 

bttt Anyone help?

 

ignition coil/amp problem iirc was quite common on these!

 

are those merc wheels i cant help you with the prob mate, but at least the car looks good

 

Would this cause the fault i'm having atm???
Thought if the coil was breaking down it would be a intermittent problem or just not start full stop???
Possibly not giving full power hence in limp mode as such???
Anymore ideas out there???
VW Mechanics that have seen this fault before would be good???

Wheels are Merc wheels yes... 16's, although not sure what Merc there off, there old though, fitted with adaptors on my hubs... Think they suit it tbh, just want a fresh bit of paint on them... Dropped 60mm although i'm very tempted to get the grinder out on the new springs lol

 

i had one m reg only used to do it when tank was below 1/4 would cut out too every now & again , i thought it was fuel pump , mine only 60k on dragon green , loved that car looked mint even tho it was a 5 door . lowered etc .

sounds daft but it had a fuel filter put on wrong way ?

 

have you pluged it in to vag com? guessing what it is will take time,checking codes first then go to the mechanicals.

 

Since only owning it for a week, I've changed the wheels ( tires were down to the wire on the standard GTi wheels or that was my excuse )
, 2 window regs, engine wise, oil + filter, fuel filter ( fitted the right way ), plugs, leads, dizzy cap, rotor arm, air filter...
2nd hand dizzy, and finally a timing belt kit...
It went on a mates computer ( MOT station I use ) which come up with hall sensor...
I'm gonna try get it on vag-com towards the end of the week...

 

Told you mate bring into work. I will happily put it on the proper VAS machine for you

IIRC on them if you do a check with the engine not running it always brings up G40 hall sender no signal fault. Could well be a blocked cat or maybe just the basic settings.

Give me a txt one night before you come and we can sort something out.

Mart

 

ive got a k plate one of these in red about to be scrapped though

 

Will do...

 

I've changed the dizzy,


you have answered your own Q there

when you change dizzy did you put it back in the same place

becous the dizzy needs setting with the computer plug in
cous the timing is out the ecu wont let it rev

 

I bought the car knowing it wouldn't rev past 3500rpm...
I changed the dizzy to try and cure it...
Still won't rev past 3500rpm, just banging on the rev limiter...
I've also fitted a new timing belt and its timed to perfection... still the same I do have a idea on what i'm doing you know
Took xrt mart out in it last night... its hopefully going into his work shortly to go on vag-com...
I'm sure i'll get there with it... Its worth asking about though as it is a strange one...

 

ECu is in limp home mode...

Get a Vagcom tester on it.

 

Right... update on the Golf GTi... Its been on Vag-com today, and been given a clean bill of health, no faults whatsoever... The rev limit is actually kicking in at 5000rpm, the rev count inside the car is giving a false reading... although I think the rev limit is alittle on the low side...
Been told to change the coil, this should sort my rev count problem out fingers cross... and increase the rev limit up to the 6000rpm mark

 

Cheers XRT -Mart for your time...

 

Sorry i didnt get back intouch Chris. Had a mad couple of weeks.

Lemme know when u change the coil and what happens.

Lookin good btw. I like the wheels.

Colour Concept trims rock!

 

If you like yellow I suppose...

 

My guts are saying.Get someone to set the ignition timing, valve timing and then reset the Basic Settings on a VAS 1551 or 5051 or 5052. (01 (engine)-04(basic settings)-000(Value) IIRC)

Could be the coil, but Id be surprised. They tend to fail completley. No spark so no run. Possibly the ECU...

Ignore the Hall Sender fault. That only occurs if you check the fault memory when the engines not running.

 

These things are nortorious for electrical faults try ya fuel pump relays under dash, failing that cud be ya mass air flow meter very common problem on the 8v's usually makes them cut out wen they hit running temperature. cant see it being the coil wud either just cut out or not start even tho this is also a common fault on them i changed loads of stuff on my old 8v and was the air flow meter in the end failing that get a diagnostics don it shud find whats up straight away

 

The car has no faults, its been in Skoda on vag-com... everything has been given a clean bill of health...
Rev count is giving a false reading on higher rpm... Been told this takes its signal from the coil, I have use of a couple of coils so its worth a try, 1 to fix the rev count, 2 to raise the rev limit from 5000rpm...
Eva way, 5000rpm aint the end of the world, I just like things to be right...
I fitted the cambelt last weekend, its timed up perfect, it was doing this before hand... so another possible cause illiminated

 

I like that aot..........get it slammed on the floor...give it the VW euro look and it will be superb

 

Im telling you to get the basic settings reset. Im telling you because years ago I had the same problem (I was an aprrentice FFS LOL) Id fitted a cambelt to a 3a Passat 2.0 8v. (same engine) It ran fine but wouldnt rev up past 5K or so. Assuming the Valve timing is OK. Get the ignition timing set spot on (6 degrees +/-1 IIRC) then get the equipment to teach the ECU the "New" settings.

All the other faults tend to be of the wont start variety. so Relays and coils and even crank position sender. ECU isnt unknkown to fail in a bizarre way, but this isnt likely.
