Here's the scenario: I depress the clutch at 2000+ rpm, foot off the accelerator and the engine sticks at 1500 rpm for probably 5+ seconds.
I've had the car checked thoroughly for any air leaks, I've had the throttle body cleaned and a new PCV fitted, but I'm still getting this problem. It seems to be exaggerated when the car has been ran for a while, so the oil etc is up to temperature.
VW are supposed to have fixed this and they'll be getting a call first thing on Monday, I was just wondering if anyone had any other suggestions?
-
Scanned with VCDS?
Would be my next stop.

Well I imagine VW will do this, it wouldn't mean anything to me.
Is there any chance this could be caused by bad spark plugs, or incorrectly fitted coil packs? Or a dirty MAF?
Car seems to be running perfectly otherwise, though I haven't really given it full beans since I got it back on Thursday.
-
Bump bump bump!
Any ideas guys? Before VW bum me again tomorrow...
-
have you tried unpugging the maf. The car will still run without it. I would have pointed to faulty pcv but you say this has been remedied, Other than that try and speak to someone with vcds
-
Well I'm now in a position where VW have no idea what is wrong with the car. As it only happens from time to time I will persevere with it, but really I have no idea where to turn next :sad1:
-
Do you have someone close by with VCDS?
-
Well they've had it hooked up to VCDS and have got real-time data from test drives etc. but it's not throwing up any fault codes so they've little to go off, other than that they've experienced it revving up when stationary. They've had the senior technician working on it and he's stumped.
-
Problem referred to VW UK. They've given me a Scirocco until it's fixed, so life could be worse.
-
That sounds like a result for the time being Andrew. :happy2:
-
So unbelievably VW have pretty much given up on this now. I'm still very eager to get it fixed, if only so I can move the car on. I don't think my confidence in the car will be restored, or VW for that matter.
-
It's gets worse. VW Huddersfield have been sending reports to VW UK in an attempt to diagnose the problem. The latest question back from VW UK was to check the spec of the tyres! Really, how on earth would the tyres effect the car revving at idle, and the engine management light coming on?!
-
Sounds like they are clutching at straws to me......

Sounds like diversion tactics on behalf of the dealer to me.
My worry is that if it can't be fixed, where does it leave me? With a car that is unsaleable?
-
bring it over one day mate sounds very odd.Get a list of everything vw have checked too so your not doing things twice :smiley:

Cheers Mat, that's a very kind offer. I've put a lot of pressure on them to sort it and I think they're aware I'm not about to rollover and accept that nothing can be done. I'm also holding on to the thought they might be to embarrassed to admit defeat, but who knows!
I did wonder, although they have cleaned the throttle body, whether they had properly cleaned the butterfly flap on it. Could it be that that is sticking and sometimes causing the revs to stop falling?
-
could be but it can be moved by hand i am sure of it but they could start the engine and watch the flap to see if its doing its job.does the car drive fine i.e. when driving do the revs come back down smooth or is it just an idle thing ?
-
It varies to be honest. The revs never fall without pausing at around 1500rpm, then falling very slowly. Generally the idle rpm from cold will be 700 - 800rpm, but after driving for 10 minutes or so the idle settles at 1000rpm. I thought that a warm engine would result in a lower idle. Sometimes when sat at idle the revs will start to rise slightly, and sometimes if I rev the engine up to 2500 - 3000rpm, it will fall to 1500rpm, then flick up a few hundred rpm. Sometimes when coming to a quick stop the revs will stick at 2000rpm and literally hang there for 10 seconds, foot off the accelerator and firmly on the clutch.
The car drives absolutely fine. I removed the MAF and didn't see any noticeable difference. It's had a new PCV and breather pipe, a new throttle valve, DV, charcoal canister, N80 valve, coil packs and some other hose going into the throttle body. Only thing I'm aware that needs changing is the spark plugs.
I'm tempted to get some diagnostic runs on a dyno because it's getting to the point where I've forgot how it should drive!
-
Well I received some quite unexpected news today. VW claim to have reached a conclusion. Their word, not mine. Apparently they have identified an air leak between two pipes going into the intercooler, where a rubber hose meets a metal one they said. They have said they will cover the diagnosis and labour time, leaving me to pay £120 for the parts.
I'm amazed that this saga has gone on for almost 5 months, and I'm rather skeptical that I'll finally be able to put it behind me. Still can't help but get excited about getting my GTI back though!
-
Good news (I think)! Not surprised that what they have found will cost you, but if it does sort the problem out then I suppose its a small price to pay! :happy2:
-
I've made it very clear to them that I want them to be 110% sure it is fixed before giving me the car back and that this is the last time I spend money on a supposed fix. Truth be told, I never expected them to offer to cover the labour, so that is a bonus. I've had a few very nice cars while it's been in too (though I can't wait to offload the EOS!).
I'm off to spend some money on some detailing products so I can give it some love and get them sexy wheels back on it!

Had this exact same problem on my vw and still do have it but occurs much less often after I found a loose vacuum hose and replaced rocker cover gasket.
-
So it is imposible to fix
I must find someone with smoke machine to test vacuum leaks
-
You can get that same symptom from a bad clutch pedal switch.
