Sticky Throttle Problems
« on: January 28, 2012, 07:22:43 pm »
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.

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:

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.

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 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?
