Has anybody found the real cure?

[AviatorEGHH]

You too please. I'd love to hear if the modified pipe helps you. Maybe mine is a dodgy pipe???

I was on a long drive yesterday and I think I had a progression of my issue.

I accelerated in 4th to high revs and then changed gear directly from 4th to 6th and drove for another 5 minutes or so in 6th at normal motorway speeds (if you know what I mean). When it came to changing down gears I pushed the clutch in, changed gear and on letting the clutch out, it actually got stuck half way up. I even had enough time to put my foot under the clutch, thinking I was going to have to help it the rest of the way up. It then actually came up fully by itself but this was the first time it has actually stuck halfway and stopped. Normally it just feels sticky coming up. It only did this once.

I still don't understand what could cause this mechanically??

[AviatorEGHH]

I have found something else out.

When this usually happens, it is after changing through gears on acceleration and then the clutch is sticky until the next push of the clutch which can be quite a while later. This next push of the clutch seems to clear the problem and all goes back to normal. I have found out that the problem occurs even when going into neutral. So actually the issue has nothing to do with gear engagement.

Sorry...just another symptom and no cure.

Come on, someone out there must understand the clutch system of the B7 RS4 or maybe someone can post the plans of the system or something.

Cheers.

I can't be bothered to read the entire thread.
You need a new fly wheel and clutch. It will cost you north of £2.5 to £3k

[AviatorEGHH]

Thanks for your input Covkiller.

Do you know what is actually wrong? I'm scared of paying £2.5-£3k for something which may not be cured if no one knows what they're fixing.

Thankfully I was actually quoted £1700ish if the flywheel is also required. All genuine parts.

Your clutch is basically worn out and so is the dual mass fly wheel; there is no return in the fly wheel, this combination is what causes the problem. If you can get under your car and turn the fly wheel clockwise, it will not return. When your new one is fitted then try it again, you will see it springs back an inch. The RS4 is a powerful car and the limit of the clutch and flywheel is approx. 70k miles.

You have a good price if that includes fitting. You may also need to loosen the front cross member to get the gear box out which may throw your tracking out, make your mechanic aware of this.

Covkiller, you are the only person who has given any hint of knowing what this issue is and I am very grateful for that.
I will pass on you comments to my mechanic who will do the work when the time comes.

Just one question...Is it normal to have this problem when the clutch is worn out but there is no clutch slip at all?

[Covkiller]

I had no clutch slip. I had a problem getting into gear. I had to switch my engine off and put into 1st when pulling off, as that's the only way it would go in.
I had my clutch changed at Listers Audi in Coventry where I have a great relationship with the lads there. They took the parts off and showed me what was wrong. Even the dual mass fly wheel issue, which is incidentally an exchange part. I had all slave cylinders, hoses etc changed too. These did not cause this issue but I had them changed anyway.

Really ??

So Ive managed a further 60k miles on the same clutch and flywheel (thats knackered) with 440ps ??

Glad youre not a mechanic bud lol

[Covkiller]

Blareider, you've done a 130K miles on the same clutch? Well done.

I've done about 60k miles on the same clutch and flywheel with this issue - which would be impossible if the clutch or flywheel being "knackered" was the root cause of the clutch pedal sticking down, as you suggested.

The previous bills I have for the car show no sign of a clutch swap though, which I too find highly unlikely but it was a 3 year old motorway muncher when I bought it in 2010 with 60k miles on it, so who knows. Been waiting for it to go pop for a few years now lol

Top tips:
1. Spend the money
2. Get your clutch fixed

Then come back to me and tell me I don't know what I'm talking about

[AviatorEGHH]

Guys, I just found this on YouTube. It may be of interest to anyone who knows what a correctly functioning pressure plate does in comparison.

Does anyone know what the guys means by "SAC" of the pressure plate? Otherwise he is describing and fixing exactly the problem we seem to have!
