Title: Clutch slipping
Post by: ScottA on 12 May 2012, 22:40
Hi all,

Well I'm not having the best of luck with my car... what with the water pump problems and minor issues that have been fixed under warranty. It's got 2900ish miles on the clock now, had it mapped when it hit 1000, and first noticed the clutch slipping today at approx ~2600 miles. I've done 350 miles today, the car's been fully loaded with lots of camping equipment, clothes, scuba diving equipment and so on so very heavy and it started slipping really bad. I've unloaded all of the crap and been out again and it seems better - not slipping as much, if at all, very paranoid about it now though but it was slipping very bad when fully loaded.

Gutted after so fewmiles but something I've always known could happen but hoped never would after a map.

Quite a few fault codes showing up at the mo so saved a copy, cleared them all and will see what shows up tomorrow after a drive. The car spent quite a bit of time on a dyno perfecting the map which probably hasn't helped.

 :embarassed:

Just how hard do you drive it!?? :huh: :undecided:

Not a direct comparison but my clutch has survived over 16000 miles (nearly 47k in total) and has had its fair share of abuse on Carbons dyno

To me your clutch shoulndt be slipping unless its a very aggressive map or you are loading the car up in too high a gear  :undecided: or you have a mechanical issue with it...

Am on Revo stage 2 with 360 lb/ft of torque with no issues. Either your driving your car like you stole it or your just one unlucky guy! See it as an opportunity to stick in an uprated clutch  :cool:

Feel for you and hope you can get it sorted quickly

Is this the reason why you wanted to use someone else's car?

a leaking slave cylinder can make your clutch slip. could it be this?

Was suffering a noise from the clutch. Car went into the dealer on Wednesday and got the car back on Friday.
New clutch was fitted and was told a lot of clutches are being fitted to GTI's so maybe a problem there.
Service was great courtesy car provided while mine had been vacuumed and washed when I picked the GTI up.

Anyone know if the mk6 gearbox has a torque limit stamped on it like the mk5 had.

Mk6 manual suffers from dual mass flywheel issues as did the mk5 so I'm told.

I did about 30,000 miles on the stock clutch on my A3 2.0 TDI that was mapped and didn't have a single problem with the clutch. I use the power but I wouldn't say I drive it really hard. Here's a graph, I wouldn't say it's really aggressive

Many of the miles on my GTI (which was at 2950 today) are motorway/A roads. Some are town. Very little in traffic though....

Oh dear mate, more trouble for ya :sad:

Haha I know mate, makes me laugh tbh  :grin: I hate cars !!!  :grin: :grin: doesn't help that I'm 350 miles from home at the mo and the clutch is slipping even without a 2 tons of crap in the car now so gonna be an eventful week I think!

Ahhh that's interesting! Yeah may end up with an uprated clutch but going to see if I can take it to some local dealers here in Cornwall where I'm staying until Saturday/Sunday to see if they have any loan cars available etc and get them to look at it.

Feel for you and hope you can get it sorted quickly

Thanks. Nah that was a joke about Forge's request to borrow someones GTI for 2 weeks for development  :grin:

Interesting..... thanks.... any other symptoms or just clutch slip? I did notice the clutch pedal feels like it "sticks" very, very slightly sometimes, just before it engages. It's hard to describe but it's ever so slight. I noticed it 2 weeks ago (probably 700-800 miles ago) for the first time and it hasn't got any worse.

Glad you got it fixed!  :smiley:

I'm gonna call the dealers around here as I'm about 350 miles away from home at the moment and see what they say. Hopefully one of them has a car available and I can take mine in and get them to have a look.  :cry:

Thanks everyone  :smiley:

with a leaking slave will feel judder when pulling away sometimes as the clutch isn't re-engaging smoothly due to hydraulic pressure leaking

if fluid gets on the flywheel or clutch plate it will slip.

my vans release bearing was buggered but if i pumped the clutch a few times before starting the engine i could get around it.

Funny you mention this as the GTI seems really jerky (sometimes) when pulling off but I've just put it down to my poor clutch control  :grin:

Although I drive a lot of hire cars through work and never have a problem and I've never had a problem with my previous cars

It hasn't slipped for a while now, in fact the day after posting this thread I took it to a local dealer in Cornwall, it slipped on the way there but no matter how we both drove it, it didn't slip with the tech in the car. He basically said it was probably wheel spin  :rolleyes:

It's slipped maybe once or twice since then, even with all the cr@p back in the car today on the way home, it didn't slip... or if it did, not as noticeable as when it first started. There's also been no "clutch smell" apart from one occasion, which was strange as it wasn't slipping! I think it may have been the car in front as we were going up a MASSIVE hill! I would expect some kind of smell when it does ??? as I mean it's literally going from 3000rpm to 4000-5000rpm without accelerating the car - that's a lot of "slip"

The clutch pedal also feels like it sticks sometimes when coming back up. I think I mentioned this before in a previous post. Sometimes it doesn't do it, other times very slightly, sometimes quite bad, altho I've heard some people have problems with their clutch pedal doesn't come back up at all and it's certainly nothing like that, you can just feel it sometimes

Thanks for the help. It's booked into VW on 29th although I suspect I am away with work then so may need to reschedule. I'm glad it's stopped for now though as at one point I did think I'd end up breaking down!

I know what you mean about it being jerky, mine does that too but like you i've always put it down to my poor clutch control! :embarassed:

i find the clutch on the gti is very hard to modulate. its basically in or out i find and the pedal is so soft and the biting point so soft its hard to judge where the clutch is. trying to pull away smoothly just leaves you sitting there.

there is an ECS tuning part for the mk5 which reduces this but its not available for the mk6 yet - its a bleed block/cylinder connector which is metal instead of plastic and is meant to improve pedal feel.



the main thing i dislike about the GTI other than the squeaks and rattles are the poor pedal feel. all 3 pedals are so vague its like a video game not a car.

how is your brake fluid level? if its low it could point to a weeping slave cylinder

My sister's other half was a master tech at Audi..... He reckons the driving hard with the paddles constantly causes alot of mechanical issue with the DSG clutch. I never use my paddles tbo. I can't get to grip with the bloody things anyway ( I'm the same on the playstation  :smiley:)
