Title: clutch slip?
Post by: luca on December 24, 2008, 04:32:56 pm
Just been on the motorway in the ed30 and had it in 6th gear at 50mph on the slip road. Instead of dropping a gear to get up to 70 i just put my foot down. I watched the rev needle jump from 3.5k rpm up to 4.5k as the boost kicked in and then drop to 3k rpm and the needle climbed normally.

What do you guys think?
Car is a 2008 ed30 with only 9400 miles on the clock. Car has never done a full bore standing start and is launched from 2k rpm at santa pod (its only done 7 runs)

Im thinking the icy roads and the car spinning its wheels trying to get the power down must have taken its toll :sad:

I would try to repeat the problem again, cant believe a clutch would go at 9,400.

if the cluch is slipping it would do it in all gears so i think it would have been crap on the road ie oil  :driver:

Agree with both the above posters tbh.

Sounds like road conditions allowed wheel slip

it does it in 5th and 6th. Tried it a few times on the way home.
Dont really notice it in the other gears. tyres havent got much tread but doubt they would spin up at 50 mph in 6th gear :confused:

going to take it out and run it on stock map now. Car is in for a service on the 30th but dont want vw anywhere near it for longer than it takes to do the oil change. Will probably take it to awesome or ads in preston and get them to look at it. If its a warranty job then i will take it to vw.

Just been out again and the car isnt doing it now  :laugh:
Must have been a long patch of oil or something on the motorway.
Will have a few more runs 2moro to make sure, didnt bother trying it on stock map as it wasnt slipping with the revo on.

just out of interest. how much is an oem clutch fitted compared to a sachs one?

clutch slip does normally occur in the higher gears, in the lower gears the wheels will spin taking the load away from the clutch, in the higher gears this isn't an option and with the high level of torque a remapped tfsi can produce the clutch is the weak link. I'm not saying your clutch is slipping Luca without seeing it first hand, I had the same issue on my mk1 S3, only slipping on the motorway in the higher gears and there wasn't much change fro 800quid for the uprated sachs unit I fitted. A few of the lads on AS-N with 8P S3's are having clutch issues because of the grip the quattro gives :smiley:

I shagged an Audi A3 TDI Quattro clutch in 11k miles after a remap and I'd agree with Gaz on the rest.

How much have you done to the car, I would put a lot of money on that clutch slipping.. my S3 did it as soon as it was running reasonable power

he's running Revo stg2, milltek TBE and a panel filter, seen 330ish bhp on Prosports rollers I think

clutch needed by the sounds of it,thats a third more power going through that clutch over and above standard. i guess the torque must be pretty high aswell. Uprated clutch needed.

Its not really the clutches fault IMO, the standard DMF is sh*t and because of the design causes the clutch to wear prematurely when running high torque..

Go with a new DMF and a sachs clutch kit, thats what I did on the S3, about £1400 fitted  :happy2:

Im not getting it at all now, if it does start slipping i would just put an oem one on the car as i will probably be swapping the car within this year. Usually keep my cars for aound 18 months then change them. Should be some nice cars coming out this year :smiley:. I want something with a bit more shout from the exhaut and a quick out of the box car :evilgrin:
No idea what i want yet but will probably be changng early winter time.
For now the car is fine and the only thing going on it is some new front boots next week and its in for its first service on monday.

The problem is if the clutch is slipping now and you dont put a new flywheel in it at the same time as replacing the clutch then your new clutch will make very little difference at all.. Especially if you put a standard clutch back in..

Most of the costs for the job are related to labour, so if you end up having to do it again (IMO highly likely) within the year, then its going to cost you way more than it would have if you have done it first time.. Plus the Sachs clutch kit is pretty much the same cost of an OEM unit..

I would say either try and get one on warranty or go the whole hog and you wont have to worry about it again..

thanks for the info jonny. the clutch isnt slipping at all now. will take it to ads when i get chance in the new year and get dave to give the car a full healthcheck and get some vag com done to see the car is running nice for santa pod.

With the cold weather be sure that you really give the car time to warm up, clutch and gearbox included..

Can take up to 20mins of driving for everything to come up to full temperature.. Sure you do anyways but worth baring in mind..

A cold clutch will slip pretty easily, and the engine will be making more boost than ever in these conditions, that combined with doing a pull into the spool of the turbo in 6th will give the clutch a really hard time..  :happy2:
