My clutch has started to slip a little when i put the foot down (smartly) in 3/4/5 and even 6th (sometimes).

I have a 53 plate 130PD with a DMS map (RR figs 170 bhp, 285lbs).

I've switched back to the stock map and no slippy. A bit peed off as i thought the PD clutches were rated to 300 lbs...

How much is an uprated clutch and any recommendations?

Any other ideas?

I've just had a Sachs clutch fitted, will do a little review on it when I get a chance. Can also give you the details too.

Cheers Nik. Appreciated. Expensive?

E: *slaps head* I completely forgot about this forum. I'll do a bit of research...[:O]

fatbob, have you tried a 'clutch burnout' [?]

apparently it is meant to help the cause. I have to say i am a little dubious - not that it works, but that it doesn't do more damage.

No I haven't - perhaps you could explain the 'how to' and the benefits...please?

As just posted by me in another thread Phil;

Sachs manufacture the OEM VW parts and also uprated clutches which owners of tuned cars would do well to consider, especially if they are experiencing clutch slip under high torque loads. So I wouldn't worry about quality, its the same manufacturer.

NikB has just fitted the uprated Sachs clutch to his highly tuned PD150 with very positive feedback. I have ordered the same part, as has Micky.

The uprated clutches can be ordered online from Triple Eight the BTCC team who act as the UK distributor for ZF Sachs Race Engineering and the Sachs Performance range of road car dampers and clutches.

If going for un uprated clutch only consider the organic plate material - the sintered plate is suitable for race applications only.

I havent done it myself, but it apparently in some instances gets rid of the clutch slip.

Here are the 'how to' comments I have collected:

do this little test....

at 60mph push the clutch in 1/3rd to 1/2 way push the throttle down so the needle goes up to the red zone and release the clutch so the revs drop back again whilst releasing the throttle and maintain 60mph again. give it a few hard accel in 4-5-6 gear and if it slips again let it do it a couple of times and then it should not slip anymore!!!!!

Worked for me.. I read this trick on here somewhere!

I guess it's the extra torque as we both had approx 230lbs/ft and after remap we had again approx 300lbs/ft.

Even after 3 months my clutch still doesn't slip!

Yeah, defo clutch burn out to stop slipping.

I did mine at standstill: handbrake on, hold revs in mid range, slowly let clutch out, as it starts to load up engine increase throttle, if you start to move back off throttle or clutch.

ONLY do this for 10/15 secs etc. The car will stink for a few minutes after, indeed a good reminder that you have "de-glazed" the clutch pads adequately with be the accrid/fishy smell!

Did this 3 or 4 mo ago, hasn't slipped since.

Hi...

I am in exactly the same situation (TDI PD 100PS) has it revo'ed and exactly as you said, put it back to stock no problem...

I am megga unhappy! Reading here it seems it is my clutch not being able to handle the increase in torque (only 29k since new , first owner)

I'm thinking it's just your 'luck'. I'm still running a stock map, as i don't have ?600+ to swap a clutch out!

Annoying though!
