Worn Clutch?

I think my clutch is on its way out

Under heavy acceleration in 5th (from about 55mph) the car seems to judder then pick up speed. You can see the gear stick wobbling as it judders.

When releasing the clutch in 1st it feels like theres something grinding, doesnt feel as smooth as it used to.

I tried setting off in 4th and I was able to crawl for a metre or so before the car stalled.

Are these signs that the clutch is on its way out? I had the original clutch replaced at 51k with an OEM (Sachs) one and im currently on 77k. the car has been remapped since and I suspect that the extra torque is taking its toll on the clutch.

If the clutch is on its way out, can anyone recommend any uprated clutches or will the 2.0TDi (170) clutch fit onto a 1.9TDi?

TIA

Anyone?

Ouch, sounds expensive! The car got rear ended the other day (the Ka that hit me didn't come off too well), so I'm thinking of getting the accident damage repaired and get shot of it. It's a shame really because the car is immaculate! I found the stock map made the car sluggish and lacked power when overtaking, time for a bigger engine and possibly an auto box...

£163 for the Sachs Clutch Kit
£330 for the DMF
