I've bought a 2.0 mk3 Ghia X TDCI 130 6 speed , new Clutch/DMF in January (sigh!).
Just had a full service a few weeks ago too.
The clutch seems OK, the car (and diesel in general) is new to me so I'm not 100% sure about the power profile. Anyway...
Was returning from M25 J5 to M25 J4. This is slightly uphill.
Performance was dire on the incline.
At 70mph - car did not want to accelerate with full gas in 5th gear.
Dropped to 4th gear - it nudged up to 75 - full throttle - revs seemed stable - lots of smoke out exhaust. But no real pick up - getting passed by lots of other cars of all sizes and shapes.
The outward journey seemed fine on flats and declines - a comfortable 90 - not a usual habit but just getting a feel for new car.
Also back on a dual carriageway - at one point was doing 40mph - dropped to 3rd to accelerate - lots of smoke.
No burning smells - but my sense of smell is not brilliant - just normal!
So is this a clutch issue still?
I just took it back to the garage that did the clutch? They are looking at it and said it might be clutch or catalytic converter?
Town driving seems OK.
Had the same myself it ended up being the diesel pump in the end after changing allsorts of things car runs perfect now although with all the smoke i would defo check the boost pipe first
