Mein Auto:
Could this be due to clutch?

I have a 2002 E39, and for a while I have beeen noticing the following:

The lower gears (1,2,3) do not respond to the acceleration very well. The rpm shoots up, but the speed does not. Though, the acceleration responds well when in 4th or 5th gear.

Could this be due to clutch slipping?

A slipping clutch would be indicated by the opposite. i.e. slipping in the higher gears and not slipping in the lower gears. something else is going on.

Interesting enough I have to agree with both sides of this.
But bottom line is this: amanual transmission that demonstrates an uncouple between engine speedand drive speed has a slipping clutch...Period.
Now for the cost discussion:
You can spend as much as you like.
Dual mass flywheel or single mass....The flywheel is xpensive. Lots of points exist regarding resurface DM or not. The clutch shop in Vegas replied to me that "Although the book says no, customer request has had them surface 20-30 with zero complaints/problems" cost $65-85.
Then you need a clutch kit. Low cost kits about $250. Upper cost kits $600-$800
I would be comfortable with a moderately driven kit in the $350 range added to the Flywheel Surfacing. But keep a keen eye toward adding other pieces such as pivots if found to be worn.
Now for time. Not sure of your DIY ability or work environment. Your vehicle will be apart for 2-3 days minimum. I would alot 8 hrs to disassemble, time to surface flywheel, and 8-10 hrs reassemble.
If in a shop environment, I would need to complete this job in 8 hrs.
