Fine people,

I just got the car back from the diesel center.

The car is drives well however, I noticed...

it is reving somehow higher than before. Accelerator cable is not tight.
RPMs is sitting between 5000 and 10000 RPMs while idle...

What is the correct idle rpms?

The knock is louder and sharper than before and does not go away.
The car is running on pure diesel.

I took the car back to the diesel center and they reckon the idle can be lowered down but I am not sure what is the correct rpms.

Can someone advise on that please?

Regards
