I assume you have a rev counter... if it's fed from the alternator, make
sure the connections are sound. Also (ideally) that it's the correct
The diesel pump has a governed maximum, yes. Free-revving should be about
4500 as standard, you can set it a touch higher, I think our 300 TDi is
revving to about 4700 or so.
Assuming that it does that (and check also that the throttle cable is not
