Hi guys,

In my manual disco 2, if I stay in a low gear (e.g. 3rd at around 2000-2500rpm) while climbing a steepish hill, the car will occasionally start jerking. However, as soon as I drop it into a higher gear it's absolutely fine except it feels like I'm labouring the engine and I don't get the adequate acceleration as a result of being in a higher gear.

Any ideas?

Cheers

I've just taken it on a dual carriageway and it seems to happen in any gear whenever it reaches 2500rpm. It doesn't want to go over 2500rpm either except when stationary. Does this suggest anything?
 
As I said, my personal suspect is that the arm itself is seized on the side of the turbo wastegate assembly. Which requires no new parts ;-)

Check that first if you havent yet!

If it turns out that the arm isnt seized but the modulator is dead, here's the info you need to change it:

But the arm seizing is quite likely, and an easy fix - move it about, lubricate it, and job done!
