got my car back from dealer after suspension issue was sorted.
now in 3rd and 4th gear the revs are dropping when accelerating, its strange, revving freely then you can hear it dip and then continue.
any ideas ? MAF sensor perhaps ?

C5 hdi - revs dropping...
hi all,
got my car back from dealer after suspension issue was sorted.
now in 3rd and 4th gear the revs are dropping when accelerating, its strange, revving freely then you can hear it dip and then continue.
any ideas ? MAF sensor perhaps ?

Unless the car has an auto gearbox, surely the revs can't alter without the road speed also altering.
As I get older I think a lot about the hereafter - I go into a room and then wonder what I'm here after.

Slipping clutch?
My first few cars (the kind that cost £100-£200), in the higher gears when accelerating the revs would climb faster than usual for the gear, then drop down. I lived with them till they dies of something else.
I don't know much about cars but maybe oil has got into the clutch when the suspension was fixed? Or maybe its just on its way out.

Re: C5 hdi - revs dropping...
It wouldn't be the clutch as it would slip and the revs would rise.
Does your car have ESP/ASR? Try disabling it if it has.
BTW, I'm assuming that the car physically slows down when the revs drop and it's not like accelerating with an auto box during the change up in gear.
This may be something that the ECU is doing wherebye it's overriding your accelerator pedal and reducing power. The only time this normally happens for me is when I'm driving on snow or ice.hdi_man wrote:now in 3rd and 4th gear the revs are dropping when accelerating, its strange, revving freely then you can hear it dip and then continue.

Could it be the engine slipping into limp mode?
I used to drive a lot of Vauxhalls and if it threw up the Engine Management Light, it'd stop revving at 4,400 RPM. It wasn't as smooth as the engine's 6,500 RPM limit, it was quite noticable, it'd throw it down to 3800 and then allow it to accelerate again. Apart from that though, there was no noticable lack in power, only that you were limited.
