Diesel Juddering Under Acceleration Uphill

[Marty Funkhouser]

Like the title says - its a 2005 Volvo v50 diesel. Perfectly fine accelerating on level road but when I try to accelerate uphill its almost like the engine is cutting out then coming back to life rapidly.

Any ideas?

TIA

Dual mass flywheel on it's way out I reckon.

I know mine kind of does what you're describing and mine has a really warn clutch, It could be starting to slip?

[Chrisw666]

Which engine is it?

[Marty Funkhouser]

All I know is its a 2 litre diesel. It runs fine in every other condition.

[Chrisw666]

Possibly the DMF or a Clutch issue then. The engine is shared with a number of Fords that have similar flaws.

[Steffan]

Could be several things but IMHO the two comments pointing to the clutch are probably right. Failing uphill is classic sign of clutch trouble.

Otherwise engine management system but I favour clutch.

Cheers chaps - taking it to a reiable mechanic tomorrow.

Well it turned out to be a fault with the fuel filter seal - all fixed!

[Superhoop]

I'm sorry, but I'm not having this... It can't possibly be a faulty filter seal, how dare you dispell the myth that diesels can also have simple, cheap to fix faults too

It's a diesel, so it has to be a DMF fault, which will cost you at least a grand, and probably also needs 4 injectors at at least another grand... oh and don't forget the EGR valve fault

I say this, as every thread I read on PH that even dares to mention diesels with a fault are always a combination of both of these - that's why no PHer would ever buy a car powered by the fuel of the devil

You sir are plainly an idiot! Its obviously the DPF!

I'd live with it if it is to cost thousands. Read that a fuel injector being out could be cause.
