Hi guys, any help would be appreciated. I just drove 220 miles yesterday in my 07 3.6tdv8 fine no problems. Today I go for a short drive and the engine light is on the car for the next 10 mins is very judder dry at low speeds I put my foot down and was still judderey. It seemed ok ish after 10 mins light is still on. Don't have access to a fault reader as I am at my folks I need to drive another 200 miles on Christmas Day any ideas? I am going to take it out again just now to see what happens. Thanks in advance

When the engine light can on did the car go into limp mode.  2020 Porsche Panamera Turbo Hybrid (V FAST)
2017 Range Rover Autobiography 5.0 V8
2018 JCW Mini Cooper
2018 Skoda VRS

It did not say anything I pressed the dash button and it said check system ok - I think it was not in limp home mode does it say anything like that?

Took it out again - seems to be when I ever I put my foot to the floor or try to accelerate more than ver gradual it stutters maybe a fuel filter thing? I just had it serviced from or Edinburgh last month so a bit suprised will try to get t to dealer tomorrow check out

Maybe injectors

Thanks guys - yep if I accelerate slowly from still or any speed it seems fine maybe slightly judderey. From standing start flooring it judders a fair bit but has spells where it is smooth ish. Essentially though light acceleration much less judder

sounds like a fuel starvation problem due to blocked injectors or pump maybe....cheapest 1st port of call could be sticking some injector cleaner in the tank to see if that helps... ... - .- -.

Thanks guys I may take the trip from manc to London see how it goes...

defo try some injector or fuel system cleaner in a tank of fuel and go from there

Cool thanks-should I not be too worried about the engine light. It's still on but the car was going up and beyond 80 last night

How much fuel is in the tank? FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's
Mantec Sump Guard, Rigid Load liner, MY10 BT upgrade.

It's full put some Carlube diesel cleaner in around 3/4 then filled it up

Hmm. Id be more tempted to say a fuelling issue with the supply and not the delivery...

When was the fuel filter last changed?

Injectors on diesels tend to fail by leaking and slowly getting worse not failing to open properly but there is always the odd one i guess  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's
Mantec Sump Guard, Rigid Load liner, MY10 BT upgrade.

Well I had a service in Nov it was the 70000 5yr service I think it should of been changed then don't have documentation to hand -will driving it now be ok it should not make it worse its a motorway journey so maybe should clean it out - although the previous journey from Edinburgh was mainly motorway that's why I can't understand. Unless it was some cloggy bad diesel I was using vpower as well - went back to normal on this tank
