Hi peeps,
This started a couple of weeks ago, the car starts fine, ticks over fine, drives away ok untill it reaches 30 to 40 mph then slows quickly down & shows the `engine system fault` if i pull over & stop then it will pull off ok again untill i reach speed or accelerate hard then it plays up again it just does the same everytime. In 2 years its never missed a beat now this . Had a breakdown guy out, plugged his diagnostic laptop in, no fault codes showing.
Any ideas to this would be most appreciated !!

Intercooler hose split or delaminated, fuel filter reqs renewal or turbo maybe. Lots more info on the D3 site which may help you as well.

Sorted "touch wood", contaminated diesel !!
