Hi All,
My 2002 TD4 developed a fault the other day which it has decided to keep...
When driving at constant speeds (i.e. on a motorway) randomly it starts to run roughly, if I accelerate hard it pulls smoothly and as quickly as normal but after a while once at constant speed it randomly reverts to rough running.
Then last night in traffic on the M25 it started doing it at idle/low revs, clear traffic and the issue vanished - a bit later at 70 ish it started again.
Has not repeated the rough running at idle since and always starts perfectly.
100 miles before this first happened I filled up with fuel from Sainsburys and after ~ 450 miles I filled up again, this time at ESSO. After the issues on the M25 I bought a bottle of injector cleaner and have added that to the tank - however I have only driven 20 miles since that so not enough time to do anything I suspect.
For some reason I couldn't log on here yesterday so I looked elsewhere and hence deduced dirty fuel/injector - anything else I have missed - moth of the rough running probllems on here tend to be either poor startign/idle or lack of power - which I don't think is the main issue.
Car has Synergy 2 fitted but Bosch MAF.
Cheers!
