Had new fuel filter . fitter connected his laptop. .
Yet engine malfunction won’t disappear his computer says all fine no errors message won’t go away
Computer did say cruise control error he tried reset it…
Warning won’t go away.
Been driving it all day today cruise
Etc works fine drives okAny one have any ideas?
Also been told by workshop ok to drive. Been driving it all seems fine .
And What’s the score with vosa if get stopped and see the warning
If hes not using a Davie but some generic test kit, tbh they arent a lot of cop unless its a real obvious fault.
One thing to check is after a short time with the engine running from cold ( 2/3 minutes), switch it off and release the header tnak cap to see if its pressurising, there have heen lots of issues with this over the last year, also crankcase ventilation modules.
