Hopefully someone on here can offer some suggestions, as I've tried everything I can think of:
I had two issues on the way to work earlier this week. The first was the unexpected illumination of the skid and ESP lights on the dash, the second was a momentary loss of power and a really rough idle when stopped at the lights. The engine was warm but the weather cold.
The first issue appears to have cleared and I'm assuming a glitch/ice in one of the speed sensors. I'm not worried too much about that unless it recurs.
The second is still very much a problem. I have so far:
Reset the ECU - no change
Cleaned the MAF
Replaced the air filter and fuel filter
Replaced the SCV and reset the ECU - immediate improvement in idle but still frequent loss of power (occasional, not constant, inability to rev beyond 2k or 2k5 revs)
Put premium diesel and injector cleaner into tank (was about 1/3, now about 3/4)
(the SCV bought from PF Jones having given them my part number so presumably correct - no fault codes logged by the ECU since last reset)
I still have the same issues. It is possible that they are more apparent when cold, hard to say as it doesn't happen all the time and seems unrelated to selected gear or driving conditions (so I'm thinking not neutral position switch symptoms, although I think this is D40 only anyway).
My best guess now is that perhaps I had some bad diesel. I did fill up at an economy station several days ago but would have done 2/3 tank with absolutely no issues. But water, now ice in the fuel perhaps? Could this have blocked the fuel filter/SCV?
Is there anything I've missed? Air in the fuel lines (the primer bulb appears to be hard)? No smoke when it loses power so fuel related and not turbo, for example? Anyone else been having issues due to the temperature?
All/any advice and suggestions gratefully received. I've done about 20 miles since changing the fuel filter in test drives - possibly enough for bad fuel still to be in the fuel filter?
