motor control unit failure - please help
I wonder if anyone can offer suggestions to my rather ill timed problem..
On Friday I drove 300 miles to a friends wedding, no problems at all. Then, the following morning, after driving 500 yards, beep beep beep - motor control unit failure appears and I'm left with a car that feels like the turbo has left the county. She drove to the wedding and the following day completed the 300 mile trip home, but down on power and with no guts at all when hitting a hill.
After spending a few hours trawing this site and others, i'm confused as to the best course of action. This is where I'm after your help!
I have complete the ecu reset proceedure (or at least one of the many i found listed - disconnect battery for 45mins, turn on for 90s, turn off for 90s, start for 15m, off for 10m then drive). and this seemed to have a little effect but no where near back to normal. The engine light has stayed on and the console display still beeps and shows the warning.
Having read to try a new battery, clean / replace the MAF sensor, replace 1, 2 or 3 of the Lambda sensors, change the camshaft sensor, change the ??? and ??? sensors, replace the boost actuator (or something similar) I'm stuck with what to do next. Thing is, I'm pushed for time and cash as have my own wedding in 6 weeks and pretty much every weekend I need the car to make the round trip of 500 miles to where were having the wedding, so any quick, easy, preferably DIY routes of repair / diagnosis would be brilliant, so please send any ideas this way and fingers crossed it wont be the nightmare that it appears to be at the moment!
The car is a 2004 1.9 jtd 16v m-jet
Many thanks in advance,
