***UPDATE***
Hi guys....
Got my 406 back from Autosolutions here in Reading..... Still not fixed !!!
I will now type in exactly what is written on the invoice..
I just what some of you on here to give me your opinions as to their diagnostics please..
Here goes..
"Investigate cause of erratic engine idle, misfire and power loss. Carry out DIAG2000 fault code and running test. Carry out engine ECU firmware download. Re-initialise engine ECU and road test.
No faults were recorded in the ECU memory.
The running parameters check highlighted a fault with the engine ECU's interpretation of the coolant temperature (reading decreasing as temperature increased). This fault will cause poor mixture and idle control. The download and reset has rectified this problem.
The misfire is not apparent with a hot engine and may be caused by sticking cam followers (a common fault with this engine)."
*****************
There you go, thats the report I got back.
The car still runs lumpy until hot (check my previous posts for full details).
The car is a 2001 D9 2ltr with 48k on the clock. In top condition other than this running problem....
Getting to the stage now where if I can't get it sorted I'm going to have to let the car go and start with something else. This is really bugging the hell out of me...
Is this also true about the cam followers ??
PLEASE HEEEEELP !!!!
Cheers
Nick
