Hi All,
My 1995 405 glx estate with XU7 - 8 valve tends to pink when fully warmed up on a long run. The engine has done about 60k miles from new and performs well in all other respects. the ECU is a bosch model 5.1
Does this engine /ECU have a knock sensor and correction capability?
I have downloaded the error messages from the ECU and there are no problems logged. In the manual, there is a code for a faulty knock sensor but I don't know if I have one fitted.
Where is it and what does it look like please?
As I have phobia about going anywhere near Pug dealers, I'd like to fix this by some other means.
Anyone else have this problem? Shall we form a support group?
Regards
Bob
