Changed oil again yesterday last of injector saga, whilst there looked at throttle cable and after a quick push on the cable thought thats a bit slack, half a turn on the cable adjuster and it drives like a different car:D
Seriously it does.
The AC compressor on my C220 CDI only kicks in when the engine has reached its normal temp. Only then, can I switch the engine off and on again and it works normally. Engine cold and it's all over again.
Suggestion leading to a repair will be rewarded.
