RESOLVED - AMG not as smooth - codes p203b-016 / p203b-064 / c1038 / c1022
In the last 24hours my 05 SLK doesnít seem quite as smooth as it once was. Its not bad and no one else notices but to me itís not quite as perfect as it was.
It feels more like the gear changes are a bit clunky so I have put a carsoft code reader on it. The transmission is fine although there were codes in some of the other modules. Iíve googled them but got myself confused as I have seen the same codes listed for ecu, o2 sensor, acc pedal and DPF (really odd as itís petrol not diesel)
For the slk, please has anyone had the following and know the solution. p203b-016 / p203b-064 / c1038 / c1022
All of the others seemed to have meanings with non relating to the engine or gearbox. I also cleared all the codes and so far only the first two came back. I also have a battery tester on order as while I have good battery voltage and the car does start, I have a few other niggles which could be battery and I do know a poor battery can cause so many issues.
Also, there are no warning lights on that shouldnít be etc, the gearbox oil was changed a few months ago with the fluid that came out looking in ok condition with the correct fluid going back in to the correct level. (Also I donít believe there to be any leaks as there are no drips when parked although I havenít being underneath to look).
Thanks in advance.
