Mercedes C Klasse Diesel engine issue after chip tuning

Reduced engine power and an error after chip tuning Sounds familiar I also drive a C Klasse though a newer model Did you happen to use a scan tool to check the specific error code It could be anything from a faulty sensor to issues with the ECU itself after the remap Is the car running rough or is it just lacking its usual punch Because if you have not checked it I would suggest you start with an engine issue

Thank you for your prompt response Indeed I utilized a scan tool to retrieve the error code but I confess my interpretation of its precise implications remains somewhat uncertain The engine does exhibit a degree of roughness particularly during periods of acceleration Could you perhaps elaborate on the specific error codes you encountered during your analogous experience Any further insights you might offer would be greatly appreciated

Unfortunately I do not recall the exact error code offhand The issue stemmed from an improper remap that was overloading the turbo If the engine is running rough and you are not an expert you should probably take it to a workshop It could save you from causing further damage Better to be safe than sorry wouldn't you agree

I extend my sincere gratitude for your invaluable guidance Based on your recommendation I sought the expertise of a trusted mechanic Following thorough vehicle diagnostics it was determined that the chip tuning was indeed the root cause of the issue The affected component has been recalibrated and the error memory cleared The total expenditure amounted to 180€ Once again thank you for sharing your insights and averting what could have potentially escalated into a far more costly predicament
