Hello to everyone,

have an issue with C 63 AMG steering pump - car with some 40 000 km only has eaten 4 steering pumps so far!!! It has a Carlsson CK 63 S kit fitted (540 PS / 685 Nm), but in my opinion this has nothing to do with the problem - every 5 000 km the flatbelt cracks, two times the steering pump was leaking and two times it exactly pulled the shaft out of the pump body, which went to the pieces this way. MB workshop doesn´t know what to do now (many times checked all the pulleys, bearings, belt fitment and adjustment...) and says it´s probably caused by the power increase...
Any experience like this & idea what to focus on?

Thanks & regards,

Ivo
