This is in regard to NHTSA id #10033607, also Mercedes Benz service campaign #2009100002 dated Jan 2010, for model 163. My vehicle isn't covered by above Mercedes service campaign because it's V-6 model, but showing exactly the same safety problem. I've taken and attached a few photos of the problem area showing severe damage to fuel line and less so to brake line. The photos showing severe chafing between fuel line & brake line just below master cylinder. The service campaign only covers 8 cylinder models, but my 6 cylinder model is showing exactly the same chafing at the same area. I have not experienced any problem, but just noticed this issue last few days.

ML320 6-cyl

Uncommanded breaking of front wheels resulted in deceleration and severe overheating of front brakes. This occurred within one mile of destination. High engine revs and downshifting of the transmission were required to overcome the uncommanded breaking force and reach the destination. A similar second occurrence effected only the right front brake.
