2012 Mercedes R350 DPF

Robert,

Great relief !!!! Finally convinced mechanic to pull out & clean air box/Map air sensor assy as you advised. Running better than ever cold & hot, I could not be more pleased we went down this route, no DPF to give problems in future.

Thankyou & keep up the great service you provide as an alternative to these problems.

Cheers  Peter F
