One a tha last thangs Hanz und Franz told me at Heavy Karls was thet ah had to have them pull the intake manifolds to grind off the carbon to get the engine warning light to turn off. And it would only cost about $1500. So smilin sam and tha boyz sort of laughed, looked at the light and found a burned out relay. Total cost for the couple of hours of diagnostic work and then relay installation was around 150. The light has stayed off. There is an EGR valve or some such thang whut takes them ole bad exhaust fumes wif raw unburned gas and dumps them bak into the intake manifold. But it is the valve, not the manifold which on rare occasions does carbon up. You can replace the valve for 300 or so. Reallllllly defines the MB dealership, doesn't it?
