Since last week my ML270 cdi 2001 93.000Km do not run more than 130 Km/Hr. No warning lights on.
I ckecked the air mass sensor, turbo sensor, air filter, diesel filter, catalitic converter, inyection sistem and everithing works OK.
The fuses in the first E-box are OK, but I culd'nt check the fuse of the second E-box because I culd'nt find it.
In the cover of the first E-box there is a tape indicating that,"fuse f-24/8, 7,5A, Diesel Engine Control Unit is located under lid of second E-Box".
Can somebody tell me where is located the second E-Box???
Of couse is not the one located in the cockpit pasanger side.
Can somebody tell me what else to check??
Also , how can I get a Service Manual for this vehicle.

The ML 270 has more fails in one year that my 300 TD in 25 years.
All the best
