Hello people! Reason: Entry of oil into the control unit through the wire harness! Remedy: An adapter plug that costs just about 22 Euro at MB. I would like to ask ALL of you who have an M111 engine: Take the opportunity to visit your MB workshop and ask for such an adapter. The installation takes not 5 minutes and is free of charge. Your control unit will thank you with loyal services Here the affected motors: M111 E18: 1.8 liters, 1799 cm3, bore 85,3 mm, stroke 78.7 mm90 kW (122 hp) at 5500/min, 170 Nm at 4200/min C 180 (W202) C 180 T (W202) M111 E20: 2.0 liters, 1998 cm3, borehole 89,9 mm, stroke 78.7 mm100 kW (136 hp) at 5500/min, 190 Nm at 4000/min (partly reduced to 95 kW) C 180 (W203) (95 kW; until 2002) C 180 T (W203) (95 kW; until 2002) C 200 (W202) 200 E / E 200 (W124) E 200 (W210) CLK 200 (W208) SLK 200 (R170) M111 E22: 2.2 liters, 2199 cm3, borehole 89,9 mm, stroke 86.6 mm110 kW (150 hp) at 5500/min, 210 Nm at 4000/min C 220 (W202) 220 E / E 220 (W124) M111 E23: 2.3 liters , 2295 cm3, replaced the 2.2 liter, more torque and quietness 105 kW (143 hp) at 5400/min, 220 Nm at 3800/min (for transporters) 110 kW (150 hp) at 5400/min, 220 Nm at 3800/min C 230 (W202) E 230 (W210) ML 230 (W163) Vito, V-Class (W638) Sprinter 214, 314 (W901-905) M111 E20 ML: 2.0 liter compressor 120 kW (163 hp), 230 Nm (export models up to 141 kW) C 200 T compressor (S202) C 200 compressor (W202) (export only; 132 kW, from 1996 onwards 141 kW) C 200 compressor (W203) (until 2002) E 200 compressor (W) 210) (also as export version with 141 kW) CLK 200 compressor (W208) (up to 2000 only export with 141 kW, from 2000 also domestic with 120 kW) SLK 200 compressor (R170) (up to 2000 only export with 141 kW, from 2000 also domestic with 120 kW) M111 E23 ML: 2.3 liter compressor 142 kW (193 hp) to 145 kW (197 hp), 280 Nm C 230 compressor (W202) (142 kW) C 230 compressor (C203) (145 kW, 2001–2002) CLK 230 compressor (W208) (142 kW, from 2000 145 kW) SLK 230 compressor (R170) (142 kW, from 2000 145 kW) Greeting
