Hello I own a W209 200k Bj03 with the M271 engine have on my car now already almost 110000km on the clock of course comes always the thought, that this is not a low power and how long it will take the engine.. must say, am not a slipper! drive also once on the highway 230 (if possible). The car is always 10-15km warmed by me until I turn over 3000u/min. and I let the engine run every time at the car at least 15 seconds (wayway en Compressor) Short distance is as good as it can be avoided! so my car is always TOP maintained and regular oil change every 25000km! drive a little 20000-25000km annually (but mostly more 25000km) what do you think the durability of an M271 compressor engine is like? does someone have the same engine, without problems and with high mileage? would be happy about your answers… until then, good drive and still a nice Sunday
