If your older Mercedes transmission is not shifting down or going into passing gear when you floor the throttle pedal you will need to diagnose the problem.

Had the 13 pin connector on the transmission changed. Car was driving perfect, changing up/down/ kick-down etc. Hi all, It seems that I have an oil and coolant leak from oil cooler on 2010 E250 CGI W212 M271 1.8T VIN: WDD2120472A296740. The oil and coolant are dripping down the left hand side of the engine block behind the starter motor and a bit further up. The starter motor is in the way of oil cooler, so I cannot see clearly. The gears don’t change until 2.5k revs and the gearbox does not employ the 7th gear on the motorway/ dual carriages. at first I thought the check engine light might be coming on because it was due a service I had a recent service ( oil/fuel/air/cabin filter change with new oil) and for about 200 miles the car was driving fine but last night
Not all the W212 have the same transmission, the 4-cylinder (E200, E220 and E250) have the 5-speed automatic gearbox, while the 6- and 8-cylinder (E300, E350 and E500) are equipped with the 7G-tronic. This has a negative impact on both the performance and driving experience of the 4-cylinder W212s.

My car jerks when cold only when rolling up to a stop line and it changes from 2 to 1 but is fine on the upshift. If yours is jerking on the upshift then that is definitely unusual behaviour and the dealer did not get to the root cause of the problem - simply change the oil and inspect the valve.

I'm afraid it isn't exactly simple even for W212 cars but ignoring the hybrid model, start/stop cars have the motorcycle size aux battery. Cars without start/stop have the small battery IF they have the electric gear selector (gear selector lever at the steering column).
Your Mercedes. W212 E350 2009. Nov 3, 2020. #1. I have had this intermittent problem for a year now. After medium journeys (100 miles+) or in hot weather, when approaching a T junction for instance and the vehicle goes below 10mph, the vehicle can throw itself into park whilst still moving (and I hear the parking brake trying to engage into the
