Power Steering Malfunction
Hi Gents,
I needed to inspect my W204 C300 (2009) drive shaft, so i put in on a lift and did run it to inspect it, i used the engine power to turn the wheels for couple of minutes. As soon as I accelerated a bit a message pops saying : " power steering Malfunction See Operator 's Manual" followed with "EBR, ABS, ESP Inoperative See Operator 's Manual" with the ESP ! light on.
After i completed the inspection, i went for a test drive and as soon as i hit around 20 km/h, same message pops again and ever since.
I noticed playing with the settings of the car that there is a dyno mode, and i should have used that when i tested the car on the lift but i did not.
I did some troubleshooting without success,
I tried reading the faults but nothing related (had some evap system issue was there before) cleared all the faults but the issue still comes back.
I tried draining power from the car to reset all the computer, but no success issue still comes back.
I tried resetting the steering angle sensor with full right and full left steering no success.
I'm not sur what are my options here, is there some kind of trouble shooting or solutions you guys know?
thank you,
Ouss

I had this same exact issue. Believe it or not I tried this method on post #10 and 24 hours later the errors were gone. Figured $10 bucks out of pocket was worth a shot. Mine drove fine no issue except these warning lights after 2 min of driving. It's been error free for over 2 months. Knock on wood..
