Hi Manny,
Thank you for taking your time and giving me your advice! I did turned the wheels as you instructed me. Basically nothing happened. But, this moment, the car drives good (I drove it) although the "Check Engine" light stayed on. This was the situation yesterday too, and the light goes off after a while. The brakes work fine, there is no problem there. I thought that I use the car too little (7 years old and has no 4 K miles just jet) is the problem thus (as I promised to my wife) I thought to use the darn thing more. I service it very nicely (myself) regardless of the mileage, the synthetic oil was changed 11 times and the MB coolant annually but the transmission is the kind what you do not needed to change the fluid. The car is in the garage - covered - washed three times in the seven years still not dirty (California car - you know, but I do understand that by time things goes wrong. Especially with the MB. Looks to me that better if I take it to a service station (not the dealers' though - biggest in the US but lost a nice lawsuit because they used mineral oil (!) instead of the synthetic, - with nationwide ramifications!
Thank again being helpful!
Paul
