2006 Mercedes-Benz S430 Questions

Is the TCU located under the car in transmission area?

I was charged 636.00 for an A service. I was not over on the mileage. My car had another 400 miles before service was needed. I'm afraid to go back for the B service. How much should I be paying for the B service regular ? I have not reached 50,000 miles yet.

My car sound like a motor cycle when I am driving along at speed of about 40 miles. It don't want to change gear until I stop and trun off the car and start it again. This is just sometime. It only happen three times. Am I having transmission problems?

2006 Mercedes-Benz S430 Reviews

I love my S430. I think the body styling as well as the sleek interior cannot be duplicated. It looks, both inside and out, more elegant than the new, more aggressive S series. It ages well, and with proper service and maintenance, it can be a dream to drive.

Its a great car!
