we are in FL and the transmission failed on my wife's Rclass. We had the extended warranty by MBUSA would not cover it. Our problem was that the transmission and car was always serviced by the MB dealer. However the dealer (like many others) was not using a MB part # for the standard transmission service. Fortunately the dealer in our city back home is covering the cost of replacement of the transmission. Unfortunately there is not a transmission in the US right now until after 2/1/12. If the trans was serviced by a MB dealer check and see if MB fluid exchange was used. If not the dealer will have to eat the transmission. Our dealer in a battle with MBUSA and they have to get their money from them.

your car reads allllllot of info based off of the speed it is moving. if the speed sensor is out or bad, the ecu will have bad or no info to make adjustments with, from or to. it is a key part in the cars performance and is one of the first things to check. im glad that the tech checked it for you. he saved you alot of time and money as most places would have replaced the part alllong with the tranny. bravo for him and i hope your car is still running well.

I have a problem with my back left tail light. When the technician checked the bulb in the parking lot he said it was not the bulb and need to make an appointment to come in. He said the brake light automatically lights up the lower bulb so I don;t get a ticket. I noticed the lead to the bulb socket is disconnected from the socket(unsoldered / cold solder joint). I held it in place with a bulb from the right side and did not work. Could there be a reset. As an electrical engineer I would love to check it out more but I am short on time. I will keep in touch with this string so I can help somebody or be helped. Depends on how much time I get to troubleshoot.

I have a 2007 R350. I have what I believe are electrical problems. When my car is cold the battery light flashes on and off. The heat and radio also flash on and office. My DvD player runs constantly and intermittently blows a fuse. Can anyone help. I had my car in the shop for a week and they could not get any codes on the flashing dash lights. HELP!!!

Hi, would like to get the perspective of 2008 (late year model) owners on the reliability of the R350. I have heard of electrical / cam shaft issues but from my research, it seems that is more restricted to '06 and '07. Is 2008 relatively okay?

I just answered that question in one of the other R350 threads -

Uhh, the C class and R class are quite different. I don't think they share many parts like the R, M and GL do.
#64 of 65 Mercedes R-Class Clock and Audio Settings reverting
Aug 27, 2013 (12:52 pm)
I have a 2006 R Class 320 4Matic LWB, recently I have had problems with the clock reverting to GMT from British Summertime (Going back 1 hour) and the speakers going from front bias to centralised each time I turn the engine off and back on again. In addition the radio is struggling to hold a good FM signal. This has only recently occurred and I cant help thinking its probably a fuse which has blown. However I would have expected all memory to be lost, but it remembers radio stations and the memorised seat settings etc... Can somebody help?
