FAQs—Mercedes Benz B200
While I was driving on the highway, my Mercedes Benz B200 suddenly stopped shifting automatically into gear — it froze. I had to pull over at the side of the road and turn off the car to restart it. This has happened at least 6 times in the past months and I don't know what I am dealing with. Do you have any suggestion on how to handle this situation?
Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition — most commonly when shifting gear from first to second and going down from third to second gear. The technicians over at Mercedes think that this is due to an internal component failure and the solution is to remove the transmission and disassemble it to repair the part that has failed. An automatic transmission uses a planetary gear system to transfer power and create gear ratios and reverse option. This gear set has a single center gear, a large ring gear around that with internal teeth and multiple small gears. If one part of these gear sets fails, it often renders the whole system inoperable.
My Mercedes Benz B200 has developed a very tight steering issue especially when the car is stopped or moving slowly. I can feel spots when trying to turn the wheel and at some point it becomes very difficult to turn. The problem seems to ease up after a decent amount of driving time; but it's getting annoying for shorter commutes because the problem will be persistent then. Any idea what's going on?
You may be dealing with a power steering rack that has developed a fluid leak and you may need to replace the entire rack assembly. Basically, as a car ages or reach high mileage, the O-rings and seals in the power steering rack lose mass and form. These seals could even break up into little chunks and circulate in the power steering fluid. When the seals are broken, the fluid will start to seep out. When this happens, you will need to replace the entire steering rack because it is very rare for seals alone to be repaired or replaced.
Something is causing a drain on the battery which results to a dead battery every 24 hours. It's getting annoying because I have to recharge the battery every day. The other day, I had to have the car towed because it just died in the middle of the road. I was told the fault is in the battery itself, had it replaced but still no luck. Do you have any idea what's causing this problem?
A battery drain can be caused by different things in your car that may remain on or stuck. These may include lights, car radio, mobile charger, and relays. But, if you've already checked all of these and there is still something that's causing an excessive drain on the battery, you might want to look in the seats. If your car seats are constantly getting spilled with liquids, there is a risk that the seat control modules can get damaged and will start to fail. A failed car seat module does not properly shut down and will continue to get current from the battery even if you thought you already turned it off. It is kind of difficult to DIY this sort of problem so you might want to take the car to the shop to fix the problem.
