when at idle a/c blows cold air ,when driving no cold air.
I drive a 2014 Mercedes Benz CLA 250, which I bought in January, I find a gradually worsening problem with its transmission, with poor throttle response and lumpy and jerky shifts under some hard acceleration. When I showed it to the dealer the first time, they denied finding any problems, however, they seemed to have reset the transmission and it worked, but after a few hours of driving, it went back to being erratic. I, now, also hear and feel a light metallic clunk during downshifts and it has steadily gone worse in terms of throttle response, be it in the ECO mode or Manual mode, Sport mode is ok (probably, due to the high revs, I cant very easily distinguish poor response).
I have read in reviews that the car is lazy in ECO mode, but my car shows a distinct and noticeable lag in throttle response (0.3-0.5 sec) even from stop, same with reverse, it needs a little more than a push to the pedal to get into motion. I have complained about this to different dealers, but they all deny any problems and insist that the car is functioning as designed. I didnt have any problems for the first month after purchase, so I was very happy with its performance then.
How can I determine if this is really a problem in my car, please advise? FYI, the fuel economy seems OK (25-27 mixed driving), but I believe that is because I am very light footed with the accelerator now, as it doesn’t offer any fun, driving normally. I can provide more details of the problem if needed.
1). what is the simplest and highest BHP I can get from this engine.
2). how can I raise the HP to above 300BHP
1999 clk430 150,000 well maintained. A few mornings ago when I tried to start my car it started then turned off two different times before it finally stayed on. it did that again later that afternoon when I left class. Then, that evening I was driving and out of nowhere it just felt like the engine switched to a lower gear. I pulled over and put it in park, then took off again. But she wouldn’t go above 25 or so. I’m not mechanically inclined, so its hard for me to describe this. Does anybody have an idea of what might be wrong? Approx $$?
I have cleaned the throttle body and all that other pipes that goes to the throttle body. I have put a new pipe that goes from the air filter to the cylinder head cover. The car does not want to start now
The problem with this car is that it doesn’t start when it gets hot. When the ignition is turned on it gives a hick sound but doesn’t run and as it cools down a bit when left about 20 minutes, then it starts.
I am looking to purchase a 2007 Mercedes C280 4matic with 100k. What signs of problems can I look for?
What? If any problems are inherent in this vehicle? Its from a used car lot and only comes with 30day warranty..
My engine coughs or hiccups once or twice when engine is under a load such as pulling away from a stop sign or climbing an incline. I replaced the fuel filter and tried diesel fuel conditioner with no improvement. No engine light on. Mercedes ran a computer diagnostics and didn’t find anything. no codes. Any ideas?
