Hello to all. I have just been to see, and test drive, my first Mercedes today! It was a C220 cdi Estate. The car seems about as genuine as you can expect, and drove beautifully. However, it did have a very noticable 'flat-spot' when trying to accelerate, particularly whilst in 2nd gear. It took far too long to reach 3000rpm, and once there, wouldn't got beyond that rpm. It was the same for all gears, but was much more pronounced in 2nd gear. I'm baffled by this. Could it be a limiter setting, or cruise control problem, or even worse, an ECU problem? Hopefully, someone can help to clear this one up for me. Many thanks in advance. Alan, in Cheshire.
