• 2019 Mercedes-AMG C43: Lacking power when accelerating

  Colleagues of mine have noted that the C43 isn’t at its happiest when taking off from a standing start sometimes, particularly if the stop-start function is engaged. That said, the harshest description of the problem was the odd clunk when launching the car, but even with that system switched off, the AMG sometimes seems to have problems deciding which gear to select, leading to a lack of smoothness. Perhaps it’s not helped by the fact that the car is all-wheel-drive, and grips the road extremely well when perhaps a little `give’ in the driveline mightn’t be a bad thing. Maybe it’s the traction-control stepping in too early and interrupting the flow of power to the wheels.

  That said, your problem sounds a lot more severe than that. The C43 uses a conventional torque converter automatic transmission, so it doesn’t suffer some of the jerkiness that other cars using dual-clutch technology can. It’s puzzling though, that the computer isn’t throwing up any fault codes, so maybe your car is simply doing what some C43s do to a greater or lesser extent. If it’s as bad as you say, it’s not good enough and you should pursue the problem with Mercedes-Benz and have the problem corrected under warranty.

• Mercedes-Benz C200 2008: Does the timing belt need to be changed?

  I’ll assume you’re talking about a C200, Kevin, which was the most popular Benz model with a 200 in its name back in those days. The good news is that, no, that engine doesn’t need a timing belt change. That’s because it uses a timing chain rather than a rubber timing belt and, all things being equal, the timing chain should last the lifespan of the car itself.

  All Mercedes-Benz passenger cars from that era would all have been sold brand-new with two keys. If you’ve bought the car second-hand with just the one key, you can contact a Mercedes-Benz dealership, quote the car’s VIN and the dealer will be able to order the correct key and electronically code it to work in your car. It could cost several hundred dollars, however.
