Peugeot 208 makes a knocking sound when putting it in reverse. - 208

My car is a Peugeot 208 1.6 HDI ETG6 with a robotic transmission, 153,000 km, I just bought it. Normally, there was no noise when shifting gears, but today when I put it in reverse, there was a knocking sound. There's no problem with the car's driving, and the place I parked is on a slight incline, not too steep. While parking, there's a knocking sound when I put it in reverse, and the car shakes when I put it in forward gear. I fully press the brake when shifting gears, but the car shakes no matter what. Even if I put it in neutral, it shakes. Apparently, it's common for Peugeots to make noise when putting it in reverse, but my car never did this before, it's new.

As someone who has driven the same vehicle, I can say that a very slight clicking sound when shifting into reverse is considered normal in this transmission, but the fact that it's a new issue in your case and the jerking when shifting forward and backward isn't very normal. Especially if you park on a slight incline, the vehicle puts stress on the transmission, and when you shift into gear, that stress is released, causing a knocking sound. Try this: first press the brake, then engage the handbrake, loosen your foot slightly, and then shift into gear. If the sound decreases, it's most likely the problem. But if the jerking is present in all cases, at 150,000 km, it's highly likely to be the engine mount or transmission mount, which is quite common in these vehicles. Also, since it's an ETG6, if the clutch has started to wear, it can cause the same kind of knocking and jerking. Sometimes, a weak battery or misalignment can disrupt the transmission adaptation, and it can be fixed by computer calibration. In short, it's not something to dismiss by saying "that's just how Peugeots are," but it's probably not something to worry about too much either. If I were you, I'd first try the handbrake issue, and if it persists, I'd take it to a mechanic to have the bearings, clutch, and adaptation checked. GökhaN2026-04-20 01:53:17
