Hoping fellow members and GLA C200 owners can put my worries to bed before I go to Mercedes to take a look at it.
I’ve got a 2025 GLA C200 petrol, only done around 1500 miles on it since new. After the first 300miles, I noticed it produces a rattle on acceleration at low speeds between 5-25mph in gears 1-3. I don’t know if the noise was there from day 1 but I only noticed it around the 300 mile mark. It sounds like an old diesel van needing a new timing chain or, dare I say, a car with spun bearings (don’t ask me how I know!).
It’s not loud, barely audible in fact until you drive along side parked cars or a wall with the windows down, by which point it can be heard quite easily. Noise completely disappears when doing 30mph+.
It’s not spun bearings as there’s no rattle when revving at a standstill (also, no blue smoke) so I’m fairly sure that it’s the timing chain.
Maybe it’s just a characteristic of these engines and they’re all rattly at low speed?
