Obviously you have some car knowledge and know about your car, but are you sure that you want to save the ~100€ and not go to a qualified shop with the right dipstick and let them refill it to the correct height?
I’d be furious if at some point I drove with a little bit of oil always and destroyed my transmission.
I would either try to get the correct MB Dipstick or pay the money.
Also do you have a MB Star Diagnosis? If not how are you going to check the correct oil level? You have to get the transmission to do a special venting routine with the correct temperatures before checking the oil level…
Are you serious? In no way I would stick any alibaba crap on my car. Especially critical parts such as the steering wheel and airbag. If you want an AMG steering wheel go to MB or go to a qualified saddler for them to stitch you a new one.
Again, DO NOT buy stuff like this from alibaba, it’s shit quality. It will be the cause of an accident. Or you dying in the accidental discharge of the airbag with shrapnel in it.
