Would this be the one?

A fluid checker is available on the Opie Oils website. It's called CHF11s or something similar, and MB Parts will sell you a litre of it.

It seems like a good time to get in touch with the service department and request an examination for the used car. It would have been ideal to purchase it before the sale, but there was a wait, as you mentioned. Additionally, they can look up the vehicle identification number and inform you of any other issues that may require attention. Other TSBs may also be applicable, in addition to recalls. Do it now before the warranty expires for the best possible outcome.

Your speedo will likely simply become more accurate as a result; they are all factory-read. More importantly, while the vehicle is in full lock, I would be concerned about the clearance of the front tire arch liners.

The problem could be due to a low battery voltage, according to what I read online.

🥲

I had a message on my 2017 A220D that said "consult workshop" without shifting gears. When I put in a new battery and turned on the EML, the car started right up. Restarted the vehicle after clearing the faults, but the same issue reappears when the engine is turned off. I charged the battery again and drove, but the same problem occurred after turning off and then turning on the ignition. What's strange is that the following day, I checked the battery with a voltmeter and it only read 11.v. Please let me know your thoughts on this.

It was a simple plug-and-play installation when you added the rearview mirror. Would you mind expanding a bit?

Because the higher-powered twin or triple turbo models seem to ruin bottom ends more than the lower-powered single-turbo variants, I would recommend going with the 30d. Repairs cost an absurd amount of money, yet the N57 is becoming increasingly famous for it.

My comprehension is that if the brake pads are replaced prior to the sensor's detection (with the circuit remaining intact), the sensor remains functional until the pads deteriorate, resulting in a circuit interruption and subsequently a "low brake pad warning." Therefore, if the pads were replaced before the sensor issued a warning, it should not activate a few months later unless the garage did not actually replace the pads. It is not uncommon for unscrupulous garages to engage in such deceptive practices.

resolved The problem was a faulty engine ground. I utilised some welding ground cable and established grounding at several spots, and now everything is functioning properly.

All terminals and wires appear to be in satisfactory condition; I will utilise a voltmeter tomorrow to ensure everything is functioning optimally. The only noteworthy observation is that when I connect a wire, touching one end to the earth and the other to the engine block, a little spark occurs. This suggests that I may need to reposition the earth strap. I fitted it by connecting it to the gearbox mount on the body side and then to the actual gearbox housing.

Initially, I suspected the battery; however, connecting the jump pack directly to the battery does not initiate the start. Conversely, attaching the jump pack to the engine bay positive terminal and the body ground facilitates ignition. I am currently reconditioning the batteries.

I left the original earth strap intact and installed a new earth strap from the bell housing to the body, anticipating that an increased number of connections would yield improved performance.
