W176 200d auto gearbox problem

[Lemmand]

Hello everyone, I was hoping someone could lend me a hand. There have been problems with the transmission in my 2017 W176 a200d Automatic (62k miles). Several warning signals appear on the dashboard (see images) and I suddenly lose control while driving. I had to coast to the hard shoulder because it happened the other day in the fast lane of the highway. It was not fun! It can only be started by coming to a complete stop, shifting into park, and then back into drive. At any speed and in any driving mode, this is possible. There is no engine management light and no fault codes are kept. A Merc specialist checked the software for updates, changed the oil in the gearbox, and attempted to read any problem codes (none were stored). Even with the oil change, it's still happening, so I'm scared to drive it because I have no idea when it will happen again.


I would much appreciate any assistance.

Surprisingly, there is no database for fault codes. Was Star /Xentry the tool the specialist was utilising?

Since it was sent to them by the garage from whom I purchased it, I'm taking a wild guess, but I can't be positive. Tomorrow, it will be taken to a nearby mechanic for another inspection, however I am not expecting very optimistic results 🙄.

This is only a wild assumption on my part because the garage from whom I bought it sent it to them; however, I cannot be sure. The vehicle will be taken to a local mechanic tomorrow for another examination, but I am not anticipating positive outcomes 🙄.

I don't think the gearbox oil has been changed before, but I've just had the car since December. The oil was changed at 62,000 miles. The prior owner may have been a city driver, but I've only owned the car since December, so it's possible they were.

Presumably purchased from a dealer?

If that's the case, the Consumer Rights Act will pay for repairs for up to six months after the purchase, when the defect was first noticed.


The validity of whatever warranty you may possess is moot. It is the dealer's responsibility to either fix it or give you your money back
