C55 "M" mode woes
Well, after getting my C55 back after 5 months in the shop, it appears that the "M" mode isn't behaving like it should. It'll actually shift up into the next gear instead of holding whichever gear it's in. Also, in "S" mode, when I tell it to downshift, it'll do so for a split second and then go back to whatever gear it was in or won't downshift at all. Since my car has the Kleemann ECU and TCU tune, I've been told that it's still re-learning everything after the entire car was re-programmed, due to the 5-month issue's resolution.
I'm starting to think my car is a poltergeist or just f-ing hates me.

I've also heard of TCU's acting weird from many months sitting with bad battery os disconnected one.
The easyest thing is to reset TCU adaptation with STAR and see if the issue is gone

Got it checked out - turns out the switch on the right side (+) was acting up and triggering itself regularly, thus preventing the car from staying in a lower gear.
