hello, I have a w202 C180 (facelift), and I have a problem: I just installed some audio equipment, and I had to attach my amp to the battery - I did so with the small screw of the main Pos feed. All went well, however no my gearbox wont change higher than 2nd and is sooooo slow... Is this limp mode? I took the MAF of to see if it was that, and while it was nice and revvy again for 10 secs, it soon cut out completely... MAF is now back in If it is limp mode, how can I fix it without having to pay for a star machine reset? I ried leaving the engine running for 10 mins, and also tried leaving the electrics only on for 10 mins aswell, both failed to get the autobox back to normal. Everything else is fine, and theres no warning lights at all. Please help!
