CLK55 Kleemann E-test
the car has been sitting before i just got it and it needed a battery and now if wont register it's readyness codes to pass an e-test.
Kleemann headers which delete the first cat.... is this whats causing my readyness codes to not set? or is it the because the Kleemann ecu re map?
driven aprox 900km since battery replacment, codes normally set in aprox 100km.
any help would be great
