Hi guys has anyone had any experience with getting the “service active handling “ message on the C6. I’ve just had new tpm’s fitted all round and a couple of other jobs. Car was running super then on the way home from Capesthorne at the weekend up pops this message. Also the car seems to of lost a bit of power at the same time either that or I’m just getting more used to driving it, but def not accelerating as it did . Can’t be if my wife kept up in her mini on the way home lol Any help or info on this would be greatly appreciated.
