Hi all,
ok so my garage had to replace all 4 injectors, I ordered 4 refurbished ones my garage put them in they put the codes in car started runs excellent, now the problem is you turn the engine off and when you try to start the engine it won’t fire up, plug the car in to find that it has reset the codes to the old injectors and hasn’t stored the new codes, after putting new codes back in car starts runs fine you can drive around all day until you turn ignition off and codes revert again, car has been to Mercedes even they can’t understand what’s happening so any help would be very much appreciate.
