My NBFL bj 2001, 1.6er doesn’t want to start anymore? I had a very weak battery and then my mx5 was standing for 3 weeks without moving, I thought it was due to a blank battery and then called the ADAC, battery was connected to starter set and still the engine did not start, error code was read out and it should be the immobiliser? I tried it with a second key then and it still doesn’t start. Starter works and motor turns Now the question is whether it could really be the electronic immobilizer or if it has another cause ? is this a known problem with mx5? I have read that it might also be on the camshaft sensor, maybe I would buy and replace a used sensor. I hope you still have some tips for me.
