I have a N reg Mercedes E300. I am having trouble with my immobilizer, the keyless entry will unlock the car but i am unable to start the engine. Mercedes told me to change the batteries in the key, which i did & it worked fine, but then when i came to start the car again half an hour later the same happened.
The red & green lights in the rear view mirror, ( once immobiliser usually turned off they flash green, i think) but now the red & green lights are flashing.
Does anyone have any ideas on this as have been told that i need a complete new immobiliser system. Any help gratefully received, as i use this car for my chauffeur business and at the moment the car is sat still outside the car & the business not making me any money...
