W202: immobiliser

[aziz]

Hi everyone, I hope you all okay, i been having further problem with my w202...

I was parked in the supermarket car park, I could not start the car. The red and blue lights on the mirror and door were flashing at the same time and it would not let me start the car. I then decided to disconnect the battery and put it back after one minute. Then the car started fine. As soon as I tried to drive off, I slowed down and the engine kept cutting off. It did it more than 6 times. Everytime that I slowed down when approaching junction or roundabout etc..,, it stalled.

Does any one know of ths problem and how to solve it??

The cutting out sounds like the OVP relay fuse is blown.

When i did this in my C230K, I had exactly the same symptons, take it for a run on the motorway and it will sort itself out mine did.
Regarding the immobiliser lights flashing this normally forwarns you of the fob batteries need replacing.

Thank you so much, I have replaced the fob batteries and that made a lot of difference and I ran it on the motorway and now i don't have any problems. I also took out the car battery and put it back in again. Thanks for all tips...
