Hi all, I am new in this forum and I hope I would be able to get help from you guys here.

I have trouble starting my 1995 W202 C280. On occasions, the engine could not be started but instead the cranking sound from the engine could be heard and both the infrared lights (red & green) on the rear view mirror will start to flash alternatively. There are power coming through the car though the lights, stereo etc are working. I have to keep turning the ignition and the sound of the cranking keeps occurring. Eventually I gave up and took out the key and waited in the car for about 2-5 minutes and then the car would start up back to normal as if nothing had happened.

This problem doesn’t happen all the time but happens unexpectedly, say that I’m going to the bank or restaurant for 10 mins and return back to the car and this starting problem will occur; leaving me to wait in the car for 5 mins before it could start again.

Anyone has encountered this problem in their 1995 C280 W202? I have replaced:
- New keys
- New car battery
- A voltage regulator (for the alternator)
- IFZ Control Module

I have done these replacements and the problem still occurs! This has been going on for 7 months now ever since I had installed a new ECU. The MB dealer don't even know what is the cause.

I would really appreciate any comments from you guys?
