Hi, I’ve just joined the Forum as am in need of some advice. I have an old Mercedes A Class and the headlights intermittently flash on and off even though the lights are not on. My garage have told me that the ECU is defective and that is causing the problem. A new ECU would cost around £1400 so I’ve been looking at second hand units. The trouble is that I can’t find the exact same part number. My unit Merc No is A640 150 47 79 Bosch No 0281 012 430. I have found an ECU on eBay but the last 4 digits are not the same, i.e. Merc No A640 150 49 79 Bosch No 0281 012 432. The question is how important are the last four digits and basically would this part fit my car. Any advice would be much appreciated.
