Hi
suddenly (without any new additions on the car recently), my W124 estate has developed a really severe battery drain. If I leave it for about 6 or 7 hours locked/unlocked it will drain the battery completly dead - not even enough power left to crank at all.
I've connected a multimeter between the battery + and the connector and it says its pulling 12.3 from the battery.... even after i pull out ALL the fuses out the fusebox in the engine bay. I even fully removed the radio (just incase) but still it pulls the 12.3. The most change I get from removing the fuses is about 0.1.....
Any ideas? Are there any other fuses I can test for or any other test I can do.
Its really annoying as everytime I leave the car now I need to pop the bonnet and disconnect the battery, which I've been doing for about a week, so I know the battery is charging OK and holding charge.
thanks for any advice!!
