ml270 cdi 2002 all fault lights and a/c turn on when not running

[Wishbone7]

Hi guys, my entire array of fault code lights and a/c will just sporadically all turn on when the car isnt running which obviously drains my battery. Ive removed the a/c relay (still have a/c, go figure) so im thinking it may be an ignition fault instead. Any ideas?

Cheers

Wow. Haven't listened to them for years. They were pretty damned good from what I remember.

Have had an auto electrician and a couple of mechanics briefly look at the car. Had 5 relays replaced then, lost a/c. A mechanic then came out, tried to diagnose with Star and had every known fault code (hence all warning lights on dash) and removed and replaced the k22 relay. This seemed to reset everything. The problem returned a few weeks later. I've sinnce removed the k22 relay and have noticed that its not actually connected to anything as far as my diagram/list goes.
