As part of a very long investigation into why my car drains its battery in three days of unuse I have found only one anomaly.
Have noticed that there is 220mv wrt earth (towbar socket earth and directly to chassis) on each of the tow bar socket pins with the ignition and sidelights off.
I have fitted many tow bars in the past never seen this before.
Do you think it is just a characteristic of the Jaeger Trailer Module?
This particualar bar is a genuine Mercedes approved fitted at a dealer with a certificate.
No doubt a red herring but will leave it disconnected for now as part of the elimination process.
Thanks
