"Battery Charge" Visit workshop
Hello
I have a 2002 W220 w/ 95000 miles.
For the past month or so, I get a message every morning that reads "Battery charge, vist workshop . After a couple of minutes running, it goes away and does not come back up until the next day. I already changed the battery so I know its good.
I noticed a very low noise coming from the radio/cd while the car in off suggesting that something may be running in there but I don't feel that is whats causing the error.
Also my aromatic motor goes on in the morning for a while after that error turns off for little bit, maybe under a minute which may suggest that I have a leak somewhere, also I hear the airmatic pump on the trunk running constantly while the car is running.
I cant seem to figure out whats going on with the car, and if there is a leak in the system, where do I start to look for it.
The car does not seat low at all. It is normal.
Any suggestions would be greatly appreciated.

The pump running in the trunk is unlikely the airmatic,
it is the PSE pump generating vacuum for the soft close system (is it working OK on the doors and the trunk lid?).
Also it presurizes the lumbar support, and feeds the rear head rest up-down.
PSE must not run all the time, if it runs too long there is leak in the system. Start with turning the lumbar switch to zero and see if it affects the pump.
Find the leak, the sooner the better before the pump goes out.
