Mercedes E200: doors keep locking themselves

[deirdreives]

Hi - I wonder if anyone can give me some guidance on my problem ....
May 2005: The Odometer Clock suddenly turned back to 0000 (on my Mercedes Benz E200 Classic 1996) – Mercedes dealerships were contacted who had not heard of this problem and said it was not in their power to revert it back to its proper mileage.

July 2005: The doors start locking by themselves and will not open with automatic door opener.
In the mornings when I would try and start my car the battery would be totally dead.
I brought it to my local trusted garage owner (who has a very large business and is a good friend). He checks the car out and says that he cannot find a problem but, from the car repeatedly locking itself the motor that controls the doors has burnt out and has to be replaced. As he could not find out what was causing the problem himself he brought my car to two Mercedes Dealerships.
The first Mercedes Dealership had my car for two weeks and did every test, but could find nothing wrong. The second Mercedes dealership had my car for several days and they neither could find any problem. My car was returned to me after a month and a series of large bills that needed to be paid.
The problem seemed to have subsided on the cars return – however, a month later it was back with a vengeance.
This time I took my car to a dealership whom I originally had bought the vehicle from. They too could not find anything wrong and decided to take out the alarm system, as they thought this being connected to the automatic doors might be the problem. With no alarm and three weeks later (and another huge bill for services), my car was returned.

Alas, after three weeks the problem has returned again. My Car is locking itself whilst I’m driving, stationary - ALL THE TIME.

EVERYONE IS BAFFLED. No-one knows what the problem is.

I take really good care of my car – it is kept in my garage and not used for long distance travel and huge mileage as I am a mother of three small children and do not travel thousands of miles per week.

My real and very logical concern (which I have nightmares about) is that the car will lock whilst my two youngest babies are inside and I’ve left the keys in the ignition while picking something up or unloading the babies’ strollers. The car has locked several times like this already but thankfully on those occasions there was always an older person in the car who knew how to open the door from the inside.

I went out to my car this morning and the doors were locked and wouldn't open with the automatic opener - I opened them manually, strapped the kids in and tried to start the car - it was as dead as a dodo HELP!

Anyone know whats going on ?
Thanks
