Strange Electrical Behaviour W210 E240

[Vlad]

Hi,

Just taken back a very nice E240 that we have had out on Lease and its got some very strange electrical things going on...they must all be connected and there must be a reason for it:

They are as follows:

1) Electric Windows will often need the electric window button pushing down twice before the window will move and then it will only move down in 2" drops with repeated pushing of the window button between drops....same on the way up.

2) Electric Sunroof will only move back about 4" before it stops. The tilt mechanism works fine.

3) Indicators; They go Tick, Tick, Tick...Double Tick, Tick, Tick, No Tick, Tick, Tick, Double Tick, etc etc etc.

4) Central Locking is slow to respond, but does work on, surprise surprise the second push of the key fob.

5) Climate Control....function is weak.

In all other respects the car starts and drives fine.....WHATS GOING ON????????

As a complete guess is it because the battery is low and there is only just enough juice to run the engine etc and nothing else.....mad I know but I'm clutching at straws.

The windows and sunroof sound like they need resetting, the indicators sound like either a bad relay, indicator stalk or just a bad connection.

It would be worth investigating whether these all feed to the same SAM.

Thanks Dieselman,

Just to clarify.....can I reset the windows/sunroof...if so how, or do I need to go to a MB/Indi

2nd.....whats a SAM....apart from being a Surface to Air Missile

Hi Vlad,

I had electrical problems in my 2001 w210 and I changed my battery - and all cured in a jiffy.

The manual tell you how to reset all the items you mention after the battery is changed.

The battery makes a big differnce to a car that is all electronics.

Cheers
