Battery

[jimmyc320]

My 2006 C320 CDI has been standing now for just over a week while I was away and the battery is now completely flat.
Busy recharging the battery at the moment , but is there, or will there be any implications to having a flat battery. Will there be any complications with the ie. computer system.

Not the engine ECU, but possibly the window one shot and the stability system, if you have disconnected the battery to charge it.

If so just normalise the windows by pressing the switch tot eh first position and holding for 2 secs after the window hits both the top and bottom of travel. the EBD will reset with the steering turned from lock to lock.

Hi you need to get yourself a CTEK 5.0 trickle charger and just leave it connected to the battery on your car whilst not in use and it will be fine,mine stays in the garage during bad weather with the CTEK connected until I want to use,no problems since buying this from Amazon £50.

Don't think it should go flat in one week though, given that it may be 6 years old it could be getting ready to give up the ghost ...... and they do, mine failed while I was visiting my stepson at 10pm, very annoying.
