Hi, I tried replacing an in-dash DVD player in my Sharan and didnt realise that the heated seats were on! Only noticed something was amiss when the digital clock / milometer display disappered. Noticed that the battery indicator on the dash was showing 8volts (normally 14v) but was reassured to find out that the car started normally and thought that it will recharge as I drove around. However, this has not happened and other side effects are no power for the tape player (gave up with the additional DVD player) and the central locking locks /unlocks all doors ok except for the drivers door which now works the opposite way to the rest of the doors, ie it now locks when I press the unlock on the key fob and vice versa! Checked that all fuses are ok, electrically, everything else is working ok and have no problems starting the car? Any help will be appreciated. Thanks
