- 2001 W220 Mercedes S320cdi & 2001 W208 CLK230K (SORN since 2008)
I have a 2001 W220 S320cdi and had an issue with a dead battery, in the past I had left it for a few days and found the battery would lose some charge especially during cold winter months but today was a bit more. I used the car on Sunday and it was fine starting and driving.
Today I drove to the supermarket and went inside for less than 20 minutes and when I came out it was totally dead. Used the blade on the key fob to get in the car and no alarm came on, not dash lights nothing, even connecting the icarsoft would not register.
Mechanic showed up and checked the battery and said there is on 0.5v showing. Nothing was left on car was simply parked and locked. When he charged the battery the alarm went off and car started and was showing 13.65 whilst running did not change when revved, stayed the same.
Anyway got it home and checked it 2 hours later and again its stone dead, keyfob will not unlock. I have owned the car since 2012 and never had the battery drain to the point where it totally dead. Any thoughts on what could cause this, I will buy a new battery as the current one is probably 5 years old now but don't want the new one draining.
In the past few weeks my clock has been going forward and back one hour randomly as if the British summer/winter times and also I do have an issue with the steering wheel sensor showing a fault linked to the ABS light being illuminated, would this cause the battery to drain?
