I have strange problem with battery.
It was perfect and never gave any trouble , one day I parked at work and when came back it refuse to respond at all, called AA and he jump started and said battery looks OK as it taking good charge. I drove 20 minutes to home and when I parked I checked and battery was ok, after 20-30 minutes it works fine again but next morning it was flat. Replaced the battery but it went flat again within 2-3 hours.
I started looking forums and found out there are many people with same problem.
In short.
I have replaced battery.
When battery is charged it gives 12.5** Volts, and 16+ Amps current drain when car is switched off
I have checked all fuses one by one at three different locations, I have disconnected many leads/jumpers as well, but current drain remain at 15-16 Amps. My local garage now have no clue and I am scared of huge bill by taking this to Mercedes.
Please let me know if you have any idea...
