W220 Battery Discharging for fun

[nadeem123]

I have an ongoing problem starting problem with my S320CDI

Intermittently the car completely discharges the battery and will not start. Often even boost charging requires connection to the slave vehicle for 10 mins before it will even crank.

After starting a variety of malfunctions are displayed, usually that the Steering wheel is in the park position and the car should not be driven, even though it is not.

Have had the vehicle with 2 "specialists" who have reset the faults and said they could find nothing wrong. After the latest occurance they were adament that the wrong battery was fitted and fitted a "Gel" type battery costing £150. After 24 hours the car is completely dead again.

Anyone experienced anything similar?

Nine hours times 0,09 amps equals less than one Ah. This is nothing from your big battery.

Is it the W221 or W220 320CDI? Did you measure the main battery or the starter battery?

I'm afraid there is a bigger consumer but it did not happen when you checked the quiescent current.
