On my w211 e220 the battery is flat in a couple of hours.
We have found that the cluster was drawing too much current.
We disconnected the cluster and the battery drainage was significant less.The car could start at any time without problem.

Did anyone has encounter a similar problem and manage to repair the cluster.?
I am hoping that someone would have manage to repair a cluster with this problem

A new cluster is quite expensive

Please help

If the cluster were to run the battery flat in a couple of hours (assuming your battery is good), it would have to drain tens of amps but it does not even have big enough fuses for this.

I'd suggest you to measure accurately where the drain actually appears when the cluster is attached.
