P0452 - can this drain the battery

Question

My problem was that I got my 2004 clk500 from a friend and before he gave it it me he jumped the car battery the wrong way and he shorted out a whole bunch of stuff I took it to the dealer And they told me that I had to change the cem module in the trunk so they did and I got a new battery as well then it still drained the battery so I went to another mb mechanic and they told me that it is the seat module so I just changed it and it's still draining the battery now I drove it for a day and it's giving me a check engine code p0452 and if it's low out put do u think that could be my problem I need help and I don't know what to do.

Answer 1

The drain is called parasitic drain, the problem is that something is staying on after the car is turned off

its possible p0452 but are much more other systems that can drain the battery

you will have to check for parasitic drain, and pull out one fuse at a time and see if the drain drops
