Hi, my 1.9 318ci seems to have an issue with the asc module.

The ABS and ASC lights are ON on the dash, so after some research I've changed the abs wheel sensors, and that didn't work.

Took it to my usual mechanic and he noticed some fuse kept blowing up, so he suggested an auto electrician to have a look at it, now the auto electrician is saying that everything is pointing towards the ASC module/ABS pump.

Now the problem, I got the part number, put it on google and it only shows new parts which are about 200. The second hand ones are a lot cheaper but don't have the exact same part number?!

How exact the part number has to be? Is there different modules for the same car?

Could it be something else?

Thanks in advance
