$4400 quote from mechanic for new ECU and ISM. Can I repair myself?
Hello, my m235i wouldn't start so i took it in and they say i need a new ECU and a ISM. They are quoting me $4400. I have done car work in the past and feel comfortable doing this type of work but I haven't reprogramed my BMW before so I was wondering if this is something I could attempt or is it better to just let them do it? Looks like the ECU costs around 2k and the ISM is about $200 so labor is going to be about half of this cost. I've seen a couple youtubes on this topic and it doesn't look that bad but I was hoping to get better info from someone with more experience. I don't mind paying the cost if the quote is accurate and the job is out of my league but in these situations i really like to do them myself especially if it means I can buy the tools i need for the job and I still save money compared to what I would have paid the mechanic. Thanks a bunch, rick

It’s not too hard to replace both of those control units the only issue that u will have is that the vehicle will need to be programmed and encoded since new control units are being installed and for that u need ISTA.
