Hi guys,

Last week my 35d died while I was driving it and it refused to start again.
It was cranking without an issue, but wouldn’t fire. There were a series of errors on the screen including “fault in drive”, “driving stabilisation failure”, “DBC failure” and “fuel pump”.

I plugged in my basic OBDII scanner I had at home and no codes were displayed.

The roadside assist guy tested the battery and said it was fine, so I had it towed to the dealer.

The dealer has had it a week and yesterday when I went in, they said it was probably a comfort access control module issue and possibly a bad battery too. They’ve also said they’ve been able to start it and the issue is intermittent. They said the module would have to come from Germany pre-coded to my car.

Now, I’m fairly certain my car doesn’t have comfort access. I even put my VIN into a BMW VIN checker and it didn’t come up as an option on my car. Even if it did, would this cause a cranking but no start issue? I can’t find any evidence on any forums that this could be the cause of my no start issue.

Thank you in advance!
