Cruise control not working after cobb flash

As per title.
Just flashed stage 1+ fmic sport onto my car. Install went fine, and the car runs spot on (from what I can feel).
The only thing I've noticed is that my cruise control doesn't work any more.


I've searched google, and I haven't been able to find an answer to my problem. Please help gents

Was your car 100% stock before flashing?

No. I was advised that the cobb flash would be fine. I would only come into difficulties when reverting to stock.

Just found your original thread buddy. I shall take a trip down to bm tomorrow. Do you mind me asking how much you paid, and what you specifically asked them to do?

Update your Cobb software using Accessport Manager.

Cruise control not working was an issue with one or two revisions of the older Cobb OTS maps.

It's more than that.

The OEM equivalent map they use on previously flashed cars is from a 335i. As a result, you'll lose cruise control when you marry the AP. Un-marrying at that point won't bring it back either.

OP - You have two choices. You can bring your car into BMW and have them flash it back to stock (they did it for free under warranty for me). They told me ~125 ish if not under warranty. Make sure you uninstall the AP first or it'll be locked and useless.

Or, you can have Cobb email you a new OEM equivalent map to restore cruise. They did it for me. I had to first extract the base ROM (there's a menu in the AP for this), then they sent me a new OEM equivalent map.

I actually tried both ways and both worked. If you've got an IJE0S I can email you the ROM they sent me with their directions...

Thanks for the info. I'll double check my rom tomorrow and pm you.

Here's a copy / paste from the email Cobb sent me. Shows you how to check your ECU, etc, and why the problem exists (335I base ROM).

This is the response I received from our engineer in the back.

Lets try this ROM.



1. Power the AP and go to the AccessPORT -> About screen.

2. Select "Export user rom"

3. Attached installed AP to AP Manager .

5. Click on the Manage button.

6. Select "All files" in the drop down.

**NOTE: The new user ROM needs to be named identically to the current user ROM that is on the AP. Take note of the current name.

7. Select the current user ROM and delete it from the AP.

8. Drag and drop the new user ROM into the AP Manager window after making sure it's named exactly what the old user ROM was named.

9. Eject the AP from AccessPORT Manager.

10. Select the AccessPORT -> About screen.

11. Select "Import user rom". This should take 10-20 seconds then a green check mark should say the import was successful.



Give you already has a generic ROM (which is from a 335i), I have replaced this generic ROM with a 135i MT ROM. This will allow your cruise control to work again when installed or uninstalled. When uninstalled there will be a code/DTC with either generic ROM. I would suggest, if you have the chance, to get your ROM updated at the dealer or a shop who has an Autologic tool for BMWs. Otherwise all should work as expected.
