After having my E90 (330xi) in the shop several times, the Cruise Control
failure error still comes on.

It's a yellow icon with speedometer diagram and exclamation point, and the
cruise control is then inoperative.

It happens when I set the speed with the stalk, probably 1 out of 10 times.
It registers as an orange triangle in the icon window below too. Stop/start
the car at a stoplight, the error goes away, and the cruise works fine.

BMW has recorded the error code with scanner, so they know what it is. So
far they've replaced the clutch switch. Same error. Then they replaced the
cruise control module (aka "LDM") - they had the car a week and a half and
had to consult BMW engineers. And the code STILL comes on.

Anyone had similar issues with cruise?

Thanks!

Similar - but on a Jaguar X-Type. I don't know how much of this OBD
software is shared among the marques. I was getting a code and a
"Cruise Control Not Available" message - only the cruise always worked
anyway(!?) Turned out to be (apparently, since it has not recurred) a
failed ABS sensor on one wheel. Makes marginal sense to me that the
system would include monitoring wheel speed(s).

I recently read about a similar problem (although not a BMW). Apparently
the cruise control system is somehow tied into the brake light circuitry and
depends on the low resistance value of the brake light. (This is permit
disabling of the cruise control when you step on the brake). The person I
read about created the problem by replacing the standard, incandescent
lights with LED units. The cruise control would no longer work.

Perhaps your brake light circuits (ground and/or 12 volt) have deteriorated
and have a higher than normal resistance value and it is representing itself
as an intermittent problem.
