It took a while to get access and be accepted into the system - I could not answer earlier.

So it looks that the problem was a bit different. I have e70 3.0si 2008, and a nasty problem.

If I drive 30 miles w the car, and stop. Starts, if tried immediately. After 30mins, tries to start w some cylinders or is rough, runs badly - after 2-4 starting attempts does not even promise to start anymore (all this in cold weather).

If I try to start after cooling off 2 hours - immediately does not start at all (in cold weather). But if I let it sit outside in this same cold weather, the next day starts immediately.

No error codes in Carly, voltage normal in engine bay, new battery (made no difference)

During Summer after this longish drive (say 100 miles) still starts, but only after 2-4 attempts running w partial cylinders/ rough.

Never stops if I get it running, so it is only the start. If it starts it runs.

If I drive short distances, like 1 mile to store and back - no problem. Only when the distance is long enough to overheat something

Drives me crazy. Any ideas?

(Some people hint to module Z11 problems in the discussion forums ab starting problems)
