SMG programming issue

Having my car for 5 weeks now in repair. It started with the pitch sound (weeehee) from under the car. Weeks before the breakdown the sound kept going, weeh after weeh. Then at a certain morning the gear got stuck in N and car didn't start. Brought car to technician, replaced the pump, but then... reprogramming (loading software) failed, time after time. this is the procedure they take 24h for.
Electronic module of SMG replaced, but still problem continued, replaced more parts in total 1200,- euros, but problem continues. It seems the car is not programmable. Now the car will be taken to a BMW garage in Belgium (1 hrs driving), they have expertise with these kind of gearboxes. But they give no garantee, rather have not the car, and ask to be paid by the hour. I don't know where this road is gonna take me.

Any idea what the real issue could be?
thanks Matt
 
Sorry to hear that fella... There arent many SMGs on the Z4, so you might get more info on one of the E46 forums? Hope you can manage to sort it soon...
 
Hi Matt, I think "jimbo1958" had a gear selector problem with his SMG 'box.
I think this might be the the topic - http://www.z4-forum.com/forum/viewtopic.php?f=3&t=26646
There are some folks folks who have had their pump or relay replaced. I would have a search on the forum for these topics.
