Replying to: Mr_Shiftright (Jun 05, 2009 10:08 pm) If the electric/hydraulic soft top motor is bad, the windows should still go down, and the top latch should disengage. But the top won't power down any farther than that. It seems like some people have been lucky recently getting BMW to cover the cost of the repair, others have been paying a little under $2000. I would imagine the better the customer you are at a dealer, the more likely you are to get the repair done for free. That said, I understand BMW extended the warranty on the soft top, but my 2003 still falls outside the range, even though it only has 39,000 miles on it. And given that I like to do my own repairs, I'm not in the good customer category, and will probably tackle the repair myself.

Replying to: Mr_Shiftright (Jun 06, 2009 2:13 pm) Now the interesting thing is that I am also having problems with my outside temp sensor. I keep the car outside uncovered ( I know, horrors...) and when it's been very wet and damp outside and I start the car, the temp sensor indicates -40 degrees. As the car warms up and I drive the temp rises to almost normal, and then may drop again. Now mostly this is annoying, but I noticed that when the temp was in the neg range the tops wouldn't work. But when the temp went up it did. While I was reading the manual on how to put the top up manually, it mentioned not operating the top if it was below -10 (or so). So other than it may be a general short in the system that is also affecting the top, couls it be a temp interlock that prevents operating the top in really cold temps to prevent cracking? Sorry for being so long winded...

Replying to: ahva (Mar 03, 2008 7:05 pm) I had the same issue today coming into work. I have a 2005 Z4 and live in northerN VA. The power steering light came on abruptly thrice and shut of the electricals in the car i.e. the nav screen folded in and up suddenly. Something tells me I need to be on the lookout for a hefty bill...please advise as to how you remedied this problem and the cost (if you don't mind). Thanks!

There are two senders in the fuel tank (at least on my year) and one was bad. So they had to drop the gas tank to replace it (access ports in the trunk would have been a good design idea). I think the final bill was over $1k, I don't remember the exact price (brain tries to protect itself after a traumatic incident). I also had them fill the tires with Nitrogen, the car actually ran better with that (I'm not using run-flats).

Sorry for getting back so late on this. The temp sensor had a loose connection. They played around with it, and it appears to be OK. Thankfully only took 1 hr labor. They did verify that the top is interlocked with the temp sensor, so, below 40 degrees top won't operate.
