#8 of 17 my convertible top is stuck...help! by kch82 Jun 07, 2007 (5:51 pm)
I bought a huge rug today and was going to place it in the front seat with the top down. I put the top down and something was in the storage space behind the head rest and it wouldn't open anymore...I got the thing out and it would only close...now it won't open...any ideas?

Replying to: claires (May 15, 2007 8:47 pm) I just bought a 2007 Z4 coupe. Have the same problem with my Garmin GPS. I'll take it back to the dealer on Friday. I'll keep you posted with the result of this appointment. Replies to this message: shutchin (Dec 07, 2007 8:15 pm) esfoad (Dec 12, 2007 8:38 am)

Replying to: sylvain1 (Nov 14, 2007 5:32 pm) I also just bought a 2007 Z4 coupe -- same problem -- the salesman said that as long as the lighter works, BMW feels there is no problem, end of conversation. Seems crazy -- I know my charger(s) work on other cars. I hope you will post any result from your appt. Replies to this message: esfoad (Dec 12, 2007 8:38 am)

On his Ford Taurus it works perfectly However, on my brother-in-law's 2007 Maxima, it did not work at all. So we looked closely at the plug on the unit and the socket in the car. We found out that they are incompatible. I purchased one of thos "Y" lighter cords from Walmart and that solved it. The Walmart plug works in the Maxima and the cooler's plug works in the adapter.   I know the vehicles are different but could the problem be similar?

#13 of 17 Power Steering Shutdown in Z4 by ahva Mar 03, 2008 (8:05 pm)
I have a 2003 Z4. I have had problems in the past with the power steering shutting off occasionally, when taking sharp turns, Replacing the sensor unit in the steering column took care of that. Now the power steering is shutting down driving straight. I have had the car in for service and the technician tells me that the EPS control unit needs to be replaced. According to the technician the control unit is completely integrated into the steering column, that is, the complete steering column needs to be replaced. This sounds like a major design flaw. Has anybody made the same experience? Replies to this message: Mr_Shiftright (Mar 04, 2008 8:24 am) bauvois (Jul 11, 2008 7:37 am)

Replying to: ahva (Mar 03, 2008 8:05 pm) This has been an ongoing problem for BMW, and probably replacing the entire column is their best way to try and solve it.   Many Z4 owners seem to experience this issue, if one goes by reading various forums on the 'net. Certainly NHTSA has heard about it time and again.

Replying to: kellerman (Jan 07, 2008 1:13 pm) The lighter socket is more shallow than a standard socket, so the plug-in adapters that come with cell phones and GPS units can't be inserted far enough to make contact on the side.   BMW's response to this problem (I asked) is that they don't support the addition of any third-party products.
#16 of 17 2003 Z4 top stopped working by danny2112 Apr 20, 2008 (8:09 am)
Fuses are OK, is there a manual open/shut somewhere?

Replying to: ahva (Mar 03, 2008 8:05 pm) Hello, I have the exact same issue with my Z4 (2003) and I nearly had 2 accidents already... BMW did reprogram the electric steering chip mechanism but I am still experiencing the same problem. This is very very dangerous... They plan to replace the complete steering mechanism, my car only has 60,000 km and I would like them to pay for the repair. Unfortunately they have a different opinion... Did you succeed to get an explanation or a document showing that this is a BMW known defect? Thanks and regards, Christophe
