Yep, got a TSB on this problem, although the factory fix does seem a bit Mickey Mouse to me---you judge for yourself---This repair should be on the house.
 
SI B54 14 07
Special Roofs
 
November 2007
Technical Service
 
SUBJECT
Soft Top Slams Down on the Cowl when Closing
 
MODEL
E85 (Z4 Roadster)
 
SITUATION
When the soft top is being closed, the front section of it slams down on the cowl.
 
CAUSE
Toward the end of its travel, the soft top is moving too quickly.
 
CORRECTION
Install 2 elastic straps to the soft top frame.
 
These elastic straps run from the rear bow (just above the rear window) to the main bow (in the middle of the closed soft top)
 
Each strap is secured to each side of the rear bow using the same fastening hole as the tension strap, and secures to the main bow using the outermost headliner fastening point.
 
PROCEDURE
 
Install 2 elastic straps per repair instruction RA 54 34 217.
 
NOTES:
^ It may be helpful to remove the soft top canvas cover, but this is not necessary for the repair.
 
^ It is necessary to remove the front half of the headliner. This also allows for the necessary access to feed the elastic strap from the rear bow to the main bow.
 
PARTS INFORMATION
 
Part Number Description Quantity
54 34 7 184 482 Elastic Strap 2
 
WARRANTY INFORMATION
 
Covered under the terms of the BMW New Vehicle Limited Warranty.
 
Please refer to the latest KSD for all applicable labor operations and allowances.

Too bad I just joined up for the chat. I was having the same problem same time year ago. NOT a defect, all they had to do was properly align the scissor hinges that expand and collapse the top. Although i was told same story about inherent problem. My dealer also refused to do anything after they rubbed holes in my top trying to remove the spots, probably not before the gasket would have, I had to leave my car uninvited at the dealership restricted parking area for three weeks and continually called them only when one of the owners relatives finally made it good. Also same dealership has left some kind of blemish eg: scratch , stains, tear, almost every time I have left my car for some kind of service. Funny how they make a record of all those blemishes coming in but ignore new ones coming out. By the way the top was replaced at no charge after an ordeal. When I buy a bmw a higher standard is expected, and that's why I did not capitalize their name.

I noticed the same exact problem and found that the marks were actually worn areas penetrating the first layer of the top. My car is an 07 and out of warranty. Did you have the same problem and was it resolved? Thanks.

#23 of 23 Electrical Nightmare by reidlavallee

I have heard from more than one person, that Z4's are notorious for taking in water. I am feeling this pain now. This is my 2nd Z4 and I had no problems with my first one, but this one has been a disaster. Soon after buying the car one of the power top motors died and it needed to be replaced. The next problem that I faced made this first problem seem small. I had my air bag warning light go off and I needed to have this corrected prior to my annual state inspection due this May. I brought in into a reputable repair shop that specializes in German cars. They quickly identified that all of the electronics below the passenger compartment were all corroded. The damaged sensor for the SRS system was sitting in water and everything else in the area was about to have the same problem. Rather than fleece me until the money dried up, the repair shop explained everything to me and admitted that they were afraid to keep digging for fear of what they would find.
I find it hard to believe that the dealer had not noticed any water issues when they changed out the motor about 9 months earlier.
 
Has anyone else out there seen any similar problems? Any ideas what it would cost to rewire the entire car from the firewall back (including all electronic components). It doesn't seem worth the cost. The current value of the car isn't that high. Even if I change out the electrics, it will only come back if I can't stop the water from getting in. The car has never been driven in the rain since I have owned it.
