Front Air Bag Sensor Control problems of the 2008 BMW 750

Passenger restraint warning - apparently the passenger seat sensor has failed and the passenger airbags have been automatically disabled. A quick search shows that this seems to be a fairly common problem with BMW passenger seat sensors. There was even a recall for the issue, but the dealer claims my 2008 BMW 750li wasn't included in the recall (only 2006-2007 BMW 750li's). This car was built using the same parts. Shouldn't it be included in the recall list? apparently the problem is so common that people are building "sensor bypass" devices and selling them on amazon/ebay to place the passenger airbags into "always on" mode. This kluge doesn't sound like a very safe solution, since small children could be injured by the airbag system if it deployed unnecessarily. Dealer has quoted nearly $1,400 for a fix. Bypass solution less than $100. Seems one has to choose between relative safety or not blowing the savings fund. All to repair an obvious design flaw.
