2008 BMW 335xi Problems

Adaptive Headlight Module

The adaptive headlight modules located under the headlights are positioned strange. BMW decided to locate these under the headlights themselves.

2008 BMW 335xi Recalls

Driver's Frontal Air Bag Inflator Ruptures And Sprays Metal Fragments

The driver's frontal air bag inflator may deploy the air bag with excessive pressure, resulting in the inflator rupturing and causing metal debris to be sprayed onto vehicle occupants. Dealers will replace the driver's frontal air bag free of charge to resolve the concern.

Side Air Bag and Safety Belt Tensioner May Not Deploy

An incorrect crimp connector may have been installed on the side air bag and belt tensioner wiring. There may be insufficient contact in the wiring, creating high resistance. This condition may cause the side air bag and/or safety belt tensioner not to deploy if needed in a crash, which increases the risk of injury. Dealers will repair the vehicles free of charge. The recall began September 16, 2009.

2008 BMW 335xi Reviews

Hopefully I am replying to the post in 2012 (and ones from 2019)about the noisy tires. Just bought Michelin MXV4 ZP (zero pressure) run flats from a local discount tire to me in indianapolis IN for 150 per tire. They are so quiet compared to the prior Turanza El42s I can't believe it.
Bought my 33xi used with 8,000 miles. The run flat tires are terrible - rough, jarring ride. Huge improvement when I switched to 18" BBS rims. Am worried I have a fuel pump issue
Great car. Well balanced. Good comfort. I an selling and purchasing a new Audi A4 after only 35,000 miles. TIRE NOISE. Dealer suggested 528xi at $50K to solve THEIR problem. Have loved BMW since 2004, 2002. Enjoyed the 335xi and am going crazy with tire noise which BMW does not care to address. Good buy? No.
