My X3 is the 35i model, so I am not a potential plaintiff in any N20 class action lawsuit. I suspect one of the law firms that have filed past class action lawsuits against BMW would be willing to file on a contingent fee basis a suit on behalf of owners of the X3 28i or other models with the N20 engine for defects in the timing chain system. However, one or more owners of BMWs with the N20 engine need to step forward as a lead plaintiff for such a class action, if interested.
If someone is interested in exploring a possible class action, you might send a letter along the following lines to one or more law firms, such as the ones identified in the original post:
"I am the owner of a 201_ BMW [X3 or other model] with a 2 liter 4 cylinder turbocharged engine (referred to as the N20 engine). BMW introduced the N20 engine in the U.S. X3 and other models beginning in the 2012 model year.
A number of owners of BMWs with the N20 engine have reported a failure of the timing chain guide. Many of the failures have not occurred until the vehicle was out of warranty. This failure frequently results in catastrophic damage to the engine, which requires costly repair or replacement of the N20 engine. Such problems are illustrated in the following internet threads:

On or about January 2015 BMW introduced a new timing chain guide part for the N20 engine. It is suspected this was done to address the known defect in the original timing chain guide, but it is not known if the new part solved the problem. BMW has not issued a recall to replace the defective timing chain guides nor routinely authorized dealers to proactively inspect and replace the defective guides or repair the resulting damaged engines outside of warranty coverage.

I understand that your law firm has initiated class action lawsuits against BMW for other types of defects. Please contact me if your law firm is prepared to bring a class action law suit related to the defective timing chain in the N20 engine on a contingent fee basis."
