Recently this 2007 BMW 328i came into our shop  from Carlsbad CA. that had it’s check engine light illuminated accompanied by a rough idle and a misfire. After looking throughout the car during our courtesy inspection we proceeded to test the voltage on each ignition coil. In order to complete this we used our ignition voltage checking device and checked the firing voltage of each ignition coil one at a time.   When completing our test we found that all of the coils were working properly except for one. Typically we will see the voltage change on each coil as we are testing them individually, however the voltage should not fluctuate too drastically on each one usually ranging from 9 volts to 12 volts.  On the remaining coil that tested bad, we noticed the voltage jumping from around 9 volts, up to 25 volts, down to zero volts, and so on. This was an immediate red flag for us and upon further ... read more

The BMW F80 M3 was manufactured between 2014-2018 which featured an S55 twin-turbocharged straight-6 configuration engine, with 425 horsepower. With all that power and fun, comes more stress on other parts of your car. One common area of failure that we routinely encounter is the rear differential mounts.   Rear Differential Mounts Problem The factory setup on the F80 M3 consists of a single, offset rear differential bushing and mount that holds the differential to the rear subframe. The OEM factory mount is a rubber bushing that contains fluid on the inside. Over time, these rubber mounts will begin to crack. Once cracking has begun, it can spread throughout the mount and result in more serious problems. We have seen failure in these F80 M3 rear differential mounts typically in the 30,000 – 50,000-mile range. The Best Solution The best solution that we have found to cure this common problem of rear differential mount failure is with ... read more
