Get a real battery charger and just use the trickle charger for when you don鈥檛 drive it. Important Links. Save. J. But our Sparkling Graphite Metallic M3 did indeed win us over. For less than $70,000, the M3 bolts from a standstill to 60 mph in 4.3 seconds and turns the quarter-mile in 12.7 seconds at 113 mph The E46 3-Series suffered from a design flaw in which the mounting points for the rear subframe would crack or tear over time, causing some serious damage to the chassis if left untreated.

When I installed it I didnt have the tabs, that go under the rear top flap, properly alligned. When the top flap went to close, I heard a two clicking sounds and the system quit working. It met some resistance. Here are the most common issues with the top listed by symptoms to make them easier to find. Red light blinking. The red light blinking indicates the CVM (convertible module) has stored a fault code and locked out operation of the stop.

One of the most common problems I see on the 330 is that it causes the owner to do random and unnecessary fix and maintenance to it using cheap or ebay parts, resulting in it breaking in the process.

Sometimes it can clear if you restart it a couple times. If it doesnt clear you'll need to go to a dealership/independent shop to clear it out. EWS is BMW's 'brand' for their immobilizer systems. E39's have version 3.3. There is an "EWS Module" that is the brains of the system, however it talks to other parts of the car as well. DME is BMW speak for the engine computer aka ECU in generic car-world. DMZ is "Demilitarized Zone". It is irrelevant to this conversation. g88aI.
