general problems of the 2004 BMW M3

Faulty smg pump possibly caused by a culmination of other failing parts in smg system. Car is rendered inoperable in potentially hazardous driving situations that would otherwise be circumvented by a system more capable of warning the owner of an impending failure. The remedy the majority of dealerships are using are replacement of the entire smg system, which costs up to $7,000. 00. As hidious as this sounds, there more than likely is a very small factor or part that is causing the entire system to fail. BMW needs to address this immediately.

This is the second time this happened to my car the smg (sequential manual gear) light comes on and then my service engine light comes on as well every time in that order , also my car shifts itself into neutral all on its own and I can,t control the acceleration on the highway or anywhere else so the car begins top slow down, many people have addressed this issue to BMW n. A. And nothing and it only happens during hot weather, and BMW ran a diagnostic on my car and they gave me multiple things that can cause it so they expext me to pay for all of them even if they are not all the culprits. This is a very dangerous issue especially on the highway and I have kids so it makes me even more worried that something might happen because of this and BMW's negligence to the issue.

Automatic transmission smg hydraulic pump failed.
