BMW 320i Parts & Accessories

I got myself a used BMW 320i and I must say I'm generally happy with it. However, I've been encountering this erratic flashing of the engine management light. It would come on and off and is becoming a distraction. I don't usually have time to spare to have it checked by the dealer. Is this something to worry about?

The flashing of the engine management light is something you must take seriously as it is well, a warning. There could be several reasons behind its erratic behavior, which when left unchecked, could cause serious damage both to you and your vehicle. Once you see it flashing, the first thing to do is have it diagnosed as soon as possible. It could be that the system itself is faulty, or there could be some glitches with the oxygen sensor andthe emission control. The fuses also are probably blown out, or the relay switches got loose or broken wires. Make it a point to have these components checked only by a reliable professional who knows the electrics of your BMW so well.

The front passenger door of my BMW 320i is stuck shut. I could not open it whether from inside or outside. Help!

First of all, is the door lock working? Have you tried locking and unlocking it? If you have tried this basic troubleshooting procedure but still your door won't budge, then the problem might be inside the door locking mechanism itself. That would mean having to pull off the door panel. Dirt that accumulates inside the lock could get in between the springs and eventually absorb water. The onset of the cold weather doesn't help either as the combination of dirt and water causes the springs and wafers to freeze. Another problem could be the lack of lubrication. Using the recommended BMW lubricating product on the gears would restore the pushing and pulling mechanism of the system. Taking your BMW 320i to your authorized dealer could save you from a bad day since they would be able to detect the actual problem and provide you with immediate resolution.

I could not get my wipers to move so I had a hard time driving home one rainy night. What must be causing it to get stuck?

Your windshield wipers are one of the safety devices of your car. Hence, it causes enough trouble whenever it malfunctions. There could be two reasons your wipers are dysfunctional—it could either be a mechanical problem or an electrical issue. A blown out car fuse would not send the right signal to the motor. When replacing it, make sure you use the precise ampere rating required for your car or else the fuse would always blow out. Another thing to look into is the wiring connections to see if they are loose, short, or broken. You may refer to your car manual for the proper wiper assembly circuit diagram. It could also be caused by a defective motor, which leads to inadequate power supply. If such is the case, you would have to replace it with a new one. Since the mechanism itself can be quite complicated, it is always best to seek the help of a professional mechanic who knows your BMW well.
