Electric windows will not shut
Given that the electric windows in BMW cars frequently break down, causing them to stay open! This particular problem is not just one of comfort, but also of security. After all, if you can’t securely close your car’s window, then what’s to stop someone else from forcing it open? Given that BMW cars among the most stolen in many parts of the world, owners will want to fix this problem quickly to keep their pride and joy safe from prospective thieves.
Problems with heater core
The car’s coolant system and heater core are closely related, so it is hardly surprising that they both have problems with regular failures.
In fact, issues with the car’s internal heating system – either over-heating or not producing enough heat – can sometimes be the first clue that there the engine’s coolant system is about to require service.
The other clue is an unusual sweet smell coming from your heating system; this is the coolant, and when it starts to leak, it can soon find its way into the heater core.
Issues with fuel pump
Owners of some of the most popular BMW models have reported issues with the high-pressure fuel pump, which can cause poor acceleration, engine stuttering at high speed or even a failure of the engine to turn over at all.
All engines have two fuel pumps, the low-pressure pump which takes gas out of the tank, and the high-pressure pump which pushes the gasoline into the combustion chamber.
If the high-pressure fuel pump in your BMW is performing below par, the only solution is to fix it, which is not a cheap repair if the car is out of warranty.
BMW cars seem to be afflicted with more than their fair share of dead batteries.
The first clue that this may have happened to your car is that you can’t unlock it; the BMW’s central locking system runs off the battery, so you may have to use the manual key to even gain access to your vehicle!
Luckily, it is pretty easy to jump-start a BMW from another car – it is just annoying if you find that you are having to jump start your car once every few weeks.
