Just a quick question: Since most of BMW cars are rear wheel drive, are those two rear tires consumed more than front one? Thus, should tire rotation performed every 5000 miles? Thanks for the advise!

That said tires should be inspected regularly for signs of poor wear or misalignment. In the past, BMWs had a tendency to wear tires on the outer edges, particularly the rears.

| I just purchased a BMW 528i. A couple of issues have arisen with this car. First, I believe there is a problem with the thermostat. It takes forever to heat up when I drive it short distances, but on the highway it heats up fast. Secondly, it run rough for a few minutes when iI first start it, after it has ran a few minutes, it runs perfect. Also, I noticed it has strong exhaust oder when running rough. Thirdly, the wiper fluid is not coming out of the wipers, should I hear the pump running and if I dont could it just be a fuse? Or it needs a new pump? I was wondering what the cost would be to fix these problems if I need to take it in for repairs? | |

Replying to: someblueflower (Nov 17, 2009 5:23 pm) As for the strong exhaust odor, it sounds like your plugs are fouling on start up---either due to a dripping injector, or leaking valve stem seals. Do you burn some oil, or you don't know yet? Probably the pump is shot, another typical problem. You can test the pump with some wires off your battery or putting a test light on the connections and flipping the switch.

Replying to: someblueflower (Nov 17, 2009 5:23 pm) even in winter driving. That's a cheap fix and so is a replacement wiper motor but check the fuse first. Don't know why yours runs rough on startup, perhaps the EFI isn't making the mixture rich enough, could be a bad sensor or bad coil. If the odor you're getting is sulfurous, you might have a plugged catalytic converter.

Replying to: someblueflower (Nov 18, 2009 5:48 pm) So you start up first thing in the morning, and your spark plug momentarily fouls due to the oil on it, and you'll get a few puffs of blue smoke. Once the engine runs for 30 seconds or so, it smooths out and the smoke disappears, because the oil has burned up. Can oil still drip from the valve stems while you are running around town? Yes but only under conditions of "high vacuum", which generally means letting off the gas while in gear and letting the engine drag the car's speed down---then, when you step on the gas again,----POOF!---another quick burst of smoke.
