#2433 of 2734 BMW 530i 2004 water leak!!
Dec 20, 2009 (4:03 pm)
OK, Had a major leak in my car, if I left car in rain the rear passenger side foot well would fill up with water (over 2'' + deep) the issue is that it took BMW service forever to fix it in that time it fill with water several time. Found out the it was coming in from the heater box and rolling in under the carpet so who know how long it was going on!! With all the electrical that is in the area should I maybe just ell the car to get rid of a potential issue long term with the electrical going bad from all the moisture?!?!?!?!?!?!?!??!??!

Water or coolant. If water, from the heater box, that was probably clogged drainage in the fresh air vents (situated under the wiper blades). Wires are wrapped up pretty well so I wouldn't worry, unless it dripped on some component...but usually what this type of leak does is drip along the inner firewall. I don't think I'd worry about it. I'd be more concerned for the power seats I guess.

Are BMW driveshaft still not rebuildable?
Some aftermarket shops rebuild them as does BMW.

It was water, it migrated fom under heater under the carpet to the lowest spot on the car which was the back seat footwell. When the water was in the back it did cause all sorts of electrical items to go off, i.e. active steering said it was not communicating, stereo was weird, seat would not work, etc...all the water is now gone and all communication seems to be ok. The worry I have is the corrosion going to continue to wires in the area....

Ah well, the great mystery. I don't know what to say. I can only give you some solace, in a weird comparison to my laptop computer. I dumped a large cup of coffee on it, and of course, it shorted out, etc---but once we took it apart and cleaned it, it's been fine.
#2438 of 2734 Replaced Fuel Pump/ Ignition Coil?
Dec 21, 2009 (7:28 pm)
While researching the 5 series E60, I've noticed that there was an issue with the high pressure fuel pump or the ignition coil on numerous vehicles. I would like to know if anyone has experienced the problem, and how their cars are performing after the replacement, please.

The HPFP issue only affects cars with the N54 engine.

my preliminary research outcome is that the faulty N54 engine were in cars until March 2008. I wonder when BMW started to manfacture the 2009's? Just wanted to ask anyone who experienced the failed fuel pumps and how their cars are performing after they were changed out.
#2441 of 2734 Lower Gas Mileage Lately - Why?
Dec 24, 2009 (9:45 am)
I've been reading these boards for over a year now, and have gotten terrific information, many thanks to you all for that help.
I have a CPO 2007 530i with 28K on it. Vehicle has premium, cold, Sports, prem. sound, NAV. Love the car. Really terrific. Since I got the vehicle in June 2009, I was consistently getting like 20mpg city driving, consistently. Verified by myself each time I filled. Now, all of a sudden, I notice I'm getting less mileage. It's down to about 17mpg, with the same type driving. I am very light on the foot, and always let the car coast, and use cruise control when on the highway. I dont' have a heavy foot at all.
What could have changed? Is it the cold weather (live in CT). I just don't get it.
I was getting like 300miles on 15 gals every time, like clockwork. Now, I'm getting maybe 260-270 miles. I'm about ready to call the dealer, since the car is under warranty until June 2012, but I figured I'd ask here first.
Anyone have a clue? Thanks guys, and Merry Christmas and happy New Year!

That is probably normal. The factors working against you are:
1. Friction -- all the fluids and greases in your car's rolling hardware are thicker, and require more energy to overcome and get warm.
2. Tire pressure--it will drop 1-2 lbs in cold weather---again, more rolling resistance
3. Driving habits -- if you sit and think about it, you probably are making more short trips where before you would walk, due to the cold weather.
4. Warm-ups -- your engine management system is designed (mapped) for optimum engine temperature, and is less efficient when the engine is cold.
You might consider an engine heater when you park overnight, and inflating or at least checking your tire pressure just a little bit more.
