2001 BMW 330 - Answered Questions & Fixed issues


First suggestion, ensure the AC is properly charged... the AC system is very picky... so check belts pulleys and AC charge first... if the AC is healthy and this issue is still present... you have two possible solutions...1. heater control box in dash behind the radio...Expensive part $450+ and lots of labor to pull dash apart... or 2. the heater control valve in the engine bay... $130 part you can do IF you take your time

wether it's worth the cost of repair is something only you can decide, what is the mileage and condition of vehicle ? have you had the OBD codes read to see if there is a code to help with diagnosing the problem ?

Thermal issue is shutting down amps till temps moderate. You must be driving your system too hard. And check out your tone control settings especially the bass. Every 3 db boost forces amp to double power at that frequency so if you are already blasting at 100 watts, a 3 db boost will compel amp to put out 200 watts, etc. Very easy to overdrive and overheat amp. You might want to try blowing air over output stages to improve cooling at high volume levels.

You are lucky that you have good protection circuits - otherwise by now you would have blown the output stages.

Have you checked the fuse panel for blown fuses? If not, start there and let us know if you do or don't find any.

Per Tire Rack, for a 2001 330ci you could use 235/35-19 front and 245/35-19 in the rear. Wider tires for the same profile increase the tire's effective diameter(think wheel well gap above the tire) and will change both the odometer and speedometer readings. Additionally, the wider tires may cause rubbing of the fender or other components while turning unless the fenders are flared out.
Caliper clearance should be checked, usually M3 uses bigger calipers than stock. While they may look cool installed, there are several disadvantages to lolwer profile tires such as harsh ride, unforgiving of potholes/speedbumps, wider width is worse for snow application (cause that floating feeling). The 2008 wheel will have the tire pressure monitoring system (TPMS) .
Both have a bolt pattern of 5-120.

You need to have the dealer do some testing with a special system scanner.

Sounds like you have a bad ignition switch. Replace it and it's likely your problem will go away.

can you be anymore specific ,symptoms and why you think its that

BMW recommends you use Mobil 1 (5w 40) or (5w 30). If you live in a very hot climate use 5w 40, if not, use 5w 30 or alternate between the two viscosities each season. Ultimately, you would be ok using 5w30 in North Dakota year-round, and 5w40 in Texas year-round, you just might notice a small decrease in performance during extreme weather.
