SOURCE: doors on 2007 BMW 328i will not unlock

hey solo, 06-07 door lock actuators can blow a fuse in the glove box. bmw does have a specific bulletin that addresses this issue and requires replacing the fuse if blown and measure the resistance of all the door lock actuators to determine which is bad. the doors should be able to be opened with the key mechanically. if not for some reason, you should be able to comfort open the windows and will have to crawl inside the car. the fuse panel is inside the glove box and not fun to get to. I believe the fuse is a 10 or 15 amp fuse maybe 5th from the bottem right.

I suggest you to check fuse # 57 15Amp at juction box, you can access it from glove box. if the fuse is blown, replace it with 20A and try to operates lock/unlock 10X and replce door lock fails to responce during the operation. dont operate lock/unlock 15X the system will stop and you have to wait for few min to function it again.

SOURCE: What does the big red

If this model has the runflat tyres, it could mean that the system has detected a punture or low tyre pressure. Check the pressure of all the tyres, and reset the system when the fault is rectified. The reset procedure is in the owners manual. Hope this helps.

SOURCE: hi i hava two code

Hello,

P0491 is a Secondary Air System fault Bank 1.

Bank 1 refers to the passenger side off the engine. The combination valve for secondary air injection did not preform as it should & set a fault. The valve is located under the plastic engine cover at the rear of the right cylinder head.

There is a plastic tube from the air pump to the valve that breaks, the valve sometimes fails, there is a vacuum hose that opens the valve that also sometimes fails & rarely the Air Injection Vacuum Control Solenoid Valve fails. The plastic tube unpluged/cracked or failed valve are the 2 most common failures.

If it's a vac leak it's in the small hose from the solenoid valve to the combination valve. The super charger may affect the vacuum, but I would expect to see more codes if it was really messing with things. The air injection system only runs for about 1.5 minutes on cold starts. If the plastic tube is broken you will hear what sound like a small exhaust leak.

P0410

What does that mean?

The P0410 code refers to the emissions system. The AIR pump puts air to the exhaust to lower emissions. It takes in outside air and pumps it through two one-way check valves into each bank of the exhaust.

About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.
Symptoms

Possibly symptoms include:

* MIL illumination obviously
* Hesitation on acceleration
* Noise from a bad/stuck AIR pump

Causes

A code P0410 may mean that one or more of the following has happened:

* Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump
* Blown AIR pump fuse due to freezing up

Possible Solutions

Note: There is a technical service bulletin (TSB) regarding this code for a number of GM models. The TSB calls for the replacement of the AIR pump and the installation of a new secondary injection hose.

Additionally, if you simply replace the AIR pump the problem may return again (and again). If you replace the pump, also clean out the hoses and replace the one-way check valve. In a few cases, people have put a small hole in the rubber cover on the pump which allows any water to drain out.

Also, please note that this may be covered under the emissions warranty on the vehicle. If your vehicle is out of bumper-to-bumper warranty, check if the emissions warranty is still valid!

* Replace the AIR pump AND one-way check valve
* Test and clean the AIR pump AND test and replace the one-way air check valve
* Replace the AIR pump inlet hose
* Replace the AIR pump fuse (found under the hood)

The above are the interpretation of the codes.

Let me know if you need further assistance.

Regards.

If the temperature control is on cool....sounds like you have other problems with AC. ( compressor not working, needs R134,) Check under the hood for a box that has fuses in it, their are also relays in it. Look for the relay marked AC.

2007 BMW 328i back driver window is not rolling up, help?


It's probably the window regulator, common problem in BMW.
It's not hard to replace, but if not mechanically inclined, better to take to a dealer or your independent BMW technician, the part is not terribly
expensive (for a BMW)but labor might run into some $$ at the dealer.
