Are you looking how much oil you need to add to your BMW engine after an oil change? Here is a table with most filling quantities separated by older models like the E30s, the E32 and E31 and a table with the newer models starting at the E36s and E39s all the way up to the new E92s. Always use the proper oil level checking procedures for your car. The oil level should register on the dipstick about two thirds or higher between the Min and Max markings on the dipstick.
The S54 and S62 engines require the engine to be at operating temperature when checking the oil level also you will need to have the engine idle for at least 15 seconds andwait one minute for the oil to drain back down then check the oil.
The new NG6, N62TU and the S85 engines have an electronic oil level check. Please see the manual for the correct checking procedures.
This Technical Service Bulletin is regarding A/C Blower Motor/Regulator Malfunctions in BMW E46 3-Series and E83 X3 vehicles. The vehicle seems to have a faulty blower regulator right after the A/C control panel is replaced. The disconnect of the 18 pin connector from the A/C control panel within 15 minutes after turning the engine off (run-on period) will send a voltage spike to the blower regulator temporarily disabling it.
In this situation the blower regulator will will not necessary have to be replaced. It can be reactivated by pulling the fuse 50 which resets the blower motor. If resetting the blower motor does not reactivate the regulator, the part will have to be replaced. BMW does currently not allow the use of the blower regulator 64.11.6.923.204 which used to be made by Sitronic and distributed by Valeo, but recommends to use the latest version of the regulator. To avoid this problem in the future disconnect the terminal 30. This will prevent voltage spikes in the blower regulator when disconnecting the A/C control panel.
Certain BMW 335i and 335iA (E92) will develop a refrigerant leak from the pressure line from the compressor to the condenser due to vibration. The problem generally occurs in vehicles built between 5-15-2006 and 8-10-2006 or the following chassis numbers: 335i PV80025 - PV80659 and 335iA PV82032 - PV82955. The chassis number and built date is not the only deciding factor. To see if the Technical Service bulletin applies to your vehicle you will have to check with your dealer.
The repair procedure is fairly simple after removing a left side charge air duct, a bracket needs to be attached to the pressure line and mounted to the compressor using two M5×12 screws. Then reinstall the charge air duct.
This repair should be done under warranty. If you purchased a used vehicle you should check for a round service sticker on the B-pillar. If you have around service label with code 476 punched out the repair was already done.
