Hey guys newcomer here. I have a problem and was wondering if anyone could help. My headlights flicker then turn off but a moment later they will c9me back on. Then every now and then one headlight will stay on and one will turn off any ideas why? The headlight bulbs are fine as they were changed last month for mot.

Morning Ben

Welcome to the Forum

Did they flicker and mess around before the change of Bulb? Are your Lamps Halogen or Xenon ?

First I would check the simple things are there any loose connections anywhere plus check the earth connection are good and there is no corrosion anywhere.

If all connections are clean and the lamps are Halogen then check the switch. If they are Xenon then also check The Xenon control unit take care as this unit holds a high voltage discharge so if you don't know what your about get someone who does to help.

Finally, it could be a fault with the FCM/LCM (Footwell control Module/Light control Module) The best action here will be a Diagnostic Scan using a GOOD BMW capable system preferably ISTA/INPA or similar

      X3 2.0 automatic

      hi , I had very similar problem a while back, and after a lot of testing with vista, it turned out to be a front R/H wheel , speed/wheel sensor. when it all was happing lots of codes were coming up gearbox, diff front and back, transever box,plus many more, didn't look good, but there was one code that repeatedly came up at the top of the list, at this point it was becoming undriveable ,it just didn't seem that a wheel sensor could cause all these codes. So I went got two wheel speed sensor, replaced driver side front, the problem never came back, the sensor controls so many systems ,cleared all codes, happy days, I could have pulled the car apart for nothing, and got nowhere, except an empty wallet. hope this helps you or someone.

      105C thermostat replacement

      As I understand the wiring diagrams and operation Item 9 on the thermostat housing is the sensor which sends its signal to the ECU for interpretation with information from the map sensor. Information from item 12 (1st drawing ) is also used to provide average temp across the cooling system. As far as I am aware the Thermostst is independent of the sensors and operated by expanding wax material internally

      BMW 318i boot locked can’t get into

      Errr not clear here Donald Plastic "L's" with short rubber hoses ??? Distilled water/Ionised water should only be used in an old style lead acid battery. The Rad and engine coolining system should be filled with the correct coolant mix to prevent cavitation and the danger of freezing in low temps. Coolant should be part of the cars regular maintenance and changed every 3 years or so. At that time all hoses and connectors should be inspected and changed where necessary to keep everything in tip top condition. Changing parts can cause as many problems as you may think your solving

      BMW 318i boot locked can’t get into

      Update: I checked my battery and it charged in 5 minutes, so I don't have to find another alternator. All seems to be OK except for the plastic "L"s with a short rubber hose that bypass the HV/AC solenoid. Those get clogged after @ 150,000-190,000 miles (if distilled water wasn't used) and cause air pockets that try to burst radiators. I have a few more brass "L"s, so now I can throw the plastic ones away. I have to be careful I don't fog the windows though, without heat or cool.
