Customer: yes I just want to flush out normal water and replace it with anti freeze but I don't know how many litters I need
Customer: also theres a cable from aircleaner whenever I plug it the just cut out or sound funny but when I unplug it runs okay


thank you for your question, my name is ***** ***** I am a fully qualified vehicle technician with over thirty years in the trade, hopefully i can help you.

The total capacity of the cooling system on your BMW is 9.5 litres, the recommended mix is 50% so the antifreeze needed for the system would be 4.75 litres.

The recommended coolant is listed as longlife blue.

The cable from the air cleaner may be the ambient temperature sensor, if this is faulty this will affect the running, unplugging it revert the system to a set parameter.


Many Thanks

how do I solve sensor issue

It is recommended to use distilled or deionised water to mix with the antifreeze, this assists the anti corrosive properties. It is available in Halfords and similar outlets.

The sensor will need to be checked using an EOBD scanner to locate the problem, once the scanner is plugged in it should retrieve a code to identify the problem. If this determns the sensor to be at fault it will need to be changed.
