BMW Repair Questions? Ask a Mechanic for Answers ASAP
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.
I hope this answers your question but do please feel free to ask any further details by replying to this thread.
Can I answer any further details for you.
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.
Ok, I will be on again tommorow if you need any further help, just reply to this thread.
