We had a random coolant level low warning come up yesterday, after already having done a 15min short trip somewhere. Left car for 2hrs and come back to it to drive home. Would like to top it up before driving again, reservoir looks really low. There seems to be red coolant colour in the expansion tank, what should I add to get me to a garage for flush/change etc? Thanks

Hi all, will introduce myself proper when I get the car back from the Mrs and take some photos etc. We recently picked up a white 2013 116i Sport, and am already keen on tuning it. This is a second family car, used as a run-a-bout but not a daily. Would like to take it to my mechanic for health check prior to tuning. But my question, after a quick search, has anyone done any DIY tuning with the affordable gear I've seen online from AliExpress? Is it a case of buying a programmer, removing ECU, downloading a file and writing it into the system? Is it worth $1000+ to get it done professionally versus trying to do something for 2-300? Thanks
