Gunner 0 Report post Posted December 12, 2010 Hey everyone, I recently sold my E36 320i and now looking at getting a e46. Looked at a e46 318i (just gna get b a daily driver) which was quite tidy except the coolant light was on. I've read on the internet that it could be mainly 2 things. 1. either coolant level is low. 2. sensor in the expansion tank could be faulty. it didn't appear to be leaking any coolant but is there any other main things it could be? also is it a expensive fix? Cheers Quote Share this post Link to post Share on other sites
