I wasn't sure what was causing the apparent overheating, sitting in traffic. After I used this the overheating stopped for sure. This BMW copy Radiator exp tank cap works ok, but does not fit as well as the original. I have ordered a genuine BMW cap from the arrogant chaps at the local BMW garage though. As always, you get what you pay for, in my case twice.
