Good afternoon all...
Yet another perfect solution found on this forum
Yesterday I started up my K12 for my journey home from work, having left her idling for 10-15 minutes I returned to find that she had wet herself....Poor girl, there she was with a damp patch about a foot in diameter right between her wheels.
I lifted the seat and almost got a blast from the super soaker nozzle on the expansion tank, what the buggery was causing that I thought !!
So, i took the gamble that once riding she would calm down and get me home(130 miles ) and she did... However, when I went out on her later yesterday, oh she wasn't a happy girl at all, temperature was a rising, fans were constantly on and she was having a hissy fit underneath my seat.
I got home and flicked on the Lappy and straight into this forum, and there were a couple of scenarios but the diagnosis that fitted the problem was quite simple....
Replace the ~ Radiator Cap
As BMW parts are closed here on Sundays I had to find a temporary replacement.. BMW caps are 1.5 bar but all I could find was a 0.9 bar. So, off I went home and fitted it to the radiator, and hey presto... no more gushing expansion bottle !!
I shall get a 1.5 bar asap
Thanks you all out there for yet another perfect fix !!
