Don't laugh but as I first stated I had a small coolant leak toward the back of my engine. I thought the dreaded curse of the coolant pipe had hit. But after I fixed the heater control valve no more leak.
Can it be? Could the valve cause the pressures in certain areas to go high and leak? Very interesting? I looked at the hoses while doing the replacement and one hose was bone dry. What do you guys think???
Hi I do not know how to do it but you should consider putting this in the DIY section, as it is an excellent bit of fault-finding to benefit others!!!

Always said I would go back to a 6 series
