Also, if I’m not mistaken the 540 in particular uses the inter cooler as part of its AC loop, isn’t this correct?
Perhaps somebody more knowledgeable can chime in. Fact is that a lot of the b58 engines are known to consume coolant, with none of the typical symptoms of coolant entering the combustion loop (white smoke and the like).
Still worrying though. I’m monitoring my coolant level and it is sinking, albeit very slowly.
Will try and take a picture one month from when the coolant was refilled.
It would also be helpful if the other members who have had coolant issues and topped up can report on subsequent coolant levels..

I had mine topped up at around 3,700 miles, pressure tested etc and no problems were found. Since then (approx. 1,700 miles) I have noticed that the level has gone down a tiny bit - if it continues to drop then I would assume that it would reach the min mark in about another 6-7000 miles. So it does appear to be losing a very small amount of liquid out of the system over time. Really really odd! Guess the car is like me - likes a bit of a drink!!
No symptoms of any kind of problem, oil filler cap has no gunge / sludge on it, no smell from exhaust, nothing... Answers on a postcard to ...!
