All seems well and on popping the bonnet on return coolant levels were fine, risen a bit due to heat expansion.

I'll check again when the engine has cooled; I wasn't brave enough (this time) to loosen the coolant cap to see if it was holding pressure.
Just checked this morning and cold levels are back to where I topped up to. No signs anywhere of leaks.
Dare I risk a 200-mile round trip on Thursday...….

Mine had a leak like that for a couple of years at one time. It would seemingly lose coolant randomly, or whenever I wasn't watching it. When I remembered to check it, it never seemed to go down. Then I'd forget to check it for a week or two, only to find that expansion tank was down below minimum again. I drove it for thousands of miles like that, with a small (concentrated) bottle of coolant inside the spare wheel for emergency top-ups.

In my case it turned out to be the radiator. When it went in for a major service the garage spotted a small hole in it that was slowly weeping coolant. They fitted a new radiator and I've had no loss of coolant since.

The warning reappeared this morning, though I haven't checked in ages so don't know whether it's been slowly dropping or only when driven.
That's 5 months of low use, probably less than 500 miles. On 101773 now.

Again, took about 750ml to top up, this time the correct 50:50 mix.

So, I definitely need to call in an MJs after the annual meet to get it checked, assuming it gets there OK.

I'd hazard a guess that it's the classic oil cooler plastic union/part that cracks, as the symptoms mirror my experience of coolant loss. Mine was replaced with the revised aluminium part when DS Autowerks changed the cam belt last year.

Could be that I guess, no obvious signs of any leaks but I'm no expert!
If it is that what are the chances of a catastrophic failure?

I thought it was an engine out job to replace, or did DS know a clever method?

The plastic pipe won't fail catastrophically because it is constrained by the oil cooler housing.

It is possible to change it with the engine in if you are determined enough. Its just not a pleasant job because of limited access, although its much easier with the front end off. I'll change it as a matter of course on an engine-out service, but I wouldn't take the engine out if that was the only job.

That's good news, thanks.

I do actually have a version of that pipe as a spare, bought some time ago from Poland and made of brass I think. I carry it as an emergency backup.
But if that's the problem, and you end up fixing it, do use your own preferred version.

I had a number of slow leaks on S8 over the time. The one that keeps coming back is the small pipe on the expansion tank breaking, I think I have already replaced tank 3 times and it's broken again.

New Meyle tank arrived this morning and this time i put some epoxy putty around it to reinforce and relive some of the stress. Also used primer/activator/adhesion promoter from loctite palstic super glue kit as epoxy does not normally stick too well to plastic on it's own and I have used this primer with epoxy before and achieved good resuls. http://www.loctite-consumer.co.uk/en...-plastics.html
