The leak suddenly got worse. See the photo - looks like the o-ring joint is leaking and coolant runs down the end of the matrix. But the screw is tight. I guess I’ll take the joint apart and see what’s wrong. Does the joint look OK and correctly settled in place? Or is that top pipe not quite in place? Maybe the o-rings are duff - perhaps I should fit fatter ones….
Hard to measure the old ones if they're naff, maybe someone knows the specs

Duff O rings or maybe the 2 halves of the joint are slightly misaligned?

The old ones were perished, hard, and broke when removed. I fitted new Britpart ones, bought off ebay, what could possibly go wrong…

You previously mentioned fatter ones - do you have the spec perchance? While I have the joint apart, may as well fit the best…

Sorry, no I don't, my O rings came from Island 4 x 4 for both cars and have been trouble free now for a long time. Hope that hasn't jinxed it

Mine are Allmakes from Wick 4x4, long term eBay dealer, so should be OK. I’ll check alignment and see if that’s the problem. Loosen screw, wiggle joint, the usual procedure.

I ga
I gave the O rings a coat of silicone grease when I did mine.

Am not getting anywhere with this - the leak gets worse and worse. Different o-rings, same result. Photo of original (replacement) rings attached - they look different sizes but that’s just the photo. As soon as I start the engine, coolant drips from the joint area. All looks nice and level, see photo, coolant around head of Allen bolt - how did it get there? I am wondering if there is a crack in the manifold that the pipes fit into. UV dye on order, maybe that will show it.

I wonder if the bolt has been overtightened if it has distorted the assembly? Looks like you may end up with a matrix replacement job.

Could be - I tightened to 3Nm when it started to leak, but prior to that it was at 2.2 Nm, which is not much.. To put it in perspective, RR Rave lists it at 5Nm. As you say, looks like an Audi matrix upgrade and no more O-ring problems.

That's tough, big job, guess I was lucky with both mine.

I’ll fit a u bend, get a little electric heater, wear my sheepskin pilot jacket, good gloves, and pray for warmer weather!
Not this week sadly ...

Can allegedly be done without removing the dash, just need to do some cutting - Paulp38a.com is a very useful information source…. As I have panels and ducts removed for the o-ring job, I am already halfway there.
