Coolant leak - Culprit is the Coolant inlet valve seal

[Nemo78]

Well looks like I have the coolant issue also - third time in 3 months I’ve had the warning - car is booked in so let’s see what the outcome is...

Andy/Crasher have you come across anything new on TPIs?

Oh dear, hope they sort it out for you mate, mine was a replacement coolant inlet valve.

Thanks

Did they diagnose it nice and easy?

Here is a pic from this morning

Originally they said it was the coolant seal, when they probed into it the said it was the valve. So the seal is not covered under Audi extended warranty but the valve is. Mine was just out of manufacturers warranty. It was done under the extended warranty.

Just to keep thread updated - shut off coolant valve replaced - visible to see that coolant had leaked so diagnosis was simple

Good result, keep an eye on the level for a few weeks, mine dropped after the valve replacement which was blamed on a air pockets so required topping up. Been watching it for a while and all seems well.

That is what we int trade like know as “burping”, a bit of a conundrum. Do you keep the car overnight so it cools and “burps” but **** off the owner who MUST collect the fruits of their loins from school in something the size of a mid WWII tank, or send it out at 2.30 in time for the school crawl and hope the thing is burp free and does not drop a smidge and set the bloody warning light off.... if only everything in life was so easy as flying a desk......

Same problem here. Coolant valve located under intake manifold.

Same problem here; just fixed last week. See other thread from me. Under extended warranty. Needed a couple of coolant top ups for the ‘burps’.

Same issue with mine - dropping about half a litre every 4 weeks. Audi traced it to the coolant shut off valve and as it’s an approved used car their extended warranty will cover it. The original warranty lapsed 3 weeks ago so lucky to have the extended, although that runs out in November...
in fairness to the dealers they were pretty good about agreeing to it under warranty. I thought I’d have a fight on my hands.
