Re: Coolant leak - Culprit is the Coolant inlet valve seal
I noticed collar level drop on m Q7 with 53000mls.
Got Audi Dealer to diagnose the issue while the car was in service.
I have RAC warranty, but they rejected the claim because Audi sent them the service Bulletin, which states that this is an gradual failure of the shut off valve and not an Sudden failure.
So on that basis, my Warranty claim got rejected, my warranty apparently cover everything on car which fail suddenly!! Typical warranty response!!!
Now I will have to pay for it myself, but will get it done at a specialist rather than Audi ********!!
I’m going to send Audi UK email asking for contribution towards repair…probably won’t get any but worth a try.
Any suggestions, how to handle Audi UK?
Re: Coolant leak - Culprit is the Coolant inlet valve seal
Nearly all aftermarket warranties are useless as they are "mechanical breakdown" and specifically preclude "wear and tear" so read the small print. RAC warranties used to be the best but they offloaded the division to a third party and now they play the same dirty tricks as the rest of them, it is a market place that really could do with some tighter legislation as it is a party place for those of a nefarious mind.
Re: Coolant leak - Culprit is the Coolant inlet valve seal
We have another 4M in today with the CRTC engine and a coolant leak. Nottingham Audi have diagnosed the coolant shut off valve and quoted something like £2500 to replace it :eek: I took the lower covers off and they were soaked with coolant but on the engine the only trace of coolant was tiny around the oil pressure valve and cover corner, not a trace further up. I pressurised the system at 1 Bar for an hour and nothing showed, I ran it for two hours, nothing... where it had shown a trace of a leak remained dry. I put the endoscope down in the V and it looks dry and no pink G13 traces. Where is has dripped onto the oil pressure valve looks to be coming from the front cover but I think I am going to have to strip the top down and take a closer look but it could be eight hours down the drain.

Re: Coolant leak - Culprit is the Coolant inlet valve seal
If it was soaked in coolant, it’s likley one of the hoses are leaking. 2 years after my repair, one evening, after putting the power down, I lost all my coolant in one go.
Turns out the muppets at farnborough Audi hadn’t put one of the hoses on properly, the jubilee clip wasn’t over the ridge, and over time it has worked it’s way off. Anyway I found out by adding coolant which was gushing straight out, I stuck a £20 camera down the engine bay, and discovered one of the flexible hoses was off the metal hose connection, reattached this and it’s been fine since.

I have had it under 1 Bar pressure with a pressure tester for an hour and then engine running for two hours at fast idle, not a sign of a drip, the engine valley looks clean using an endoscope, with the amount the car was losing I would expect the smell of coolant and in this temperature, a wisp of steam but nothing!!

Hello all this is happening to me this past week, I can’t seem to find the TSB anywhere in search!

I think that link disappeared for whatever reason. There's no clear searchable source of Audi TSB. This is the best I can find.
