There are two campaigns, and one campaign should cover two valves.

Yea. Just take it in and they'll replace the two valves. I'm still amazed that they wanted over $25 labor to remove one (1) highly accessible screw and pop a license plate bulb in. I'd be very surprised if It took more than 3 min. If I wasn't so shocked and perturbed , I'd be embarrassed and ashamed for them.
Good thing the recall was covered, otherwise I'm guessing $700 or more
I feel sorry for women with these higher end cars. I can only imagine how they're robbed and taken advantage of.
One dealer, bulb is $4.95, the closest to me is $5.28.

I took my A8 in for 80B8 and 80B9 recall notices I received from Audi. The dealer called me to say I need a coolant flush service because the coolant is dirty. The service will cost $200. So my question is don't they have to drain and refill the coolant anyway in order to replace the shut-off valves?
Please help answer this question as I don't want to pay $200 if I don't have to. Thanks

No they wouldn't have to drain and refill the coolant to replace the valves. They might loose a little but that would just require a top off.

Has anyone ever heard of this happening before?

Same valve just leaked on my 2013 TTRS, connector smoked so it's going to be a bit more difficult to deal with.

The idea is to cable tie the drain part lower than the solenoid or connectors.





















Where did you order those plugs, I am having trouble getting the correct plug and wires, the first set of wires I ordered didn't have the correct connector on them...

You do realize that you are replying to an 8+ year old post, right? The poster hasn't even been on the board for 4 years. He probably doesn't even have the car anymore.
.
That said, you might try adding information about your car, so anyone trying to help will have something to go on.
