Eng replacement
I have an 07 A6 with 29K miles on it that has piston slap. Would you leave it alone or let the dealer replace the engine under warranty? Would the new engine reduce the value of the car?

I would let the dealer replace it if they are actually willing. Most dealers will say its normal.
As far as value...its a dime a dozen car so I wouldnt give it much of a thought....JMO.

I'd be willing to bet GM won't approve an engine replace under warranty for piston slap.
LS motors are kinda known for it in the first place and I don't think there's any evidence it shortens the life of the motor (as long as it goes away once things warm up a bit)

And I agree and also doubt that GM is going to authorize a new engine for piston slap. Whether the dealership is busy or not is irrelevant. They are not part of the decision process. They will be required to send the old engine back to GM for inspection, so they can't even exaggerate the problem in order to help you out.

Our 2001 Tahoe has suffered from piston slap for all of it's 73,000 mile life, hasn't hurt a thing. The knocking sound goes away totally in a minute or two.
