Water pump Cause loss of engine power?
my water pump seems to be going in and out. sometime it makes a rattling noise and power in the engine is noticeably less. when the rattling goes away power is normal. i had a mechanic diagnose the problem by ear and that is where i found out it was the water pump. i would think it is the bearing and not the seal when its making the noise
is the water pump related to the amount of power the engine has?

Your mechanic must not have very much experience with Audi engines. On the Audi 2.8 and 2.7 biturbo V6s as well as the 3.0 V6 the water pump is driven by the camshaft belt. If the water pump fails the camshaft belt will probably break or skip causing very serious damage to the engine valves and pistons and could destroy the complete engine. As mentioned above you should immediately change the water pump and all the related camshaft belt components.

is there a 2.7L engine that audi makes that isn't bi turbo, i didnt think my engine had two turbos in it, not even one for that matter.
-Also to the other posters, why then would two different mechanics at two different shops recognize the rattling sound as the water pump.

2.8 is naturally aspirated
2.7 is turbo
The rattle probably *is* the water pump. If it's noisy, failure (and, at a minimum, damaged valves with it) is right around the corner. This noise can impact performance in a number of ways. The knock sensors can mistake the noise for knock and dial back ignition timing. Wobble in the waterpump changes the bank one exhaust cam timing.

I am going to take the car to a shop today. should i have them make an invoice saying the water pump is going bad, then bring that to the guy i bought it from and make his shop repair it.

If I was my car, I'd either do a full timing belt service myself or have someone else do it. If you bring it back, he will probably do the bare minimum. Bite the bullet and do a full timing belt service.
And stop driving the car.

LOL, Id think a "budding mechanic" would know to not drive the car with a comprimised water pump. Let the pros tackle this one boss. do all all the seals too.
