I was driving and guned it and the turbo made a noise and lost power. Its seems as if the turbo went im not sure.At 2 rpms when its suppose to spull it makes a noise. How much is it to replace turbo's with the drop of the engine?

 

What kind of noise does it make? If it is a grinding noise it could be your turbos.

 

If it still spools then you havent blown up a turbo, could maybebe an oil leak if theres a grinding noise. Take it to the dealer if it still under warranty.

 

Maybe you are in limp mode. Go & get the car scanned.

 

limp mode starts that low in the RPM range?

 

It can start @ idle if something is that wrong with the car.

 

how do you get it out of limp mode? and what exactly does limp mode do.

 

With my past experience on trucks limp mode throws a code in the ecu because the clutch slipped when accelerating with the turbos spooled, I'm guessing you have a tip. In limp mode it keeps the tranny in a certain gear until the code is cleared. Correct me if I'm wrong but this what I know limp mode as. If this is the same with audis, build up the tranny to avoid limping it or take some power out of the tune.

This is probably way off what Audi's limp mode is [&:]

 

It still drives but it make a hissing noise as if one turbo is losing power. and i have forge div valves and bipipe i have no idea whats wrong

 

It sounds like a turbo could be going out but it is hard to say without being there.
