I have no power when I put my foot down, the Turbo spins and whistles but there's no power. Ive heard about leaky pipes and MAF sensors but all these have been checked.

Is there a sensor that could cause such a problem? If so, where is it located and what is it called?

Any other theorys on my problem are more then welcome

Thanks Guys XD

There is a boost sensor on the intake piping right before the intake manifold. It could be bad.

First check for any error codes. If there is a sensor causing the problem it could have tripped an error code.

Read this and go through all the steps.

You do need a VCDS cable to do the advanced tests but there's no other way to fix it and buying the cable is a lot cheaper than throwing money at it trying to fix the problem.

Let us know where you are getting hung up. If you figure out what is the cause and post it, it can help others.
