Turbo Leak?

So, and I'm going to try and describe it to the best of my ability, my car has started to feel like something is wrong with the turbo. Under acceleration, the turbo will sometimes not kick in until about 4k(usually around 3k in the past) and then sometimes it will hit around 3k but then fade away and come back. It feels like someone is holding the car back and then letting it go.

Does this make sense to anyone and if so, what could this be? I'm sure I;m not the first with this issue, but trying the search with a few different words yielded no good results for me. I've come to the conclusion that I am search button illiterate.

First step would be to check for any stored engine faults, then pressure test it

Could be a faulty sensor, MAF and coolant temp sensor can cause similar problems to what you are seeing. Could also be as you suspect a leak somewhere in the system. How old is the car and how many miles?

Do you have a FMIC?

This is circumstantial, but could be heatsoak...

You could be kicking in and out of soft limp mode which can be caused by any number of things..

It's an 2001 with 97k. And how do I check for the formentioned things?

And no I don't have a FMIC.

Depends on if you want to do the work yourself or not.

If yes then get yourself a <a href="http://ross-tech.com/">vag-com</a> so you can check for faults, or find someone else in your area that has one and can help you out. It's a good investment tho if you plan to work on the car yourself.

Mr Schwing sells a <a href="http://www.modshack.info/Pressure.htm">pressure tester</a> for our cars that I have used in the past that works well for tracking down leaks.
