Turbo is usually not easy to repair. Go to VW Mechanic.

Check the fuel pressure.

This is a result of either a bad solder job at the factory or just bad solder. You can remove your gage cluster and remove and resolder the joints at the back of the 2 indicators. there are several sites on the internet that have specific instructions.

as it should or as you thought it would ?

TSI is a technology that combines supercharging AND turbocharging

The supercharging will give power at low revs and the turbo at higher revs.

this means that there isn't somewhere where the power "kicks in".

Its power from idling to the red line. full stop.

If you think it isn't right take it to a VW dealer to have it checked out.

However, faulty turbos or superchargers make a car undriveable, so maybe you are not receivinbg as much as you had hoped.

A new turbo charger is about $340, but you can buy the bearings and seals and rebuilt if yourself for about $100

It is not hard, and it does not take long to do.

I normally do not bother with synthetic, but with a turbo charger, it might be worth it. What really seems to ruin turbo chargers the most is not letting them cool off before parking.
Once you turn off the engine, there is no longer any cooling, so the build up heat will burn up the oil and seals.
Run the engine for at least 5 minutes below turbo levels, before shutting down the engine.

On the VW Jetta MkV, the cabin filter is underneath the glove box. Access is gained by removing two plastic screws, gently pulling down a piece of foam insulation, and releasing a single clip to detach the filter. It (and some debris from it) fall easily onto the floor mat below. Insert the new cabin filter, replace the insulation, re-screw the screws, and within 3 minutes, you're back in business with fresh air and clean hands besides!

you might have a bad coil get it tested with computer to see witch one is bad same thing was going on with sister car rpm would go up felt weak it ended up being a bad coll.

Try a VW car and van Breaker. You may need to take the pipe of the breakers car, so take some tools with you. You could try a motor factors other than VW. Hope that helps you.
