LOSS OF POWER SOUNDS LIKE A BAD MASS AIR FLOW SENSOR, EASY FIX. GOOD LUCK.

I would bet money that your intake plenum is plugged up... this is KNOWN to happen to MK4 TDIs. The combonation of crappy USA fuel and ExhaustGasRecirculation cause this to happen.The only real fix is to remove the plenum and clean it. It is a very messy job...lots of black goop.
If you do some research about this on the internet, you will find several do-it-yourself cleanings complete with photos.

Possibly the mass air flow sensor, as earlier reply suggested. I had a problem at 80kmi which was sluggish acceleration (low torque), like the turbo quit. Changed the MAF sensor and it was back to perky self. I did not find a max speed as you did, just took forever to get there. Lower gear helped.
I'm wondering if you have a obstruction in the fuel supply (tank vent??) that limits the fuel flow and therefore the speed. Can you find a flat spot in lower gears at same rpm? If so that would suggest a fuel supply problem.

oooh ok now maybe we are getting somewhere. hmm. I will look into the intake and the sensor issues.
I didn't really find a "flat spot" ...but if I ever need to step on it, go up a hill, or go flat beyond about 70 it will just not do it. Thanks so much ..everyone for the input. I was really getting worried. in this day and age...getting 50 mpg is like gold. I really enjoy the savings.

Tomorrow I’m going to look at a 2005 Beetle GLS TDI 5spd manual with 21,400+ miles on it.
The dealer is asking $18,999, Blue Book is $19,150
Any thoughts on the price. Seems like there are used TDI’s showing up on the lots these days. I wonder why?

Probably trades on the Jetta Sportwagen TDI. That does seem a bit high. Though that is one of the real pluses with the VW TDI, high resale value. That is very low mileage for a 4 year old car. Make sure it has a clean title, no wrecks.

I own a 2006 Beetle with TDI. It is a great car except for one thing. I am only about a thousand miles from replacing tires. Car just rolled over 20000 miles. Mechanically otherwise, great. Watch the electronics, ie: door locks, trunk lock, and cruise control. Mine has been in the shop under warranty for all of these things. Usually a module replacement was all that was necessary.

The factory tires are pretty crappy when it comes to premature wearout. If you try to replace with exact same tires... you will find there is NO MILAGE WARANTEE at all on them.
Consider getting 4-wheel alignment before installing QUALITY tires with a milage-warantee. Rotate them at least once a year. They should last for well over 50,000 miles.

thanks for the reply. Can you recommend a good replacement model and brand. I have looked at Michelin and Continetal. Both are similiar. Pricing a good tire is not an issue. We have a place near us called Discount Tire. They can get me just about any brand of that I want to put on her.
Thanks for the info on what to do.

I suggest you consider buying five Michelin Primacy MXV4's. These tires seem to be the highest rated all-season touring tires. I'm putting a set on my 2006 Jetta TDI because the original Bridgestones wore out. All auto makers are now recommending not using tires that are more than 5-7 years old, so I rotate all five tires to avoid having an old spare that is unsafe.
