Yes, I did this when I was prepping the motor to get installed in the
Vanagon - it was quite plugged up!

Have you taken the intake manifold off and cleaned it? It's most likely
plugged!

Day two of figuring out the lack of power problem with my 1998 AHU TDI in
my
Syncro TriStar.
First, I thought it may be the pedal switches. An email from Germany and
looking at a working Jetta revealed that the answer is F=0, F36=0, F47=0
is
the state of not pressing any of the brake and clutch pedals.
The vehicle works great until I give it some boost for a while, like say
going up to about 90km/h - voila - the power is all gone and the MIL light
comes on. VAG-COM reveals:
00575 Intake Manifold Pressure Control Difference 17-00
Before I got the intake manifold hose problem fix (they would pop off
under
boost) this always came up when they slipped off. Now the whole entire
intake system is air tight and I have a boost gauge connected - goes right
up to 14 to 15 PSI. The MIL will come on during a prolonged period (20
seconds) of full boost, like when you are going from 60 to 90 km/h in 4th
gear.
Does ANYONE have any suggestions on what the problem is? Is there a limit
to how far away the ECU can be from the intake manifold. I have about
150cm
of 1/8" hose connecting it (connection is at driver side front of the
engine
bay - ECU is in the tail light area).
When the engine goes into to "limp home mode" you can hear a rapid
clicking
in the engine compartment. When you clear the codes, with the engine
still
running you can never clear the 00575 and the clicking doesn't stop until
you turn the engine off, then no problem and you will never get 00575
until
you go for a drive again.
