Hi there.

I have an 05 plate Touran (2.0 Tdi Sport). I have noticed,
particularly on long journeys, there appears to be less and less air
over time coming out of the vents.

It gets to a point where I have switched it out of "Auto" mode and set
the fan to FULL speed and both temps to 16 Degrees withour any
significant air flow dispite hearing the fan behind the dash trying to
blow the air without any noticable results ? (I don't feel it blowing
anywhere else.

When the car is then left with ignition off for a few mins it appears
to work again with LOTS of air coming out of the vents. Then over a
short time it then reverts back to its rather astmatic efforts.

Ocasionally turning teh AC compressor off and on again sometimes
resets it, as does setting teh temp to LO, but both of these are not a
guarantee to get it funtioning as it should.

It appears as if the main flow is being restricted by something over
time ? Dealer has looked at it and NO fault codes recorded !!

It has 1 month left on VAG warranty, so it's booked in for a longer
look !

Any thoughts as to what this problem could be ?

Thanks in advance.
Andy
