Hi, The EGR valve itself is on a set of flexible pipework - usually stainless steel - which runs between the inlet manifold and the exhaust manifold. The EGR actuator valve is pneumatically / vacuum operated by a solenoid valve, controlled by the ECU ( aka the brane). It's not usual for the EGR valve itself to fail, more likely the solenoid valve or its electrical connector getting dirty. If you google for VAG TDI N75 valve you should get all the info you could possibly ever need :-)
Hope this helps, D.

I had the same problem, took it to the garage and they plugged it in to the diagnostic computer. I had just had alot of work done to it and there were about 8 different problem codes that came up on the computer. The mechanic cleared out all the problems, had me drive the car for a day or so until the light came back on. He hooked up my baby to the computer again and found only one problem. The O2 sensor was bad. The part cost about $200 from VW and $100 labor. Light has been off since. Being that the light could mean many things you definitely need to have it hooked up to a computer. If there are many alerts on the computer i would suggest doing what my mechanic did so that you're not spending money on someone fishing for the ultimate cause. Hope this helps!

Your EGR Valve is clogged and has to be changed. I have tried removing, cleaning and replacing it, this only lasts from one hour to one week.
The fault code 'P3103 V157 - Intake Manifold Flap' comes up on the diagnostics, and if you look in your fuse box (next to the battery) you will see a blown 10amp fuse. This is a sure sign that your EGR (or Intake Manifold Flap) is stuck.
This unit costs about £235 - £250.
Good luck mate

You need the OBD codes checked to be certain of the problem. If engine
is running ok with the light on, it may well be an oxygen sensor

Emissions Workshop means that the fuel / air ratio is incorrect. There
are many reasons for this problem. The ONLY way to be certain is to
have the OBD codes scanned. This will show the problem straight away.
If the car appears to be running ok, you may have a problem with an
oxygen sensor....but do the scan first. It is the quicker and cheaper
Good luck with it
