Thanks Greg. What type of cleaner would you recommend for the EGR Valve? Also do you know where exactly it's located?

Liquimoly 2730 is the code I use, and you just spray it in after the MAF sensor, ideally just before the turbo down the PCV oil blow by connection, this is the big 25mm hose sticking straight up over the back of the engine on the passenger side just before the turbo charger. Follow the instructions on the can, can't hurt.

I thought we should spray it just before the ASV/EGR assembly?

Ok so have been driving the car since my last post and there has been none of the symptoms above. I ended up taking it to Dandyvolks, the mechanic there checked the codes and none of the previous ones were present only the throttle flap sensor (don't quote me on that). He checked to make sure it wasn't sticking, which it wasn't and then carried out some more tests via the computer.

At the end of all the testing everything passed and was ok so he advised me to basically give it a good blast out as he said it's more than likely carbon build up. This I suspect is true as my daily commutes are a mere 12km to work and the same back, this is all city traffic driving too. When I left the garage to drive home which is a 40min drive to Box Hill I made sure keeping the revs above 3-4000 for almost 15min then towards the remainder of my journey through a residential part I held the gear in 2nd and took the revs all the way up to the red line and held it there for a couple of minutes. I must say since doing all that the car has been performing really well maybe even better than before.

I believe thats referred to as an Italian tune up.

Get it scanned, light can mean hundreds of things. It's probably going to say throttle flap again, in which case you need another one, they do die on mass in TDI's. Look to the UK for cost effective used ones or probably Darkside Developments for well priced new ones.
