Reset an exhaust warning light by disconnecting the battery... hopefully it doesn't come back!
Sounds like itll be the post cat sensor, most common. Are you running std or running tuned??? the rear sensor is a Byte change to delete the sensor. This is done normally at stage 2 level where a high flow cat or larger dump pipe is used in conjunction with a tune. The rear sensor is normally only doing its job and thinks the cat is inefficient. Its not really. Running std then chekc the integrity of your exhaust at the joints, if any oxygen is sucked into the exhaust this can trigger the sensor or lastly the sensor itself has gone out to lunch

Running the GIAC tune.
light hasn't come back since the reset yet, although I've still got it scheduled for next thursday just in case.
I actually just had the O2 sensor replaced a couple weeks ago so I thought perhaps they'd stuffed something.
If it comes back over the weekend I'll get em to check out your suggestions, thanks!
Just because it happened to you, doesn't make it interesting
Look forward to doing a log on that when i service if you dont mind mate just to compare apples. Ive logged a few different tunes on the rollers and im always interested to see the differences.
Good to see you are finally going to wake it up mate!!!
Cheers

Hi mate no problems... Just need to go back to work after the floods to take delivery of the gear from DNA, we have been closed for the last 3 days since we are at Milton (business was not affected by floods - just could not get to work!!!) :-S

Exhaust light came back on... so car's going in for service tomorrow morning.
Hopefully the exhaust is cracked and I need a new one, then its just a few quick quotes to show work that aftermarket is cheaper than stock and we're done

I recently bought one of the stubby antennas. Definitly a major improvement over the old long one. Mine was pretty damaged aswell but I just love looking at my car parked next to a mkv gt and noticing the difference =P also bought a seat intake. Thanks tim!
Being a TDi, it's not as impressive as it might seem.
It's actually quite interesting to try and maximise economy, though, as you have to concentrate on traffic flow and upcoming light changes to minimise stops and acceleration periods while not acting as a roadblock. Jeremy Clarkson commented once that driving for maximum economy was far more difficult than trying to drive fast (in a sane manner) on public roads and I would agree (racetrack / closed road is another thing altogether).
It certainly is more entertaining than being frustrated by cars slowing you down when you are trying to drive at the speed limit the whole time. And I kept catching the same cars that were zipping in and out of lanes whenever I approached traffic lights.
