Hi Eddie
On a Turbo, any cheapie handheld OBD2 code reader/scanner will read engine fault codes and reset a cheeck engine light. It won't read any of the other control modules on the car though. For that, you would need a Durametric scanner, or a Porsche tester. The Durametric is by far and away the best DIY tool designed specifically for Porsches. The latest version 6 of the tester will even do some basic coding, and has the facility for brake bleeding on the 9x6 cars.
Bleeding a Turbo cooling system can only be done with a Porsche tester at the moment, but Durametric are continuously adding facilities to the new system, so I expect that they will be introducing it fairly soon. Their suppost is very good, so if you are interested in one, try contacting them to see if/when they have it planned. You can buy the system from them direct at www.durametric.com or from the UK distributor at http://www.hickleys.com . By the time you have added import duty and VAT there isn't much difference than buying direct.
I have no affilliation with Durametric. I have one of the older Professional models which works very well, and I keep in the car.
