When the car came back from service I refitted the box but it would not work giving a sensor short circuit error. TDi were very helpful and supplied two new wiring looms but it still would not work and gave the same error straight away. They also sent me a brand new uprated tuning box which I have not tried and is now for sale on eBay. Although it should not be possible it would appear that Porsche knew a box and had been fitted and somehow blocked it from working again. However, I can't prove this.

There's another possibility and that is an update for emission control purposes makes a software change that stops any tuning box working. In times of tight emission control and approval of vehicles in such matters, I have always thought it inconsistent with such provisions to allow non-standard vehicle tuning

Yes it could be that, no real way of finding out.
