if its not too late, i got an engineer to look at my car because i've been failed by dickson, but they didnt pick up the turbo timer, an engineer said it has to be connected to the handbrake so if the handbrake is off, the engine turns off straight away, but if the handbrake is up, then the engine can keep running, mine was already connected to it though.
i only got told by dickson to have the car legal height and to paint a line across both winding parts of my coilovers then extend the paint onto the thread so it all lines up and shows if its been moved or not.
dickson didnt say anything about my hks air filter last time but this time they might (booked in on thursday)
hope some of that helps
