SID, ignition cassette and touchscreen

Dear friends and fellow sufferers, at about 80 tkm and 4 years of age, the usual problems arise with my 9-5, MJ 2003. Despite the efforts of the search function (honestly) I have not received satisfactory answers to the questions that have been raised. I therefore ask you for help: 1. The SID shows the known pixel errors as soon as the display is warmed up by the operation. Because I certainly can not get the extension and the guarantee for a defrost How cheap is a new SID 1 (€ 176 net?) and what does the client practice at Saab look like? I have picked up somewhere that there are chances of culling with this misconstruction up to 100 tkm. 2. The Navi touch screen (Kenwood) can no longer be properly operated at low/high temperatures. It is as if the screen had slipped under the surface, so that unfortunately also the calibration keys can not be used properly. Does anyone know how kulant Saab behaves here? 3. Although I do not yet have any signs of smoking the DI cassette. But if this happens, more often unburned fuel enters the exhaust system, so that the departure of the Lamda probe in the cat. is the next step. Because I have no nerves to fight this out with Saab in the case of a case, I think to have the ignition cassette replaced precautionally. What is the current price of the new ignition cassette? and the culling behavior of Saab? Thank you for your efforts.
