Finally a Saab! 9-5 Aero MY2004 – And already something broken?

Good evening forum! Would like to thank me for the great tips and experiences that this forum has given me in recent weeks and have now finally led to my purchase today: Saab 9-5 Turbo Aero 2.3 sports combi MY2004 ( the link won’t go long anymore: http://www.autoscout24.de/Details.aspx?id=l3hzjl1ychaj ) KM 122,000 km First registration:11/2003 Power: 184 kW (250 hp) HU test: 08/2012 Outer colour: Silver Metallic 8 times matured on aluminium Has me gl I was not really convinced on the way back in today’s weather conditions and I was brought home safely – bombastic road position – giving gas was of course not really inside. First drop of wormwood: Unfortunately earlier the “engine” lamp started to light up, I am pretty sure that this was not the case with the test drive yet – engine runs however quite normal, hope not anything bad. Will the seller anyway step on the fingers, because the cruiser praised in the advertisement at all not at all available! I didn’t notice in my happiness when driving However, the joy over the car prevails – everything is top, super cared for etc. Thanks again! And maybe someone can take the fear of the engine damage away from me immediately?
