Hej, hej Vitesse,
True... these units tend to fit/sit not fully flush with the ACC panel but it is only 1 to 2 mm difference and I am not bothered by it because I am looking at it from an above angle
Might I ask if your ELM also shows oil temperature? Because mine doesn't (it shows coolant temperature OK though). I am using Torque (free version) so I wondered if the Pro version might make a difference.
