I meant the ECU. The pressure sensor is supposed to be identical too I think, but the ECU I got had a different pressure sensor (maybe the previous owner changed it?). But I previously also purchased the proper pressure sensor.
I think your problem is different. I came across what you're describing on the M5board forum. Yours might be related to the instrument cluster actually.
Is the EML light on?
Is the red LED beside the Ladedruck dial lit up?
