NO LONGER ACTIVE
P0012 = "P2006 - [2] B2/5b1 (Intake air temperature sensor) : Short circuit to positive or open circuit". B2/5b1 is the MAF sensor.

P0500 = "Event P20CA - [8] No CAN message 'Vehicle speed signal left rear wheel' from control module N47-5 (ESP control unit) or message faulty. : Read out fault memory of control unit ESP." This sounds like a faulty speed sensor for the left rear wheel.

Thanks Rudeney, I changed the MAF last year but honestly I got a cheap one from ebay, I will find the MB brand and switch it, so The VSP is the same like wheel speed ?

Yes, the vehicle speed is calculated by averaging the four wheel speed sensors, so VSP = wheel speed sensor.
