Hello, New to the forum and Audi, just got myself a lovely A4 S-Line 2.0 T FSI Automatic, really nice car but I'm only getting 10-15MPG according to the average MPG on the DIS. Only done 100Miles and used half a tank, I'm pretty sure it should be a little higher than this, small amount of town driving but mainly Dual Carriageway. I'm not driving like a racing driver, gentle acceleration is used, car isn't doing anymore than 2000RPM, so very gentle driving. I'm not the best with cars so have no idea really what could be causing it, any ideas on things I should check before I take it to a garage and try and get them to diagnose the problem. I had someone scan the car and the only faults I could find are the following: Code: 3 Faults Found:012423 - Voltage Supply Relay for Engine Components P3087 - 004 - Electrical Malfunction - Intermittent Freeze Frame: Fault Status: 00100100 Fault Priority: 0 Fault Frequency: 1 Reset counter: 255 Mileage: 105560 km Time Indication: 0 Freeze Frame: RPM: 1403 /min Load: 26.3 % Speed: 0.0 km/h Temperature: 6.0âC Temperature: 6.0âC Absolute Pres.: 980.0 mbar Voltage: 10.414 V 008801 - Boost Pressure Control Valve (N249) P2261 - 008 - Mechanical Malfunction - Intermittent Freeze Frame: Fault Status: 00101000 Fault Priority: 0 Fault Frequency: 3 Reset counter: 255 Mileage: 105625 km Time Indication: 0 Freeze Frame: RPM: 1479 /min Load: 12.5 % Speed: 51.0 km/h Temperature: 84.0âC Temperature: 12.0âC Absolute Pres.: 1000.0 mbar Voltage: 13.970 V 005634 - Power Supply Terminal 30 P1602 - 002 - Voltage too Low - Intermittent Freeze Frame: Fault Status: 00100010 Fault Priority: 0 Fault Frequency: 2 Reset counter: 255 Mileage: 0 km Time Indication: 0 Freeze Frame: RPM: 0 /min Load: 0.0 % Speed: 0.0 km/h Temperature: -40.0âC Temperature: -40.0âC Absolute Pres.: 0.0 mbar Voltage: 0.000 V Readiness: 0000 0000 Any ideas?
