I scanned a VW Golf TDI 2015 using a scantool (at a workshop) and it gave the following 2 codes -
Engine module: P0103 - Mass Air Flow (MAF) (G70): Signal too High
Instrument cluster module: B103E - Fuel Level Sensor 1: Short to Plus
Then I hooked my laptop (PuTTY and elm327) to read the raw data and got the following data -

For Instrument cluster: Sent: 19 02 04 Reply: 77E07590299903E1208
Can someone please help me find out how can I arrive to the fault codes from the corresponding raw data. I can find out the faults myself instead of going to the workshop.
