Mapping VW DTCs from a scantool to the raw data obtained

Motor Vehicle Maintenance & Repair Asked on February 26, 2021

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.

77E07590299903E1208 it`s 77E - adress ecu | 07 - number of bytes | 59 - positive answer from ecu | 02 -reportDTCbyStatusMask 99 upper bytes from ISO 14229

90 3E 12 - need to divide byte 90 how to "9" and "0", after "9" will change to "B1" and result: B103E 12 ,

also you can find how 903E12xh -- 9453074 number of DTC in list VAG.

08 - Status Mask describe in to ISO 14229
