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.

  • Why not just use a program lik OBD Auto Doctor. This is just an example ... there are others. There is free software out there ... why reinvent the wheel? – Pᴀᴜʟsᴛᴇʀ2 Mar 8 at 13:44
  • I have tried OBD doctor but it didn't give any DTCs. Maybe it reads mode 03, 07 (basic OBD commands) only – Soumya Sen Mar 9 at 12:04
  • There are other options out there. – Pᴀᴜʟsᴛᴇʀ2 Mar 9 at 16:01
  • yeah I tried the free ones, neither one reads other than engine. – Soumya Sen Mar 11 at 6:34
