Got the below VCDS error (bottom of post) relating to the DPF (diesel particulate filter) sensor G505 on a 60 plate Audi A1, 1.6tdi (CAYC) 105hp, so have ordered a replacement sensor.

However I'm struggling to find it! Below shows the ElsaWin workshop manual page, which shows it next to coolant reservoir. Photos below show:
  • Whole engine bay
  • Photo of coolant tank side - no sensor!
  • Back section behind the block (a google suggested this is the sensor, but it looks completely different to both the ElsaWin page and the sensor I ordered using ETKA info.)
  • Right side section, by the air box. only other sensor that seems to have small hoses going to it.
  • Photo of the sensor I ordered.
  • Screenshot of ETKA info.
  • Screenshot of ElsaWin page.
Any tips greatly appreciated! I'm sure i'm missing something completely daft here...
