Hey mate, this link below should help if its not already the one you have been looking at. It includes before 2010 locations and after 2010 locations for air suspension fuses and relays.
what fault codes do you have now in regards to your new compressor install?
2005-2015 Audi Q7 Fuse Box Diagram » Fuse Diagram

Thank-you for your help .Thats seems to be the confusion as diagram says centre dash panel as location .I have attempted to up load some photo’s and noticed that one on the 40 amp fuse maybe be blown (from zooming in on photo).

I uploaded photo’s that i thought would come up on this area but they are in ‘galley’ .One is paper with codes that initially came up and the other is relay carrier .

Codes that came up initially now only have 0136 & 01826 after tried to clear.


Relay carrier located in drivers side (07’ Q7 TDi RHD) foot well behind panelling , upper right (basically beside /behind fuses on right side) I now see bottom 40amp maybe blown ?

Hey mate, firstly the 2 fault codes you have 01826 = steering angle sensor G85, been RHD when you changed to compressor you my have accidentally bump off the wiring to the steering rack box that pretty much sits next to the compressor behind the r/h wheel arch when removed. Kinda like below the floor where you accelerator pedal is. There is a sensor there that determines where the wheels/ steering wheel is pointed,
Secondly P0136 = O2 sensor error on your exhaust system, once again being a v6 possibly it may be unplugged on the r/h side near the steering box mate.

As for your fuse / relay locations mate the below pics should help. If that 40amp fuse is popped it is for your ABS control module located as 2b mate.

I managed to locate fault - blown 40amp fuse under passenger seat , $6.71 NZD .I double checked wiring connections to compressor , then checked all relays were seated and then went around all fuses until i came to the one under the seat and ‘bingo’ ‘hallelujah’ .I always had in my head that it was something simple (no power to replacement new compressor)but after gathering too much info after work from internet and had people saying get codes first , computer gone into safety mode , relay in wrong place etc etc .All warning lights gone now and compressor working fine . Thank-you very much for your help much appreciated mate!
