Hi all,

Thanks again for the replies. Quick update:
The droning noise was a wheel bearing, replaced and noise issue is solved. Cost approx £300 at the local indi for reference.

Did not fix the sports diff light though, coincidental. That turned out to be 2 sensors (temp and oil level) and 2 of the clutch / fluid valves controlling the hydraulics in the sports diff. That was sorted out at the dealer - shade over £800 (ouch).

Master tech confirmed that the main cause of the light coming on is electronics / generally sensor problems. From the research I did this seems to be fairly common across sports diff on A4s.

im hoping its just a sensor as opposed to anything more sinister

does anyone have access to a parts catalogue and could find me the part number for the oil and temp sensor on the rear differential please

Thank you

It's a 2010 4.2 Tdi. Cdsb I think is engine code and mxx is gearbox I believe

Not sure if it's 2 separate sensors or one combined
It's the oil pressure and temperature sensor/s
On the sports diff

Thanks
Nath
