Had my new (to me) Q5 for a couple of months now and thought I'd sign up having found forums very useful with my previous cars.

2015 Q5 Mk1 facelift with a 3.0TDi S-Line Plus.....

Still learning lots as this is my first Audi after spending the last 9 years with a Mk4 Ford Mondeo 2.5t, but I have managed to make a few modifications to her already including -

OBDEleven module so I've activated Drive Select with additional modes, fog/cornering lights and gauge sweep.

Interior LED light swap.
Carplay unit from AliExpress so I can have Android Auto again.
Front and Reversing camera's which link into the above unit.
Rear armrest from a Q7 so I could get the integrated cup holders, was surprised it was a direct swap.
Retrofitted footwell lights front and rear.
Retrofitted the active door warning lights and puddle lights.
Nice set of alloy pedal covers that match the Mrs' Skoda Enyaq's.
RamAir airfilter.
Botslab G980H front and rear dashcam from Amazon.
And an adjustable dipstick as I'm stuck in my ways 😁
