Will it fit my Audi Q3?
Diesel mainly. Match the engine code — EGR units and coolers differ across TDI generations.
Tip: filter by your reg on eBay's compatibility check, or match the part number stamped on your old unit.
Signs your Audi Q3 egr valve needs replacing
- Limp mode / power loss

Fitting it yourself
Accessible on most engines; carbon build-up is common, so clean the mating faces.
