Will it fit my Audi A5?

Diesel common-rail injectors are usually coded to the specific vehicle/ECU and often need programming after fitting — not always a straight swap.

Tip: filter by your reg on eBay's compatibility check, or match the part number stamped on your old unit.

Fitting it yourself

Accessible on most engines but diesel injectors can seize in the head; petrol injectors are usually simpler. Diesel jobs often need specialist coding after fitting.
