Will it fit my Audi A1?
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.
Signs your Audi A1 fuel injector needs replacing
- Misfire on one cylinder
- Rough idle, hard starting
- Poor economy, smoke on diesel
- Injector fault code
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.
