What changes the price

On the Audi A3, access takes on average 10% more time than the average for its class (premium), where the range is £335 – £915.

Price is per injector. A new injector must be coded to the ECU (IMA/C2I). A specialist rebuild often costs half the price of a new one.

Frequently asked questions

How much does a diesel injector audi a3 cost?

At an independent garage, expect £340 to £940, parts and labour included. Main dealer: £425 – £1,365.

What is book time?

It is the reference time set for a given job. Garages bill that time even if they work faster. If a quote shows far more hours than book time, ask why. Audi A3: 1 – 3 h.

Why is the dealer more expensive?

Dealer hourly rates run 40 to 60% higher on average, and genuine parts cost more than their original-equipment equivalents. Under EU rules, servicing outside the dealer network does not void the manufacturer warranty.
