Frequently asked questions

How much does a diesel injector audi a4 cost?

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 A4: 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.
