Finding the right Audi repair shop is a different decision than finding a mechanic — you’re choosing the place your car will be cared for over years of ownership: the equipment it will be diagnosed with, the parts that go into it, and how the business treats you when something unexpected comes up.
Auto Engineering has been that shop for German car owners since 1956. Our independent repair facility at 436 Marrett Road in Lexington, MA serves Audi drivers from Arlington, Bedford, Burlington, Belmont, Waltham, Concord, Newton, Winchester, and across Greater Boston.
A Shop Equipped for Audi — Not Adapted to It
Factory-Level Diagnostics
Audi’s electronics can’t be properly read with generic scan tools. Our shop invests in factory-level diagnostic equipment, so faults are identified the way the dealership would find them — without the dealership process.
OEM & OEM-Quality Parts
We build repairs around OEM and OEM-quality components and premium fluids, including Motul oils, so the work holds up the way Audi intended.
An Independent Shop, Accountable to You
No service-advisor wall, no quota-driven upsells. You talk directly with the technician working on your car, and nothing gets done without your understanding and sign-off.
The Dealer Alternative: Same Work, Better Bill
Audi dealership labor in the Boston area commonly runs $250+ per hour. As an independent shop we deliver the same caliber of work at rates that typically save our customers around 30% — see our dealership pricing comparison for the numbers by brand.
And because federal law protects your right to service your vehicle outside the dealer network, maintaining your Audi at an independent shop does not void your factory warranty when the work follows manufacturer specifications.
Audi Models We Service
Our shop handles the full Audi range, from daily drivers to S and RS performance models:
- A3, A4, A5, A6, A7, A8
- Q3, Q5, SQ5, Q7, Q8
- S3, S4, S5, S6, S7, S8
- RS 3, RS 5, RS 6, RS 7, TT RS
- Audi e-tron models
We’re also an authorized APR and Integrated Engineering tuning dealer for owners who want more from their Audi.
Repairs Our Shop Handles Every Week
Beyond factory scheduled maintenance and oil service, the Audi work that comes through our bays most often includes timing chain repair, DSG transmission service, check engine light diagnostics, brakes and suspension, and walnut-shell carbon cleaning for direct-injection engines.
Visiting the Shop
You’ll find us at 436 Marrett Road (Route 2A), Lexington, MA 02421 — about a mile off I-95/128 Exit 30A, an easy stop from anywhere along the Route 2 or 128 corridors. We’re open Monday through Friday, 8:00 AM to 5:00 PM, with affordable loaner cars so a repair doesn’t cost you your week. Book online through our service scheduler or call (781) 676-7700.
Frequently Asked Questions
Do you offer loaner cars while my Audi is in the shop?
Yes — we offer affordable loaner cars, and many services are completed the same day.
How is an independent Audi shop different from the dealership?
Same factory-level diagnostics and quality parts, but you deal directly with the technician, approve work personally, and typically pay around 30% less in labor.
Will using your shop affect my Audi’s warranty?
No. Federal law protects your right to have maintenance and repairs performed by an independent shop; we follow manufacturer specifications and document everything.
Do I need an appointment?
Booking ahead through our online scheduler guarantees your slot and a loaner if you need one — but call us for urgent issues and we’ll do our best to fit you in.
