Audi Specialists
Audi Repair & Service in Rockville, MD
quattro, TFSI and S-tronic expertise for A3 through Q8 — diagnosed with VAG-specific tools and priced like an independent.
Audis share a parts family with Volkswagen, and a shop that works on them daily knows the platform's quirks: direct-injection carbon buildup, dual-clutch gearbox service and timing-chain tensioners that need attention at specific mileages.
We use VAG-specific diagnostic software to read every control module and follow Audi's maintenance schedule so small issues don't turn into engine-out repairs.
Models we service: A3, A4, A5, A6, A7, A8, Q3, Q5, Q7, Q8, S and RS models, TT and e-tron.
Common Audi problems we solve
Carbon buildup on direct-injection intake valves
TFSI and FSI engines suffer rough idle and misfires from carbon-caked valves. Walnut-blasting or mechanical cleaning restores power and economy.
Timing-chain tensioner and guide wear on the 2.0T
Earlier 2.0T engines can stretch chains and tensioners. Replacing them proactively prevents catastrophic engine damage.
S-tronic and DSG gearbox service
Shuddering or hard shifts often respond to a fluid-and-filter service and a mechatronic adaptation reset.
Oil consumption and PCV valve failures
Excess oil use is frequently a failed PCV diaphragm — a modest repair that saves a lot of oil and piston-ring wear.
Water-pump and thermostat housing leaks
Plastic housings crack with age. We replace the pump and thermostat together to avoid a repeat visit.
quattro center-differential and haldex service
Neglected AWD fluid causes binding and vibration in tight turns. We service the differentials and transfer units on schedule.

Audi questions, answered
How often should I service my Audi?
Audi calls for oil service about every 10,000 miles or yearly, with larger inspections at specific mileage milestones. We follow the schedule for your exact engine.
Is carbon buildup covered by warranty?
Typically not — it's considered a wear item on direct-injection engines. We can clean it affordably.
Do you service the Q5 and Q7?
Absolutely, including air suspension and quattro systems.
Can you work on Volkswagen and Porsche too?
Yes, we service VW, Porsche and Mini with the same tooling.
