Parts & factory-licensed tooling
01 / Marques
Four makes. Done properly.
We don't service everything that rolls in. We go deep on four German marques, which is why we can code a module, not just swap a part.
M & N-series · DME / DDE coding · ISTA programming
S / RS · DSG & S tronic · ODIS module flashing
AMG · 4MATIC · XENTRY SCN coding
911 / Cayman / Macan · PIWIS diagnostics
If it isn't one of these four, we'll refer you to someone who lives in it — same as we'd want.
02 / Capabilities
What we actually do under the lift.
Diagnosis first, parts second. Every job opens with a factory-tool scan and a written read on what the car is really telling us.
Factory diagnostics & coding
Fault-tree diagnosis on the same software the dealer runs — ISTA, ODIS, XENTRY, PIWIS — including module coding, retrofits, and DME / DDE adaptation.
ISTA · ODIS · XENTRY · PIWIS
Performance & forced induction
Turbo systems, charge pipes, intercoolers, and supporting mods done with OE-grade hardware and post-install datalogging — not parking-lot tuning.
N54 · S55 · B58 · EA888
Transmission & driveline
DSG / S tronic mechatronic service, ZF 8HP fluid and adaptation, clutch and differential work with factory fill specs and reset procedures.
DSG · S tronic · ZF 8HP · PDK
Chassis, brakes & alignment
Big-brake and OE brake service, coilover and air-suspension corner balancing, and string / Hunter alignment to factory or track sheet.
Coilover · Air · BBK · Alignment
Scheduled & out-of-warranty service
Inspection I / II equivalents, timing chain and water-pump intervals, carbon cleaning, and the deferred maintenance the dealer waved off.
Service · Timing · Carbon · Cooling
Pre-purchase inspection
A full PPI on a car you're about to buy — compression, leak-down, full fault scan, and an honest written verdict before the money moves.
Compression · Leak-down · Scan
03 / Equipment & parts
The tooling is the difference.
A general shop guesses with a generic code reader. We run the factory software for each marque, fit OEM or OE-supplier parts, and keep the receipts. The bay is the credential.

Names, not a service desk.

05 / Diagnostic request
Tell us what the car is doing.
We don't take impulse bookings. Send us the car and the symptom and a technician — not a call-center — reviews it and replies with a diagnostic plan and a window. The more detail, the sharper the first read.
- Reviewed by a marque technician, not a service writer
- A written diagnostic plan before you commit
- Typical reply within one business day

06 / Owners
From people who drive the cars.
4.9 / 5 across 200+ verified owner reviews
2016 BMW M3 (F80) · S55 charge-pipe
“The dealer wanted to throw a $4k turbo at a boost leak. Marcus smoke-tested it, found a split charge pipe, and coded out the soft limp. Done in a morning.”
Ryan T.
2019 Audi S4 (B9) · S tronic service
“They datalogged my S4 before and after the DSG service and walked me through every line. This is the only shop I trust with the B9.”
Priya N.
Porsche 911 (991.2) · pre-purchase
“Did a PPI on a 991.2 I was about to buy. The leak-down numbers killed the deal and saved me from a $20k mistake. Worth every cent.”
Daniel okabe
2018 Mercedes-AMG E63 (W213) · SCN coding
“XENTRY coding on my E63 that two other shops couldn't touch. Sofia had it adapted and driving right the same day.”
Marisol V.
07 / Questions
Before you send the car.
Still deciding? Call the shop — a technician picks up, not a service desk.
Are you really a dealer alternative, or just cheaper?
Both, in that order. We run the same factory software (ISTA, ODIS, XENTRY, PIWIS) and fit OEM parts, so the work is dealer-equivalent — we're simply not carrying a showroom and a service-lane sales target on top of your invoice.
Will service here affect my warranty?
If your car is still under factory warranty, independent service is protected in the US under the Magnuson-Moss Warranty Act as long as OEM-equivalent parts and procedures are used — which is exactly how we work. For powertrain-warranty cars we'll tell you honestly when the dealer is the right call.
Do you only take the four marques?
Effectively, yes. BMW, Audi, Mercedes, and Porsche are where our tooling, training, and parts pipeline live. We'd rather refer you to the right specialist than do an unfamiliar marque at half-depth.
Why a diagnostic request instead of online booking?
Because a good diagnosis can't be guessed from a drop-down. A technician reads your symptom, decides what the car actually needs, and books the right amount of bay time — so you're not paying for a slot that doesn't fit the job.
Do you do performance work, or just repairs?
Both, with the same discipline. Forced-induction and chassis work is done with OE-grade hardware and proven on datalogs — not eyeballed. We'll also tell you when a mod isn't worth it on your platform.
