THE REQUIRED PATH
Every procedure starts with evidence.
Coding or tuning questions are never treated as a shortcut around diagnosis. We require an appropriate documented diagnostic baseline before reviewing vehicle condition, platform support, and possible next steps.

- 02Repair, adaptation, or relearn pathOnly what the evidence supports
- 03Procedure compatibility reviewVIN, condition, software, and support confirmed
Your request is free. For a confirmed mobile appointment, we use the exact service address to quote round-trip travel. If a travel reservation is required, it is itemized and paid separately before dispatch; the diagnostic fee remains separate.

WHAT WE CAN DO
Evidence beyond the fault code.
We combine full-system scanning, live data, supported active tests and service functions with direct electrical checks. German vehicles are our specialty, and selected basic concerns on other makes are reviewed before booking.

THE PROCESS
Your vehicle gets a test plan—not a parts cannon.
Three disciplined steps turn a confusing symptom into a decision you can act on.
01
Connect
We document the symptom, verify the exact vehicle platform, stabilize battery voltage, and connect the right diagnostic equipment.
02
Diagnose
We scan every relevant control unit, review live data, and test power, ground, wiring, and vehicle networks.
03
Decide
You receive clear findings, a repair direction, and an honest answer about coding or programming support.
THE REPORT
Electronic findings you can actually use.
Modern vehicle electronics can produce dozens of stored faults from one weak supply or failed communication line. We organize the evidence so you can see the primary problem, related faults, and next test.

THE PLATFORM ROADMAP
Focused expertise. Responsible scope. Clear answers.
German vehicles remain our specialty, beginning with supported platforms that commonly need electronic and electrical problem-solving. Selected straightforward concerns on other makes are reviewed separately by year, model, VIN, and symptom.

THE SHOP CARS
The same discipline goes into our cars and yours.
Our M240i and 540i are working shop cars—built, tuned, and maintained with the same diagnostic discipline we bring to every appointment.
They are more than transportation. They keep us hands-on with the BMW systems, electrical behavior, data, and drivability concerns our customers ask us to investigate across Greater Memphis.

WHO WE ARE
Owner-led diagnostics. Honest answers.
Titan Diagnostics is an active-duty-owned mobile diagnostic service operated by Titan Services Groups LLC. We specialize in German-vehicle electrical and electronic systems and accept selected basic concerns on other makes after a support check.
Our work begins with a documented vehicle baseline: full-system fault mapping, live data, supported active tests, and targeted power, ground, charging, and network checks. Customers receive clear findings and a practical next-step plan—not a list of parts based on a fault code alone.
We review each VIN and request before booking so we arrive prepared and accept only work we can support responsibly. Unsupported dealer-only flashing, security functions, and retrofits are referred out.

STRAIGHT ANSWERS
Before you book.
Do you work on every German vehicle?
Coverage is platform-specific. We currently prioritize supported BMW, Mercedes-Benz, Audi, Volkswagen, MINI, and Porsche systems. Every request is confirmed from the VIN before scheduling.
Do you work on non-German vehicles?
Yes, selectively. We currently accept supported basic warning-light, no-start, battery, charging, scan-based, sensor, and circuit concerns on other makes after a year, model, VIN, and symptom check. Advanced coding, programming, and tuning are never assumed or guaranteed.
How does mobile service work?
We confirm the vehicle, exact service address, symptom, and platform support first. The address lets us verify mobile coverage and quote round-trip travel before scheduling. Before any supported procedure beyond diagnosis, we also confirm that the environment and battery support are appropriate.
What does the mobile travel reservation pay for?
Some confirmed mobile appointments require a separate, itemized travel reservation before dispatch. It covers only the approved round-trip travel to and from the service address; it does not pay the diagnostic fee or authorize a repair. The diagnostic balance is due separately under the agreed scope. Any later return trip is itemized and approved separately, and no payment is taken with the initial request.
How is service scope determined?
We accept only work supported by the vehicle platform, current equipment, training, documented risk controls, and operating conditions. If a job requires unsupported dealer security access, flashing, or repair capability, we explain the limitation and refer it appropriately.
What can Titan Diagnostics diagnose and service?
On supported vehicles we can scan available control units, graph and record live data, run bi-directional active tests, register batteries, place the EPB in service mode, perform service resets, calibrations and adaptations, perform limited manufacturer-dependent coding when confirmed, and produce a diagnostic health report. Exact functions are confirmed by VIN before booking.
Can I book tuning by itself?
No. The current public remote offer is scan-report review and compatibility planning, not tuning execution. A documented baseline is required before we can explain whether a supported future or specialist path may exist.
Can you help customers outside Memphis?
Yes. Customers worldwide can purchase the fixed-scope review of an existing scan report. We use the VIN, country or region, supplied evidence, vehicle condition, and requested outcome to deliver written findings and compatibility guidance. It is not a live remote session. Physical faults and repairs require a qualified person at the vehicle.
Can you program any control module?
No. Limited manufacturer-dependent coding and adaptations may be available locally after a VIN and condition review, but we do not promise dealer-level ECU flashing, ISTA, FSC injection, or retrofit procedures. The $49 remote review does not perform coding or programming.
