Find the cause before paying for the guess.
Structured mobile testing follows the evidence behind warning lights, electrical concerns, drivability issues, no-start conditions, and related symptoms before a repair is recommended.
Pricing
Mobile Diagnostic Service — $250
The service covers one primary documented concern, reasonably related symptoms, up to two hours of testing, travel inside the regular service area, diagnostic findings, and a repair recommendation or next-step explanation.
A $50 non-refundable down payment is required. The remaining $200 is due when Grease Nomads identifies a supported cause and provides a repair recommendation, even if the repair is declined. If no supported cause is identified within the included scope, no remaining diagnostic balance is due. Price shown before applicable taxes; repairs, parts, supplies, and approved travel fees are separate. Additional testing beyond two hours requires explanation and approval through a new estimate.

What's covered
Diagnostics services we perform on-site
Warning Lights and Check-Engine Lights
Document the concern, review relevant data and codes, and test the system that set the warning rather than treating code retrieval as a diagnosis.
Electrical Concerns
Structured testing for accessible circuits, wiring, connections, switches, sensors, and electrical symptoms connected to the documented concern.
Starting and Charging Concerns
Battery, starter, alternator, cable, connection, voltage-drop, and related testing as the symptom requires.
No-Start and Intermittent-Start Conditions
Evidence-led checks for power, cranking, fuel, ignition, signals, and other accessible causes within the included scope.
Drivability Concerns
Testing for rough running, misfires, stalling, hesitation, poor acceleration, and related symptoms tied to the primary concern.
Noises, Vibrations, or Performance Changes
Inspection and testing to narrow the source of an unusual sound, vibration, or change in vehicle behavior when it can be reproduced safely.

What does the $250 diagnostic service include?
It includes one primary documented concern, reasonably related symptoms, up to two hours of testing, travel within the regular service area, findings, and a repair recommendation or next-step explanation. Additional unrelated concerns require a separate scope.
How does diagnostic payment work?
A $50 non-refundable down payment is required. The remaining $200 becomes due when Grease Nomads identifies a supported cause and provides a repair recommendation, even if the repair is declined. If no supported cause is identified within the included scope, no remaining diagnostic balance is due. Diagnostic charges are separate from repair charges and are not credited toward repairs.
What is the difference between a code scan and diagnosis?
A trouble code tells us where the vehicle detected a problem; testing determines why the problem is there. The process is to document the concern, inspect and test, follow the evidence, explain the findings, and recommend the next step. Testing beyond two hours is explained and requires approval through a new estimate.
What repair-result protection applies?
If Grease Nomads identifies a supported cause, performs the recommended repair, and the same documented concern remains, report it within 30 days before anyone else disturbs the relevant system. You may choose follow-up diagnosis at no additional diagnostic charge or a refund of the $200 diagnostic balance. The $50 down payment, repair labor, parts, supplies, travel, taxes, and other repair costs remain non-refundable solely because the first repair did not resolve the concern. This is not a full vehicle warranty.
