DEALERSHIP-GRADE BMW DIAGNOSTICS,
AT YOUR DRIVEWAY

✅Mobile, Across Orange County ✅Veteran-Owned ✅English and Tiếng Việt
WHAT WE DO
Three services, all mobile. Most jobs start with a scan, so you know what's wrong before
you spend money on parts.
Mobile Diagnositcs with ISTA
ISTA is the diagnostic and service software BMW dealerships use. It reads every control module in the c ar, gives factory fault descriptions, and walks through the manufacturer's test plans instead of guessing from a generic code.
✅Full vehicle test across all modules
✅Check engine, DSC, airbag, and other warning lights
✅Fault memory read, explained, and cleared once fixed
✅Guided test plans to confirm the failed part before replacing it
✅Pre-purchased scans for used BMWs
Diagnosis tells you what is wrong. Repair is quoted separately, and nothing is done without your approval.
Mobile Repair, BMW and Other Makes
Many repairs don't need a lift. We handle them where the car is parked, and we work on more than just BMWs only.
✅Sensors, coils, and ignition parts
✅Batteries, including registration on BMWs
✅Brakes, fluids and routine maintenance
✅Electrical faults and component replacement
Key Fob Programming
Spare keys, replacement fobs, and fobs that stopped working, programmed on site so you don't need a tow to a dealer.
✅Replacement and spare key fobs
✅Reprogramming after a battery or module change
✅Proof of ownership and ID required

COMMON QUESTIONS
Short answers before you call.
What is ISTA, and why does it matter?
ISTA is the software BMW's own dealerships use to diagnose and service their vehicles. A generic code reader shows a few engine codes. ISTA reads every module and points to the factory test for each fault, which means fewer parts repalced on a guess.
Can you fix it on the spot?
Often, yes. Sensors, coils, batteries, and many electrical repairs can be done where the car is parked. Jobs that need a lift or specialty equipment are flagged after the scan, so you decide what to do next.
What do i need for key fob programming?
The car, any keys you still have, and proof of ownership with photo ID. Supported models and years vary, so confirm your car when you book.
Do you work on cars that are not BMW?
Yes, for mobile repair. ISTA-level diagnostics is specific to BMW.
Will I get a price before work starts?
Yes. After the scan you get the findings and a quote. Nothing is repaired until you say go.
WARNING LIGHT ON?
GET IT SCANNED.
Tell us the model, year and what the car is doing, and we will confirm whether we can
