Mobile mechanic, Mississauga, Oakville, Milton, Brampton and Etobicoke
I do diagnostics at your home or work anywhere in Mississauga, Oakville, Milton, Brampton and Etobicoke. I diagnose it where the car sits, quote one flat price before any work, and hand you the old parts when it is done.
Diagnostic enquiries start from $60; the vehicle, symptoms and agreed test scope determine the fee before the visit. This is not a promise of unlimited testing or a confirmed diagnosis.

Tell me your car and what it needs.
A check-engine light is information, not a verdict. It means the computer logged a fault code, and that code points to a system, not a specific broken part. The light alone can't tell you whether you're looking at a $40 fix or a $1,400 one. That's the whole job: reading what the car is actually telling you before anyone touches a wrench.
Diagnostic visits are by appointment at a safe, permitted work area. Send the vehicle, symptoms and warning lights first. Supported module access and tests depend on the vehicle and equipment; complex electrical, immobilizer and programming work may require a workshop. The agreed fee covers the agreed assessment, even if further testing or referral is needed. A separate second-opinion assessment reviews an existing repair recommendation under its own published scope.
The big one. I pull every stored and pending code, read freeze-frame data from when the fault tripped, and trace it to the actual cause, fuel trims, sensor readings, the works. You get the real answer, not a parts-cannon guess.
Scope and fee agreed firstABS and traction-control faults live in their own module that a basic code reader can't even see. I scan the ABS module directly, wheel speed sensors, the pump, tone rings, and tell you why the light's on.
Scope and fee agreed firstAn airbag light means part of your restraint system is offline, it might not deploy in a crash. SRS coverage must be confirmed for the vehicle. Codes guide further testing; a warning light alone does not establish which restraint component has failed.
Scope and fee agreed firstCrank-no-start, dead-no-crank, parasitic battery drain, lights and windows acting up. I test the actual circuit, power, ground, signal, instead of throwing a battery or starter at it and hoping.
Scope and fee agreed firstMisfire, stalling, rough idle, hesitation, no power. These leave a trail in live data, misfire counts per cylinder, fuel trims, O2 response. Supported data helps identify the next tests; a confirmed cause may require further testing or workshop referral.
Scope and fee agreed firstThe hard ones, the light that comes and goes, the stall that only happens warm, the gremlin no shop could pin down. I capture freeze-frame and live data to catch what a quick code-read misses.
Quoted on-site1. Scan. Read supported stored, pending and permanent fault states, freeze-frame data and readiness where available. Generic readers can also show pending engine codes. Enhanced ABS, SRS, body and transmission access varies by vehicle and tool, so coverage is checked before accepting the visit. Codes are clues, not a guaranteed diagnosis or proof of when a fault began.
2. Live data & active tests. Codes are a starting point, not the answer. I watch live sensor data with the engine running and, where the tool supports it, command components directly, cycle a solenoid, fire an injector, test an actuator, to confirm what's actually failing instead of guessing from the code alone.
3. Pinpoint the real cause. I trace the fault to the specific component or circuit. A code that says "lean bank 1" could be a vacuum leak, a weak fuel pump, or a dirty MAF sensor. The agreed assessment tests the vehicle-specific possibilities; unresolved faults may need further testing or referral.
4. Flat quote before any repair. You get a clear, flat price for the fix, parts and labour, before I touch anything. No HST, no surprise line items, no "we found a few other things." If you want to think about it or shop the price, that's completely fine.
5. The diagnostic fee rolls into the repair. If you have me do the repair, the diagnostic fee comes off the bill, you're not paying twice. And a repair concern remains covered by the applicable written workmanship warranty; contact Fares for review.
A mobile assessment can avoid a workshop drop-off when the vehicle, fault and safe work area are suitable. Describe the symptoms first so Fares can confirm what can be assessed on site and what needs workshop equipment. Attendance and a completed repair are not guaranteed by sending an enquiry.
A fault code identifies a monitored condition, not a guaranteed failed part. P0420 means catalyst-system efficiency below threshold. Diagnosis may involve checking exhaust leaks, sensor signals, engine operation and catalyst performance using the vehicle-specific procedure. Neither a converter nor an oxygen sensor should be replaced from the code alone.
Same story with a misfire. A P0301 tells you cylinder 1 is misfiring, it does not tell you why. That could be the ignition coil, the spark plug, a leaking or clogged injector, a vacuum leak, or low compression from a mechanical problem. Six different causes, six very different price tags, one code. The only way to know is to test each one, swap the coil to a different cylinder and see if the misfire follows, check the plug, watch the injector, run a compression test.
This is exactly why parts-store "free code reads" cost people money. They hand you a printout that says "P0420" and you walk out thinking you need a converter, so you buy one, or a shop sells you one, and the problem isn't fixed. Throwing parts at it is the number one way people overspend on car repairs. Agree the diagnostic scope and fee first; codes alone do not justify replacing a part.

“Fares did some major repairs on my GTI, including brakes, rear main seal and transmission fluid change. He is professional, capable and courteous. Despite the terrible weather he persevered, and got the job done. Very happy with his work.”Google review, five stars, August 2026
“Fares came by and did the brakes on my 2021 Lexus RX350. I got quoted way more at a shop so I decided to try a mobile mechanic instead. He showed up on time, did the work in my driveway, and everything went smoothly.”Google review, five stars, 2021 Lexus RX350
“Wonderful and quick experience, charged me way less than the dealer and he did the work in my driveway in the cold. I really appreciate all the hard work.”Google review, five stars
