Audi Computer Diagnostics (VCDS / ODIS)
We read every control unit in your Audi with genuine VCDS or ODIS equipment: engine, transmission, brakes, airbags, and air conditioning, with live operating values and a written report within 90 minutes.
Audi computer diagnostics is a full scan of every electronic control unit in the car with genuine VCDS or ODIS equipment.
The scan finds the cause of any warning light or hidden fault before we open a single mechanical part, and it produces a written report listing the code, the affected unit, and the recommended fix.
We read every Audi control unit — engine 01, transmission 02, ABS 03, airbags 15, air conditioning 08, and more — not just the engine unit the way generic OBD tools do.

When do you need Audi computer diagnostics?
You need the scan the moment any warning light comes on: Check Engine, EPC, the gear-lock light, ABS, or airbag — each light stores a code in a specific control unit, and reading it identifies the cause before any guesswork.
- Check Engine light
- Code in engine unit 01 — identifies the affected cylinder or sensor
- EPC light
- Fault in the electronic accelerator pedal or the turbo boost system
- Gear-lock / limp-home light
- Code in transmission unit 02 that stops normal shifting
- ABS light
- Code in brake unit 03 — a speed sensor or the pump
- Airbag light
- Code in airbag unit 15 — disables deployment in a crash
- Weak AC cooling with a warning
- Code in air conditioning unit 08 — refrigerant pressure or a temperature sensor
What do we check?
We check every control unit in the car: engine 01, brakes ABS 03, transmission 02, airbags 15, and air conditioning 08, and we read live operating values for each unit — engine RPM, transmission temperature, refrigerant pressure — not just stored codes.
- Unit 01 — Engine
- Codes, live values (RPM, temperature, lambda), sensor status
- Unit 02 — Transmission
- Codes, clutch values and oil temperature in DSG/S-tronic gearboxes
- Unit 03 — ABS brakes
- Speed sensor codes and the ABS pump
- Unit 08 — Air conditioning
- Refrigerant pressure, evaporator temperature, compressor operation
- Unit 15 — Airbags
- Deployment system readiness and crash sensors
- Live operating values
- Direct readings while the engine runs, not just from memory
What is the difference between VCDS, ODIS, and generic OBD tools?
Generic OBD tools read only the engine unit through a standard port, with generic codes rather than detailed ones. VCDS and ODIS are genuine Volkswagen Group diagnostic tools that read every control unit and can also code and adapt settings.
A generic OBD tool connects to the car's port and shows generic codes like P0300 without unit details or live values. That's enough for a quick check, but it won't catch transmission, airbag, or air-conditioning faults.
Independent technicians use VCDS, which reads every unit from 01 to 75 and codes basic settings. ODIS is the Volkswagen Group's own original tool, and we use it for the latest coding jobs and software updates that some newer Audi models require.
How does a computer diagnostics session work?
We connect the VCDS or ODIS tool to the diagnostic port, read every unit and its live values, run a road test when needed, then hand you a written report with the codes, their causes, and the repair cost — the whole session takes 90 minutes from connection to handover.
Connection and full scan
We connect VCDS or ODIS to the OBD port and read every control unit in one pass.
Live operating values
We record live values for the engine, transmission, and air conditioning during actual operation.
Road test when needed
A test drive confirms intermittent faults that only appear while the car is moving.
Written report
We document every code, its unit, the likely cause, and the recommended fix, within 90 minutes of starting the scan.
Which codes do we resolve with this scan?
We resolve hundreds of codes every day across every type: P0299 for weak turbo boost, P0016 for camshaft-crankshaft timing misalignment, and EPC codes in the accelerator pedal system — every code ties to a specific control unit and a known fix.
- P0299
- Weak turbo boost — charge pressure below the required level in engine unit 01
- P0016
- Camshaft-crankshaft timing misalignment — the timing chain or its sensors
- EPC light code
- Fault in the electronic accelerator pedal or the torque control system
Does the scan cover every Audi model?
Yes. We scan every Audi model with the same VCDS and ODIS tools, from the compact A3 and Q3 to the large A8, Q7, and Q8, and even the electric e-tron with its dedicated battery control units — every model has its own full maintenance page.

How much does Audi computer diagnostics cost?
A full scan of every unit with a written report runs from 150 SAR to 250 SAR, and code reading with a diagnostic road test falls in the same range — the final price depends on how many units are affected.
| Service | Indicative range (SAR) |
|---|---|
| Full computer scan (all units + report) | 150 – 250 |
| Code reading + diagnostic road test | 150 – 250 |
| Pre-purchase inspection (computer + body + road test + report) | 350 – 500 |
Why choose our computer diagnostics?
Our eight Volkswagen Group-certified technicians use genuine VCDS and ODIS every day, never generic imitation tools, and they explain every code in a written report before any repair — then we code the fix with the same equipment.

Where do we offer computer diagnostics in Riyadh?
Our workshop sits on King Abdulaziz Road in Olaya, and we cover every district of Riyadh, from Al Naseem in the east to west Riyadh. Our mobile service brings the diagnostic tool to your car, and we tow it in when an emergency light comes on.
- Does the computer scan catch every Audi fault?
- It catches every fault tied to an electronic control unit, covering 90% of faults on modern Audi models. Purely mechanical faults, like an oil leak from a gasket, still need a visual inspection after the code reading.
- How long does Audi computer diagnostics take?
- 90 minutes for the full scan of every unit with live operating values and the written report. Reading codes alone, without live values, takes less time.
- Does the scan clear the code, or just diagnose the cause?
- We read the code and explain its cause in the report first. Clearing a code without fixing its cause brings the light back within days, so we pair it with a repair plan with a clear price.
- What is the difference between this scan and a pre-purchase inspection?
- Fault diagnostics focuses on diagnosing a code or light already present in your current car. A pre-purchase inspection adds a body inspection and a full road test for a car you're considering buying.
- Do you code the car after reading the codes?
- Yes. We clear the codes and re-code the affected unit, or adapt its settings, with VCDS or ODIS as part of our Audi coding service once we've identified the cause.
- Does the scan work on every Audi model, old and new?
- Yes. VCDS and ODIS cover Audi models from the older B6/8P generation to the modern electric e-tron with its expanded control units.
