If your dashboard lights up like a Christmas tree, don’t ignore it—those alerts are your car’s way of saying something’s not right. At Novo AVS in Kensington, we specialise in diagnosing and resolving EPC lights, check engine warnings, and transmission faults across a wide range of European vehicles: Volkswagen, Audi, BMW, Skoda, Cupra, and Mercedes-Benz.
Whether you’re looking for a Volkswagen mechanic in Sydney, a Bondi Audi specialist, or an Eastern Suburbs BMW service expert, Novo AVS delivers precision diagnostics backed by decades of experience.
EPC Light (Electronic Power Control)
Common in: VW, Audi, Skoda, Cupra, Mercedes-Benz
What it means: The EPC system monitors throttle input, stability control and engine sensors. It may be triggered by:
Faulty throttle body or pedal sensor
Boost leaks or misfires
Wiring or sensor issues related to the drive-by-wire system
What to do: It’s not worth risking potential damage and future issues by ignoring this. If the EPC light is present, you’ll need to get a diagnosis as soon as possible.
Eastern Suburbs Volkswagen mechanic, we use VW/Audi-specific tools (ODIS & VCDS) to scan codes and isolate the root cause.
Check Engine Light (CEL)
Common in: BMW, VW, Audi, Cupra, Skoda, Mercedes-Benz
What it means: It could indicate:
Oxygen sensor or MAF failure
Coil pack or spark plug issues
Carbon build-up (common in direct injection engines)
Vacuum leaks or injector faults
What to do: Don’t ignore it. Especially in turbocharged engines, unresolved CELs can lead to costly wear. If you’re in Marrickville, Bondi, or Alexandria and need a reliable European car mechanic, we’re here to help.
Transmission Warning Light
Common in: VW, Audi, BMW, Skoda, Cupra, Mercedes-Benz
What it means: Points to shifting issues or gearbox wear. Possible causes:
DSG fluid degradation or overdue servicing
ZF gearbox pressure loss
Mechatronic unit failure (common in DSG)
Clutch slip or overheating
What to do: Stop driving if you feel hard shifts or hesitations. As a leading DSG and mechatronic repair expert in Sydney, we provide advanced servicing and reconditioning.
ABS / ESC / Traction Control Lights
What it means: Your braking and stability systems may be compromised. Likely issues include:
Faulty ABS wheel sensors
ESC module or yaw rate sensor failure
Misaligned steering angle sensor
What to do: These are critical safety systems—especially important for Porsche, Mercedes-Benz, Volkswagen and Audi owners in Sydney’s Eastern Suburbs, where road conditions vary. Our factory-level diagnostic systems ensure accurate fault identification.
