EPC light on (VW/Audi)
An EPC light on a VW or Audi stands for Electronic Power Control — a fault somewhere in the throttle or engine management system on VW-group cars. The car often protects itself by dropping into reduced-power 'limp' mode, and the traction control can be involved too. Show SightLine the dashboard and it helps you judge whether a gentle drive to the shop is OK or whether this one should not be driven at all.

Steps to fix epc light on (vw/audi)
- Know what it means: EPC stands for Electronic Power Control, and on VW-group cars it signals a fault in the throttle or engine management system.
- Notice how the car responds: EPC often puts the car into reduced-power limp mode to protect itself, so sluggish acceleration with this light is the car doing that on purpose.
- Use the rule of thumb: if the car responds normally, driving short distances gently to a shop is OK — if it hesitates, surges, or idles roughly, do not drive it.
- Watch for the traction control light coming on alongside EPC — the systems are linked on these cars, so both lighting up together still points back to the same fault.
- This app cannot read your car's trouble codes — there is no scanner plugged in — so it never guesses the exact fault; a VW-capable shop scan pins it down.
- When in doubt, do not drive — an EPC light with rough running or lost power means have it towed to a mechanic rather than pushing it.
Safety first: DashRead has no OBD scanner, so it never reads or guesses a trouble code — it works from what it can see and what you tell it. A red oil-pressure, temperature, or brake light, or a flashing check-engine light, means stop now. When in doubt about whether it's safe to drive, don't drive — see a mechanic.
