P0353 means the ECU saw an electrical fault in the coil 3 primary or secondary circuit. Usually a dead coil-on-plug, sometimes wiring or connector corrosion, rarely the ECU driver itself.

P0353 is a ignition-related diagnostic trouble code classified as moderate severity. When your vehicle's ECU detects this condition, it stores P0353 and illuminates the check engine light.
If your vehicle has triggered P0353, you may notice one or more of these symptoms:
Here are the most common causes of P0353:
No - address this immediately. You can limp home, but don't keep driving on it. Raw fuel dumping into the exhaust from cylinder 3 will destroy your catalytic converter within a few hundred kilometres, and that's a €600 to €1,500 mistake.
Follow these steps to pinpoint the root cause of P0353:
Repair costs for P0353 vary depending on the root cause and your vehicle. Here are typical estimates:
Prices estimated as of March 2026. Costs vary by region, vehicle, and shop.

Yes, and it's the fastest free diagnostic you can do. Move coil 3 to cylinder 1, clear the codes, drive for 10 minutes. If the misfire follows the coil to cylinder 1 (P0351), you've confirmed the coil is bad. If P0353 comes back, the problem is in the plug, wiring, or ECU.
If your car has over 150,000 km on the original coils and one has died, the others are on borrowed time. Replacing all of them costs more upfront but saves you repeat labour. On a 4-cylinder that's usually worth it, on a V8 with coil-on-plug it's a judgement call based on budget.
A flashing CEL means active misfire severe enough to damage the catalytic converter. Pull over as soon as it's safe and don't drive on it, because continued driving with a flashing light can overheat and ruin the cat quickly.
Expect noticeably worse consumption. One dead cylinder means the others work harder, and the oxygen sensors see unburned oxygen from that cylinder and read lean, so the ECU adds extra fuel trying to compensate.
A coil in the 20 to 40 euro range from an established supplier is normal for an older car. On German cars and turbocharged engines, fit an OE or OE-equivalent part: the coil works harder there and a marginal one shows up quickly.
A 15 euro Bluetooth adapter and a free phone app read the exact fault code a shop charges 30 to 100 euros to pull. Here is how to do it yourself in 5 minutes.
A flashing check engine light means the engine is misfiring right now. Pull over and read the code: the fix is usually $80 to $400, the delay costs $1,500 up.
