Coil 3 fault.
P0353 — also written PO353, P 0353, 0353 — is the OBD-II code for ignition coil 'c' circuit. Same code, same fix: this page covers every spelling of it.
P0353 means the ECU has spotted a physical electrical break or a short in the circuit for the ignition coil on cylinder number 3. It’s a proper 'dead miss' that'll fail an MOT on emissions instantly.
P0353 is a ignition fault code, typically costing £50–£350 to put right in a UK garage.
What P0353 actually feels like to drive
- The car feels like it’s 'chugging' or 'running on three legs', especially when pulling away from lights.
- Engine Management Light (EML) flashing violently when you try to overtake on the A9.
- A noticeable 'pinking' or ticking sound from the engine bay under load.
- Heavy smell of unburnt petrol from the exhaust pipe (because cylinder 3 isn't firing).
- Stop/Start system gives up the ghost and displays a 'Service ESP' or 'Service Hill Start' message on the dash.

The P0353 misdiagnosis that wastes money
I’ve seen dozens of lads rush to Euro Car Parts for a set of plugs or a new coil pack, only to find the P0353 stays put. On the Vauxhall Insignia or the Astra J with the A14NET engine, it’s often not the coil itself, but the pins in the wiring harness plug getting loose or corroded. Another classic is blaming the ECU when it’s actually a 'ghost' fault caused by cheap, non-resistor spark plugs creating RMI interference. Always check the harness for 'green crusties' before spending £100 on a Delphi unit.
What a UK garage should charge for P0353
For a basic Ford or Vauxhall, a diagnostic plug-in should be £40-£60. A quality Bosch or Delphi coil will set you back £50-£90 from a factor like GSF, plus maybe half an hour of labour (£40). Total £130-£180. If you’re at a main dealer, expect to pay £150 per hour labour and £120 for the part, pushing you towards £350. If it’s a BMW N43 and you need all four coils and plugs to be safe, you're looking at a £400 bill at an independent.
P0353 repair cost in the UK
Most P0353 repairs land between £50–£350 including parts and labour. The spread is wide because the cheap fix (a sensor, a hose, a leak) and the expensive fix (a major component) throw the same code — which is why a proper diagnosis before parts are bought saves the most money.
Bob's tip on P0353
If you take it to a garage, ask them to 'swap the coils between cylinders 3 and 1'. If the code moves to P0351, you know for a fact the coil is dead. If P0353 stays, it’s a wiring or ECU issue, and a new coil won't fix it. Don't let them just 'parts-cannon' it. Also, if you’re driving a Ford or a Vauxhall and the coil has failed, change the spark plugs at the same time. A worn plug with a massive gap puts way too much stress on the new coil's secondary windings, and you'll be back in the workshop within three months.
