Evap system purge flow wrong.
P0441 — also written PO441, P 0441, 0441 — is the OBD-II code for evap purge flow incorrect. Same code, same fix: this page covers every spelling of it.
This is usually the purge valve getting stuck open or shut, messing with the engine's air-fuel mix. It's a classic MOT-annoying code often found on Polo and Corsa petrol engines.
P0441 is a emissions fault code, typically costing £80–£400 to put right in a UK garage.
What P0441 actually feels like to drive
- The engine lumpy as hell for a few seconds right after you've filled up at the Tesco pumps.
- A weird, faint ticking noise coming from the engine bay that sounds like a sewing machine.
- The car feels like it's going to stall when you're idling at red lights, then clears itself.
- A faint whiff of petrol around the front wheel arch after a long run down the A9.
- The 'Check Engine' light popping on about 20 miles after you've cleared it.
What causes P0441?
- Failed purge valve

The P0441 misdiagnosis that wastes money
I’ve lost count of how many times I’ve seen brand-new fuel caps and charcoal canisters fitted before the car even lands in my bay. People think 'EVAP' and immediately assume the tank vent or the canister is blocked. In reality, on most VAG and Vauxhall stuff, it's almost always the little solenoid valve clicking away (or not clicking) under the bonnet. I've also had lads spend hundreds on sensors when the actual fault was a £5 bit of perished vacuum hose that had been nibbled by a mouse or gone brittle from engine heat.
What a UK garage should charge for P0441
For a basic Bosch or Pierburg purge valve, you're looking at £40 to £90 for the part. Labour is usually an hour’s 'hook-up and hunt' time, so around £60-£80 at an independent. Total job is usually under £180. If you go to a main dealer like Arnold Clark, they’ll want £150 just to plug it in, and with their OEM markup, you’ll be staring down the barrel of a £350 bill for a valve that takes ten minutes to swap.
P0441 repair cost in the UK
Most P0441 repairs land between £80–£400 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 P0441
If a garage tells you that you need a new charcoal canister straight away, ask them if they’ve done a 'smoke test' yet. If they haven't, they’re just guessing with your wallet. A proper indy should be able to pulse the purge valve using a scan tool to see if it’s actually opening and holding vacuum. Also, check your fuel cap seal yourself—rub a bit of silicone grease on the O-ring; if the light stays off for a week, you’ve saved yourself a £100 diagnostic fee. Don't let them 'parts-cannon' this one.
