Swirl flap actuator circuit open.
P2008 — also written P2OO8, P 2008, 2008 — is the OBD-II code for intake runner control circuit open (bank 1). Same code, same fix: this page covers every spelling of it.
This code means the ECU can't 'talk' to the solenoid that operates your swirl flaps, usually because the solenoid coil has fried or the wiring has snapped. It's a classic plague for Ford Mondeo and Focus petrol owners.
P2008 is a engine fault code, typically costing £150–£700 to put right in a UK garage.
What P2008 actually feels like to drive
- The car feels 'flat' or gutless when you try to overtake, especially above 3,000 RPM.
- Engine Management Light (EML) is glowing on the dash, sometimes flickering under heavy load.
- Fuel economy has taken a proper dive—you'll notice you're getting 5-8mpg less than usual.
- Idle might be slightly hunting or 'lumpy' when you're sat at the lights.
- On the Ford Mondeos, you might hear a faint clicking or tapping sound from the intake area.
What causes P2008?
- Failed actuator
- Wiring break

The P2008 misdiagnosis that wastes money
I’ve lost count of how many times I’ve seen brand new intake manifolds or swirl flap kits fitted by DIYers or back-street shops, only for the P2008 to stay firmly on the dash. Everyone blames the flaps themselves getting gunked up, but on the Ford Duratec engines especially, it’s almost always the little vacuum solenoid valves sitting on top of the manifold. People spend £400 on a manifold when a £40 Pierburg solenoid or a simple broken wire near the plug was the actual culprit. Don't assume the flaps are stuck until you've tested the circuit.
What a UK garage should charge for P2008
A basic diagnostic plug-in will run you £50 to £80 depending on where you live. If it’s just the vacuum solenoid (common on Fords), you’re looking at about £45 for a quality Pierburg part plus an hour's labour, so roughly £120-£150 total. However, if the actuator motor is built into the manifold (like on some Audis or Vauxhalls), the part alone can be £300+, and with 3 hours of labour to swap the manifold, you could be staring down a £600-£700 bill at an independent, or over a grand at a main dealer.
P2008 repair cost in the UK
Most P2008 repairs land between £150–£700 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 P2008
If you're taking this to a garage, ask them to 'load test' the wiring to the intake runner solenoid, not just check for 12 volts with a multimeter. A multimeter can show 12V even if there's only one tiny strand of wire left, but that won't be enough to pull the solenoid. If you drive a Mazda or a Ford, tell the mechanic to check the vacuum lines for cracks while they’re at it. A tiny split in a rubber hose can mimic an actuator failure, and that’s a £5 fix versus a £300 one. Insist on a vacuum pump test before they start tearing the top of the engine off.
Can you drive with P2008?
