Ford P0011 — VVT 'A' over-advanced Bank 1 on Ford — Ti-VCT solenoid sludge or wet-belt damage on 1.0/1.5/1.6 EcoBoost and 1.6 Ti-VCT. Typical UK independent garage cost: £90–£2400.
What actually causes P0011 on a Ford
Ford P0011 on Ti-VCT is the VVT solenoid sticking with dirty oil. On EcoBoost it's also commonly an early wet-belt symptom — debris affecting cam timing. Service history dictates approach.
Ford engines that log P0011
- 1.0 EcoBoost
- 1.5/1.6 EcoBoost
- 1.6 Ti-VCT Sigma
- 2.0 Duratec HE
How we diagnose P0011 on a Ford
- Check service history for wet-belt change
- Activate VVT solenoid via FORScan
- Inspect oil for belt debris
- Fresh oil and filter after solenoid
The common misdiagnosis to avoid
Replacing the solenoid on a high-mileage EcoBoost without checking the wet belt is asking for a comeback within months.
Ford P0011 repair cost in the UK
Expect £90–£2400 including parts and labour at an independent garage. Main-dealer quotes on Ford are usually higher for the same job, and the spread exists because the cheap cause and the expensive cause throw the same code — pay for the diagnosis before you pay for parts.
Service campaign / TSB note
Ford revised 1.0 EcoBoost wet-belt interval down to 100k/10yr.
