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.
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.
Bob's workshop tip
EcoBoost P0011 — solenoid + belt-condition check. Don't skip the belt question.

Reading P0011 on a Ford properly
A generic reader will show P0011 and nothing else. What matters is the freeze-frame data stored with it — engine speed, load, coolant temperature and fuel trims at the moment the fault was logged — plus whether any other module on the Ford has logged something at the same time. Codes rarely arrive alone, and the order they were stored in usually points at which one is the cause and which are the consequences.
Clearing P0011 without fixing it
Erasing the code resets the Ford's readiness monitors as well as the light. The fault returns on the next drive cycle if the cause is still there, and in the meantime the incomplete monitors can stop the car passing an emissions check. After a genuine repair, the car is driven until the relevant monitor completes before it is handed back.
