We do not have a full sheet for this code yet, with its causes and checks. What you see here comes from the OBD2 code standard.
System
Engine and transmission (P)
Code type
Manufacturer-specific code: its exact meaning depends on the make.
What do I do now?
If the engine light flashes, the car loses a lot of power, overheats or the brakes fail, stop somewhere safe and call for assistance.
If the car drives normally, book a garage and show them this code: its exact meaning and the cause depend on each model.
Tell us what you notice: the diagnosis takes the code, your car and the symptoms into account.
Where is it on the car?
This code does not point to the engine, the brakes or the transmission: you will see the X-ray car with no area marked.
Related faults in the database
1.4/1.6 VTi chain and ValvetronicTiming / Valvetronic
Engine / equipment
Naturally aspirated 1.4 and 1.6 VTi from the Prince family (EP3/EP6C), including the MINI One and Cooper 1.4/1.6 (N12/N16)
Period mentioned
2006–2017
Symptoms
Chain rattle on cold starts, unstable idle, stalling and an engine light with variable valve timing codes (P1030, P1062, P101A, P1025).
Possible cause described
The chain stretches and the tensioner fails early, often before 100,000 km. A stretched chain throws the timing out and makes the Valvetronic learning fail, which gets mistaken for a Valvetronic fault.
Check for the garage
Listen to a cold start and check the timing and chain condition before replacing Valvetronic parts or repeating adaptations.
Cost cited in the source
Tensioner and chain: approx. €750–1,700 (converted from dollars)A rough figure from the original database, not an up-to-date quote.
Mileage cited in the database: up to 100,000 km. This is not a maintenance interval and does not predict a failure.
