VANOS fault. What the code means, its most common causes and what to do.
Six-digit BMW codes stored by the engine control unit (DME). The same code appears in this form in ISTA and in the MOSTUNED app.
| Code | Meaning |
|---|---|
| 130713 | VANOS solenoid valve, inlet: Position not reached |
| 130714 | VANOS solenoid valve, exhaust: Position not reached |
| 130715 | VANOS solenoid valve, inlet: Camshaft jammed |
| 130716 | VANOS solenoid valve, exhaust: Camshaft jammed |
| 130709 | VANOS solenoid valve, inlet: Position not reached during cold start |
| 13070A | VANOS solenoid valve, exhaust: Position not reached during cold start |
VANOS is the system that changes camshaft timing using oil pressure. The DME requests a cam angle, the solenoid valve directs oil, and the shaft moves to that position. If the shaft does not reach the requested angle in time, these codes are stored. Intake and exhaust sides are reported with separate codes.
Top to bottom, starting with what is easiest to check.
| Cause | What to check |
|---|---|
| Engine oil | Low oil level, an overdue oil change or the wrong viscosity is the first thing VANOS reacts to. Check the oil first. |
| Solenoid valve | The valve’s screen can clog with deposits; it is cleaned or replaced. |
| Wiring and connector | Oil in the valve connector or a poor contact causes intermittent faults. |
| Timing mechanism | If oil and valve are fine, the VANOS unit and chain side are examined. |
The car mostly drives; low-rpm pull drops and idle may become uneven. Check the oil level straight away and have the cause found.
Tuning does not create VANOS faults; however cam timing is the foundation of torque, and a car whose VANOS is not working properly will not deliver what the tune offers. This is one reason we work on cars with up-to-date oil servicing.

Clearing removes the entry, not the cause. If the cause remains, the code returns when the conditions occur again. The right order is: read the code, fix the cause, clear it and read again to confirm.
You read it for free with the MOSTUNED app: connect your iPhone to the car with an ENET cable or WiFi-ENET adapter and open Fault Codes under Diagnostics. Bluetooth OBD (ELM327) adapters do not provide this connection.
