P0335 on Opel by model: symptoms, diagnosis and fix
The Renault-sourced R9M 1.6 BiTurbo CDTI used in Vivaro B (and Renault Trafic III) develops timing chain stretch, typically 100,000-180,000 km. It starts with cold-start rattle and misfire codes, and the chain can then skip and cause valve damage. It is particularly bad on stop-start fleet use without regular oil changes.
Common Symptoms
- cold start rattle
- misfire
- loss of power
- engine warning
How to Fix
Fit a full chain kit (€1,200-€1,800) including chain, guides, tensioners and sprockets. The job often involves dropping the engine in vans due to tight clearance, which raises the total cost. Use C4-spec low-SAPS 5W-30 oil and shorten intervals to 15,000 km max for fleet/stop-start duty.

Frequently asked questions
What does P0335 mean on a Opel?
P0335 stands for "Crankshaft Position Sensor A Circuit Malfunction." This code means the engine computer has lost or detected a faulty signal from the crankshaft position sensor (sensor A), which tells the computer exactly how fast and in what position the crankshaft is rotating. That signal is essential for timing the spark and fuel injection, so a problem here can cause hard starting, stalling, or a no-start condition. The computer sets this code when the crank sensor signal is missing, erratic, or out of its expected pattern. Causes range from a failed sensor or damaged wiring to a problem with the reluctor (tone) ring the sensor reads. On Opel it is documented across 1 model: Vivaro.
What are the most common causes of P0335?
The most common causes of P0335 are: Failed crankshaft position sensor, Damaged, corroded, or loose sensor wiring/connector, Metal debris or oil contamination on the sensor tip, Damaged or misaligned reluctor (tone) ring, Excessive air gap between sensor and tone ring, Wiring shorted or open in the sensor circuit, Faulty PCM/ECM (rare). The specific cause varies by vehicle.

Published repair estimates on Opel range from $1,200 to $4,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
