Default Vis motor making strange

After switching the engine KV6 off this evening heard a strange noise whirring noise from the Vis motor which the only way to stop the noise was to disconnect the battery, put the battery leads on after a couple minutes and still making the noise.

Any advice would be grateful.

Malcolm

Hi Malcolm,

Remove the connector from the offending VIS actuator so that you can drive the car.

Purchase a replacement from club member Stocktake.

Hi Simon

Thank you for the prompt, will this cause any problems with driving?

No, not really,

If it's the balance actuator which is faulty, then acceleration will seem rather lack lustre.

If it's the power actuator, you won't notice much unless you floor the throttle.

Before ordering perhaps an unnecessary new one, remove the balance motor and check that the shaft on the flap hasn’t broken.

The power motor has an internal stop but the only thing that prevents the balance motor from stopping is the flap.

Hi,
Vitesse is correct. It is either the flap that has failed or the internal gearing on the vis has stripped . The former is more common. Again as mentioned disconnect the plug to use the car.

Is it fair to say that if the flap has failed, jammed for example, it may have toasted the VIS motor?

if the sound is more of a rhythmic gearing rotating then it is more than likely the flap has failed and the vis is fine but it may need resetting to the correct rest position If the noise is just like a smooth small electric motor running then the gearing in the vis will probably have stripped.
