Collision sensor

[Bobsuthe]

3 times now my grandland wouldn't start first thing in the morning dash saying collision management fault, waited 10 mins then starts, been in garage but they cannot find any fault, a friend says it could be morning dew on the collision sensor, is this right? Any help much appreciated

It does sound like a moisture issue most likely on the connector or just a poor connection somewhere. Faults like that are a pain as hard to find - I did not realise it would not start if there is a fault! It is not a connector you can either try blowing some hot air on with a hairdryer or a bit of WD40 as not easily accessible for DIY I believe.
