Did my cambelt change a couple of weeks back.... all went well and whilst under the car i pulled the sump off too to give it all a good clean out and make sure the strainer was nice and clear which gladly it all was.... however after 1 day i started getting a sensor error on the the dash... a picture of an oil can with the word sensor next to it.... the strange thing is... as soon as i pull the bonnet release it goes away... if i then close the bonnet and restart the engine it will come back on... pull the bonnet and off it goes again.... i've looked for any trapped wires around the bonnet closure but can't see anything.... i'm not worried about it as it's abviously some sort of wiring issue rather than a true engine fault but it is a little annoying none the less... has anyone suffered anything similar ???
