Hi. Purchased Astra GS five weeks ago. Sensors showing boot and doors open started showing. Took it to local garage who identified 9 plus sensor problems. Advised to go to garage where bought who then arranged with Vauxhall dealership to look at. Taken nearly 3 weeks . Dealership say possible sensor problems gone after recjecking over short 3 drives but want a longer drive to check if they come back. Has anyone else had these problems with sensors? Car is 1 yr old. Condensation identified as jet washed car with water being absorbed through plasric. LED lights apparently are cold therefore condensation occurs. Again has anyone else had this problem. Car only done 4000 miles.
