**Update**

Just got back from recalibration.... In a nut shell...

Initially they were confused as the mirror was not reflecting the laser and double checked the sensor as it was not giving any errors.

Turns out... after resetting up, the sensor was so far out of alignment it was shooting the laser pointer on the wall behind the grid.

He was bewildered that the device was not bringing up any errors. They won't certify the work though as they believe the device is faulty as it is not registering any alignment errors. So will drive and see.

He was saying if I replace the sensor it may also rectify the issue? I think he said the brand is TWR? Though I have to buy a new device as it has to be coded to my car? Is this correct as I think they are $$$ or can I get one from a wrecking yard or any other options?

Thanks

Pete
