So picking up a caravan from the Lake District in a couple of weeks. Tow bar needed, Lexus want over £1k, err no thank you. Take to an independent, job done fine, but oh no. Parking sensors now throwing a fit🙄 'Not us guv, just a coincidence, honest, we've checked it all over' hmm.
So this morning stripped the entire boot out, cleaned and reconnected all the bits, including the sensors, and after two hours all working again👍 two clips missing from the wheel arch liners each side, which might explain small amount of water present in corners of the boot so off to get replacements. Trouble is however good a job done, it seems there are always bits missing or clips left lying around. Not good. Anyway proper job done now and feeling good about getting it sorted.
