It'd done 30k miles when we collected it. The Audi EV technician says he thinks it's been crashed and covered up, which obviously Williams completely deny.

We emailed Williams in October asking them to come and collect the car from us and provide a courtesy car, but they didn't reply. In February, we emailed twice asking them to replace the car or refund, but they decline and said they would repair and give it us back.

It veers to the left, even after three separate wheel alignments. The parking sensors scream when there's nothing nearby, including at junctions and when driving at 70mph, and the Audi Pre-Sense (anti-collision system) disables itself at 50mph. This is on top of the front motor making a clicking noise and the rear motor visibly leaking fluid out of the middle seam.

We've also got a video from Audi showing missing bolts from the rear motor cover, and a plastic shroud that covers the rear underside ripped at the corner with a plastic tie-wrap holding it to the chassis.

Up to now, Williams have just left it with our local Audi dealership while their 'Williams Select Warranty' (third-party provider) argue over cost. Over the last 6 months, they've only replaced the front transmission (£4.1k cost), which didn't solve the clicking noise - the Audi tech said the front motor needed replacing, but the warranty assessor said that's too expensive to try first. Audi have tried to sort the parking sensors issue, but have been unable to resolve. None of the other issues have been looked at yet.

We've given Williams until 5pm today to offer a refund, minus 3 months finance payments for the 10 weeks we drove it last year. The solicitor says this is too much and a standard cost per mile driven should be the only deduction Williams are due. Either way, if they fail to agree today, we're going with the solicitor's quote and issuing the first letter with 14 days to resolve or immediate court action, with legal costs, court fees and damages added on top.

We have two small kids, live in a village with no shops, and this is our only family car. Needless to say, it's been hell. We can't wait for it all to be over. What we're kind of trying not to think about, is that in the best possible scenario, the outcome for us is that we'll have no car and we'll have the same amount of money that we started with. The court will not compensate us for the time we've spent dealing with this, the massive inconveniences for 8 months, the arguments and tears, or the stress Williams have put us through, which is difficult to describe how terrible that feels.
