Hi, I’ve had a Tiguan for 3.6 years off the scheme, and yeah they ping happy ain’t they.
Tbf they diagnosed the issue with us and turned out to be the steering wheel. It was probably replaced 6 months ago and it’s been fine since thank god. We actually got so used to it we kind of ignored it. But I know a few people that own relatively new VW’s and they all complain about warning sounds!!!
A thing we did was record the pinging when driving let’s say up the motorway. So my partner would get her phone put and video it, so I could show the dealer what was going on.
It was actually the outer skin on the steering wheel that was causing the issues, but they replaced the whole wheel.
Good luck
Ps IF it keeps playing up and VW won’t help you, I’d suggest asking motability about a possible termination on the car, as apparently the Brand New version is coming on the scheme in July. And possibly order one of those. (But wait to see if it comes on first) they don’t make the all space in the new car though. They’re bringing out a new concept to replace the all space
