Hi,
The amber engine fault light on my 2018 Velar D300 came on at the weekend. No sign of anything unusual when driving. Plugged in an OBD to check the diagnostics and found a fault code P0234 suggesting a turbocharger overboost fault. I’ve reset the code to clear the dash fault light and hoping for the best before finding a slot at the local garage to get it checked out,
Wondering if anyone has experience of similar problems!

Thanks

Nope, no details at all. I bought an ODB diagnostic tool (£20 on Amazon) plugged it in and reset the falut code. Driven the car for over 250 miles since and has returned 🤷‍♂️.

Yeah think I'll purchase one myself, do you have the link to the one you purchased?
AA advised a technician look at it so have one coming tomorrow morning, will see what he says and advise you of what gets said

Cheers for that,

So I have the technician here, who's told me the code is due to a flap getting clogged up and sticking and also there is a sensor close by to it that could also be dirty, they did used to replaced the part on warrenty but now they've been told if it's due to it been clogged up then to just clean them out, he said it's a common thing on cars that have done a fair few miles, mines currently at 45k miles. So he's going to clean that for me said it should take half an hour.

Worth mentioning my engine light went off yesterday whilst driving which I mentioned to him today and he told me it will come back on at some point once that flap starts to stick again so if you do see it come back on again since you reset your light you know why 😁

Hope that helps bud, thanks for the link
