B7 TDI tyre pressure and ESC lights on

Hello all, my 1st post. I seem to be a VW nut at present with Audi's A8 and Allroad and Passat's TDI's 07 B6 and 13 B7 - and a Sprinter RV. I bought the B7 with a few known issues. Have replaced the clock spring, 2 rear ABS sensors, brake pads, all filters and oil, battery and a few bulbs and body cosmetic things. The remaining issues are the ESC and tyre pressure lights remain on. As far as I know the tyre pressure issue is probably triggering the ESC issue (light). My model doesn't have wheel sensors, I think the tyre pressures are gauged by the wheel speed sensors. How can I diagnose the issue or fault here (if any)? Can it be that the replaced wheel speed sensors need to be coded in. I don't have a tyre pressure clear button anywhere, my tyres are all good with same pressures. Any help appreciated. Thanks Errol

You need a fault code system such as VCDS.

What year and model is it.

I have a 2013 B7 which has tyre valve sensors.

Recently had an abs sensor go TU and that brought up the Engine management and TPS warnings. Once replaced after a few mile drive both went out.
