no probs and happy to help
ref the codes , some of them may be old ones that don’t relate to what u have now, so indeed best to scan them first , write all of them down, clear and then rescan as that will then show the current fault codes
but I’ve always written down old codes just in case, sometimes there’s pages of them as they’ve built up over the years and not been cleared
Indeed, Plse let us know what u find and plenty of us here to help u all we can , these are complicated beasts so sometimes it’s not always straight forward
plus may i ask how handy are u with a spanner etc , do u do ur own work plse , please don’t ever think where trying to be disrespectful just guiding u according to ur experience
hope that helps
