When changing the wheels the suspension will have obviously dropped much lower than it would do when sat on the wheels.

One of the abs cables could have been damaged at this point.

I have changed my wheels on my Superb to VW turbines and it now runs 235 tyres, all I did with mine was to reset the TPMS and it was good to go.

 

TPMS on this model uses wheel rotation rather than pressure valves, cheaper but can still give issues of its own.

 

 

If only I had your luck haha

So I've borrowed this and it's not picking up any stored codes even though dash has the lights on ?

Those generic obd readers cannot access the abs module unfortunately.

 

See if you can find a local member who has a VCDS cable. That can do a full diagnostic scan of all the modules. There is a thread on here with a map of users, I'll see if I can dig it out.

 

 

Found the link. Have a look and see if you can find anyone near you.
