I have successfully coded my car with VCDS for a number of small tweaks.

I have done some research but found nothing model specific - tried accessing modules 09 and 20 using security access codes 20113 and 31347 to no avail.

Anyone found anything relevant to coding HBA always on (or able to memorise its last status)? I have managed to change the feature on speed via VCDS but not managed to access the mentioned modules.

A different access code? A different route?

Any help would be greatly appreciated - thanks in advance
