ok on your vehicle this may be a compounded issue.
the first thing you need to do is to replace the 409 relay under the dash. you need to get from the dealer 1J0 906 383C relay.
once that is done then clear the faults and then test drive to see if any of the codes come back. the majority of the codes are short to ground faults and the 409 relay controls that issue. the relay is about $50 range . this may cure all of your faults !!
