Picked up the Q7 this morning, after my 2nd trip today the MIL set off. scan shows the fault occurred 10 mins after i drove away from dealer. P20E9, adblue system pressure too high.
Left the dealer a voice mail, but for now will clear it and see if it returns. If it comes back...back to the dealer it goes to fix whatever is causing it..
