Can anyone tell me how extensive the coverage of the urQ is in the Bentley's shop manual "Audi 4000S, 4000Cs and Coupe Gt : Official Factory Repair Manual 1984, 1985, 1986, 1987 : Including Quattro and Quattro Turbo" ? Is Bentley's the bible (as it is for the CQ) and does this one also apply to the `83 urQ ? Regards, Rick Zehr
