Fault codes referenced in this manual

Every diagnostic trouble code that appears anywhere in the manual. Where the document gives the code its own parenthetical gloss — and it does for most of them — that description is used; otherwise the sentence it appears in is quoted. VAG five-digit fault text is given where the manual states it.
