Hi, anyone does know where the above part is as i get this code on a v6 tdi audi a6 from 1998 . Had a faulty injection pump controler(pump's electronics !) and replaced the module from a known good pump(could not be bothered to replace whole pump). Now, i dont get the faulty module switch code anymore, just the one above ! Engine code AFB... No other codes logged in the memory, but the engine would not start ! Cheers. Does anyone has a ve44 pump diagram by any chance ?
