2005 A4 3.0 Quattro Tiptronic

P0014 - B camshaft position - timing over advanced or system performance - bank 1

Timing belt, water pump, etc replaced in October. In April the water pump goes taking the timing belt with it. Exhaust valves were bent as well. The shop warrantied the failure, replaced everything. The car runs great, but now the CEL comes on. Autozone pulled the code using VW as the closest match. The shop reset the CEL, but now its back. Does anyone know the possible causes for this?

Thanks!
