Consumer Complaints for this DTC

2006 VOLKSWAGEN PASSAT with 80000.0 miles

Started vehicle in normal fashion, noticed large amount of vibration from engine compartment, check engine light came on. Upon acceleration, vehicle hesitates drastically. Took to vw service center and they ran diagnostics. 3 fault codes - po300 multiple cylinder misfire detected, po304 cylinder 4 misfire detected, P3073 throttle transfer pump electrical malfunction in circuit. Vw service center swapped ignition coils and plugs - duplicated faults. They wanted to put in new injectors, exhaust lifters, exhaust rockers and fuel pump control module for $1800.00 - and since they were already in there, they wanted to replace timing belt, tensioner, and water pump for another $340.00 i was told that if i don't mind the bad performance/hesitation then it won't hurt the engine any more then it already is. This is a 2006 vw Passat 2.0t lux with 80,000 miles. Crazy that all these problem occur just after the 75,000 warranty was up.
