High Pressure Fuel Pump Replacement for AUDI A3 TT VW Golf GTI Jetta Tiguan - 06H127026B

cant give zero stars.. this pump was bought as a replacement for a physically damaged pump. the original hpfp had a broken plunger shaft. no issues prior the shaft breaking. after changing the hpfp, check engine light with code p2293 was present, vehicle in limp mode. the pump was metered at the solenoid and tested at .20 ohms(same as OEM original part). voltage was checked going to the pump solenoid and tested good. upon removal of fuel lines, it was apparent that fuel pressure was not building with this pump.Replaced this hpfp with a much more expensive Bosch pump from Deutche Auto and everything is back to normal, no power loss, hesitation, slow starting, check engine light, etc. lesson learned.
