    1. 02-04-2012 07:48 PM #1
      i have a 2009 cc with 56k and i recently was driving the car and it completly shut off. i tried to start it and the car was acting like it had no gas. finally 10 mins later it turned on and ran. the check engine light came on and the codes where

      12355 fuel pump mechanical malfunction p3043 intermittent
      00135 fuel rail/system pressure too low p0087 intermittent
      12356 fuel pump short circuit p3044 intermittent

      i replaced the fuel pump located under the back seat and im still having the same issue. what is it??

      It sounds like you have a problem with the mechanical high presure fuel pump, which is mounted on the engine, on the end of the head, near the battery. Or the pressure sensor on the high pressure fuel rail is defective.

      You have a 5 year or 60k miles Powertrain Warranty from VW.

      Fuel system should be considered part of the Powertrain as its Chain Driven on the CC. call you local VW dealer.

      Check the connector and wiring to the fuel pressure control solinoid (part of the high presure fuel pump). If the connector and wires seem OK, pull the connector off and measure the resistance of the two pins on the pump. It should measure somewhere between 25 and 35 ohms. The solinoid might be open or shorted.

      I have the same model as yours with the same problem same fault codes, the Authorized Dealer can't seem to figure out whats causing it, they opened up a case help tech line with volkswagen and submitted all the data to Volkswagen Tech Support and so far nothing, not even Volkswagen can't figure it out, I was wondering did you get a solution for your problem?

      I had the same issue. The dealer replaced the fuel pump and that didn't fix it. They figured out it was the fuel pump relay.

      Back from the dead... Same codes on my wife's CC that left her stranded today. 86k on the clock.

      The other code that I had in addition to what was posted is:

      004506 - Fuel Pressure Sensor (G247)
      P119a - Malfunctions - Intermittent
      Fault Frequency = 1

      on P3043 Fault Freq = 5 as well as P0087 (Rail Pressure)

      ..sigh ...Time to Start digging

      What the heck is going on with these codes, I have the same codes on my 09 VW CC P3043: Fuel Pump Mechanical Failure, P0087 : Fuel Rail Pressure Too Low, P3044: Fuel Pump Short Circuit, My car looks like its on the showroom floor, but id rather be driving it than it sitting in the garage , its over an $800.00 repair job that should not be, I traded in a 98 Honda Accord with way more mileage that this and it drove like a charm, I want back my Honda,or VW needs to recall and repair this lemon cause I cant make lemon aide!!!!!!!

      I'd swap the relay first since it is easy (may be able to swap with a know good one on the panel to test), then the sensor, then the pump. Pump is about a $300 part and maybe an hour to replace.

      I will start the trouble shooting now that I know where to start, My CC has been in the Garage for over 2 months,will the Relay give all the P-codes ?
