2004 V6 Treg will start and run for approx 10 sec. Then absolute dead stop. Turn the key off / back on / restart / same thing always. Now if this was a GM vehicle I would say fuel relay or fuel pump without a doubt. Not sure about the treg. Any ideas?
So I"m now believing that there are two fuel pumps on each touareg. With the one under the rear seat passenger side to be the secondary one. Now is the second (main) located under the seat as well, just on the opposite side. Is there a test that I should perform to determine which if not both are at fault.
There are four fuel pumps. Left is the main fuel pressure pump, right is the secondary pressure pump and there are two lift pump that equalize fuel level between the two saddles of the fuel tank.
The left side access cover contains the fuel filter and the right the fuel pressure regulator. Both are located under the rear seats and you must remove a metal cover for access. You can disconnect each pump in turn for testing.
The right pump only operates at certain times, eg-for approx 30 seconds after start up and under some full throttle conditions. You really need to test for fuel pressure and volume which is often overlooked.
Just had the same issue last week.. Picked it up today, set me back $700. Should have done it myself; could have saved me $400. Replace the main fuel pump as other replys already suggested (left one)..
So I took my 04 V6 to the dealer to get the fuel pump replaced. Picked it up yesterday; checked their work and it appears they cut holes in my carpeting under the rear seats to access the metal covers to the fuel pumps.. Seems like a total butcher job to me. Anybody else have the same thing happen? not sure if I'm being unreasonable to get them to either fix it or give me my money back ex parts cost.
My 04 V6 died on the hiway. At 70mph it started slowing down then down shifting and went dead! On the side of road it would start but die in 30 seconds. To start it took many cranks and stopped firing up. Sounds like fuel pump? I have been smelling gas too. I looked under the rear passenger under-carriage and see lots of gear oil. What can this be about?
