I need Your Help

I have a sick motor stuck on the drive in Newcastle which needs VCDS to prime the fuel pumps before I can get her started. Can you help?

 

Welcome to the forum.

It depends which Newcastle. Put your location in your User CP along with.

Can I suggest that you add your car spec to your signature as it will save users asking everytime, if you know the engine code that will also be great? http://www.volkswagenforum.co.uk/f26/adding-your-car-spec-5119.html

Sorry

Sorry. It's a rather urgent call for help so I got in touch with you coz you're a mile down the road. The vehicle concerned is a 2007 Audi Q7 3.0 TDI drained of a tank full of 4 star.

 

PM me your location and a suitable time?

Q7 TDI fuel filter

 

Keith. Your a gent. I'm available any time to suit you. I'm at ST5 2JE house number 7. Cheers

 

If there is someone there all the time I'm coming over now, put the kettle on or cool a beer.

 

Sorry I couldn't help you more with getting your Q7 running.

Without going into all the details of why you need the pump running.

He wanted the fuel pump running to bleed the system. I did an Autoscan first just to check there is nothing else causing it not to run. There were 15 systems with faults the only one for the engine was:

VAG Error Code: 17471
EOBD II Error Code: P1063

Fault Location:
Fuel Pressure - Control Limit not Reached

Possible Cause:
Air in fuel system.
Fuel system leak.
Fuel lift pump.
Fuel bypass valve.
Fuel pressure control valve.
High pressure fuel pump.

I went into Engine can clicked OutPut Test - 03. Now there was no combobox to select Fuel Pump Relay so I had to cycle through the other components first. It showed the Fuel Pump Relay being switched On/Off but we couldn't hear the pump running. I checked the wiring diagram to find any fuses or relay. The relay is in the engine fuse/relay box after removing the screws we found it.

We removed the main fuel feed pipe to the filter and put it in a container. I went back to VCDS but it had cycled through to the next test. I came back out and tried it again and it came up with an error with something like system not enabled. I shut down VCDS and tried it again but it showed the same message. I switched the ignition off an tried it again and it operated the relay you could feel it clicking. So his problem is either its a coincidence that the fuel pump has stopped or he has a wiring fault or its something to do with P1063 error. I said he needs to check if the pump has a good power supply and earth.

So you can't run the fuel pump on a 2005 Q7 3.0 TDI without VAG-COM\VCDS unless you want to provide the pump with another power supply. I've Googled this error code and one user said he cured his by replacing the fuel filter but that would fix why the fuel pump doesn't run.

Oh there is a new update out VCDS 11.11.4

 

Remove the main feed to fuel filter place in container. Remove fuel pump relay fuse & get a wire from the positive of battery or engine bay post to the fuse post if pump is working u will see it drain the fuel. Some pumps are really quiet especially when the tank is full.

 

Problem solved. Both tank pumps shot probably due to removing contaminated fuel via filter housing.

 

Weird both pumps the main one & secondary one at once never heard that one before that's going to be costly.

Hi,

I'm in the Romsey area and have a USB VCDS HEX-CAN beta 12.10 and 11.11.5 I have performed a few mods and also coded a replacement key.

 

I'm in the Romsey area and have a USB VCDS HEX-CAN beta 12.10 and 11.11.

I don't think you've add the points? You can download the current versions 11.11.5.1 as well as Beta 12.10.5. You can set VCDS to notify you when newer versions are available.

How have you coded a replacement key without the SKC?

 

I thouight you must have used something else. Its a pity VCDS won't find the SKC if it did you could double the price and it would still be worth it.

 

I have a genuine VCDS USB-HEX-CAN running 11.11.5 software although am a novice yet but can scan and delete fault codes.
