Title: Fuel Pump Relay gone?
Post by: Gabriel2202 on 20 October 2011, 16:07

I have had these fault codes on vagcom and when i delete them they show up again straight away before ive run the engine again!! :huh:

as they're all short to ground does this indicate an electrical fault? possibly fuel pump relay? as the choke is always on when first starting up even on the hottest days.... and sits at 1200rpm for a few minutes...

here are the codes i get:

17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)
            P1297 - 35-00 - -
17633 - Fuel Injector for Cylinder 1 (N30): Short to Ground
            P1225 - 35-10 - - - Intermittent
17635 - Fuel Injector for Cylinder 3 (N32): Short to Ground
            P1227 - 35-10 - - - Intermittent
17636 - Fuel Injector for Cylinder 4 (N33): Short to Ground
            P1228 - 35-10 - - - Intermittent
17634 - Fuel Injector for Cylinder 2 (N31): Short to Ground
            P1226 - 35-10 - - - Intermittent
17833 - EVAP Purge Valve (N80): Short to Ground
            P1425 - 35-10 - - - Intermittent
17955 - Boost Pressure Regulation Valve (N75): Short to Ground
            P1547 - 35-10 - - - Intermittent
17525 - Oxygen (Lambda) Sensor Heating Circuit: B1 S2: Short to Ground
            P1117 - 35-10 - - - Intermittent
17843 - Secondary Air Pump Relay (J299): Short to Ground
            P1435 - 35-10 - - - Intermittent
17938 - Camshshaft Timing Adjustment: Short to Ground
            P1530 - 35-10 - - - Intermittent
17829 - Secondary Air Injection Solenoid Valve (N112): Short to Ground
            P1421 - 35-10 - - - Intermittent
17697 - Boost Pressure Control Valve (N249): Short to Ground
            P1289 - 35-10 - - - Intermittent

>as they're all short to ground does this indicate an electrical fault?
I would say so.

What car is it?

Are all these components on the same loom?  Possible multiple looms are damaged of course.

Looks like a grounding issue to me!

Check the leads from the negative battery (even the one under the battery) and to the engine.

Worst comes to worst, get a nice 4awg wire and create a new ground and see what that does.
