Fault code 17903 - Switch-Over Valve for EGR Cooler (N345): Open or Short to Ground

[Michael Blythe]

All,
Wonder if anyone can help shed some light on my fault with my A3 2004 2.0 (2004) tdi. I've had the car 6 months and touch wood its been issue free, now done 96k miles.

A engine warning light appeared last week, albeit I've not suffered any power loss, mpg reduction or abnormal temperatures. I connected the diagnostic tool and it reported one fault, 17903. I've not had much success finding what the fault is other than a German blog which discussed it was :-

17903 - Switch-Over Valve for EGR Cooler (N345): Open or Short to Ground

It also mentioned replacing the glow plugs and fuse number 34 although I believe it was specifically for a Passatt (unsure of year)

Any help would be greatly appreciated as I'm stuck where to go.

Hope all had a great Xmas and new year.

Cheers,

Mike

What did you use to code read that and is your engine type code BKD?

[Michael Blythe]

Hi Crasher,
Thanks for the quick reply. I used a U281 OBD-2 CAN-BUS CODE SCANNER for VW/AUDI/SEAT/SKODA CAR - only just bought it when the fault appeared. It showed up 17902 only.

I believe the engine type is BKD, it's a 2.0 tdi 140BHP and the cars on an '04' plate.

I can't see 17902 or 17903 on my listing I have here at home.

Sorry typo, the fault code is just 17903. Given the code is not appearing on your listing is this something to be worried about?

Anyone think a phone call to Audi dealership would help?

I can't find it, my GFF Light is refusing to work.
