I have an Audi A3 1.9 tdi sport 2004 and would like someone to shed some light on fault 17903.
I have today changed the egr cooler, egr cooler control value and solenoid, as codes showed faults will all three, I deleted all faults and all cleared apart from this one 17903. I was on the understanding that this is the cooler control value??
All fuses have been checked too.
any advice would be greatly appreciated as I just want to get the engine management light off!!
Many thanks in advance
