Hello, I have used OBDEleven on my Scala and I have found this fault which regularly come back if I reset it. Does someone know with it ? I have made full check at dealer for 90000km operations about 6 months ago. Engine is 1.5 TSI 150.

There is a workshop manual for this engine somewhere on this site. I am pretty sure the valve is part of the EGR system.

That said if this is not putting on the check engine light then it's probably nothing to worry about.

Your car will store lots of transient codes in it's fault memory.

I just saw fault with OBD Eleven when I tried to solve a MIB problem. There is no warn about it on dashboard, so I will search if there is a simple way to fix it, otherwise I will do nothing.

I have another strange fault in OBD that don't give faults on dashboard, about Sunroof which indicates "Roof blind - No basic setting". My roof has no system for opening, just an electric blind

This is the problem with OBD11.

There are three sorts of faults:

Those which the car's brain thinks are serious, these will put the check engine light on.

Those which are transient, the ECU will ignore unless they become persistent or happen too often.

Those which report a condition that might or might not be relevant. The roof blind, as an example, could just be that the stop position has been forgotten. Or it could be that you have not specified a default position if you have that option (bit like you can have a memory seating position).

The faults to worry about are those which bring on the check engine light or those where the car put a warning message on the dashboard or those which light up some other warning light.
