Doblo 263 egr problem

Hello from Spain, hope you and yours are healthy!!!
I have a doblo cargo combi 263 1.6 105cv 2012
After 200.000km dashboard show me check engine light. I unmounted egr and butterfly to clean them. I deleted check engine light with alfa obd2 Bluetooth.
After some months again check engine light and alfa obd show me following errors P0490 P0487. I think then, it could be an eléctric problem on the egr. I think would be better to mount a new egr. Whats is your opinion or experencie.
On the other hand as blue & me unit got dead I mounted a tablet on the dashboard.

Re: Doblo 263 egr problem

Those codes do seem to point to a failed EGR or a wiring fault to the EGR.

One code is complaining it cannot detect a difference in resistance from the valve when it thinks the EGR's valve position should change.

The other is complaining it's cannot detect a difference in manifold inlet pressure when the valve should be open or closed.

So you'd presume the EGR is either not working or cannot work due to a wiring fault.


There is some more infomation on the Blue & Me unit on some of the other model forums.
They can fail and cause the battery to drain. it's worth searching in the 500 section.

Re: Doblo 263 egr problem

After replacing the egr by a new one I got the same problems, p0487 and p0490. I deleted them with alfaobd, but they appear again and later the advice light on the dashboard. So, I don't know what to do know.
If you have any idea it would be very welcome.
