Hello everyone!!!
I have a problem with egr SID 803a from Citroen Jumpy.
I have done this for SID 803a of Peugeot 407 without problems, and I am trying to adapt a solution to this switchboard.

1-I used PPD Maps to find the DTC switches.
The error stored with Lexia is P1471.
I do not know if these DTCs are well annulled.

2-I tried to attach the SID 803a Peugeot 407 maps.
I found this:
6A330 16x1: GES_ACT: fuel mass threshold for EGR disable.
Set this map to 0.
6A370 16x1: GES_ACT: fuel mass threshold for EGR enable.
Put 65535 on this map.

Are these maps correct or are they the reverse ???

3-It is possible that maf air maps for egr are:
72322 16x16
72522 16x16
72722 16x16 ???

Put the maximum value ??? Or leave standard ???

4-It is possible that c_tco_egr_max be address 6B642 in 8 bit mode and offset -50?
And c_tco_egr_min be address 6B643 same view 8 bit value -50 ???
The values ​​for this are respectively 105 and 10 ºC.

5-c_amp_egr_min is it possible that it is address 7AC26 and it is worth 900 hPa with factor 0.082918 ???
Put at maximum value ???

Can someone solve this EGR without DTC P1417 ???

I have attached what I have done, yesterday I tried something else and the vehicle already has MIL and from 2500 rpm sticks jerks.
The EGR is broken, air value at idle is 136 mg / stk.
I will post both files.
ORI and my work.

Thank you.

Regards!!!

You heve to block the EGR pipe and remove the DTCs with switches.
That's all.
