Berlingo 1.6HDI EDC16C34 please help to enable EGR

[matej555]

Hello,

I would like to enable the EGR. I tried to do it myself (see the EGR ON file), but the car does not idle well. I only modified the two hysterisis maps. What did I miss?

Thanks

if your problem is to have original egr is not easier to write the original file?

This car was bought with Stage 1 tune and egr OFF. I don't have the original file.

egr is bad probably, also restore dtcs to original and see if egr error pops up

EGR was replaced with a brand new one. That's why I want to enable it now.

write this and see what error pops up, my bet's on egr

Thank you, will do it in a few days and report back.

I wrote the file, idle now works normally. There are two DTC-s P1459 and P0490. EGR valve is new. Any ideas? Thanks again for the file.

not the first time i see EGR replaced and still error, use better brand EGR (original part if possible) and double check wiring between egr plug and ecu with continuity and multimeter
