by **sinan33** » Fri Sep 05, 2014 5:17 pm

Hi!
I would like to make egr off on a VW Amarok 180 hp BiTdi car.
But, i can't find any switch or hysteresis maps related to EGR.
Would anyone please help me about egr off on this file?
Regards...

Look at
2D64E8 17x1
2D652C 16x1
2D65B6 17x1
2D65FA 16x1

i think this are hysterese maps
Try it an post result

Thank you, but are you sure that they are egr related maps?

For EDC17CP14 it works, change this maps to zero and try it. You will see it with VCDS if it work.
I have changed this on my A4 CAGA and i drive since 9 months

Thank you!
I will give it a try.
One of my friend has swiftec and he said that swiftec uses 2 of this 4 maps for egr off.

closing egr only with hysteresis maps,
wont help if electromagnetic valve on
egr dies and makes circuit error.

even if now all is ok,
in future when it does die, you will have dtc and limp.

Thank you my friend, it works.
But how can i find those hysteresis maps on other edc17 ecus easily?
Is there a quick way to find them like dpf switch finding?
