You must do the mechanical part of EGR OFF also. By just turning DTC off is half the job... Your engine will never run good if You have a sticky or cracked or leaky or... valve. Just think how the EGR system works and will understand that the software part is not enough unless You are lucky... but I would not return the car to my customer hopping in luck... ;)

Hello,

Here Your file EGR OFF and Checksum OK.
Program file and then erase DTCs by diagnostics...
Try and report back please.

Hi,
Thanks for reporting back. I can not connect this DTC with the mods to Your file. Never heard of something like that before.

Best Regards

HI. I don't think so either. I think the file is good.there may be some other problem.
Can EEp be a problem?

I do not think so.
Try to disconnect the battery for 30 minutes and see if that makes a difference.

Hi,
Somebody can help to me?
I can't remove dtc's correctly, because engine light stay on, but with diagnostic no dtc!

Hi. IAW4MV.TV is a little different from the rest. It works without dtc, which is the case with other types of 4MV controllers, but there is a Check Lamp. Is this a tested solution for 4MV.TV? Can I have a password?

Hi
This was two years ago...
it is a CLOSED PROJECT
It was problem with OBD write, because not write full flash, just maps only!
So try to remove flash and write eep programmer on table!

Igazából KTAG-el olvasom, szétszedve, KESS nem vitte OBD-n szintén, de arra voltam kíváncsi hogy a 00FF megoldás helyett amit kaptál FFFF megoldást (Styber-től), az működött-e rendesen, dtc és Check lámpa nélkül.
Magyarországból írok , ahogyan te is :) Akarok csinálni egy módsoítást , mert a 00FF-el eltűnt a dtc viszont egy idő után visszajön a check lámpa (dtc nélkül). Jövőhéten lesz itthon testvérem, csak már biztos megoldást szeretnék felírni.

ENGLISH
Actually, I read it with KTAG, disassembled, KESS didn't take it on OBD either, but I was wondering if the FFFF solution you received (from Styber) instead of the 00FF solution worked properly, without dtc and Check light.
I'm writing from Hungary, just like you :) I want to make a modification, because with 00FF the dtc disappeared, but after a while the check light comes back (without dtc). My brother will be home next week, I just want to write a sure solution.
