VAG EDC15P Not Accepting Remap File

by **dmcc16** » Wed May 04, 2016 1:01 am

Hi everyone,

Over the weekend I was working on a VW Passat PD130 AVF EDC15P ECU no. 038906019EP. I downloaded the original ECU map file using MPPS and created a remap file from it. After writing the file with no issues the ECU bricked and I had to recover it using my bench setup. After recovering the ECU and loading the map file I quickly tested it in the car which started no problem so I then removed it once more to reseal the ECU. After resealing it and putting it back in the car the engine would not start and the glow plug relay was continuously clicking while cranking the engine. I plugged in VCDS which could not communicate with the ECU and MPPS could neither read from nor write to the ECU. I again removed the ECU and recovered it on the bench reflashing the original file and the car ran perfectly again. I've triple checked the remap file, all maps are correct and the checksums are correct. The correct vehicle selection in the dropdown was double checked before reading and writing. Has anyone every experienced this before and is it likely a fault with the ECU itself? I've been using this software for over a year and remapped numerous VAG EDC15 and 16 ECUs using this software and never had this issue before.

Any insight into the problem I would greatly appreciate.

Many thanks,
Danny.

I did think this initially but I've had no issues with the software on any cars before or after this one.

MPPS V12, the remap was written by myself.

did you use vagsuite?
when i compare the original and tuned i see strange adress... could be protection.
and do you have a pre tuned ecu? like abt?

I have recalculated duration 0 and 1 tables for higher fuelling. Duration maps 0 and 1 are only used under full throttle which is where I want the extra fuelling. There is no need to recalculate the remaining duration maps as they are used under normal driving conditions. The remap was derived from the original ECU file which was never remapped before as far as I am aware. The file that I read of original was an original PD130 map file.

I used WinOLS.

you could try it with vagsuite ;)

if you need a good tune contact me by pm ;)
i have 2 tested files.

1: 160HP and 380NM
2: 185hp+ and 400NM+

Thanks for the offer, I've been tuning myself for nearly a year and a half and this is a customer's car so I wouldn't be using any tune that isn't my own. I was more interested in just finding out what the problem is. The first time round the software loaded on fine and the car started and ran perfectly. Then when I removed the ECU to reseal it and put it back in it bricked which I cannot understand how that happens. I might just start from scratch with a new file and go from there.
