Autotuner Cannot Write Audi A8 EDC17CP44 via OBD Solution

Problem:

It’s an Audi A8 4.2 TDI 2014 with Bosch EDC17CP44 ECU. Tried writing 3 times with Autotuner via OBD but had same error every time. This vehicle has two ECU’s.

First said “Could not start transfer: 34 22”. Eventually said “This is neither a valid tuning nor a recovery file for the selected ECU”.

How to fix it?

Solution:

This ECU software ID is 0008.

0008 got new bootloader, there is a bug patching it in obd write, other tools too!

0008 software has a patch that blocks writing/flashing via OBD.

You can use bench, do manual bootloader patch. Bench this ecu, I’ve had this issue with kess3 everytime, on the 3.0 tdi, its the same ECU EDC17CP44.

Optionally, you can downgrade the software to 0005/0003 via OBD, and then everything works over OBD as well.

Xhorse MVCI Pro+ vs Openport 2.0 for Techstream

The following is feedback from real users regarding the use of Xhorse MVCI Pro+, Openport 2.0, and Toyota Techstream software. Hope it helps who choose a proper Toyota J2534 cable.

 

Xhorse MVCI Pro+ vs Openport 2.0 for Techstream:

“The MVCI+ Pro (new black J2534 cable) is truly compatible with all protocols. The original Tactrix OpenPort 2.0 had its limitations.

The photos show the differences compared to an OpenPort 2.0.

Based on my experience using this new Xhorse cable, I can say that it works much better than an OpenPort 2.0.

It works perfectly.  No bugs so far.

On Techstream with an official OpenPort 2.0 cable, there were many bugs and a slow connection to the vehicle.

With Xhorse, there are no problems.

Mazda ids work very well and diagbox PSA very well.
Future testing Renault canclip.”

 

How to Tell if Benz Key is FBS3 or FBS4 by Key?

Here is the tip to identify if your Mercedes Benz BGA key is FBS3 or FBS4 by key shell and key circuit board.

 

1.By Key Shell

We can tell FBS3 or FBS4 from the key shell.

We can also determine whether it is an FBS3 or FBS4 key from this part of the key. Here is a string of numbers.

With a letter “K” means it’s a smart key, without “K” means semi-smart key.

 

3 numbers before this space indicate it’s an FBS3.5 semi-smart key.

4 numbers before this space indicate an FBS4 semi-smart key.

“K” at the beginning means it’s an FBS3 full keyless smart key.

“K” in the middle means FBS4 full keyless smart key.

 

2.By Key PCB

On the FBS4 key board, there is a transistor on the right side here; the FBS3 does not have one.
The chips on the FBS4 key board are smaller than those on the FBS3 key.

How to tell if it’s smart or semi-smart:
A full smart key will have an extra accelerometer chip on the top right side; a semi-smart key does not.
