Title: ECU Swap A3 1.8T AUM HJ TO HN
Post by: Andrej1701 on March 13, 2021, 12:02:38 PM
After i bricked my ecu and dont have the equipment to boot it, i ordered an ecu from an other 1.8t aum engine with 210 ps tuned by an popular company.

My ecu has the serial number : 06A 906 032 HJ

The ecu i ordered has the serial number : 06A 906 032 HN

The clue is that the ecu i ordered has got the immobolizer deactivated and thats why i think its plug and play and get the car started.

Also i readed in the fr that HJ and HN are near to similar.

Am i right or what do i need to code ?

LG

hardware wise they are the same. one is 150 factory tune and the other is 180. hardware wise all a chassis wideband 1.8t cars have the same ecu hardware only differences are calibration. so if the ecu runs your car without issue youre fine

I plugged it into my car but the car is just cranking and wont start

In VCDS the code is : 01177

Does someone have experience or can help?

Should probably adapt the immobilizer with VCDS procedure if you haven't. I recommend you to get the hardware to fix your original ECU as it seems this is getting way to complex for no reason. Fix it in bootmode, do it properly.

Yes i will buy the right equipment for that.

The code is 01177 64-10

I readed that it may be the KI . I bought the ecu from an golf mk4 1.8T AUQ

my assumption is the ecu isnt immo offed

Yes looks like the immo of the ecu isnt offed right ..

I will send it back and ordered an ecu that runs fine

Your assumption was correct immo off had bad checksum...cant trust certain people

Now i ordered an other ecu with immo off but my vcds isnt going into the channel 1 engine.

It has the same issue as before : 01177 64-10

Why is it not going in the channel 1 ? What should i do?

If you cant connect to the ecu its bricked.

Okay sorry my bad  ;D
A pin wasnt straight and thats why it didnt communicate with the engine ecu.

But my ecu shows the Extra Number : XXXXXXXXXXXXXX XXXXXXXXXX

Is that how it should be with immo off or is there something wrong?

No data or xxxxxxx in extra shows it’s immo off
