Hello, guys, I have a friend which has an Audi A3 1.8T from 2000, and he bought it with a cluster problem ...

When I turn the ignition on, the cluster turn on and off, by itself and keep doing it.

When I try to start the car, it starts and turns off immediatly after (immo problem)

I wanted to defeat the immo using the vag tacho or vag commander, but there is a problem with the k-line (short to ground) and I can't use the OBD port.

So I thought I'd defeat the immo on the ECU directly !!!

The thing is the guide I found here is for a ME7.x ECUs, which I thought he had on his car, but when I took it out, I noticed that the pinout wasn't the same, and I started digging to discover that his ECU is ME3.8.3 06A 906 018 CK (0 261 206 515) from 03.08.99

http://nefariousmotorsports.com/forum/index.php?topic=5068.0title=

I found the pinout here : http://nefariousmotorsports.com/forum/index.php?topic%3D1191.0

But what I'd like to know guys is if I can use ArgDub's software with this ME 3.8.3 ???

How do I get to boot mode ?

Where is the ignition pin ?

Do I have to ground a pin to get it to boot mode ?

Has anyone done a immo off on this ECU ?

Can I defeat the immo with vagtacho or vagcommander having the ECU on the bench ? (I know it might be a stupid question because vagtacho communicates with clusters, but there never are stupid questions for someone who wants to learn right ?)

Thank you for your help !!!

That ecu has to be desoldered, read, then programmed in a chipreader, and resoldered.

Ok, so there is no other way ?

You can read this ECU via obd, but the maps part right ? Not the immo ?

That ecu cannot be read via OBD, Just written with MPPS when the programming pin (43) is powered!

All right, thank you for the info.

What can you wirte with mpps ? Immo or maps ?

If maps only can be written with mpps, could you advise me on some programmers ? I've heard about willem programmers, what do you think about these ?

Thank you.

That is a good programmer.
I have one and know many others that have one.
Does a good job and is very reasonably priced.

The dump in the serial eeprom (24C02) of that ECU can be obtained using Monoscan (available in this forums: http://nefariousmotorsports.com/forum/index.php?topic=4420.0 ) and a dumb KKL interface. To write it, some M383 Motronic boards can be read/write in circuit others not. First you can try read the 24C02 using an 8 pin clip and an programmer, with ECU powered and main XTAL shorted to avoid processor startup. If not the only option is to desolder it.

To immo off you can find the info here in forums, but I have done some guide from the info collected here. Check it: http://www.mediafire.com/download/azvde84uivxpx05/M383_&_M592_Immo_OFF.doc. Also you try this file ( http://www.mediafire.com/download/geiy3bl3eyux8o2/Skoda_Audi_VW_M383_IMMO_OFF.bin ) with immo off and DTCs cleared. Just burn the 24C02 with it, install in ECU and test in car.

Hope it help you.

 

Hello guys, I'm new to universal programmers. I need to buy along those the adapters for the different eeproms I might use right ?

eliotroyano, you got me confused. The KKL cable allows me to read it directly right (if the board supports it of course) with the monoscan software ?
If not, I could try with the 8 pin clip with the clip software.
And finally, I could also desolder it right ?

If I try with the KKL cable, (there is no boot mode for this ECU right ?), I should only plug it using +12V, ground and k-line right ?

Thank you for the help guys !!!

Monoscan MAY read it, but to write it you must desolder anyway, so I don't waste the time.

As for programmer, I have a GQ4-X with a pomona test clip. I also have a SOIC-8 ZIF socket, but I rarely use it.

Hello and thank you for your answer.

What is the difference between the gq4-x and the willem ? It's double the price ...

What are the thing I should consider when bying a programmer ?

Thanks.

Monoscan is an option to READ ONLY the eeprom dump without open ECU but it doesn´t allow you to write it. You can read as select Read Eeprom, Start Address 0x0000, Size 256 and Save as. That's it.

The comment about the 8pin clip is that during my tests some boards accepts to be read and/or write using it, but it just a matter of luck, some ones can do it others not. I do not why.

But I agree with DDillinger as you need to write a new dump in 24C02, just desolder, read, modify, write and solder it again, without other procedures. It is the most secure way.


These ECUs doesn't have a boot mode just as ME7 ones. Applying +12V to ECU pin 43 allow an MPPS programmer to write the whole flash eeprom content. But it doesn't read the serial or flash eeprom just write the 29F200 inside it. That's all.

I agree.

Both can do the job but if you plan to use it more in future, GQ-4X is a better option. If not, and you will use it just to do a job, a small, 8pin, 24Cxx, usb programmer can do it too, I think.

Thanks for the input !!!

I plan on using it with other chips too, but the problem is that the GQ-4X is quite expensive ...

Looking at the board, I can see that the chip has already been desoldered ...

Is it possible to put an immo offed file from another ecu and write it in ?

Thank you.

The cleanest option is adapt the ECU to cluster. But as you have some K-Line issues, next step is to immo off ECU. Personally I will try to correct K-Line issues it could left you some other troubles in the future, including diagnostic problems.

Ok generally what I have see is that all this M383 ECUs are Immo II and are connected to Immo II or Immo III clusters. From you comments you could have Immo III cluster, then with just with tacho pin and adaptation should solve the problem (all this is ok if you don't communication issues). Remember that cluster should talk to ECU (K-Line from ecu to W-Line in cluster  and then K-Line from cluster go to diagnostic OBD2 port; well at least here is how is connected in my car) that could be generating you communication issues, including immo behaviour you are talking.

About the ECU dump the best option is to immo off the current 018CK serial eeprom dump. Remember that serial dump should match flash in you ECU.

I agree with you, the k-line has to be fixed. But my friend is wondering if he sells the car for parts or if he tries to fix it. But if the doesn't start, he won't want to fix it ...

If it was my car, I would have tried to find the k-line problem for sure ...

The problem with adapting the ecu to the car, is that I have to get the SKC in order to do so ... Since the cluster seems to have problems too, I don't think I can ...

We'll see how it goes ...

Hello, I'm back with some news ...

I took out the radio, and the k-line came back but I still couldn't diagnose the ECU ...

My friend has another audi A3 TDI PD100, and we took the tdi cluster to put it in the 1.8T. It worked like a charm. I was able to diagnose the ECU, cluster immo ...

I wanted to adapt the ECU to the TDI cluster (I used vag commander to get the PIN from this one), but I can't since I don't have the SKC from the 1.8T ECU nor from the cluster ...

When I put back the original cluster, it goes crazy, it seems I can diagnose it sometimes, but the connection fails immediately ...

The only option left is to immo off the ECU right ? Or do you see something else ?

Thank you guys !!!

It's me again !!!

I know I have a lot of questions ...

If we wanted to swap the ECU, could you tell me if there are others that are compatible (plug and play) ? It's a real pain to find the exact one, since there are so many versions ...

Thank you ;)

Friend you have many troubles. My advice is try to test ECU and Cluster on bench to isolate the problem. You need to know if you have really a wiring trouble or any module (ECU, Cluster, ABS, CCM, etc....) is going bad.

To clone you ecu you need to copy flash & serial eeprom dumps to a new one. Basically any M383 or M592 1.8T ECU can do the trick.
If you want to be more specific to car use any of these:

Hello guys.

I finally received my programmer ... I desoldered the chip and read it.

Here is the dump.

Do you think I could flash it the version eliotroyano gave me ?

http://www.mediafire.com/download/geiy3bl3eyux8o2/Skoda_Audi_VW_M383_IMMO_OFF.bin

I'm asking because it doesn't seem to be the same ...

Thank you guys ;)

Here is my attempt to immof.

Could someone check please ?

Thank you guys ;)

PS : how do you clear the dtc ?

PS 2 : where can I find the SKC in the immo dump ?

I have tested that generic file with some sucess. Any other case you can test your ori 06A906018CK immo off version.

In the past I know how to do it, but I don't remember. I need to check my notes. I remember something like force "FF" somewhere in the last line of the dump.

Hello and thanks for the quick answer !!!

I trust you when you say your file is ok, but I'm just asking about compatibility with mine ... Since the ecu doesn't have the same part number and the dupm seems different ... I know I'm lazy, but I don't want to try anything that won't work because I'll have to solder take back to the car (15 minutes ride), test, if it doesn't work, back home, desolder, reflash, resolder ...

I'll trust your file more than mine, you said it works. Because the chip has already been desoldered and replaced on the ecu, so I'm not sure about the integrity of the file ... But my concern is more, is ir compatible with my ecu ?

What about the skc ? Do you know where to find it ?

The immo off on my car is done properly ? Checksum too ? Because on the word file it said no checksum, if I find A0 at 0x6 or 0x7, but in the pictures it was different ...

Thanks ;)

Friend I understand your concern. Your 06A906018CK Immo OFF file and mine are equal, it will work. The generic one is some kind of virgin one in case that you don't have the dump. Just use the Immo OFF file you will be OK.
About the SKC I think that most of the M383 & M592 ECUs are Immo II, so no PIN Code is needed for new ECU adaptation. You can follow Ross-Tech Immo II ECU swap procedure --> http://www.ross-tech.com/vag-com/cars/immobilizer2.html.
In my case ECU (M383) is Immo II and cluster is Immo III.

Ok, thank you. I'll try and report ...

Hello guys !!!

I tried mine today and it worked !!!

As for the SKC, I don't need it to adapt anything, I just wanted to know where to find for educational purposes ...

THANK YOU !!!
