Before you do anything else find a working ecu thats been tested get both SKC login codes from that ecu and your cluster and pair them together the correct way forget the immo off and code them together properly using VCDS

So I wrote the original eeprom bin back (from when I got the ecu), can't pair together with VCDS, when entering old/cluster PIN in adaptation 50 it says System not OK. I login succesfully and Im sure the SKC is correct, because when entering a wrong one nothing happens. It would be really hard to find a working ECU that I can put in my car, none of my friends have audis/vags. The only way for me to get a working ecu is to buy one. And well, I did buy one that the seller said was working.

Just doing the immo off on the eeprom still gives me immo DTC's on the cluster. Am I missing something or what? Read the stock eeprom > immo off > write it back and thats the whole process.

Man all this because I wanted bigger injectors. Does anyone have any more ideas? Its the 518AL, I can't flash anything or read the flash because it doesnt let me with the immo not working. The new ecu is in a plastic box instead of a metal one. Maybe I should try a different eeprom dump on it or something? The one BlackT sent earlier?

Cluster will always throw a fit because the ECU is not paired to it.
If you just immo off the eeprom and leave everything else like it was, then car should start.

Do exactly that instead of changing a million things at once.

Once the car starts and that is verified with an immo-d off bin, then re-enabling and pairing immo is the next thing, but you might have to change sw version.

It doesnt start with just immo off. Sad If you say it should then Ill go back to checking mechanical problems. Maybe my new walbro 255 fuel pump somehow died (I drive on LPG). Wouldnt be surprised with my luck

I am not home right now, but I found theese images on the internet to show examples. The Metal one has some sort of glue to keep a seal so that water doesn't get in and has this plastic black plug. The plastic one has no sealant and plug.

As long as I know Audi A4 B6 1.8T has never come with sealed ECU(first pic)

3.0 with M7.1.1 have sealed ECU, but 1.8T not

Please take a pics of your ECUs not from internet

Managed to get rid of the immo dtc by connecting my old ecu and flashing the stock eeprom, then when connected the new ecu with immo off, there was no dtc. Trying to read flash with nefmoto gives me

Quote
Negotiating communication timings.
Successfully changed to new communication timings.
Requesting security access.
Security access granted.
Validating flash memory starts at 0x00800000 and ends at 0x00900000.
Validation failed, ECU reports that security access is not granted.
Memory layout validation failed.
Disconnecting because no response was received for the Tester Present message.
Disconnected.

Fuel, spark, timing, crankshaft sensor, camshaft sensor, relays are all good, even tried to check if somehow my LPG ecu was messing with startup but no dtc's there. I don't think there is anything else to try or do. Any suggestions are welcome of course, but I don't know what hasn't been tried yet. I kinda need the car and im not gonna have time to fix it starting monday, so I'm thinking of finding some tuner or mechanic or idk what to try and fix it.

Compression test has been done around 10kkms ago and showed 13 on all cylinders (12.9-13.1 I don't remember exactly). It was this along with testing the oil pressure(also very good results) that lead me to believe this engine (and car) was worth investing time and money in.

IT STARTED UP
Upon realizing that I would have to travel using public transportation I found the issue pretty fast. Just look at the picture attached. The hose attached to the fuel pump broke even though it was brand new and part of the walbro 255kit Cheesy It was all terrible timing as it happened right after changing KRKTE. THANK YOU EVERYONE VERY VERY MUCH Sorry you all had to put up with this!

Btw someone sandblasted that ECU case, it's not supposed to be like that.
Also your new ECU is 40mhz, old one was 32mhz.

But yeah if it didn't start with immo off file it was clear that there's problems with the car from the start.

I guess in that case I should try to get the new ECU working. Faster == Better  Grin Thank you for that!
