now ask your question

the super early 05 has a different engine, the compression ratio, shape of the combustion chambers, and other small changes like hpfp pressure sensor is not the same setup. Was the key not paired with the cluster? Because the immo off ecu should work and not cause any issues unless the the key is not right for the car. Also, if you can provide the eeprom dump from the original ecu. the skc can be extracted and at that point you should be able to use vcds to login and adapt the key. youll need to have the original ecu in the car to do this tho

Long story broken down some. Bought car non-running, PREVIOUS owner bricked the ECU trying to perform a Eurodyne tune. Which caused little to no communication to the ECU, fans come on after keys on, no check engine light up. He sent it somewhere (remain nameless for now) that charged $270 to fix the ECU... Ha.

1. I bought a used ECU, matching part number, installed communicates as it should. I should have just towed it a dealership and paid to have it adapted.
2. Tried buying a china Ktag to BDM either ECU with a new file, base file for the original ECU, couldn't get it to communicate. Tried same with replacement ECU.
3. Ended up buying an Autel IM508 to be able to pull PINs. Successfully, I thought to adapt the ECU to the cluster, VIN swapped to ECU and read but couldn't program keys. During this step somehow messed up the cluster, def error.
4. Bought a used cluster, attempted to adapt the cluster to the ECU, keep getting communication issues.
5. Sent out the ECU to get immo delete, came back, car starts, but hazards after start and no hvac, immo faults.

So that's where I'm at right now. Hoping that just swapping over a set of already matched parts will work but trying to make sure it won't cause other problems in the process... Ideally at some point I'd like to have my VIN loaded properly and the original mileage back in, but I'm not pushing my luck. I figure I at least have a fallback "running" setup in the meantime.
