It did have at least half dozen error codes come up , but I’ve just I’ve just gone back out to it and reattached the ecu, bloody thing started straight away and ran fine I plugged in the diagnostic and it’s showing no codes present I don’t have a spare key for it

Hello, I have a 2006 Octavia , 1.9tdi L&K , car has been brilliant until now, I started getting the odd low oil pressure on the dash bleep now and again, then the odd morning where it would start then immediately stop and the immobiliser key sign on the dash. All electronic related. Now it just starts and immediately stops. I sent the clocks off to get them checked out, clocks come back but same problem is still happening. I have removed the ecu from the front scuttle for testing. No corrosion on the ecu pins at all All fuses are fine. Can anyone advise if I’m on correct procedure or have I missed something else? Cheers
