Hi guys , I had ago at chipping my ecu , I had a pc repairers fit my EPROM socket and I fitted the chip and now my car won't run
No fuel and no spark.
Issue lies with my EPROM I think as 3 pins won't take solder
So I've got fault code 00546 data wiring fault
So I think I would be better with a new ecu
As I've lost all faith in these home DIY chipping
I have a second hand ecu with matching pt number as mine
I have full vag com
Anyone know how to swap ecu's on immobiliser 1
I've read this
This procedure details how to swap engine control modules on VW/Audi/Seat/Skoda vehicles with Immobilizer I.

Switch OFF the ignition and after 5 seconds switch it ON again.
Make sure NOT to start the car within the next 2 minutes. After that, try starting the engine.
Seems easy and where do I find the spoken off PIN number ?

Haven't updated this yet. ,
I swapped my faulty ecu with a known working second hand one from the same engine code ect with same ecu number used the steps above and it works fine
