Have tried in the re-mapping forum but not had a reply so trying I get a wider audience'a attention
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 as 3 pins won't take solder because some mother board came away with the old chip
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 and I'm having it done by a professional mapping company now who will do it on dyno and suit it to my car instea of a generic map
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 system I think it is being 1996
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.
Can someone confirm the process please as seems too easy and where do I find the spoken off PIN number ?
