How to swap an ecu
« on: 23 November 2013, 23:20 »
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.
