Bigjobbo 0 Posted October 13, 2009 Report Share Posted October 13, 2009 Hi mate, yes i did and the OS we use doesn't seem to have any wiring diagrams for engine ECU etc. I'm afraid a bentley manal may be the only place to find it. I'm trying to get hold of one myself. Will try again thursday though, i may have missed it. Link to post Share on other sites
Bigjobbo 0 Posted October 15, 2009 Report Share Posted October 15, 2009 Hi mate, just to confirm, connector T4a, the yellow wire pin 3, connects to the ecu, as does the white wire pin 4. The other two, which are marked as Brown, and red/white are for the heater within the oxygen sensor. Link to post Share on other sites

Bigjobbo 0 Posted October 15, 2009 Report Share Posted October 15, 2009 You can get repair kits off vw for individual connectors, you get the pins and a length of wire specific to what you need, your lambda probe VAG reference is G39 and connector is T4a if your ordering bits.
