I didn't think 1.8T's had an EGT probe.
They do if someone adds one for an EGT gauge.

The thing shown in the left of the photo is the #1 oxygen sensor. That's the one the ECM uses to determine if fueling is rich or lean so it can make adjustments in an attempt to keep fueling optimal. Further down the exhaust (after the CAT) is the #2 oxygen sensor. The data from this second sensor is compared to the #1 sensor to determine if the CAT is doing its job properly.

Kool guys thanks for tha info yeah car came with.

so this is tha wire that goes up to tha temp gauge it got melted to tha cat and now tha gauge doesn't work just blinks and doesnt even read exhaust temp. Do yu guys think this is tha reason why.. I put a short video of what tha gauge does.. thank

You don't think that I'll ruin it by splicing it?
Looks like it's already ruined. ;)

If you're lucky, the melted connector is the only problem and replacing it with a splice will get things working again. :)

If you're unlucky, when it melted to the CAT it also shorted a conductor to ground and blew the gauge. :(

Try contacting the gauge manufacturer to see if they have tech support available or if they can send you a copy of the install manual.

For all we know, blinking is the gauges way of signaling a trouble code. We don't know for sure because we don't have the manual for the gauge system.

Fix the melted connection and see if it goes back to working. Note the polarity of the wires so you don't hook them up backwards.

Before you chuck it in the trash and buy all new, contact the manufacturer and see what they have to say. You might save a few bucks that way.
