I am looking at having to replace my g235 (audi part number 078919529k) sensor this is the sensor on the driver side( RHD cars)

the price the Audi dealer near me quoted is £260 inc vat.

has any one found a cheaper supplier with quick delivery time?

.... time goes by...

I ahve just taken the old one out took 15 mins max and it seems fine. the probe end it solid no crfacks or obviuos defects and the sender end looks good to.

it actually has part number ending D not K as above.

The code I was getting was EGT1 (G235) Open or Short to Plus

cant see any signs of a short circuit. could it be the wiring inside the unit is knackered? could it be the wiring that attached to the sender unit an into the ecu or wherever it goes?

On a seperate note I noticed my coolant ank cap was a bit loose so took it off and found not only the pressure cap inside was all broken but thjer is also a hole int he tank in the bottom of the filler neck.

Could this be why my coolant light has stayed on permanantly after replacing the Coolant temp sonsor?

cheers

Matt

am I feted to replace it and spend the money or is there any other solution. another sensor that is shorting it out?
