Exhaust Gas Temperature Sensor P2084

[bagnallman]

Wonder if anyone can help me?
 
I have a 2013 Astra GTC with an ongoing problem where the car will drop to limp mode.
With a code reader it has shown that the problem is “P2084 - exhaust gas temperature sensor, circuit range/performance bank 1 Sensor 2”

I erase the codes, but they do not disappear from the unit completely (they still remain on the list, but cannot be read once erased) and the car will be fine for a few months before the car goes in to limp mode and I have to erase the codes again.

Last year I had a visit to Vauxhall who confirmed this was a known fault and updated the software. However, it failed to solve the problem – it just now happens less frequently.

I’ve ordered the sensor off ebay with part number (55566195) – does anyone know if this is the correct sensor?

Also, is it possible to erase the codes completely from the ECU, could that be a cause? Or will they disappear once the new sensor is fitted.

I’m trying to avoid a visit to Vauxhall as they will refuse to touch the car without a diagnostic.

Thank you in advance for any time/help.
 
All the best
