Fuels Temperature sensor

[Rusty2009]

To bring some more information into this thread (As the wife's Mokka is having the same issue). I stumbled across this TSB on the Mokka forum which may also help.

TSB 3134
Problem Description
SVS lights up along with DTC P2080 and/ or P2084 exhaust gas temperature sensor 1 and/ or 2 -
performance malfunction,and/ or P0181 fuel temperature sensor performance,
emergency mode activated and rough engine run.
Cause
Investigation revealed bad contact of connector B131B "exhaust temperature sensor 2".
Also possible that bad contact is given on temperature sensor 1.
In some specific cases DTC P0181 (same 5- volt reference circuit) is set alone as a consequential DTC of
P2080 or P2084 which did not reach the range to get set itself.
Resolution
If suspicion of bad contact is given please repair as required,
otherwise replace connector of exhaust gas temperature sensor 1 or 2.
Also check the engine datalist for any malfunction/ deviation of the values while engine is in warm up phase or after a
soak- time (over night- time) of 8 hours.
If an implausible deviation of the temperature sensor has been found please replace the relevant sensor
with part- No.: 13384371/ cat.- No.: 12 87 312.
