Hi all, 
The missus borrowed the ed30 yesterday and then messaged me say the engine warning light had come on. Typical! 
Anyway last night I did an error code reading and got these codes:
Fuel Level Sensor (g) 
Sporadic (002) - lower limit exceeded
Rear Heater Core Temp Sensor (g154) 
The car runs fine, just googling the codes seems to bring up coil packs but i changed them a couple of years back. Could it be that?
