MIL is on, scanned the car (98) and found these codes:

modulating piston displacement sensor g149

fuel temp sensor open circuit g81

glow plug monitoring (sporadic)

any ideas what could cause this?

the car starts instantly, runs strong and does not smoke:confused:

admin delete, it was relay 109
