P0128 code
I have a c32 amg with some upgrades and a lower thermostat I think it's 170 PTE. I went to go visit the grandparents in orlando for tday and the temps where cold as they hit in the 40s. On my way back i got a p0128 ECU unknown code on the drive back. Should I worry about the coolant temps being low. I reside in ft. Lauderdale so it's not usually an issue. Car felt great even after code but i didn't give it much gas. Cleared the code and will see if it pops up again. You guys think it's an issue? Thanks in advance.

I've been driving with PTE TS for years. I get P0128 on occasion, clear it with my dashdaq and continue on my way. No issues. Let us know if it happens again and note the outside temps.
