e-C4 2022 P0C46 error code

Unread post by JT99 »

2022 e-C4 MK2 (UK spec.)

I read the DTCs yesterday with Car Scanner, and I have
P0C46(25) [0x0C4625]
Hybrid battery pack coolant temperature sensor - circuit intermittent/erratic
Status: Test failed, Confirmed
This has come back since I last cleared them- (there were 77 last time after the 12V had gone flat! now I only have 39, including this one and P2299 for pressing both pedals at once)

Is P0C46 a phantom code (it doesn't have a hybrid battery pack!), or is it something I need to raise before the warranty expires?

I'm not overly bothered by the other 37 codes, they are mostly marked as inactive, (which I assume means historic and not a problem now) the car seems to work, and having watched a couple of documentaries about the RAF, it seems typhoons have much worse electrical problems and they cost £150 million each. (Also the solution is still remove the power and turn it back on......)

I would stop intervening yourself if you have warranty and get it to the dealer! You risk rejection of warranty if you attempt any repairs or change anything, so be aware.
