Hi,
I need help with a fault code on my 2017 Volvo XC90 T8.
Code: IGM-P0A9249 – Hybrid Generator Performance (internal electronic failure)
The code will not clear and comes back immediately.
Has anyone seen this before or knows what could cause it?

Thanks.

hello,

volvo xc90 t8 2017

Fault code: CCM B15B693 (Combustion Preheater Module – no operation)

Fix: I replaced the combustion chamber (burner) inside the heater (CPM).

After that, the heater works нормально and the error is gone.

So the problem was inside the heater, not wiring.

Hope this helps.
