2004 Volvo XC90 - P0234 Limp Mode
2004 Volvo XC90 T6 AWD
Hey guys, I'm new to this forum and would like some help.
my Volvo that hasn't been driven in a while, after jump starting it - it drove fine, until I gave 3/4 throttle. Then these codes happened.
P0234
P0352
P0351
P0353
P0354
P0355
P0356
I'm not sure why they all came on together when the car idles perfectly(aside from limp Mode - "Reduced Engine Performance"). Is this a known problem? Any help is appreciated.

P0351... P0356 are all related as ignition coil faults. Not likely all six coils would fail so it usually points to an electrical issue - I'd start with checking the battery voltage when driving to make sure the battery is good and that the alternator is charging. The P0234 is a turbo overboost fault code. Basic checks are to inspect all hoses attached to the turbo and the turbo control valve for blockages, damage etc. This can also be set off by the ECU detecting misfires.
