Multiple Engine codes HELP!!!
Hey volvo family new to this site and was hoping to get a little help on my 2.9 turbo turd. I have (CEL) codes out the ying yang and need help solving them.
1st code:P0351
2nd code:P0353
3rd code:P0356
4th code:P0352
5th code:P0420
6th code:P0234
now I know the first 4 codes are miss fire codes but I just put new NGK platinums in and still no fix. Is it likely to lose four cool packs at once? And I assume the P0420 is for the catalytic converter? And not sure what the over boost is about as well? Any help would be great😞

You may have a vacuum leak going to the "wastgate" and it's not dumping some of boost.
Here's a video of how to troubleshoot..

First thing - don't panic. Trust these guys in the forum, they know what they are doing.
Things to Check:
Vacuum Lines (google how to find vacuum leaks) - it's likely that this is the culprit of MOST of the problems you are having (if not all). I would check/replace the PCV lines, unless you've done so recently thats worth doing - even if it isn't the "problem" here.
Get an OBDII reader - they are cheap, and will give you more information. I like the BlueTooth type, so it pairs with the phone and you can actually see a little more information. OR get a Vida/Dice setup(or whatever the current/corrent version is called now) that will give you A LOT of data to look at.
I just had a similar problem with my XC90 - T6 (P0420 code) you can see the progress here 2004 xc90 t6 - p0420 (don't know if posting ext. links is acceptable on this forum... but it's worth a shot)
