PPI shows P0305 misfire on CPO ('16 GTS) but dealer brushing it off
 

Hi - looking at picking up my first p-car and came across a CPO '16 GTS at my local dealer. Took it in for a PPI, which was largely fine, but the shop noted that the Extended Fault Memory had 2 instances of P0305 codes (cylinder 5 misfire).

From other posts, it seems like this is likely just replacing plugs + ignition coil but the dealer is brushing off the code as "normal" (sensors do this, yada yada...). Given some of the issues with dealers and CPO cars, wanted to get a broader set of opinions.

1. Is having 2 instances indicative of an issue as the shop suspects?
2. If yes, are there possible remedies I should look for as I'm negotiating?

Thanks!

I’d tell them to replace plugs and coils before I considered buying.

Especially since it is supposed to be a CPO, they need to replace the plugs and coils.

Thanks. Dealer is refusing to replace plugs and coils since they claim it’s not on the PIWIS report, and would anyway need to be an active misfire for them to justify any work.

It’s certainly a cool car but I’m not desperate for one. Would it be reasonable to ask for some money off (1-2k) in exchange or could this issue be indicative of something else much worse?

You should let us know who this very cooperative dealer is.

I wonder if you can guess by way of reputation since you're also in the same area... I'm giving them the benefit fo the doubt since they've offered to pull a new report right in front of me (I'll look out for "readiness" to see if they've just tried to clear codes), but will certainly be sharing the name either way.

I only have experience with Sonnen Marin and it's hard to believe that they'd do that.

Thats a soft pass for me... especially since the dealership can easily change those two things out for less than $100 to appease a potential client.... Thats a big RED Flag for me.. but just my opinion, haha.
