P80/P2 TCV Compatibility

Post by bmdubya1198 » Thu Nov 14, 2019 9:48 pm

Quick TCV question... my cousin wants to order a new TCV now that his car is tuned and the boost is acting very strange, and we can't figure out which one to get. I got PN 30670448 for my 2000, but that PN is apparently only for P2s. Which is odd, because according to FCP Euro, it's also compatible with 2000 C70 and V70 models. Seems to be an error on their end.

The other TCV part number I'm seeing is 9473212 which on most parts sites shows "2000-2002". FCP shows this PN as an alternative for 30670448, so maybe it was superseded.

Weirdly Viva's website shows 30670448 for all P80 and P2 models, while most other sites just show it for P2s.

Now this is where it gets interesting... there's also 9155936 listed on FCP's website that shows to be the correct part for a 1999 model, yet Volvo parts sites just say "contact your local retailer for more info" . It's also double the price on FCP for the Pierburg one (no sense in paying for a genuine Volvo TCV).

It's just a little confusing being that all of these cars are ME7 (well, except '98s and the Nedcar S/V40s) but they use different valves.

So I guess the two part numbers I want to focus on are 9155936 and 30670448.
Does anyone know if there's any difference between these part numbers? If so, maybe that's what's causing weird boost issues on my car... but I won't get into that right now :roll: .

I've wondered about this for a while as I've seen more than a few people using S60 T5/R TCVs in their P80's, but most of them have somewhat modified cars. I'm not sure if that is a causal link or purely coincidental. Either way I'm very interested in the answer given no-one stocks or supplies P80 TCVs where I am.

That's why I'm so confused... some say that they're the same, others say they're different. I can't find any info on any forums, and if the P2 TCV is different mechanically (which I highly doubt) it could possibly cause issues with boost.

I'm also interested if you find out anything ...

FWIW I bought this Pierburg 728197160 for my 06 but ended up putting it into my 98 and it seems to be working great. https://www.fcpeuro.com/products/volvo- ... 49#fitment

Great... just one more PN to throw into the mix! Lol
Good to know that it's working well in the '98.

I'm gonna post this over on Swedespeed too... I'm sure one of those guys has an idea.
