You don't know that either. I doubt it though. Not everyone thinks their R is a McLaren.
So I was just gonna leave this, but I have a degree in economics and can do some math so...
~17000 R's made. So with replacements, let's say that they need an ultra conservative 30k of these higher spec items. This assumes all Rs are still on the road and that the part cost was amortized over the total number produced (this is a simple and accurate assumption in economics, fixed cost is spread evenly over the production run). Before this, the part cost ~$230 so lets say $250 to be nice and round. Assuming a conservative 20% markup that's ~$208 to produce, let's say $210. That's $6.3M The Takata settlement paid out more than $500M. But ok, that was for 32M airbags (but more were affected). So let's start with that as a proportional cost offset of about ~$15 per airbag savings before you even factor in marketing budget and brand loyalty. Volvo's published profit margin on their new cars is 8%. The absolute cheapest model you can get new today is the xc40 base at ~$35k. So (worst case) Volvo profits ~$3000/car. Like I said, the quality of my R has already encouraged one person to buy a new Volvo. I can't speak for all of us, but let's again be conservative and say that every year 10% of us diehards get a new person interested in Volvos. Half of those people end up buying new. So 5%/year on a diminished total number of R's remaining(let's say half just for good measure) means about $20.4M in profit alone if all anyone buys is the absolute cheapest base car. Let's divide that by the total number of airbags they'd have to make to keep all of us happy and get $680, plus the settlement cost savings gives us $695. Giving them a total "profit" of $485/bag produced and given away free.
Wow. Looks like over time they make money! Remember that $6.3M number though? That's less than 10% of Volvo's marketing budget. It's impossible to accurately describe the goodwill impact of this, but I'll try. Volvo is a brand built on a reputation for safety, reliability, and luxury. Gordon's p1800 is still going and is a factory supported car now. The p1800 was marketed the same way that the Rs were against their competition. Sure, no one thinks an R is a McLaren (although you should look up some of the really bad partner cars McLaren has done over the years, in a lot of ways it's better that some McLarens lol). But people do compare them to BMW's M cars and Audi's S cars. So let's think of this recall in terms of Volvo's current marketing strategy. Safety, check. No one is debating this, the new part is safer. Reliability, check. They're making available a part for an older car. Luxury, well this is a big miss. So let's see how making the right part can make a difference in terms of their current marketing. The tagline for the luxury xc90 is "For Life." I'm not a marketer, but that's an ad right there. "When our 20 year old luxury model needed a fix, we made sure the cars were perfect. Volvo is for life." Run that as a full page ad in some car mags and I'm pretty sure that you'll attract people.
