We have totally abused the purpose of this thread. I would be happy if an admin could cut all the commentary out and dump in another thread.
lets just say as humans, we are not very good at reacting to risk in a rational way.
folks are afraid to fly, even as the danger driving to the airport is higher,
we accept heart disease, auto accident deaths and firearms deaths, but go bat sh*t for a virus which is easy to contain with basic public health measures.
HPFP failure is expensive, and we have seen reported here several hundred cars (what is the count, anyway)
but no qualitative comparison with DPF cracking or turbo failures. or DMF failures or oil pump shaft failure, or accessory belt shredding and taking out the timing belt for that matter.
I know it is an issue, but like to have the numbers, if at all possible. there is nothing posted here that says a HPFP is more likely (or less likely) to fail between 100k and 200k than between 0 and 100k miles. (or 200k to 300k)
there is also no way to compare if you would be better off if you put a new HPFP in before it fails, (and a few stories of failures likely induced by too much messing around with the fuel system)
it does suck, esp if it happens to your car.
but for most of us, (should I knock on wood?) this is more likely to be a non-issue, even if we keep it for 15 years and put 300,000 miles on the car.
KBB on my JSW right now is around $5k. it also has a slightly cracked DPF. in the unlikely event the HPFP crapped tomorrow, I could spend $5k and still have a $5k car with a cracked DPF.
anyway, even if it is 2% or 5%, or even 7%, I would not fight with someone who wanted to call it rare..
if you want to call that high, I don't have any problem with that either. (but somehow felt the need to ask for a number when you thought you needed to question the residence of a fellow member)
I just wanted to stick up for Matt, who was making a couple valid points (as it seemed to me)
there is a concept known as expected value, where you multiply the probability by the cost. (this is how insurance companies make money)
if the failure rate was 2% per year, and the cost was $5000, the expected loss would be $100. (per year) so if these were the rates, it would be a profit center for someone to sell HPFP insurance for over $100 per year, plus whatever admin costs are.
