Hey guys, my 13 Treg TDI now has 130k miles. No issues except blower motor that I'm changing out today.. in hindsight wasted $$ on 100k warranty. I've owned since new, kept up with maintenance, however, I've always filled up at most convenient stations when tank was near empty with no additives. I'm considering spending at least $3-4k to repair the sagging headliner, remove dents, new tires, full detail and various maintenance items. My primary objective at this point is to avoid being stranded while frequently traveling long distances with family. Should I consider replacing the HPFP, water pump with belt? Anything else?

130k miles and no issues with the HPFP? Leave it be.
Inspect belt condition before replacement.
Flush your fluids.

If it ain't broke has been my mindset. Just concerned that my HPFP could be compromised since i've never gone out of my way for top quality fuel and i typically let the tank run low. Ive changed multiple water pumps over the years for prevention and seems that 11yrs and 130k miles would be time to change but i'm not sure of stock pump lifespan.
I've researched and cant find if anyone proactively changes the HPFP. Appears to be a big job and I assume its expensive.
Belt still looks good. All fluids are consistently changed.
It has been a great car! still drives close to new.

I'm going to ****ing lose it the next time this retarded question is brought up. The HPFP is not a maintenance item for ****'s sake. It either works or it doesn't. The end. Leave it alone. I see this bullshit on Reddit all the time and I wish it would die
Do some ****ing research. I'm so sick of all these newbies coming in asking the same bullshit questions. Stay off of Reddit.
Why does an HPFP blow? Once you learn the basics of how these things even operate you'll know how stupid that sounds.
How many miles does your transmission have on it? Think you should replace that too preventatively?

Despite the aggression… I have to agree with VFL.
It seems very likely that the HPFP failures are sudden catastrophic failures that have a fixed rate of occurring- e.g. a new pump is likely no more reliable than an old one. A high percentage of the documented HPFP failures still occur on newer pumps, and these failures were known almost immediately when these vehicles were new.
In general, a lot of parts failures in engineered systems follow a poisson distribution for failures, meaning the probability of failure is the same per unit time, e.g. the parts don’t actually age, and a new one isn’t more reliable than an old one.
Now that we have protection kits to contain the damage from failure, it’s much less critical to try to prevent a failure.
Personally, I will just install the whitbread kit and if my pump fails, swap in another one, possibly even a good used pump.

@casioqv brings up a good point, the new Whitbread kit is a great option for cheap insurance.
Another option? Keep some lubricity additive on hand and use it for every tank. Stanadyne, PowerService, Howe's... all brands I've used over the years. I recommend whatever's consistently available as best. What I look for in a quality additive is one that will help emulsify any water that may be in the station's tank to prevent damage to your pump. The other main reason is the boost to lubricity, which is necessary when running ULSD. Any cetane boost is tertiary.
Where's that recent thread where a guy insisted on replacing his HPFP due to mileage even though it was working fine, and we told him here and on tdiclub not to waste his time and money, only for it to fail catastrophically?

I apologize for not keeping up with your Signal chat man.... I see it's resulted in some recent rage.... will reach out to you shortly!
Let me get my couch cleared off for you.... talk to me!

So you bought a warranty when you already had the same powertrain warranty from factory?
And then years later, the AEM one?
Can you elaborate on that a little. What exactly have you done as part of "maintenance"?
I'm not a newbie, joined in 2013 when i bought the touareg. Haven't been on this site in over a year, they required email confirmation before i could post. Had an old email address and couldn't find or get answer from moderator on changing address.
Been on car forums for many years.. I know to research thoroughly before asking questions, otherwise one of the hostile cool kids will start juvenile name calling. Thought I did my research.. 10 yrs of empty tanks, fuel from the grocery store and no additives has me concerned.
Trying to identify any weak points that could strand us on road trips. I've kept up with oil changes, fuel filter, and all other fluid flushes, with exception of changing transmission fluid/ pan gasket. I like to DIY, have quickjacks and most tools... for trans fluid I'll probably take to shop as it looks like a mess on my garage floor is likely. Guess I should do it soon?
Considering a macan, cayenne or X5 but this car has been so reliable, still drives great. We've been travelling across the south and midwest for daughter's tennis last 6 yrs... touareg's been used most trips. My daughter considers the toureg a lucky charm. Don't want get rid of it.. also want take all precautions to minimize chances of being stranded, whether that's spending on preventative maintenance or buying a newer suv.

I think it's safe (?) to say, if your habits had done any damage you'd know by now. That said, additive is cheap insurance if you can get into the routine. As well as filling up again when the light comes on, and not running down to vapour would go a long way.
Speaking of reliability... have you tuned/deleted yours yet?

So does that mean you've already had coolant, steering & brake systems flushed?
What about diffs, transfer case, battery, accessory belt, idlers & tensioner?
What are your DPF stats like?

I know this doesn’t necessarily apply to tregs , I own a 2012 TDI, I have been driving tracto trailers since 1987. I have never in that time had a fuel system failure on any of the engines I drove. You name it everything else …..but no fuel system failure.
I only run my Toureg hot and on the expressway. I got the tickets to prove it😎 I have had zero problems 122 k miles.
preventive maintenance is pedal to the metal on the expressway
