bandit_287 Posted July 15, 2020 Report Share Posted July 15, 2020 (edited) In a world of ever evolving technology and progress with research and development cars are becoming more reliable than ever however I met up with a friend this week with a 718 that’s just under two years old, in the time he’s owned it it’s needed two new turbos and a water pump. I was very surprised to say the least. Can any other 718 owners report any major issues? edit, it’s done 21,000 miles.

EVO Chris Posted July 15, 2020 Report Share Posted July 15, 2020 That is very disappointing to hear I thought the 718 would be rock solid (had enough practice)....I was hoping the 718 may be a future purchase so will keep an eye on issues like this.

RoddyT Posted July 15, 2020 Report Share Posted July 15, 2020 Not had any issues other than tyres only lasting 20,000 miles.... Quote Link to comment Share on other sites More sharing options...
Patt Posted July 15, 2020 Report Share Posted July 15, 2020 All turbos need to be looked after by the owner/driver. If the drive hard from cold and turn straight off without allowing the oil to cool - problems will follow... most daily drivers do not know or allow for this and are not advised by the salesmen either !

Changing my rears on Monday, just over 10k, seems about normal for me. Apparently I often drive it like I stole it 😂😂.

Greenman Posted July 15, 2020 Report Share Posted July 15, 2020 I’ve not heard of that many issues with the 718 generally, but to be fair the engine was new so it wouldn’t be surprising if some issues did show up. The 981 engine was just a development/refinement of the 911/Boxster engine from the previous generation so you would expect it to be pretty reliable (which I think is proving to be the case). The 718 was pretty much developed from the ground up, so I think it’s quite encouraging that there haven't been more reports of engine issues in this generation.

Manicatel Posted July 16, 2020 Report Share Posted July 16, 2020 I had a “cooling system fault, service required, contact dealer” message appear. It was a split pipe apparently. Other than that, no issues to report. Quote Link to comment Share on other sites More sharing options...

Is this still an issue on newer cars? I thought it was only an issue on old school turbos where the oils weren’t up to spec and the installations not particularly refined. I’d be doubtful of Porsche producing a modern mass market sports car that you need to idle for a couple of minutes after a spirited drive.

I’m not sure what porsche (or anyone else) can put in place to mitigate this? Sure I imagine that turbo manufacturing techniques, and oil delivery are likely improved from 20/30 years, but they still (as far as I know) use engine oil to cool the turbo. The turbos get extremely hot under load and if no oil circulation then clearly the oil that is there will become very hot. mobil 1 is supposed to be ok to 260C. As far as I can tell turbos can easily get up to 1000C. So unless the oil pump is kept running for period after turning off I think I would always be inclined to idle for a minute after any sort of turbo load before switching off. Warming up is just a slightly more pronounced issue that applies to thrashing any car from cold. Quote Link to comment Share on other sites More sharing options...

CMA Posted July 16, 2020 Report Share Posted July 16, 2020 At the Porsche experience centre at Silverstone, they didn't give a monkeys about cooling the 718 when I went for a drive there. Just jump in, drive hard, park up and go to lunch. Quote Link to comment Share on other sites More sharing options...

Richard Hamilton Posted July 16, 2020 Report Share Posted July 16, 2020 (edited) I've also heard of a water pump failure on a 2017 718S recently. The cooling system is highly complicated, and a nightmare to bleed (I am told). There are a couple of updates to the header tank filler neck and level sensor on pre 2018 cars too.

Pezky Posted July 17, 2020 Report Share Posted July 17, 2020 Mine has done 22k miles, I've owned it a year. From my pre-purchase research, they are very reliable. I'd heard about the header tank/coolant sensor issue. Quote Link to comment Share on other sites More sharing options...
bobar Posted July 20, 2020 Report Share Posted July 20, 2020 My 2016 has covered 18,000 miles. The only fault so far has been the coolant pump failed. It was replaced under warranty. Quote Link to comment Share on other sites More sharing options...

Oil is only used to lubricate the bearing and sometimes waters used to cool the turbo and/or speed up heating the water for the engine from cold, Uswd to remove the water cooling on Cosworths to prevent overloading the cooling system especially on track .....
