That’s what they want you to believe. ;)

I bet all the cars at the PEC are using E10.

Octane, ethanol % and performance are some of the different attributes of petrol and are mutually exclusive. That is why a change in one does not affect the others

Im sure if the % Mix was 99.9% Ethanol, 0.1% Petrol there would be.

I have never had a need to take my cars out the UK, My time is very precious so as much as I would like the long drive, and enjoy that. Its far easier for me to hire a private jet to go to europe and have that travel company facilitate a driver and car for myself and/or my family for the period,so hopefully that helps as an answer. :) :)

Quick update from today:

Car has been back and forth from the garage and is now there for the next few days given then can’t find a fix.

Basically they’ve now installed a new high pressure fuel pump, a low pressure pump (I think this is located in the fuel tank) and a fuel sensor and it still persists. The dealer isn’t sure yet what’s causing it so it’s a process of elimination.

To recap, it’s only 8m old, 8k miles and a Macan S. Quite concerning! Oh and the fuel is fine so it wasn’t that. What to look at next? Coils / injectors?

I think the problem is there are so many sensors and micro-processors on cars these days that any one failure could cause issues. You’d expect any actual failures to show up on the diagnostic devices though.

Arguably the “only 8 months old” thing can be seen as actually quite good ( for you ) as all this will be covered under warranty. And as much as I am not shy when it comes to pointing out the failings of Porsche, or the Macan in particular, I do feel that in this instance you’ve just been really unlucky.

I hope they get it sorted soon. Presumably they’ve at least given you a decent loaner.

Yeah true!

Tell me if I’m overreacting but I guess I’m concerned / disappointed as this is the most expensive car I’ve ever bought and I expected a lot from Porsche as a result, so now not sure how I feel about the car…
