This.
and yes, probably just the stubborn airlock, but a garage should easily find such, but hey, if the computer can't find it those days they have to go old school ;-) find the high points and bleed, maybe disconnect a hose if there is no bleeder, but come on, a garage should have found such easily and not give it of without it working!!

Do you seriously think any garage would hand a car back after an engine swap without being confident the cooling system was fully bled?

Once you have bled it, run the car up and cooled it down untold times and the heater is working properly the mechanic would assume it is fully bled.
If there is still an air lock somewhere which obviously cannot be seen and isn’t ‘easy to find’ how would they know, it isn’t going to come up on a scanner?

Having rads and engines at opposite ends just makes it a harder job, no matter who does it, before the inevitable OPC bashing starts.

I’m beyond panic, just utterly fed up with it all.

This should not be happening, plain and simple.

Courtesy car 4 will arrive tomorrow- even that was a battle - they apparently need to see my V5C, but that was sent back to DVLA informing them of the new engine number, with a covering letter from Porsche.

Sorry to hear, for me sadly it is no suprising that Porsche continue to do crap maintenance and service for their cars even for special models like GTS 4.0. I had a similar situation before with much older Porsche but technology and service gone beyond nowadays, they just need to do a decent service which they can not even apparently. Hopefully you can get a good resolution, last thing you want is to deal with car issues on such special car with a well known manufacturer

Sorry to hear of all your troubles. Its only us fellow enthusiasts who can really understand how upsetting this can all be.

The report of the 4.0 failing is worrying. Is there a lot of this happening?

Any warning signs? I've always thought that mine sounds a bit rough and noisy on cold start up - mechanical noise (sounds like top end) not exhaust - and it certainly doesn't sound like a smooth engine at idle but it does get a bit quieter as it warms through. Anything to be concerned about?

[Jazzer]

That sounds pretty normal to me.

Mine gave no indication whatsoever that there was impending doom, failing in fact on a slow drive home on a Sunday afternoon.

My biggest worry is that, apparently, they don’t know exactly what went wrong; that being the case, how do they know they have fixed it??

As @Jazzer says, likely normal. There are some pretty strange noises and rumblings from the GTS 4.0 on warm up. I think it's actually from induction or exhaust, but sounds quite mechanical, deep and growly. Mine generally starts doing it between one and 3 minutes after starting, and quietens down within a couple of minutes. Has done so pretty much every weekday morning since October, so I'm not concerned that it's abnormal or causing any sort of deterioration.

I doubt very much that having stripped the engine down they will not know what the cause of the failure was.

They may well be keeping that to themselves, knowing full that there is a fair chance that whatever they share could be all over the internet in minutes.

[Forester1965]

On what basis could they withhold it?

Not suggesting if the customer asks what caused the failure they would say we are not telling you, he has been inconvenienced big time and is entitled to an answer.

What I am saying is the answer will be worded carefully knowing that whatever they say could be all over the internet in minutes.

I realise that, hence the 'apparently'.

OP are you saying the replacement engine has now failed as well or are they the OPC unsure of the reason for the low coolant, but the engine is still running ok?

[Jazzer]

The second engine developed a low coolant warning within 100 miles (mostly to and from the OPC to restore functionality to an instrument cluster, something they missed...!).

I've yet to hear what caused this warning, but the Porsche assistance guy, incredibly the same one who recovered me the first time, expressed concern about a second failure being about to happen - it could be an airlock in the coolant system, it could be more.

The whole experience has been an indescribable tale of woe, costing me time (lots of time), money, cancelled appointments, cancelled trip to Scotland, ruined holiday weekends (plural) and total embarrassment having to have my as-new Porsche recovered twice in front of my neighbours, both at my previous home and at my new one, where I moved smack bang in the middle of all of this.

So I'm now exploring my options and thinking about how to proceed.

[Youforreal.]

Just sell the Porsche and move to another brand
that these type of things don’t happen with.

Terrible to go through this.

I'm assuming there is still an option to reject the car and take your money back ?

Sorry to hear about this, OP.

My best mate has just finally emerged from a similar nightmare, but a lot worse. It's like your story on steroids...

His 4.0 718 had TWO engine replacements, and the supplying dealership's incompetence and arrogance are impossible to exaggerate. He had a similar coolant situation and missed a meeting as a result, and when he collected his car after one of the endless visits back to the dealership they handed it back to him completely devoid of fuel. They also damaged the car pretty comprehensively, it seems it spent months living outside at the OPC.


He's managed to finally agree terms with them to get shot of it in the last couple of weeks. Nobody at the OPC or Porsche UK ever really apologised properly and certainly nobody took responsibility. He might write the whole awful tale up at some point and if he does it will hopefully get posted here, amongst other sites.

None I can think off tbh but then again I’m happy with my two porkers and the op is at his wits end.

Maybe at some classic Porsche garages? were they probably still work with their hands and minds instead of (mostly) computers?

Car no longer ours but we still have a 997, albeit with a Hartech 4.1.

As a current 997.1 C2S owner, I'd be very interested in your take on the difference between the OEM 3.8 and Hartech 4.1 in terms of drivability and performance.

[GT4P]

This worries me a bit as it started with the whole engine replacement programme for new factory cars built early 2021 and now we have started to hear of random failures of the 4.0 engine in the 718, are we seeing another episode similar to the 996/997.1 failures??
What with PADM issues across all models since 9x1, turbo failures of 991.2/992, windscreen issues on 992 and so on, add to that the dealership game playing and overs market of recent years it doesn’t inspire one to purchase a modern Porsche!
