The 40000 mile service was done a month ago and there was no time to investigate the transfer box. The car went in a couple of days ago for the transfer box investigation, and it was scheduled for replacement but waiting for parts. I also had a squeak from the front left which turned out to be a failed wheel bearing. This is obviously chargeable because I chose to self insure! They also spotted a problem with one of the rear tyres, so 2 new rears. Oh well, they would need replacing soon anyway. Does anyone mechanically knowledgeable think transfer box and wheel bearing failure could be related? Magically a transfer box arrived today and that is being swapped, ready for collection tomorrow.

I can’t see how the two could be related, at least not directly. I guess perhaps a failure mechanism for both could be something like driving through flood water.

Thanks Nuclear Nick, I did go to the lakes recently but managed to stay out of them 😀.

Hello everyone, I am about to bite the bullet and buy a 2015 Macan Turbo. During my enquiries I discovered that the car has a warranty on the transfer box until 2022. Is there anything I should be looking out for? As I don’t intend to service it at the main dealer and I’m not sure where they stand if I take it to an independent. It’s going to pie performance for a PPI, so I could potentially ask them to check for any issues.

Timing cover oil leaks.

Apart from that, fairly solid car

Why are you not servicing it at an OPC?

If it has full OPC history thus far for the sake of £600/£1200 for 20 and 40k services which you may get around half price for Indy service it pales into insignificance against the petrol cost.

If it’s already outside the OPC network then i presume you’re benefiting from the lower residual value of a non OPC FSH car?

The car is now 5 years old, I didn’t think that servicing with a specialist who are knowledgable about porsches would make any difference to the residual value. I certainly wouldn’t care as long as I know the car has been properly maintained. It does currently have a full opc history.

Thanks for the feedback though I’m pretty sure they will report back on any oil leaks. I was more curious about little things that may not be so obvious:

Another plea for information regarding the transfer box and bearings. I have just had my front near side wheel bearing replaced and and paid for it and the squeak/squeal is the same as before. OPC offered to order the parts and replace the prop shaft centre bearing in exchange for gbp 1200. I declined because I wanted to hear the car after the wheel bearing replacement first. I suspect I have paid for a new wheel bearing unnecessarily. Perhaps the prop shaft centre bearing failure could be related to a failed transfer box? I’m speaking to the Porsche technician tomorrow.

Can’t help with your bearing problems unfortunately. However, I had the second transfer box fitted last week exactly one year after the first one. The car is just four years old and 21k miles. I have no bearing noises as yet.

Again, I can't see how these two are likely to be related. Bearings do fail through normal use, usually after many miles though in normal conditions. Things that can accelerate wear in these components could be extended use in harsh environments such as salt water, sand, towing heavy loads, temperature extremes and wading, as I mentioned before. I'm not suggesting you've been doing any of these things, random bearing failures can occur at any time without a direct cause.

Thanks again Nick. I’m just a bit miffed by the misdiagnosis. let’s hope the next one fixes the squeal!
