Don't you have junkyard somewhere where you could just grab a unit from a wrecked macan?

Not sure which specific VW has the same mechatronic unit. Did he specify the model? I know audis are somewhat similar but never heard about VW.

He's told me he can fit it to my car, clone my current software, and put it onto the new mechatronics unit from VW.

This guy is either a genius or he's full of chit.

There is no VW model which uses this DL501 transmission. It is used in some Audi models, S4, S5, RS5.

Apologies all, it's from Audi, not VW. He did say that it was the circuit board that is causing the issue, and that when he reads the Macan codes there isn't the sensor for the clutch, even though there is on the Audis with the same unit.

Anyway, I've bit the bullet, Audi mechatronics unit is on it's way, and I'll soon know if this fixes the issue or not!

Again, thank you all for the help and advice, really do appreciate it!

Let me know the Audi part so I can order it myself. I too I’m having the same issues and would love to get it fixed without having to pay 20k to the dealer

Hello all, little bit of an update!

So after waiting 3 weeks for the new mechatronics to arrive from Europe, the part was fitted, and all seems (fairly) fine.

All faults have gone, the car flicks through the gears much quicker and smoother, and it feels like it has more "get-up-and-go".

However... I'm noticing the car clunks when I come to a stop, going from 2nd to 1st, and then almost seems hesitant to pull away, again clunking and juddering a bit as it goes through 1st and into 2nd.

As this mechatronics is from an audi, I'm not sure if it's an issue with the unit and it not being happy that it isn't a Porsche part. But the mechanic did also mention that the dual mass flywheel is on its way out, and will need replacing in the near future. From what I've heard this isn't an overly expensive part as such, but there's a lot of work to actually get to it, and replace it. He's said that whilst the transmission is out, I might as well look at putting a new clutch in, and gear position sensor.

Car will be going back to the garage and plugged in to see what may be causing it, but I'm interested to know if anyone else has had this issue (regardless of mechatronics being replaced), and what it might be. At this rate, Christmas is cancelled in our household!

The entire transmission is an Audi part....if you buy any of its parts from a Porsche dealer, it is the same part in a box with a Porsche label, and a higher price.

Concerning the clunking behavior, sounds like they need to run the numerous transmission adaptation/calibration routines with a scan-tool (PIWIS, Autel, X431, iCarSoft.....). These calibration routines need to be run whenever the Mechatronic (or some of its components) are replaced.

Why do they think the DMF needs to be replaced? I don't that has anything to-do with your clunk issue.

@YorkshireDan respectfully, I would get a second opinion. Having to replace these units is highly unnecessary unless you're speaking with the dealer. Consult a mechatronic expert with experience working on these Audi units. Most deficiencies can be fixed for $1,500 to $3k with labor. Good luck.

 

[YorkshireDan]

Thanks all, the guy I've taken it to is regarded as the best in the region, even the Porsche specialists take cars to them if its anything gearbox related. I'm booking the car in with the main dealer for the transfer case recall, in the hope that this might help with the clunking from 2-1-2.

The mechanic said that the clutch usually needs replacing around 160k km - which sounds about right to me?...

With the DMF - he mentioned a clicking/clunking noise which could be a sign of the bearings on their way out in the DMF.

He's offered to plug the car back in and see what the computer says, it may be that it just needs to be calibrated properly.

All of this is way way over my head, so apologies if I'm sounding stupid or naive with all of this.

 

[AvidTurboPP]

Sounds like you're in good hands. Hopefully things get sorted out quickly. Keep us posted.

 

[YorkshireDan]

So... A further update to what seems like a never ending saga!... Mechatronics has been replaced as mentioned.

We noticed a slight judder when the car goes from 2nd - 1st, and 1st -2nd, especially at low speed.

Took the car into Porsche, who recon it needs a new transmission [sic] transfer case. I'm hoping this is covered under the extended warranty, but I don't know if this was a world-wide warranty, or region specific? Porsche have said they need to contact the head office in the Middle East to get approval, and then it's a case of if they have the parts, or need to order from Germany.

Seems like it's never ending at the moment!

This thread has shifted more from me looking for advice, to keeping you guys updated. I didn't know anything about the extended warranty for the transmission [sic] transfer case, where Porsche should replace this free of charge, and if you've paid to have this done, they will refund you the money - just in case anyone may be interested. HERE is a link to one of the articles about the warranty for anyone who wants to look.

 

[VAGfan]

Do you mean that Porsche said you need a new TRANSFER case?

 

[YorkshireDan]

Do you mean that Porsche said you need a new TRANSFER case?

Apologies, yes it's the transfer case. They've just called this morning to say Porsche have approved the replacement of the transfer case, and the car will be ready to be collected later today.

Will let you know how we get on!

Good luck !!

New year, new update!

So the car had its transfer case replaced by Porsche under the extended warranty. They didn't pick up on the fact that the mechatronics unit in the car is actually from an Audi, as I was a bit worried this might flag up, and void any warranty with them, but thankfully nothing was said.

One thing I had noticed since the new mechatronics was fitted, is that it is a little clunky shifting from 1st to 2nd when pulling away, and there had been a couple incidents where I'd come to a stop at the lights, still in drive, press the accelerator and the car would just rev, but not actually move.

I did some digging around on the forum, which is a treasure chest of knowledge, and font a post from almost 10 years ago with a similar issue, and it was resolved by updating the PDK software.

So I took the car back to the gear specialist, who plugged it in, made sure it was on the latest software, and since then I've had no issues with it at all, I finally feel like I can start to enjoy the car!

Just wanted to give a huge thanks to everyone who chipped in with suggestions, seems like I got there in the end!

 

[Teddis]

Great outcome !
But what did replacing the transfer case solve ??

Absolutely no idea if I'm honest!

After the mechatronics was replaced, I started having some clunking/juddering between 1st and 2nd, which when I was researching about the transfer case, it sounded like that could be the cause (on Porsche's website it says "This interruption in traction can be perceived as jerking or longitudinal vibration during acceleration.")

When I took it into Porsche, they agreed that there was a recall on the car for the transfer case to be replaced under warranty, so they replaced it.

As this didn't fix the issue, it went back to the gear specialist, who put the latest PDK software onto the car, and so far all seems fine.

In hindsight, I think Porsche would have replaced the transfer case regardless, and I believe it's the same for anyone with a 2014-2018 Macan. As we didn't buy the car new, we wouldn't have got an email saying the work needs doing.

 

[AvidTurboPP]

Glad things worked out for you in the end. Not a nice way to start your ownership journey but hopefully it's in the past now.

 

[YorkshireDan]

Another week another issue!

Car was due a minor service, so took it in to the specialist.

Flagged a few issues which I'll need to address, some more urgently than others.

The engine mounts have degraded. Due to the heat and dryness we get in Dubai, it's caused the rubber in the mounts to start to perish. He's said they're "OK" for now, but at some point in the near future they'll need replacing.

The other slightly more concerning issue, which will need addressing asap, is the driveshaft support bearing.

The mechanic mentioned that the OEM part for this can be a little pricey, but has recommended a company called JBX, who apparently deal more with VAG cars, but do also seem to make them for the Macan

Another month... Another repair bill...

So my 2015 Macan Turbo's mechatronics unit just failed. It got the "Gearbox Fault possible no R-gear. Possible to drive on" error. It lost reverse and 2, 4, and 6th gear. My mechanic had a Porsche tech confirm that it is the mechatronics unit. I was given the option of buying a new unit from Porsche and with all the labor it will end up around the 5200$ mark. From this thread I brought up the option of buying this kit, https://www.shenghaiautoparts.com/s...-0b5398048-transmission-solenoid-and-internal-wire-harness-repair-kit-for-audi/

He said that he is not sure if it would need to be reprogrammed after the rebuild and if it did, he wasn't sure if he could do it or not. If not, the car would have to go to Porsche to get reprogrammed and he wasn't sure how Porsche would react to it since they are recommending a new unit. Has anyone gone the rebuild route? It is quite a bit cheaper, but I don't want to go down that road if I'm going to just have to buy a new unit anyway.

Thanks!
