Hello all,

So recently bought a 2018 macan gts with 100km on the clock, all was going fine until I got a warning on the dash. I've just taken it into a garage to have the codes read, and this is what it's come back with:

The guy has said it's likely the mechatronics that's causing this, and has given me three options:

1. buy a new mechatronics system
2. find a macan that's being broken and get the gearbox and mechatronics from that
3. find a guy who can refurb my current one.

Just wanted to see if anyone else has had the above issues, what caused it, and how you fixed it.

Thanks all

The dealers will want you to replace the whole transmission. The indies will replace the mechatronic unit whick will still run you approx. $5000. I was able to repair the same DL501 DCT from an Audi RS5 this year by replaceing 2 Borg Warner VFS Solenoids (VFS Solenoid 50228) and the Variable Bleed Valve (Borg Warner 50229). There are quite a few threads in the Audi forums regarding this failure. These solenoids control the transmiision oil flow and oil temp. When they fail, the transmission will over heat and go into limp mode and won't go into Drive or Reverse. I hope this helps.

Before changing these solenoids, I replaced the electronic control board which cost over $650, but it did not fix the problem. Yes, I had to open up the transmission twice and buy 2 sets of fluids for this repair. I still saved a ton because the dealer quoted $16K to replace the tranny for the RS5.

Thanks for this, the garage that I took it to has recommended a gearbox specialist, and said he can probably pull it apart and recondition it, and that it could just be the solenoids that need replacing. So I'm hoping if I go down this route I'm not going to have to fork out for a new mechatronic unit.

Am I ok driving the car until I get it looked at, or is this something which is going to get worse / do more damage the longer it's left?

While I hope you get this issue sorted ASAP and at a reasonable price, stories like these just give further verification why one should never own a German vehicle out of warranty.

😨
I think a lot depends on which generation, the model, and potential known issues. Now granted the newer cars do have more technology which complicates long term use but even stilll the cars are reliable .

I would not feel comfortable owning a first generation Macan 10 years. I wouldn’t feel comfortable owning a 996 either. However I would feel comfortable owning a 996 turbo. So One can split hairs .

I would feel comfortable owning a second generation Macan. I don’t know if I’d want to keep it 10 years but I think a person could squeak out two more years which is where a CPO would carry it beyond the factory warranty. That would make it six years to say I think it would be safe.

A 20k mi 2015 Turbo I was going to buy threw a code and could only go into reverse. Dealer quoted $20k for a box replacement. Their position is that these boxes can't be opened and you need to replace them when something goes wrong. The owner took it to a mechatronics specialist who fixed it for $1,500. It was just the solenoids IIRC. I didn't buy it because a better option presented itself but I otherwise wouldn't have had an issue with it. These boxes are solid but mechatronics don't like heat and if you drive them in econo mode in stop-and-go traffic, the oil will deteriorate prematurely and put the box at risk.

Never ever take it to the dealer.

Also, note that while Porsche loves to claim that the PDK in the Macan is a Porsche box, it's not. Macan's PDK is built by Audi at the Kassel plant and licensed/modified/rebranded by Porsche. To what extent still remains a mystery but it seems to be mostly software tweaks. It is not built by ZF like the PDK in 911s.

In other words, the PDK in the Macan has been around for a decade and it's very reliable. There are also enough indie specialists who can fix them.

Thanks for this, I'm hoping a specialist can get it sorted without me having to replace the entire thing. If they're not a fan of the heat, I guess that doesn't bode well for me! I'm in Dubai and the summers here can hit the 50s!

More than likely you will be able to fix it. Once fixed, just drive it in manual or sport and change the oil before the suggested interval. You’ll be fine. In eco mode these transmissions shift gears a lot. Manual or sport reduces shifting and that reduces heat.

I would not drive it before fixing the issue. When the unit is running too hot, the clutch plates will get damaged and that repair will get more expensive because the whole tranny will have to be removed to access the clutch pack etc.

What are the physical symptoms? Did error come back on restart?
An error comes up on the dash every time the engine starts, something along the lines of:

"Engine control fault, consult a workshop, driving permitted"

There is a slight judder when pulling away from a stand still, but only a very slight one, maybe 2-3 quick, soft judders.

I've had it read by two different garages, who have both reset the code, but after around 50km of driving it comes back again on every start-up.

Going to speak with a gearbox specialist tomorrow, and see if anything can be done.

I’ve had that error code from bad gas. Seems like you need a proper diagnosis.

Ok so an update on all of this, it's the control unit on the mechatronics which has given up. I've been told that I can't purchase this control unit, as it's not sold separately, so my two options are:

1. new mechatronics unit
2. try find a used control unit from another Macan.

I feel happier going down the first route, but the problem I'm facing is that nowhere in Dubai can get hold of a new unit, I've been given lead times of 12 weeks for the part to even become available.

Any advice on how I might be able to get a genuine unit quicker? Will Porsche talk to me? Or would they expect to supply and fit in-house (at a much higher cost)... My wife is actually German, and travels back to Germany with work quite a lot, would she stand a better chance getting one there? If so, can anyone recommend where I start looking?

Thanks all

How about ebay? Or the thread right around the corner where someone is parting his macan?
