Replacing & Registering the Battery

Hopefully I will not need to do this for 3-4 years but I’m curious. Manual p. 314 says only have done by Porsche dealer & you cannot tell what type of (aftermarket) battery will replace the genuine Porsche battery by the markings on the battery. WTF?!

I like Interstate brand. Often better quality than OEM but, that is for lead acid, not sure for AGM.

So, has anyone here had to replace their battery & did you have Porsche do it & what did it cost you?

I finally took a look at my battery which is under the trunk floor in front of the Bose SubW (After lift the cargo floor, must lift carpet & then lift another cover to view & if need to access/change it--would need to remove collapsible spare tire!)

I see mine is 92Ah.

I searched & found Gaudin Porsche offers two; a 92Ah & a more powerful 105 Ah.


958-611-105-21
BATTERY 105 AMP HOUR MSRP $543.76, online price $351.05
Replaces:958-611-105-20

958-611-092-21
BATTERY 92 AMP HOUR MSRP $439.44, online price $283.70
Replaces: 7PP-915-105, 955-611-085-00, 955-611-092-00, 958-611-092-20

So, if you wanted the same battery you have now you’d get the 92Ah for $283.70.
My guess is that to have Porsche replace it for you you’d pay MSRP $439.44 + ½ hr. Labor! ~$500 to replace a @#$!!** battery?!

For Lead Acid batteries, you just need the dimensions to fit the space & the correct Ah & then it is reliability, price, warranty & specs such as CCA. How can it be that much different for AGM types? If, for example, Interstate made one to fit Macan that was the same size with more Ah for ~ $150 it would be tempting. For now, until I learn that aftermarket brands are available & work well, I’d probably upgrade to the genuine Porsche 105 AH & DIY.

I gave him my opinion as I work on a range of vehicles. When I talked to Autel in January they said they didn't cover any recent Macans (later than 2018). Also the fact I don't need to bother with a cable is worth it as well as the other remote functions.

Your MY2015 should be covered. Here is the answer I posted some time ago from Autel dated, September 2019:

The lowest tool we have that can read that would be a mx808 but i cannot recommend that because of the year of the vehicle you have the mx808 only goes up to around 2017 and some 2018 i would have to recommend a ms906bt that covers 2019 and going into 2020 but we do not have that software yet because of your year

The Launch covers 2020 and updates are very regular (I had at least 4 concerning Porsche) since I bought the unit. Good luck

So if I have a 2014 911, and a 2015 Macan Turbo, and wanted the "big four," oil, service, batt, and brakes. The Autel MD808 would suffice?
The only other thing I would like to do is raise boost display, for Cobb tune. Which can do that(probably not worth extra $500, if Autel can't)?
@siberian thank you for your opinion, you don't make choice easy! It's not that I couldn't do the extra $$$, for the X431, I would just rather not.
 
#635 ·
I decide I'll go for the Launch. So I start researching the launch x431... Can some one shed some light. There are USA, and Chinese versions? Different support teams?
Which one to buy, and from where? Amazon/eBay vs west coast, and/or their distributors? x431 Torque/Turbo? vs. x431 V pro mini?
Now I''m really confused! Thank You!!

Did you miss it? Forum member siberian has one. He's been using it extensively. I've seen several posts on its
capabilities - perhaps they were over in the rennlist forum?

If you can, check over there in the Macan subforum.

He's also provided an Amazon link (above?) for the model to buy - that site contains numerous reviews with pro/con comments
 
#638 ·
Some of the discussions mentioned ended up on the Rennlist forum and wasn't even in the Macan forum but the Cayenne one as it was started as a general thread to cover all electronic mods using an analyzer. It ended up by default being the Launch. The topic has been covered extensively here (if you look under battery registration) as well as under the previously mentioned Cayenne thread. I'm not going to rehash all that but simply to say that having been an extensive VAG-COM user for well over a dozen years on Touaregs, RS5s and Q7s one of the biggest benefits in the x431 over that and others is the wireless functionality where I don't have work having a bulky PC tethered by a cable to the OBD2 port.

An interesting video related to this, especially the last third of it. I don't always agree with what Scotty says, but most of the time his videos are spot on:

That's nuts!

Costco has the Interstate H8 battery for less than $200.

Okay, before I go down this road, would somebody confirm that I have all my **** together and am good to go:

All the information below is gathered from reading the 33 page thread repeatedly and watching videos.

1) Autel MaxiDiag MD808 Pro will program the battery.
2) Interstate MTX-49H8 from Costco works.
3) I don't require an auxiliary battery source while changing the battery.
4) After swapping battery and plugging in the Autel, activate connection by:
a) Turn on hazard lights.
b) Press brake pedal
c) Flash lights repeatedly
5) Enter BMS program by entering the following steps:
a) Go to Control Units
b) Go to Gateway Control Module
c) Special Functions
d) Battery Change
6) Input the following codes for 2015 Macan Turbo S into Autel MaxiDiag MD808 Pro:
a) Battery Capacity: 95AH
b) Battery Technology: AGM
c) Serial #: Must be 15 characters. Interstate will be 14 characters and add a space for the 15th.
d) Porsche Part #: Must be 11 characters. 958-611-092-21.

Am I missing anything? Is this correct?

Thanks

I was waiting for someone to give you the official thumbs up before I bought the MD808 pro. Radio silence around here.

Atnsw decided to contact me privately, which I told him was not a good idea as these are items that could benefit others on the forum. I don't know what he did with the Autel whether he bought it or actually swapped or tried to swap the battery as I haven't heard any news either.

So here is, based on the list he posted above my replies to him. I hope that helps and please in the future keep private conversations for items that are private not for stuff that could benefit others.

As I mention in Point 1, I don't have an Autel but a Launch x431.


Hi, as you mention, I don't own an Autel having chosen the Launch x431.

However, I'll try and answer what I can off the top of my head. I'd just like to point out, that questions such as these should not be part of a private chat as others can benefit from this.

I'll thus try and answer in the order you posed them

1) I don't know

2) It's the one that will best work since we can't get any Varta batteries in the US

3) I would put it on a battery maintainer so you don't lose all your presets etc. DO NOT, I repeat, DO NOT try and remove the nut off the battery cables completely. Simply loosen them enough to be able to wiggle them free of the posts. Placing a little Vaseline on the terminals of the new battery will help keep any sulfates off it

4) If you have it on a tender prior to the swap you probably won't need step 4

a) Once you connected the new battery you can disconnect the battery tender if you used it.

5) No idea as it's probably different on the Launch

6) Yes - that part number is for a 2020 Macan S. I assume it is for other models as well but just want to be specific.

a) Enter the data and save however you do that with the Autel

Once you've done that, post this and other comments you may have so others with an Autel can benefit. Good luck.

To answer your question, I did buy the Autel MD808P and am waiting to receive it. Figured I should have it regardless. Next I am going to have my battery tested (drive to Advance Auto Parts or equivalent) to see how it tests. If it is good, I will wait for another guinea pig. If it is close to failing, I will be the sacrificial lamb. So, I am moving forward but cautiously as necessary.

One new addition that I am considering:

While I will be able to do the BMS with the Autel, I think the above part will allow me to keep 12V power during the swap and therefore keep all my settings. So, that is a new discovery for me. Not sure it is a good idea since there isn't a consensus but I am leaning towards it since I don't see a downside.

Clore sells the jump packs. Thats not a coincidence.

Like with PIWIS and everything else you pay for a subscription. Seems the update for a year (after the 2 year free is done) is $399.


I don't know about other analyzers but there are two standout items for the x431.

1) It's wireless, so I don't have to tether the OBD2 connector to a laptop or pad.

2) It covers myriads of vehicles if your garage has more than one vehicle and it's not a Porsche.

Will I need the latest and greatest update after my 2 year? Unless something major is missing, I doubt it.

Front CV joint tend to have minimal play as are the ones which take all the stress as they move constantly, all cars show some wear, if you grab the axle and try to rotate it should not move more than half a mm which is acceptable, more than that is a sign of excessive wear.
unless the play is too much they don't tend to sound.
Which kind of sound are you after? clunking sounds often comes from brake pads if the spring retainers were to replaced when the brake job was done, those springs loose tension which the heating cycles and loose pads can get very noisy.
 
#660 ·
No rotational movement in front CV, just ~2mm in and out as you shake it in the direction of the shaft.

My primary request for this post was to see if anyone else has this movement in the axle. The quest for the clunking sound may be different and I'll look for that outside of this post.
