so I changed myself the supercharger belt. It takes 3 minutes. Go rent the long wrench at autozone (loan) or... You have so much room between the belt and the fan that you don`t have to remove anything. I am a beginner...so it was piece of cake

 

 

Does anyone have any experience with AC service on the Panamera S-E Hybrid? I'm getting an intermittent hissing sound with the AC is switched on and think it's due to low refrigerant. In the past, with non-hybrid vehicles, I would just top off the system with a 134a recharge kit from the local automotive shop. With the hybrids using electric compressors instead of belt driven compressors we can't use the typical recharge kits because they contain PAG oil which will contaminate our systems which I believe need POE oil. I got found the below specs on the system, but under the OE compression oil type it lists "NA".

From what I've read, we should be ok to recharge with "pure" 134a (without oil or stop leak additives). The ports are easily accessible so this should be an easy DIY with the right refrigerant. There is a product out there for 134a for hybrids, but i'm cautious about these universal products as I have a feeling they're geared towards Prius and doesn't list any specifics.



Does anyone have any additional information or experience with this system. Dealer quoted $400 for recharge, but I can do for $20 if pure 134a (no oil/additives) will not harm the system. I don't want to pay for a recharge if I have a leak, which I'm guessing I do. I'd rather spend $20 to verify the leak and pay the dealer to fix it.

 

blakey,

Newbie question...How would you verify a leak?

 

Would you be kindly to show us how to do it? We would appreciate for your contribution here.
Many Thanks

 

I mean how to change supercharger belt.

 

Usually the leaks come from the condenser (radiator in the front near the air filter), but I would need to verify. There are many companies that offer 134a with a UV dye in them that will highlight the leak if present under a black light. This goes back to my original question though, that I'm not sure if I can use one of these dyed products either because of system contamination. To my understanding, our oil goes through the winding of the electric motor powering the condenser. Hybrid oil is non-conductive so in event of a short in the motor no current is transferred. If the oil would be "contaminated" with another substance (oil or dye) that is conductive then if there were to be a short in the system, unlikely but possible, some of that current could be transferred to the housing and create a shock hazard.

Long story short, I think any of the 134a coolants will work and not harm the system, but create a safety hazard in the event of a short. Again, that's just my understanding from what I've been able to find. That said, I don't want to contaminate the system and find out the expensive way I'm wrong.

 

Hi,
Request please.
Can you take a photo of the conventional battery?
I need to see how the battery is attached by the harness that keeps it in place.
Please
Thank you

 

 

Hi,
Who has changed their conventional battery?
Mine is due.
Porsche will install a 75AH instead of a 92AH EVEN IF you had with your VIN the part #958-611-092-21 will show but they will install a 958-611-075-21
The Varta 92AH is too big to fit in!!!
My best bet at this time, the Duracell Platinum Group Size 94R (H7). This is the only close to the specs or the insterstate MTX...

Any thoughts?
Appreciated

 

Thank You

 

The supercharger belt is so easy to change. Get the special wrench that you can rent at autopart store. Look for a good video youtube that shows how to swap it. so easy to do. and you have plenty of room to do it from the above. 5 minutes job.
I am serious

 

BATTERY
I replaced the original one by a Duracell AGM platinum Group Size 94R (H7)
AND USED
in order to save the memory.
Unscrew the 2 bolts that secure the battery. unclip the vent hose ( right side. Super Easy). Done
It took me 15 minutes to swap it.
COST $200
Dealership Cost $880

 

I haven't had to do this yet, but know the time will come within the next year or two...Thank you Maxime75us!

 

Thank you Maxime75us for sharing the article. I am sure I will do battery replacement next few years, I have 2 2016 pan4 and pan-hybrid. Why do you need the ? you connect it from new battery to Porsche ODB II port. I don't get it ...
