Gus, I'd wager that Suncoast has them in stock or can get them quickly.

Good point! I didn't think I'd have to go to Suncoast to get sensors that worked, since they're a straightforward, common part, but since there seems to be an issue, they're definitely going to have the right part.

No-name TMPS sensors that work with older Porsches: $40 each.
The Huf supposedly OEM sensors I did buy: $80 each.
Suncoast's Sensors: $115 + $25 extra for the stems = $140 each.

Quite the price discrepancy. I imagine the dealership would charge at least that much, though. I guess I'll call them tomorrow.

 

so i saw 110oct leaded gas this morning ( at a pump) i was actually tempted to use it any reason why i cant?

 

There is no real benefit to using a higher octane fuel than you need. Octane mostly reflects ability to take high compression without detonating, not energy delivery.

As to whether you can use it, that depends on what additives are bringing the octane that high. 100 is the nominal limit for pure gasoline. Not that pump gas is ever simple, it's always a complex mixture.

If it was actual leaded, that's likely to damage your engine.

 

For what it's worth, this worked. I ordered the sensors from Suncoast, they showed up this weekend, I had NTB swap the new sensors for the old. The car started reading the new sensors immediately.

Both sets of sensors were 433 MHz, so it's clearly not something simple like the wrong frequency. Porsche clearly changed the electronic handshaking with the 2014 and later cars. You can't get aftermarket TPMS sensors for 2014-2015 yet, only the actual Porsche parts will work.

This was expensive, but from what I've read, I still ended up saving about $400 over going to the dealership. That is, I've seen several sources claiming Porsche dealerships want $1000 to install new sensors, $500 over the cost of the parts.

 

This is disappointing to hear. I assume the same will hold true for the 2015 Cayenne. I just bought a set of 2011 20" Cayenne RS Spyder wheels that I mounted with snow tires. Assumed it would work, as both are 433mhz as you stated. I guess I will find out once my car arrives in Jan.

Assume there is no way to check it they "talk" to the car unless I take off the factor wheels, throw on my 2011s and drive a few miles? Would be nice not to have to jack up the rig and change wheels twice to confirm.

 

Correct, the only way to check is to mount the wheels. Communication is very short range, since the car needs to identify sensors on a per-wheel basis.

Since the car is arriving in January, it's likely you'll want to mount the wheels with the snow tires immediately. If the sensors don't register, you'll have to do what I did - buy new sensors and replace the old ones, which involves removing the tires and then remounting them.

 

The operative word here being "2010." From my research, it appears that model doesn't matter - Cayenne, Cayman, Panamera, and 911 sensors for any given year are the same, though it's still not clear to me whether some are 315 MHz or not. The year matters, because they periodically revise the sensors.

The sensors I bought from Titan TPMS would work just fine in a 2011-2013 Panamera, but not in a 2014-2015.

 

Called my dealer... looks like I am SOL. The Cayenne TPMS also changed for 2015. New part number is 5Q0907275 or 5Q0907275A depending on VIN.

 

I'm having a 9500 CI installed today but im curious which battery it will run off it..

 

This Christmas trip brought my total mileage over 2000 for the first time. 2000 miles in 4 months isn't much by most people's standards, but I generally drove the Supra 2000 miles in a year.

On the Vienna-New York leg back I had a malfunction alert. The car popped up a red warning "Coolant low, stop driving immediately." I came to a stop, and the warning went away. Engine and oil temperatures were still dead cold because I'd been driving on electric. I kept expecting another warning but it never came back.

Reading about this online, I gather this probably means the coolant is indeed very low, but not quite enough to expose the sensor all the time. The car was in a parking garage in New York for 3 days, and I expected to see the warning again when starting the engine cold, but I didn't.

Low coolant probably means a leak somewhere. That's distressing, since I'm used to cars which don't have any mechanical trouble for the first 100,000 miles. I expect very high reliablity if I buy a car for $100k.

At least the oil level is still at maximum. I've read burning oil is somewhat common in Porsche engines. The Panamera S E Hybrid's engine is technically an Audi part, of course.

 

actually something like that happen to me as well .. I was getting off the highway and mine came on as well but as soon as i was back on a straghtaway it went off .. didnt really pay it any mind. but now i wonder

 

When I did check the coolant, it was low. Below the minimum fill line. However, there was still coolant visible in the plastic reservoir / expansion tank, so it wasn't drastically low, unlike some of the stories I read.

I'd say that if you got that warning, you should definitely look.

 

i wanted to replace the wiper fluid with something of a deicer anyway so i was going to do them togather

 

so what i found out is that there are two types of coolant .. one for your engine and one for the battery.. when the low coolant light stays solid its the engine when it flashes its the battery .. turned out my battery coolant was low
