Should I be worried about purchasing an 05 Cayenne turbo that's been flashed?

It only has 25,000 miles but it's out of warranty.

The car looks clean in person, has a clean carfax, and I would take it for a PPI before I make any final decisions.

That being said, it's been flashed. If the vehicle did pass the PPI, would it be easier on the car from that point on to "unflash" the ecu or has the "damage" already been done?

I know a lot of you guys roll around with flashed cars all day long with no problems, but I have heard some horror stories. Im just looking for a comfortable 2nd car to compliment the 911 turbo. I don't need the Cayenne to be flashed or to have more problems than neccessary.

I was hoping to hear from experience, opinions welcome.

any porsche dealer or independant specialist can return the ECU back to " normal" for you, as its only a written program, but you might find its a " plug and play" type of "chip" if so just unplug it...job done.

to be honist most flashes (generic re-maps) are safe and i wouldnt worry, they can (in my case) drasticly improve the MPG.
so you might be undoing some good work, live with it for a while, and then see how she is, you always have the option of putting back to normal whenever you wish, with no "damage or issues"
good luck.

putting back the stock ECU flash is like throwing $1500 away. Not to mention the good mileage in the long run..

I have a CTT 04, bought it 3 years ago with 28k miles, put a Fabspeed chip and love it, I also have the 996TT 04 cab., its hard to go from the 996tt to the ctt, the chip makes it alot more fun, practical and there only when you really need or want it. the CTT has just over 78k miles and other than normal wear and tear I haven't had any problems what so ever, and I do drive it hard. I love both, and would do it all over again.

the flash is a DTE flash, and it's lowered using the rinspeed lowering module. Does anyone have any experience with these products?

just remember when you flash the ecu and bring it in to the dealer for service (which im pretty sure the previous owner did) porsche records the ecu info and directly sends it in to (hq, or the main office or something) and they see if the ecu has any changes. if so, anything thats related to that issue (ecu) and something happens; your warranty will be voided. if its a plug and play, then the dealers really wont hassel you, if they do, just unplug and it should be fine. verified from my local dealer. hope this helps.

all the flash does is to perfect the generic fuel map and
a few other things to acheive a better more effecient use of fuel.

chris, i asked a friend of mine (mark) who is the service manager at guildford porsche (OPC) in surrey and he has never heard of this?
he said the data would not be read unl;ess they were specifically looking for it under the EMS (or similar) he said nothing except service data is recorded.
i also asked at paragon (major independant porsche service centre) and they said its almost impossible to detect a "flashed ecu" and that porsche do not hold details of every ecu, that would be a logistical nightmare.
as every ecu is self learning they all hold different data.
i doubt its different in the States.

kind regards
david.

david,

i could defintly go into alot of detail about this subject due to the fact that i spoke with my service manager here in the states for about an hr about getting an ecu upgrade when i was getting my gts serviced but i dont have the time. all im trying to say is that people should check with thier dealer before jumping the gun to flash the ecu. if your local dealer says it will void your warranty, putting aside your relationship with them, the probabilty would be that they will void your warranty. so why risk it? and i guess it does differ from dealer to dealer or they are yanking my chain.

You are missing the point, no two ECUs have the same data even if the fuel map is the same...VIN number is recorded here together with immo etc..

Porsche cannot prove if a map has been altered.

i understand the info recorded on the ecu is unique (nobody drives the same). but the perameter (rpm range, turbo boost, etc) which have been set from the factory are all the same for the different models right? so if the perameters have been changed for ex. for a turbo to get more boost wont they be able to a run a diagnostic to see if it has been altered; say if you blown a turbo and bring it in to the dealer and you try to get it fixed through warranty. they could void it right?

-chris
im not saying that im right, just going with the info on hand, and trying to figure out if an ecu upgrade is worth it.
