My 04 cayenne s doesn't want to start. Never ever had an issue with this. Car cranks like its about to start but nothing. First gave me 4x4 error then low oil pressure error and finally abs failure. I haven't changed oil in about a year. The oil is not low but pretty dark and could use a oil change. Coolant pipe upgrade was done last year with only issue after upgrade has been car temp gauge gets kinda hot but doesn't completely over heat. Please any help ??????? PLEASE !!!

 

battery issue? I've heard the cayenne does a lot of weird things when the battery starts to fail. does it start clicking after a few cranks? maybe fuel pumps?

 

So I tried again and gave it some gas and it turned but was shaky also ALOT of white smoke came out of exhaust. I turned it off after about 10 seconds. Didn't see any errors just lots of smoke that smelled like fumes. I'm too scared to try to turn it on again. What else can it be ??? Thanks for ur help. I really appreciate it.

 

sounds like a battery issue, not enough crank amps to crank the engine fast enough. it will start to click after it fails. hopefully that's it.

 

Don't think it's battery since it turned on just now but was shaky and lots of smoke from exhaust.

 

I would check the battery too.

 

how long has it been since you last started it? so it's idling rough and black smoke? if black then that's rich condition, shouldn't really do that though, but could have some residual fuel in the cylinders if you kept cranking with no ignition (firing up). I'd still have the battery tested just to make sure.

 

Looking at the battery is a good idea, but it also sounds like a fuel pump problem to me as well...

 

Fouled plugs, bad coils, fuel pump(s), battery, fuel-filter, fuel pressure regulator, camshaft sensor(s). That's the items I'd guess* and in the order of probability.

* = Since the vehicle has undoubtably stored some fault codes in the engine CPU, it might behoove you to get them read and see what the truck thinks is wrong with itself. They're not always directly applicable, but if you post the codes here chances are someone might recognize them. Randomly throwing parts at the beast based on some Interwebz guesses by other people trying to be helpful can get awfully expensive awfully fast, making the price of a DuraMetric seem cheap. Even basic OBD-II reader may give you some clues, but a dedicated Porsche specific diagnostics tool is really the way to go. It will cost WAY WAY less then taking the truck to the dealer even once.

As far as it never doing it before - most things DO work until they break, then they're broken. It's how life works.

 

Good list of where to start. If coils are weak and plugs are fouled then a rough idle and smoking could definitely pop up.

A little off topic but:
Good advice! I'm picking up a durametric Tool next week! Which one though? The enthusiat or pro? What about the coding options? Maybe some other members are curious about this too?

 

I have the enthusiasts version. The Pro is enough more $$, that I don't think the value is there for a single owner. Of course if you could get your local chapter of the PCA to buy it (perhaps as a subscription sort of buy-in by members), then the Pro would be the way to go..

 

Thanks a lot guys !!!!!
I use the car all the time but it was about 4 days that I didnt turn when this happened. It did turn on once while giving it a lot of gas. I haven't tried to turn it on again. It threw white smoke that smelled like fumes and gasoline. I turned it off after 10 seconds. I'm going to take it to Porsche specialist next week. Hopefully it's something small. I hope !!!!
Thank god 4 my 97 Vw Jetta. Best $1000 ever spent !!!

 

Don't be insulted, is she parked on an incline or is the fuel low? Do you use a decent brand and octane?... The symptoms sound more like fuel pumps... I have an acquaintance who has an 04 cS and that's verbatim what it did. Problem originated from dopey driving the car until the fuel range was near empty < than 50 miles range, truth be told she asked how can the pumps burn if I have 10 miles to go....

 

The truck is at half a tank and in the garage. 90% of time I put premium but I do always wait for last possible second to refill due to Chicago gas prices being ridiculous an waiting till I go 2 suburbs. I always wait till range shows a straight line ( zero)
Thanks

 

btw, you should not need to "pump" the gas on these cars, lol. Technically you're really not giving it more fuel, in fact in some cases you cause the engine to be lean, which would cause the engine to have issues starting. Maybe it compensated for the lean condition it saw and over fueled. The IAC, idle air control valve typically takes care of most of the air needed at idle and there is preset fueling tables for startup based on air temp, load, coolant temp, etc. So basically don't touch the pedal when you start it, it doesn't need that.
