hi guys,

i need help from those in the know!

I just bought a 2003 cayenne. It has so far after 24 hours 2 big problems from what i can tell....

1) clicking noise when turning either left or right, also a slight humming sound from the front when traveling over 30mph

2) auto gearbox dosent shift to 1st gear when coming to a stop. it changes to 2nd and thats the lowes it goes!

you can select 1st form the gear controls on the wheel, but the semi-auto stick shift dosent seem to work.

what id like to know is your opinion on the probable cause of the above issues and also an estimated cost.

im in the northwest of england, so if anyone knows somewhere good who are 'cheap' but know what they are doing that would be a bonus.

cheers

1 is most likely the lower control arms which need new bearings at this age the humming needs more of a definition by you, where, what frequency

2 It starts in second for fuel economy and in first when cold to heat the cats up as fast as possible to get emissions under control

Dont know anyone over there but there will be someone, look for german car specialists

Having gone from an S with lag to a TT I now realize the S power curve did not match the transmission. When you get to 500, in sport, there is zero lag

beginning to sound like fuel pumps beginning to fail to me, the car is the right age for that to happen

when you say "went blank" what exactly do you mean?

Mine was traded 2 weeks after the first one went, only time in 130K miles I had a breakdown

1- how old is battery ?

2 - magnets on shifter can fall off but manual would work since its sequential

3 - any errors codes ?

I was told by dealer that pumps should be replaced in pairs but most people don't due to cost

Something is very wrong then

On an S 14 and higher should be expected unless your towing

Go do a manual check. filler her up, note the mileage and then on next fill do the math, only way to be sure

Thanks but I am not familiar with the V6, the codes 0011, I would do an oil change and maybe flush it. 0441, I would check the gas cap seal first just to make sure

How old is your battery ?

2227

1 Check EVAP canister
purge valve
♦ Remove valve
♦ Check whether the
valve closes fully
Step 2 Replace EVAP canister purge
valve
→ End
2 Check mass air
flow sensors 1 and
2
♦ Connect the
173 universal test
box, 105-pole and
the 173-1 adapter
cable, DME 7.1.1
♦ Switch on the ignition
Measure signal voltage
between DME control
module connector:
♦ A, pin 29 and ground
♦ B, pin 109 and
ground
Voltage between 0.9 V and
1.1 V
Step 3
Replace faulty mass air flow
sensor
→ End
3 Check fuel pressure, volume supply of fuel
pump and injection valve (mechanically)
Continue troubleshooting in Engine Manual (Group 1) and
Fuel Exhaust Engine Electrics Manual (Group 2)
→ End

The last one is my bet, 04 at this age, one of the fuel pumps could be starting to go, mine went at 128K and others have gone as low as 50K

Hope this helps

the diy is not for a v6 engine sorry

you got that right

If you see the leaks you could be to late, secondary damage from spilt coolant somewhat more dangerous than the failing pipes

You need to get the actual error codes from the computer to determine what has failed, do you have access to a Durametric ?

How old is the battery ?

The PCM in 955 is very different from the PCM in 957, although they look very similar. The rest of your description is very typical of a battery going bad tho, I would change that before you do anything else

vehicle is drivable unless CEL is flashing

Replace both batteries if you have 2 but leave them both disconnected at the same time for a while then connect them up and try it. Make sure you pay careful attention to the ground (earth) cables which may have some corrosion at the body, clean that all up first

you should be good then

You sure its an 08 ? the pipes are different on the 08 although there is another small coolant is but nothing major. seeing nothing on the site

The symptom you describe would most likely be described by Porsche as either non existent or a feature, either way thank your lucky stars you tranny is not an 04 because after mine was changed to an 05 it was much better but not fixed

The are a few factors causing this, the e-gas adaptation which maps your driving habits, the transmission mapping which is bizarre at times

I also have a very personal opinion that the S does not have the power to use the mapping provided in the transmission

You adapt to it or you bail, there are part time fixes but nothing permanent sorry

how long have you had it ?

Neither do a good job streaming over BT. I use Mobridge and also had that when I had the 04. iPods work, great sound clunky interface, the BT works now only if you have the phone buttons on the PCM.

Having said that once you get used to the interface the music sounds good thru the Fiber connection to the Bose. The BT sounds good to people I call with my iPhone.

Audi Glass Packs maybe

suprises, more like shocks lol
