I changed now both MAF Sensors. if the Engine is cold and I start the engine the engine goes out after 5 seconds. if I start and play with the acceleration to keep it going  and the engine get a little warm the engine make no trouble by starting. I delete the codes and drove now 50 miles but  both Turbos don't kick in .I stopped and the engine starts with idle up and down between 500-1000rpm and shut down. if I start the engine and accelerate the engine a couple times to 3500 rpm the idle problem stops and the engine stay on. 

2 codes are coming everytime back P1095 and P0299.

Please help

I have a new problem with the 2006 Cayenne Turbo 4.5v8

the car lose a lot of power and the rpm is going up and down. I read it out and got follow codes

Question where is the G336 Sensor? The idle problem is coming from the leak I think. will check all at Tuesday. someone know how to teach the angle sensor with VCDS?

After a driving of 25 miles I parked the 2006 Cayenne 4.5 Turbo. on the next morning the Engine idle up and down. I was thinking about a vacuum leak and checked all but I didn't find nothing. If I start with cold engine and idle  Problem the Car and put the gear in D and drive a short distance the Engine runs smooth again. I hooked up VCDS and got follow codes

The only what cud cause the Problem what I see is the G336 Valve. does anyone know where this Valve is located or is it the TPS direct and the Butterfly?

ok will do that. But now I have the next Problem. the rpm goes up and down and sometimes stall the Engine. I checked all vacuum hoses but nothing. I read out the ECU and get follow codes. P1095, P2178, P2180.

by the P1095 I get different solutions changing Mass air flow sensor or that

where is that Valve?

I drove now 25 miles with the Car and  sometimes you hear how the ABS Module starts working and the PSM starts flashing. the same I have  now with the other Porsche too

the oil monitoring failure is out but the PSM stay on. if I drive the Car sometimes went the PSM light off but after I brake down it comes back on.

checked the fuse there is not one in. will by tomorrow a new fuse and try it again

got the cable from ross tech

Thanks a lot the AC works fine. now I have only to find the problem why the Cluster show oil level monitoring and psm failure

one problem fixed an other is there. the Ac stop working. I checked the cabel on the Compressor and I don't have there 12V. all Fuses in the right panel fusebox #23 and #25 are ok.

do anyone know where the relays are?

which fuse I have to pull?

i have VCDS 16.8 and I don't get response from the controller module to get to the adjustment. I drove the Porsche first it was a hopping bunny because the front suspension was complete down but after driving it pumps up. after 2 days parking the front goes down again.

will do it tomorrow. I can ready out the Engine under a 2006 Touareg but the rest is not working. the struts in the front now up after 5 miles driving but it is not adjustable.

I drove the Porsche now but I still get the message oil level monitoring failure and PSM failure

thanks to loren he send me a description. to set the cam timing is very easy and goes  fast

is a 2006 Cayenne 4.5 V8

it tell me always 'no response from Controller

That is by the Porsche not working. if I go on 34 then he starts with searching and the message comes "no response from Controler" by the other Cayenne which I have I can read out nearly everything.

ok will drive tomorrow the car and will send a update.

the suspension was 50% working it went up and goes 1 level more up and down. the car was parking 3 weeks and the Battery was dead. I put a smaller battery in of a chevy s10 but the suspension don't raise up in the front. I have vcds where I have to go to see what is going on?

I have here a 2006 Porsche Cayenne 4.5V8. The car get new Air struts in the front and regulator Valve but the front Struts stay down. in the Cluster comes the message not permission. had someone an idea how to fix that?

I have a 2006 Porsche Cayenne 4.5 V8 Turbo.in the Cluster comes now the Message oil level monitoring failure and PSM Failure. I replaced the Level sensor but I still have the Message. what means PSM failure and had someone an idea how to fix it?

after checking the timing again and blocking the Cranskshaft I saw that the timing was off from the exhaust Camshaft Bank 1 after I set the timing new and bend the tap back in position. engine runs smooth

I check today the timing and both cams are out 1 tooth. still searching a timing diagram

and a new day starts. I checked the timing today and saw that both cams are 1 tooth out.

if the tabs are broke then you have misfire and rough idle but if it broke off then is the engine stalling.
