Hi guys.

First time here for me.

I have bought the Cayenne s and have som trouble with it. The car was standing out side over night in about -5 Celsius. In the morning when I started the car the PSM default whent upp in the display. I tried to restart the car but it did not disappear. When I was driving the car the gear box did not whant to change any gears. Think it's running on 2 or 3 gear all the time. I live in the northern part of Sweden and there are no porche dealers here. So I took the car to the only guy who has the Porche computer. When we connected the computer it says: tiptronic not found. Abs DME control module 1314. 0668 vehicle voltage terminal30. 1315 tiptronic controll module. 1299 gateway.

The mechanic says he can't enter the PSM system and erase the faulty codes. So he has no clue what to do.

The nearest porche dealer is about 1000 km from me, so know the car stands I my garage and I don't know what to do with it. Please, help me if you can

Sorry if my spellings is bad,


Peter from a cold norther part of Sweden

Hi wvicary

I'm not sure what modell this guy has. Will check it today. But he helps Porche and has got his computer from Porsche in Germany. The guy who helped me has the rights to do warranties for Porsche. He is a engine mechanic for Porsche when they drive porche cup I Germany I think. And when he's home he makes service on Porsche and preformens updates on boxers. They are sending engines from Germany to this guy. Be he says that it's easy to remake a an engine instead of electrical problems.

I'm going to call him today. I forgott to write that one code is P0600 as well. What I found on the forum is that it might be the air flow sensor???

I'm going to buy a new batteri, but the one I have less than one year old.

Thanks, get back when I know what computer he is using.

Hi, thanks!

Will check the fuses today so I'm sure! The guy who helped med with the computer has spokend to a Porsche technic he just sad, start by changing the tiptronic module.

What's moste likely the problem when gearbox runs in limp home mode?

Found a guide on the web where you can measure if the box is brokend. My mechanic will do that search in the end of the week.

If any one have had the same problem, please let me know

2 ours drive from me, there is a Porsche development test centre. It's where they test new models that will come to the market in some years. They do the winter testing here. A friend of mine has spokend to them and maybe they could help me. But it's so secret about the new models so I'm not allowed to drive the car in test center my self.

What codes will clear? I assume all except the gateway and PSM? Sometimes when I encounter a low voltage fault with communication errors you need to remove the affected module then re-introduce it to the gateway.

1314 code relates to DME, 1315 code relates to Tiptronic Control Module.

Sounds like these units are not communicating with each other through the CAN bus.

Before spending any money or trying to reprogram, I suggest you physically disconnect, inspect, clean and reconnect the electrical connectors on the DME control and also the Tiptronic Control Module.

After this go ahead and clear messages then try to reprogram.

Good Luck.

Thanks bigbuzuki

Is the DME located under the passenger seat as well? Should I take the power of the battery before removing any cabels from the DME?

I bought at Toyota corolla to drive untill the Porsche is ready again, but after driving the Toyota I really miss my porsche!!!! So I hope I can get her running soon

Cheers Peter

DME is located under the engine hood, extreme right hand side, under the removable grill just down from the windscreen lower edge, near the brake fluid reservoir.

TIptronic module is under the right hand seat.

Battery disconnection is recommended.
