Cayenne 2006 Starting Problem

[mbenje]

Hi all, I'm new here. I have 2006 Cayenne V6 . My car doesn't start. I used scan tool Launch X431. And retreived codes from DME : P2632-Fuel pump "B" control circuit open, P0700- Transmission Control System (MIL request). It doesn't start. Only cranks. If pull out fuel pump relay (404)and make bridge between terminals 87 and 30 (3,5) it starts rigth away. But transmission is in limp mode. What is problem ? Is there any person who faced like this problem? In my country dont have Porsche dealer. I'm in Mongolia Ulaanbaatar. So any advice will be helpfull.

Thanks,

P2632 Fuel Pump Relay 1 Output Stage - Open Circuit / Below Limit / Above Limit

Possible cause of fault

- Fuse FE13 faulty

- Fuel pump primary relay faulty

- Open circuit

- Short circuit to B+

- Short circuit to ground

- Vehicle electrical system control module faulty

- DME control module faulty

P0700 CE Light on Due to Transmission Fault - (Signal Implausible))

Possible fault cause

- Fault memory entry in Tiptronic control module due to transmission fault

You are likely going to need a PIWIS tester to read the Tiptronic fault(s) and reset the Tiptronic controller.

Very cool you have a Cayenne in Mongolia! I'm sure you 'll have your problems sorted out soon and you'll be back on the roads and trails. Take care.

Thanks Loren,

I will check a fuse FE13 . Also I have to buy PIWIS . But original one is too expensive for me. In China's market I found copy one (I think illegal copy)for 3000$ US. Is there anyone who uses china made PIWIS ? How safe is it? How it works: same as original one or missing some functions ? I have no experience. Closest Porsche dealer is Beijing China. So I need to solve problem by myself but without PIWIS it's nonpossible. In the road of Mongolia several Porsches. If DME control module or Vehicle Electrical System Control Module are faulty do I need to change module ? Also should I programm new control module or it fits directly ? Can I use used module? I have so many questions. Thanks for you all of guys. It is wonderfull web site . Thanks again.

Benje.

Why not buy the Durmatric software?

[mbenje]

If I buy Durametric , is this deals with DME actual values and actuations , modifucations(when I exchange DME control module or electric control module )?

[Loren]

If you plan on changing the DME and need to completely copy the program from one to another - you can only do that with a PIWIS tester.

[mbenje]

Is Durametric deals with the tiptronic controllers : erease fault codes? Rigth now I'm not sure where problem lyes : in bad situation i'm planning to change DME or electrical control module.

Regarding diagnostic tools: I found one diagnostic tool which name is autologic(made in GB). They said autologic porsche diagnostic tool is dealer level . Anyone who used this tool????
