I am proud owner of a 2009 997.2 C4S with PDK and have had her about a year. She is fully serviced by PMD and currently at 68K miles.
About 3 weeks ago we were driving steadily along and we received the "Transmission Fault - Transmission emergency run" warning light, and the gearbox went into limp mode.
I got her home, turned off, turned back on again and all seemed well.
Then about a week later, the same happened again and after taking a look, finding the low voltage as a possible cause given the non-daily usage. Fully charged battery, and again intermittently the warning kicks in.
I have now got a ODB2 device and Torque and have found the following error codes:
Current Fault Log
------------------
ECU reports no current faults
Pending Fault Log
------------------
ECU reports no pending faults
Historic Fault Log
------------------
ECU reports no historic faults
Other discovered fault codes
(possibly pending, current or manufacturer specific)
----------------------------------------------------
P2314: Ignition Coil E Secondary Circuit
P0355: Ignition Coil "E" Primary/Secondary Circuit
B2AAA: Unknown code - More information may be available on the web
End of report.
Having looked I cant find the breakdown of the Porsche error codes, and I think im now coming to the end of my self diagnosis phase!
She is booked in at Leicester (UK) end of the week, where she has just had a full service. I had mentioned it to them, so cant claim their service is a probable factor
Any ideas guys? I also have her booked in at Motawork for a gearbox oil change and filter week after next, but if I can get any other ideas before spending yet more money at the stealers, that would be welcome!
Hi - yes I had read that and having checked, its an aftermarket battery. I had fully charged it over a couple of nights and it has the charge control light showing as green:
Not sure what the spec should be - but it seems to be ok (and took two days of charging!)
craigieh,
What ended up happening on this issue? I have the same fault appearing on mine. I also have a Check Engine light that comes on 5 seconds after the Transmission message and one cylinder drops out.

Probably not what anyone wants to hear but this sounds almost identical to what happened to the PDK in my -09 C4S. Had the "Transmission emergency run" scenario twice. Turned the car off and all was back to normal when restarted. Third time it happened killed it. Flatbed to the dealer where the PDK was replaced under warranty. Billed at $14,000. Problem was diagnosed as software related.

Hi,
Sorry about the misfortunes you are having! I plugged the codes in to my database to provide you with the code descriptions, and maybe offering some insight.
P2314
Diagnosis Information - DME (DFI)
Bar ignition module on cylinder 5 - SoftShutDown
NOTE:
- The bar ignition module cannot be tested as it is an active component. If a faulty bar ignition module is diagnosed, the connection to the engine ground must be checked before replacing the module as otherwise a faulty engine ground connection will damage the new bar ignition module.
- If both a driver fault and [SoftShutDown] are entered, the driver fault is the cause.
- If only [SoftShutDown] is entered, excessive coil charging time is the cause.
Diagnostic conditions
- Battery positive voltage between 10 V and 16 V
- Time after engine starts > 2 seconds
- Engine temperature > -30 °C (-22 °F)
- No driver fault stored
Possible fault causes
- Short circuit to B+
- Short circuit to ground
- Open circuit
- Fuse D7 faulty
- Bar ignition module faulty
P0355
Diagnosis Information - DME (DFI)
Bar ignition module, cylinder 5
NOTE:
- The bar ignition module cannot be tested as it is an active component. If a faulty bar ignition module is diagnosed, the connection to the engine ground must be checked before replacing the module as otherwise a faulty engine ground connection will damage the new bar ignition module.
Diagnostic conditions
- Battery positive voltage between 10 V and 16 V
- Time after engine starts > 2 seconds
- Engine temperature > -30 °C (-22 °F)
Possible fault causes
- Short circuit to B+
- Short circuit to ground
- Open circuit
- Fuse D7 faulty
- Bar ignition module faulty
As far "B2AAA" I will have to check on PIWIS TSI tomorrow at the office if you would like. Sounds like the DME could be giving issues but is hard to diagnose without having the car in person to run a series of test on it.
