DME Control Unit: Fault Code P1095 (MAF Sensor) (24110)
Tools
Model year:
as of 2009 up to 2010
Vehicle Type:
Boxster (987)
Cayman
Equipment:
2.9liter engine
Porsche Doppelkupplung (PDK) (I250)
Concerns:
DME control unit,
Hotfilm mass air flow sensor (referred to below as "MAF sensor").
Information:
Fault code P1095 in DME control unit (Check Engine warning light activated).
Fault code U0401 in PDK control unit ('Gearbox emergency operation' appears in white text in the instrument cluster).
Due to a software error in the DME control unit, a fault is detected on the MAF sensor in certain environmental and operating conditions
although the MAF sensor is OK. As a result of this software error, fault code P1095 is stored in the DME control unit or fault code U0401
is stored in the PDK transmission.
Since March 13, 2010, the software error has been corrected using a modified DME data record.2010 Porsche Boxster (987) F62.9L

Action Required:
In the event of a complaint relating to vehicles manufactured before the date of introduction, check the data version of the DME control
unit.
Action required for vehicles manufactured after the date of introduction: see > Procedure" section > 2.
To determine the DME data version:
Using the PIWIS Tester 9718, select > DME control unit > Identification to find out the part number of the DME control unit.
Boxster
If the part number is 987.618.623.30 or lower, see > "Procedure" section> 1
If the part number is 987.618.623.31 or higher, see > "Procedure" section > 2
Cayman
If the part number is 987.618.621.30 or lower, see > "Procedure" section > 1
If the part number is 987.618.621.31 or higher, see > Procedure" section> 2
Information
Concerns: Engine replacement.
If the engine was replaced in the vehicle, the model year of the new engine is a decisive factor in selecting the DME data record to be
programmed. If in doubt, read off the model year from the engine number. See > Workshop Manual 1X00IN Engine numbers and >
'Driver's Manual Vehicle Identification, Technical Data'.
Work Procedure:
1. Part number is 987.618.623.30 or 987.618.621.30 or lower:
The data version is not uptodate.
Use the PIWIS Tester and test software version 27.000 (or higher) to reprogram the DME control unit.
See 247019 Removing and installing DME control unit section on "Programming".
Once you have worked through any fault codes that are still present, erase the fault memory.
End of remedial action.
2. Part number is 987.618.623.31 or 987.618.621.31 or higher:
The data version is uptodate. Do not replace the MAF sensor yet.
Information
Since the problem occurred on a vehicle after the specified date of introduction and/or after programming the DME control unit: >
Correct the fault using the PIWIS Tester in accordance with Guided Fault Finding".
End of remedial action.
Working Time:
24702553: Programming DME control unit; Labor time 40 ZE
