TSB for advanced key and excessive crank time. . .
My 2005 C6 3.2 underwent the upgrade to the MMI about a month ago and all is well, surround mode sticks, new MMI start up screen and no more lawyer screen.
My car has Advanced Key.
Crank times have steadily increased on FIRST start of the day (thus far.)
I called my MMI update guy and he says: "Yep, there are 2 TSB's on cars like yours and ONE of the symptoms is excessive crank times." By the way, the crank timeout is 10 seconds -- I have not ever gone that far. The crank times were, however, getting ever longer.
New software (for the TSB's) applied today.
When I get the paperwork, I will post the TSB info regarding this.
If someone else already knows any more than what I have just written, please post it.
Thanks.

Subject:Engine Starts Hard or Ignition Key Must Be Held in Crank Position for a Long Period of Time
Model(s): A6 2005>2006
A8L, A8 2004>2006
Group: 94
Number: 05-02
Date: Mar. 1, 2005
Condition
Engine starts hard or ignition key must be
held in crank position for a long time.
May be caused by the Access Start Control
Module, -J518-, losing transmission selector
lever position data if the battery has been
disconnected or if Engine Control Module
(ECM) -J623-, has been accessed using a
scan tool and DTC interrogated.
Production
No change.
Service
When vehicle repairs are completed, i.e.
battery reconnected or when the ECM is no
longer accessed with a scan tool:
* The access Start Control Module -J518-
must re-learn the transmission selector lever
positions.
This is accomplished by learning the full
range of travel of the selector lever as follows:
- Switch Ignition ON.
- Place foot on brake pedal.
- Move transmission selector lever from the
park position to the sport position (S) and
back to the park position.
- Switch ignition OFF.
* The ECM has now learned the selector lever
positions.

TSB # - 2010941/3 (96 06 03 Oct. 31, 2006, 2010941/3)
Engine Does Not Start/Intermittent No Start Using Advance Key Start Button, Starts w/ Key & Ignition Switch
96 06 03 Oct. 31, 2006, 2010941/3. Supersedes technical service bulletin Group 96 number 05-01 dated Nov. 14, 2005 due to updated information.
Model
s) A6
Year: 2005 - 2006
VIN Range: 4F_5N_00001 - 4F_6N079103
Vehicle-Specific Equipment: Not Applicable
Customer states that engine does not start or intermittently does not start when Advance Key engine start button is depressed.
Engine will start using ignition key and ignition switch.
Technical Background
May be caused by:
A. - Mechanical issue with the engine start button.
B. - Electrical issue with the engine stop button.
Production Solution
Production (B. only)
Updated access start control unit software.
Service
Perform the following ONLY if Condition is accompanied by a Customer Concern:
A. - Mechanical issue with the engine start button:
Rationale
Engine start button has two detents. Similar to ignition switch, the first detent will activate 15 power. Second detent activates starter.
When depressing engine start button, flow from initial push through to second detent should be smooth; audible clicks should be heard as detents are reached.
In some cases, second detent, starter activation, cannot be achieved due to mechanical tolerances within the switch.
* Interrogate fault memory of access start control unit, address word (05), with VAS 5051/5052.
If no fault is found:
* Check engine start button functionality by observing measuring value block 2, fields 1 and 2, of access start control unit.
If engine start button is found to be non-functional:
*Replace Advance Key engine start / engine stop switch. Refer to Group 96 - Lights, Switches - Interior, Anti-Theft in the Repair Manual for appropriate repair procedure.
If fault code 02764 008 "Button for start/access authorization - incorrect signal" is found in access start control unit:
* Go to "B. - Electrical issue with the engine stop button" below:
B. - Electrical issue with the engine stop button:
Rationale
Engine stop button has two internal micro switches, activated when the button is depressed.
Both micro switches send a signal independently of one another to access start control unit. When access start control unit receives both signals within three seconds, access start control unit disables the engine, as long as vehicle is stationary.
In some instances, the engine stop button may be held down lightly but not in the fully depressed position.
Example:
May be a cell phone resting on the button:
In this case the access start control unit receives only one micro switch signal.
The Access start control unit determines the situation to be implausible. Fault code, 02764 008 "Button for start/access authorization - incorrect signal", is set in access start control unit and engine start button is rendered inoperable.
Software level update 180 for access start control unit changes the three second threshold to thirty seconds. If thirty seconds have passed while engine stop button is lightly depressed,
Fault code, 02764 008 "Button for start/access authorization - incorrect signal" sets in access start control unit.
However, when vehicle is parked and engine stop button is fully depressed to disable engine:
Fault code, 02764 008 "Button for start/access authorization - incorrect signal" will change from an "implausible signal" to a "sporadic signal".
This allows engine start button to function next time engine start button is fully depressed to starter activation detent.
*Check access start control unit software level:
If level is below 180:
*Perform Update Programming (Flashing) procedure of access start control unit using update CD Part No: 4F0 906 961N.
Tip:
DO NOT replace access start control unit.
Update - Programming (Flashing) Procedure:
Tip:
When performing the reflash procedure, All DTCs for all systems are erased. DTCs linked to Guided Fault Finding function tests will be lost. Therefore, always address stored DTCs for Customer concerns unrelated to the reflash procedure first.
Tool Requirements:
VAS5051 or 5052 (with Basis CD V.07.00 and Brand CD V.07.36.00 or higher) with old diagnosis logs erased prior to start.
Update - Programming (Flashing) CD Part No: 4F0 906 961N.
Approved battery charger.
Tip:
The battery must have a minimum no-load charge of 12.5 volts (failure to maintain voltage during update process can lead to control unit failure). Use approved battery charger to maintain battery voltage.
Additional copies of the "Update - Programming" (Flashing) CD (Item No: 4F0 906 961N) may be ordered from the Audi Technical Literature Ordering Center at www.Audi.ddsltd.com, or by calling 1-800-544-8021 from 8:00 a.m. to 8:00 p.m. EST Monday through Friday. This number can be dialed in both the United States and Canada.
*Insert update CD 4F0 906 961N into VAS 5051 / 5052 tester.
*From start up screen, select "Vehicle Self Diagnosis".
*Select Vehicle system "05 access start permission".
*Select the "Updating - Programming" (arrow).
*Follow instructions on VAS 5051 / 5052 tester.
Old software version will be erased and version 180 will be installed.
Fault memory of the other control units will be erased.
An ignition OFF / ON cycle will be required when prompted. However, do not cycle the ignition while the software is loading.
If you experience any problems, please reference the file under //Manual/GB.pdf on the update CD (insert CD into CD-ROM drive of any Computer) or contact the Audi Dealer Technician's Helpline at (800) 388-2834.
