Service

This TSB replaces Pending Service Solution (PSS) 2072399:93 PSS: Q8 e-tron - Release AC connector option not shown in MMI.

The software for the high-voltage battery charging unit (00C6) must be updated on this vehicle. Explain to the customer that various control units must be reconfigured after the software update to ensure that they function correctly in conjunction with other control units in the vehicle. Components which have been retrofitted in the vehicle but have not been entered in the vehicle equipment list via feedback documentation (version compare) to the SVM may not function correctly after the configuration process. Ask the customer whether they have had non-genuine components retrofitted on the vehicle or modifications carried out by third parties (e.g. tuning) or are aware of any such retrofits or modifications. Inform the customer that, if non-genuine retrofits or modifications have been carried out on the vehicle by third parties, neither AUDI AG nor your own company will accept liability for any damage that may be caused by updating the software, or by failing to do so. Make a note to this effect on the order before it is signed by the customer. Include this information in the customer file.

 

Try to reproduce the customer complaint (based on the description/cause of the issue), so that it can be clearly assigned to this TSB. The following repair must only be carried out if all the criteria (model/type, chassis number, engine/motor and gearbox code, PR number(s), part number, software version, code etc.) apply exactly. Otherwise, this solution will not eliminate the problem and repeat repairs may be necessary. In such a case, we may reject the warranty claim and charge back the cost of the parts.

Applies to vehicles with high-voltage components:

A software update must be performed on this vehicle. Please observe the information and instructions under “Customer information”.

Please flash the control unit for high-voltage battery charging unit (00C6) using the SVM code.

To enter the SVM code, use “Flash” mode on the ODIS tester.

NOTE:This must be done in 2 stages:

For stage 1 the SVM code required is C6A015.

Follow the instructions on the tester.

Now perform a terminal 15 reset for 2 minutes.

For stage 2 the SVM code required is C6B015.

Follow the instructions on the tester.

Note:If event memory entry P31E200 is logged as static in diagnostic address 00C6, proceed as follows:

Charge the vehicle using AC power for 2 minutes. The event memory entry is then logged as intermittent and must be erased.

 

If you require any assistance when working with the diagnostic tester, please refer to TSB 2011732:00 Software Version Management (SVM), operating instructions. The procedure for contacting product support can also be found in this TSB.
