Hello guys!

I've used my 2011 Q7 TDI to tow a 5800 lbs travel trailer regularly for three years, with no issues. Last year, I deleted the emissions gear and installed a Malone Stage 2 tune. On my first towing trip (200 miles each way) since the delete, 1h into towing at 72 MPH in manual mode, the cruise dropped off and the trans temps began to climb and I was down to ~4 gears. A key cycle restores normal transmission function....until the issue comes up again. The issue has continued, but only happens when towing.

I've attached a full vehicle scan from the end of the towing season last year and have chronicled my troubles on Audiworld. I've talked to Malone and they haven't had any other customers with similar issues. The thing that is confusing to me is that the 0C8 transmission supposedly has a captive clutch (i.e always engaged) in the torque convertor, so the error of "Torque Convertor Clutch Stuck OFF / No Power being transferred" doesn't make much sense.

Peter from Ross Tech provided the following information:

As per the Official Factory Repair Manuals, the fault code P0741 will
set when, "The Engine RPM vs. Input RPM is greater that 100 RPM for 2.0
seconds." This could be a concern with the [N443-Pressure Control Valve
7], wiring or connection concerns, internal transmission concerns, etc.
(see wiki page linked below).

Also these conditions need to exist to set the fault(as per repair
manuals):
- Engine speed greater than 400 RPM and less than 4,000 RPM
- Shift lever is in [D] or
- Estimated engine torque greater than or equal to 0 Nm
- Vehicle is moving forward
- [N443] target current > 1,000.0 mA
- Model oil temp. >= 20° C

We have a Ross-Tech wiki page for this fault code that lists some
'Possible Causes and Possible Solutions'.

P0741-Torque Converter Clutch: Stuck OFF / No Power being transferred
http://wiki.ross-tech.com/wiki/index.php/17125/P0741/001857

We recommend to use the official factory repair manual and wiring
diagrams to locate and test the [N443-Pressure Control Valve 7], it's
wiring and connections.


I'll be checking into the N443, perhaps replacing the entire valve body since that's where the N443 is located. Has anyone else experienced this issue on the 0C8 transmission? The way the problem manifested itself makes me think this is some sort of corner case in the software....or perhaps that's wishful thinking.

Curious: How much more torque than stock does that Malone tune produce?

Depends on the engine, Malone is the "trusted" off the shelf tune suppliers as they don't go nuts.

<2013 CR TDI: ~30 ft lbs increase (tiny turbo)
>2013 CR TDI: ~90 ft lbs increase

Both of those are well within the tq rating of the Aisin TR-80SD 8 speed. Interestingly, no matter what tune I use (stock or otherwise), I have the same results when towing. So either it is something in their base code or I have a transmission issue.

With miles on car (150K) and towing weight you been using past 3 years I would say you have problem with transmission or TQ, 5800LB it is lot of weight to tow.

How often did yo do transmission service and Differential service ?

It's rated to tow 6600 lbs....

Transmission has had ~3 drain and fills, differentials/transfer case were drained/filled at 100k.
