Hi i have an Audi A6 3.0 V6 TDI Avant 2011, it has 160,000 miles, I have recently had a warning on dashboard coming up saying:

Gearbox overheating please adapt driving style

I have plugged a diagnostic in and coming up with the below code

Code: P17D800 (please see picture)

reduced tourque due to clutch temperature.

Warning comes and goes randomly and stays on for a couple of seconds and goes off. 

Is anyone able to help with what could be causing the issue ?

 

Hello Byron,

Manual or automatic?

Are you driving the car ‘enthusiastically’ ? 
Kind regards,

Gareth.

Hi,

 

It's an automatic S-Tronic, I am driving sensibly and sometimes the fault on dash won't show for 30 minutes of driving and sometimes will show within 2 minutes of driving.  I've even had the fault come up on the dashboard when the car was left running for 10 minutes and the gearbox was in park?

Thanks Byron,

When was the gearbox oil last changed? 
Kind regards,

Gareth. 

Hi Gareth, 

 

Thank you for the reply, it was changed 8,000 miles ago 

 

Kind regards

I would anticipate that this was the ‘full’ expensive gearbox service -? Approx. cost, and do you know the extent of that gearbox service? 

If so, I think it would be a wise move to return the car to them ( if them= specialists) and seek hands on inspection there.

Kind regards,

Gareth.  

Hi Gareth, 

I have attached a copy of the invoices and what was done 

Thanks

Hello Byron,

Many thanks indeed for the comprehensive extra detail.

I hope this isn’t seen as being dismissive on our part, but if this were mine, I would be entrusting the car back to S.D. since the invoice shows an expected still-within-warranty date of 27 Feb. of next year.

It seems to have been complicated by the electronics, and it might just be a simple case of some associated poor connection. 
I really hope they can sort it for you - without any more major expense! 
Kind regards,

Gareth.
