Question about 2005 Audi A6

1 Answer

Allroad Tiptronic Gearbox "holding" gears before changing up.

Hi.

My 2005 Allroad 2.5 TDI (5 speed tiptronic) is not changing up quickly enough resulting in excessive revving of the engine between gears.
I has been into my local Audi garage on four different occasions but they seem unable to help. - - They changed the transmission fluid on the last visit but to no avail.
Interestingly it worked perfectly until the car had it's first service.

    Many thanks for your suggestion. - - The car has only done 35,000 miles and this has been a problem since 15,000 so would be surprised if the gearbox requires an overhaul. - - I will try a different garage in January and mention the air mass sensor. - - Will let you know the outcome.

    hi, i have a 1998 2.8 quattro a6 tiptronic. it also seems to hold in the gears too long, so you could be doing 40mph and will hold in second instead of changing up. but it all the gears are fine in the "manual mode". It also sometimes cuts out at junctions as you pull up, could this be conected?

    regards stuart

Have you had the vehicle put on a diagnostic machine, does the car feel slugish, any lack of power, we have seen a lot of these vehicles with air mass sensor faults. When they fail they do not show a code but with the right scanner they can be seen not working. This affects the gearchange because the ecu does not have the correct data to shift. Of course it could also be the transmission is in need of overhaul. but i would take it to a good diagnostic garage first. It is not uncommon for the air mass sensor to fail after it has been disturbed or knocked in the workshop. we have never found out why.

My 2004 Audi A6 tdi can only get up to 2nd gear in auto or tiptronic. Auto gearbox garage said it is the engine - VW/Audi garage said engine is ok. No fault codes or dash warnings. was on the motorway...


Is it not shifting into third gear (meaning you're at redline and the car won't shift), or is there not enough power to get the car going fast enough to warrant going into third gear? Have you checked to see if the car is in limp mode?

Freelander tiptronic shifting failure


You say up and down hill. Does it work OK on the flat? If so, there is a sensor for detecting the fact that you are going downhill and this holds the gear you are in when in auto mode to achieve engine braking. I believe failure of this should throw a fault code in the gearbox control unit if this is the case. It could be that the failure of this sensor is inhibiting tiptronic mode, but I can't be sure. Either way, get the dealer to read the codes from the gearbox, not just take it up the road and say they can't replicate the fault.

2006 Jetta TDI Tiptronic Maintenance


The tiptronic is not the DSG - two separate transmissions. You don't need to service the tiptronic every 40k like you do the DSG.
VW considers the fluid in a Tiptronic tranny as "lifetime" fluid - it doesn't need to be changed.

Prelude 2.2 vti W reg auto automatic tiptronic gearbox slipping


Hi there. Although the Dealer has changed the oil, did they do a 'Stall Test' whilst the gearbox was cold and again when at normal running temperture? If not, that's what they must do firstly. This will identify whether you have a slipping clutch/s. The Honda autobox also includes what is known as accumulators - these control how each clutch is engaged during acceleration. For example, if you are accelerating slighly/smoothly, you want each gear to be engaged gently and smoothly, whereas, when accelerating hard, you need the gear engaged quickly and hard to aviod clutch slippage. Thus, the fact that you are experiencing a hard engagement might mean that an accumulator/s is seized. If that's the case, it will mean that the autobox will need stripping, cleaning and be checked for worn components. Hope this helps, Scottech.

AUDI A6 SIX SPEED TIPTRONIC GEARBOX SEEMS TO BE IN WRONG GEAR AND APPEARS TO HAVE SLIPPING


I have been having similar problems. The clutch is slipping as thats how you get the variable gears when in full auto, but this is where the problem comes from, some garages (auto gearbox specialists) are now able to fix it. Do not go to Audi as all they do is replace the gearbox (very expensive). There is no quick fix though! Sorry for the bad news!!
