- Why in automatic mode some Multitronic boxes have
6 speed, while other 7?
Those speeds are "memorized" by the computer positions of the
disks for defined speed. After 2004 Audi is selling 7 speed
Multitronic, but this is more like an advertisement. The
cones are positioned and moved absolutely the same way.
- Why some cars have position "С"?
Those are Audi cars, build after 2004. In this case the
gearbox is trying to use the "memorized" data to improve the
performance.
- Is it suitable to use chip tuning with a
Multitronic, as the gearbox that is designed for maximum of
400 Nm?
Like all chip tuning activities, there is a certain amount of
risk. If your gearbox is in perfect shape, it will not
affect it heavily. If you have any issues with the box, it is
better to avoid loading it additionally.
- Is it possible to tow a multitronic driven car?
The official position of Audi is that it is possible for 50
kilometers, with a speed no bigger than 50 km/h. This is
caused by the fact, that one of the shafts is not getting
lubricated with oil, while the box is not working.
- How often do you need to change the oil and the
external filter? The oil must be changed every
60000 km., together with the external filter. When changing
the oil use only Audi one - the original ones are G052 180
А2, G052 180А6, G052 180 А9, depending on the type of the
gearbox.
- When should I change the internal filter?
Usually after 180000-200000km, concerning that the chain has
about 3600 hours or 300000km life (LUK information) - normal
driving (no sudden speeding from start).
- What breaks most oftenly in the multitronic?
Generally everything! The chain, the command block, the
bearings, the cones of the chain, the primary shaft.
- Does an irregularly working ABS/ESP influence the
gearbox?
Yes, because the computer of the gearbox provides constant
communication with the ABS controller. Thus, the control of
the cones and the primary shaft is disturbed.
- Is there a better acceleration (performance) using the gearboxes build after 2004?
YES, this is achieved with optimised parameters of the variation unit, oil power unit and the gearbox ECU
- Is it necessary to make a full inspection, when
there is an external damage to the gearbox body? YES, if there are hidden leaks, caused by the external damage it is possible that the oil level inside the box is going down. That causes damage to the cones and the gearbox can not be repaired – it has to be replaced with a new one.
- Can it be determined what the condition of the
cones is without opening the gearbox for a full inspection?
NO, we can get only general feeling on the cones condition by carefully examining the gearbox behaviour.
- Is it possible to repair the differential of the
gearbox, when there is visible damage on it? NO, it is not possible to repair the differential due to the fact that the two movement mechanisms are produced together and they represent a unique couple. To avoid problems with the differential it is necessary to change the oil inside (G 052 190 A2 – two litres) every 80 000 kilometres.
