Some Audi owners with the CVT Multitronic transmission experience some problems when the Car comes to a stop, the car shakes and hesitates and seems Not to respond to the accelerating pedal anymore !
The problem only exist in the D or S gear selection.
The most complain and help calls we receive, explain the situation as follows: In selector position D or R the Rpm doesn't rise up anymore and the car won't move at all, he is NOT responding to any accelerator pedal.
After one drive cycle, this means, one turning of ignition and turned on again, the car resets itself and will drive again.

The most  problems we experience with the CVT transmission, is a failure in the valve body, (hydraulic control unit). The dirty oil with particles in the oil cause a sticky valve body with hydraulic malfunction. Instead of a smooth movement of the reaction valve, a high pressure rises up on the sticky reaction valve and forces the valve to close with a bang shortly before the car comes to a stop and should shift in the first gear, but he doesn't !

Attention: This problem in the Tip selection cannot occur because here the unit shifts earlier in the first gear!

It is Important to check the transmission fluid, if you have metal particles in your oil, in the size of one millimeter or more, save your time and money, you need to replace your transmission. The oil has a burnt smell, it is likely that your frictions are damaged and need a replacement with new filter, etc..

To find out now, if your Valve body or something else is the problem in your transmission, let me give you the following hints, this is more for the professional mechanics with the proper tools.
Before the test drive, read out the value of Block 65, write down these values and then turn off and on the ignition and perform a test drive with a minimum of twenty stop and go cycles (really stop to "0"). Read out again the Value block 65. If the result is smaller or 0 alls on the first reading, you have no problems on your valve body, otherwise you need to replace your valve body.
The value Block 65 counts the reaction of the safty valve (SIV) by known hydraulic malfunctions, to reduce the clutch pressure in the shortest time. After too many counts, you have to reset the computer (value Block 65). For this reason you have to cycle your ignition on and off. By the earlier CVT transmission to 2003 after this year a new valve body design with self flush capability is designed.
For cars after 2003 with the new design valve body for the CVT transmission, the computer tracks the value block 65 and resets itself when you will and he activates a self flushing process and cleans the whole valve body by itself. A successfull cleaning is stored in the value block 65 he counts all cycles. This is too complex to explain here, look in our help section.

Many shops and mechanics experience a hesitation by acceleration on take off, here bear in mind after a repair an Adaptation or learning process has to be performed.
The hesitation on the acceleration is the reason that the clutch values from the computer are not recognized and have to be relearned, you perform this process in the time your test drive and activate the  brakes and simulate a Torque of 15 Nm on the clutch.
