Hi, welcome for every one.
Im just new here five minutes ago.
It's first time to own audi, I bought audi a4, 2002
released september 2001, but in the registration card its 2002

Any way. the problems i have are:

*The PRND is always together on the screen and flashing(going and coming).
*when I put the gear on R the car goes back strongly suddenly(slipping) and its stable on one speed even i accelerate the gas but it does not get faster.
*some times (making me mad) when im driving i remove my foot from on gas, and put it again, i find the RPM coming up and the sound of the engine gets higher, but the car does not respond, i need to wait and turn on waiting lights and wait till i stop the car and may need to turn it off and then on to start to drive normally.

all of this made me mad, I took the car to computer check, he gave me a report with the following:

P0706 TRANSMISSION RANGE SENSOR CIRCUIT=>F125 RANGE/PERFORMANCE.
P0722 OUTPUT SPEED SENSOR CIRCUIT NO SIGNAL
P1602 VOLTAGE SUPPLY-TERMINAL 30 VOLTAGE TOO LOW

PLEASE GUYS GIVE ME SOME PATIENCE, IM NEW TO AUDI BRAND AND I'M LIVING IN QATAR, WHERE THE PARTS ARE VERY EXPENSIVE AND LABOR CHARGES AS WELL.
SO I DONT LIKE TO GO TO WORKSHOP AND THEY TELL ME SOME THING WRONG AND MAKE ME PAY MUCH FOR NONSENSE.
I EXPLAINED WHAT I HAVE DURING MY DRIVING AND WROTE DOWN WHAT THE REPORT SAYS. PLS WAITING FOR YOUR GENEROUS HELP.

THANKS AND REGARDS FROM MIDDLE EAST.

0706 is the sensor in the center console that detects what gear your in.. It could just need adjusted..

0722 is the sensor that tells your tranny speed in relation to the engine. Its located on the top of the transmission (below the battery box)..

Your tranny is in limp mode.. Which is it basically trying to protect itself.

 

THANKS CRYTOSTORM

HOPEFULLY U GIVE SOME MORE PATIENCE.
OK, WELL
YOU ADVISE TO REPLACE WHICH ONE URGENTLY?
YOU KNOW? THE MOST ONE MAKES ME SCARED,
*some times (making me mad) when im driving i remove my foot from on gas, and put it again, i find the RPM coming up and the sound of the engine gets higher, but the car does not respond, i need to wait and turn on waiting lights and wait till i stop the car and may need to turn it off and then on to start to drive normally.
IT MAKES ME STOP ALL THE CARS BEHIND ME.
REGARDING THIS ONE, WHAT I CAN DO?
OTHER THINGS CAN BE DELAYED OR CAN BE REPARED LATER.

WHAT DO U THINK ?

 

It would be hard to tell you which one to fix as they're both important... I guess the one in the console will be much easier to get to and potentially free to fix.. Try and get that working, clear the codes, and see if it comes back..

The sensor on the tranny is much more involved to get to.. It might not even be something you want to attempt yourself.
