Question about 1998 Audi A4

Multi-Function Transmission Range Switch

Hi. I have a 1998 Audi A4 Quattro 1.8T and my transmission is having problems. I have completely lost overdrive, my reverse sometimes works and sometimes doesn't, when I am slowing down the last shift basically throws my car forward (hard cluncking noise/feel), and my tiptronic thing doesn't work at all. Also, I don't know if this has anything to do with it but my "P D N R" thing on the dash doesn't work. They ALL are always lit up. I took it to a shop and they told me I needed a new Transmission Control Module. So I replaced it and it did NOTHING to fix the problem. (They actually broke the clip and my boyfriend-a mechanic-had to fix it.) So I have decided to go at this by myself. I ran a diagnostic test and the code that came up relating to transmission was a Multi-Function Transmission Range Switch. Basically, the question is:
(1) Is anyone else having this problem? If so, how did you fix it and how much did it cost?
(2) Does anyone know where to get or how much the switch would cost?

I know every one tells me to take it to a shop but (a) I don't have the money and (b) they never actually help me. Just take my money :/

If you can help at all I would really appreciate it!! Thanks.

Hi.. I recently purchased a 1998 Audi A4 1.8T (Tiptronic)

I also came across the problem which prevents the reverse gear from working. The problem is called, Multifunction Transmission Range Switch. You can get the part, brand new at the Audi dealer, but goes for around $470. I got mine used from a really good German Car Shop in LA for $85.

Hope that helps a lot of you that are new to the Audi world and come across this same problem like myself.

Rather odd thing to try while i'm looking for a price .... but i've read that a method to reset that is to start it ... hold the gas pedal down abit and shut off the key will holding down the gas pedal.... hold that you should hear some clicking... that should reset it

it's been suggested that either water or rusty pins can be the cause of it.

SOURCE: Abs and stop lights are

These lights mean the ABS system has been shut off due to a fault, the brakes will fell fine but the ABS is not going to work if you need it until you fix the fault.

SOURCE: Multi-Function Transmission Range Switch

The best solution is to visit this website www.car-parts.com i know what your thinking but trust me it will help wonders. You input your info for the car and zipcode and it finds the closest location of the part your looking for. It is sorted by price and condition of the item you need.

Soudns like your transmission is slipping in and out of gears.-TCM is only necessary if it's acting up in one gear or two. The reason your display shows all of them lit is because the sensors are screwed up from your trans synchronizers being warned down. Or your not getting proper lubrication and it's causing the transmission and things like the crank sensor to give the CPU bad readings-Thus leds are lit up. I would test first for the Crank Sensor (voltage), than replace the inexpensive things like Filter and Screen, and flush and refill the fluid!-If it's manual or auto-the clutch and flywheel cannot grip the gears properly.

An overdrive is a device that allow the choice of an extra-high overall gear ratio for high speed cruising, thus saves on gas by using less torque. usually used by third or fourth gear. the overdrive sits in the back of the gearbox and is controlled electronically or hydraulicly controlled. if your sensors are flickering around in there it wont go on, or if fluid is low the hydraulic pressure wont be high enough.

Hope this helps. Good luck.

Check your transmission fluid. If you have not changed it in 75,000 miles change it. This is the cheapest fix before you look at more expensive repairs.
