I have a audi 2.8 v6 automatic 1996. I cannot get reverse gear on the car. If I put the car in drive it holds back before it goes to the front. The gear indicators on the dashbaord are all lit up. Don't know which gear I am in. Please help.
2002 A4 1.8 Quattro. Brought the car in to Canadian Tire for them to check a mysterious oil leak. They shampooed the engine to clear the engine area for a better view (I guess) and added a dye in the oil (to locate the leak) and proceeded to run the engine for 1 hour to check for leaks. They phoned me to say there was no leak and to come and get the car. Paid $100., got in the car, put it in D, heard a small clunk and then the car would hardly move without having to push way down on the gas pedal. Tried to reverse but it would not move, PRNDS all lit up, engine light on and the engine runnig ok ( sputtering a little) What the heck is going on? Left the car there after vowing to return to speak to the manager- it was 5:45pm. Is it possible CdnTire caused this or is it coincidence? They do not have a fault code reader and admit BMW and Audi are not their strength....so why do they service them? Sure take the money and when things go wrong ...uh it's not our fault you will have to go to the dealer for that! I will have to do that and see if that is the case and sue them if they are to blame.
That car is full of sensors if they sprayed the motor with a hose or what ever it could trigger any or all of the sensors to read off you can take it to most any reliable mechanic shop and have them hook it up on a computer dianostic machine for some where around 30 to 60 dollors. If you just want the codes the the computer will give you a code reader on cost about 90 dollars and they work on most any vehicle from 96 and up all you have to due is plug them in and follow the instructions on the screen they are simple to opperate.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

1. check the main power fuse up front under hood. 2. check the fuses on the amp. 3. check the power wire if you didnt reverse them 4. check if your remote wire works 5. check if you have a proper ground 6. if nothing else works the amp may be defective
Yes, the amp can be used to power normal speakers on 2 channels.
The best way to wire the amp to a stock receiver (head unit) is to use a pair of wiring harnesses, one the standard harness that plugs into the vehicle wiring, the other a "reverse" harness that plugs into the stock receiver.
First remove the plug from the receiver and plug in the "reverse" harness. Run the speaker leads from the reverse harness to your amp inputs or to a line output converter (LOC) and RCA's to the amp. Then run the amp speaker outputs to the standard harness speaker wires. Plug the original receiver plug into the standard harness and splice the remaining wires, 12V constant, 12V accessory, ground, illumination, etc, together. Connect the 12V switched wire to your amp remote terminal.
Hiya, dont have a diag either what you will have to try and is compare the left channel with the right. There will be 2 driver transistors (also likely on heatsink) close to the outputs. Check which driver drives which output on the left, then match it on the right. Those same drivers could very well also be a problem on the right as they often go with the outputs. There is a possibilty they have smoked again. See here to test FETS http://www.4qdtec.com/mostest.html
Basically the left will match the right but not similar locations but definitely by track joins.
Also check the power resistors at the output. Often also go.
These amplifiers dont employ reverse polarity protection that most higher priced ones do.
The amplifier(s) are definately in need of repair - probably power supply - IF boss sells parts.
Chances are, however, the repair will meet or exceed the cost of a new (appropriately rated) entry level amplifier.
Just about anything can be repaired.... question is, are you willing to pay?
If it was properly fused, the fuse should have blown without causing any other damage. If it was not properly fused, it probablycaused the reverse protection diode to short and burned a trace on the circuit board.
Any competent repair shop should be able to repair it unless the reverse protection diode opened instead of shorted. If it opened, the damage could be much more severe.
If both the left front and left rear channels are out, reverse the RCA cables to determine if the problem is signal related. If the left side plays when you reverse the RCA cables, reverse them at the head unit to see if the audio changes sides. If it does, the head unit is likely the problem. If it doesn't switch sides when you switch at the head unit, the RCA cables are the problem.
I have found the problem to my Kenwood KAC-7202. The amps fan was the only thing that would come on thats it. So I started checkin zener diodes cause all transistors checked out fine. So I remember readinf about a guy that had same problem and took it to a shop and they said it was some diodes. Well, thats what I was thinkin or the transformer. It turned out that 1 zener diode was no good, diode D9 1ss133. I took a zener out of an old vcr I use for parts and put it in and the fan came on as usual then the red light. Then I hooked my mp3 player to the rca input and hooked up some speakers and it works great. Hope this helps you other guys with the same problem. Check your zener diodes with a digital volt meter, if you get any measurement other than the reverse impedance which will read between 600 and 1200 ohms some lower or higher and then reverse the leads on your meter and if you get any reading it's no good and the reading will be 0-50 cause mine read 047 ohms.
The fuse blows due to a fault in the circuitry which can be: the final transistor pairs or in the DC to DC converter (if it is present) or shorted reverse protection diode (which only happens when the amp is wired wrong even if for just an instant). In any event, it would require going inside. You have to be familiar with component level repair to correct the problem, otherwise it would be best to have an electronics technician have a look at it.
Hope this be of some help and pls post again how things turn up. Good luck and kind regards.
