audi a3 have inbuilt amp so lollopop tester why need

@Mechani_Cole

18 күн бұрын

Even if it's built in, the fiber optic loop needs to be tested to confirm that it's actually receiving signal. If there is a break anywhere in the fiber optics system then it won't work. The tester completes the loop, bypassing the amp (or other modules) to confirm its good

Literally just ordered my piece! Thank you for the link as well. One day my battery died and all of a sudden I started dealing with this issue.

I didn’t spill a drink on the hardware or anything major. Just doesn’t add up, so hopefully it fixes the issue somewhere with maybe one bad part that isn’t too much to fix.

Hey bud great video. Having some intermittent issues with my screen not turning on, particularly in cold weather. Same thing buttons don't light up either. If it's intermittent, is it most likely still the tuner? Or is there a connection I can fit tighter or dry out if there's moisture?

Great question, and thanks for the comment! First thing I would check for is moisture damage on/in any of the units. The MMI controller located near the gear shifter could also be bad.

Hey man my amp on an 09 S5 got damaged from water going through the trunk, I ordered a very similar replacement just a 2011 amp instead of a 2009, my local mechanic "who identified it being the amp which was the problem by using the same method as you) attempted to code it for me but says he needed a special type of system which he didn't have, I took it to audi dealership and they could also not code it because one of the modules but somehow didn't want to get further into it because I had originally paid an hour labor just for them to try to code it. Wondering if I should get the exact part number for amp or it could be something else? Really appreciate you helping with these mmi problems 🤦🏽‍♂️

@Mechani_Cole

Жыл бұрын

I would recommend finding the exact part number and getting that instead. When I replaced mine I found the same part number on Ebay and it was plug and play with no coding needed

I’ve seen videos where the loop is used indefinitely. Will that work or do you have to replace the part?

@Mechani_Cole

3 жыл бұрын

That will work, but you won't be able to use what ever module you are by-passing. For me it was the FM receiver and it was cheap and easy to just replace it. But if its the cd player or something, it won't matter to much. Thanks for watching!🤙🏼

i was able to isolate my problem in being my amplifier, yes that is a shock! haha. anyway, do you know if the power supply must be connected to the amp if you are checking the loop? i took my amp apart and cleaned off all of the corrosion on the inside, and am ready to test and see if it works. However, the power connector is a real pain to plug in and unplug. Without plugging it in, just plugging the fiber optic loop in, will that make the connection??

@Mechani_Cole

2 жыл бұрын

Good question! I don't believe power needs to be hooked up. Main reason is all the fiber optic lollipop tester is for is to complete the fiber optic loop. When the amp or something fails, the fiber optic loop is broken somewhere causing the whole system not to operate. The loop by passes whatever module is dead by connecting the broken fiber optic link if that makes sense. So if you unplug your amp, plug in the tester, and you see your radio and other things work, then you most likely need a new amp. Best place is ebay, hope that answered your question🤙🏼

Good question. First step, test your battery for correct voltage. I have seen bad batteries cause this before. Next I would get the fiber optic tester and test each module in the trunk like in the video. If you get a drastic change when olugging the tester in, then whatever module you tested is likely bad. For me, it was my Am/FM reciever that was bad and caused the whole system to fail. Hope that helps, best of luck!

Hi Coleman, just purchased an audi q5 2012 and the MMI powers on, navigation works, you can hear the navigation voice, but the radio volume doesn't work, nor can I adjust the bass, balance, fader, treble etc. I've replaced the console control panel and everything remained the same. So thinking it's either the receiver or amp. I tried the loop on both (admittedly, not really know what I'm doing-learning on the fly). Any idea what I should do next? replace amp/receiver? thanks for help

I noticed there is a fiber optic cable laying there with a red light pulsing out of it. I don't see another module it could be connected to so this unused fiber optic plug with the red light pulsing that is just sitting there unused off the harness is causing a break and preventing the stereo MMI from turning on?

@Mechani_Cole

Not usually no. The red light you are seeing is the fiber optic signal. It appears red. You can always try plugging it with the tester and see if that fixes it. The tester completes the loop, which needs to be a complete circuit.

Similar process. Locate the modules in your A7 (Google super helpful here), then remove the bracket holding them in. Remove the fiber optic connection on 1, plug in lolipop tester in link to the wire harness. Then turn the car on and see if any difference. Repeat this process until something changes on each module. Once you find which plug makes a connection with tester, then remove and replace module. You can also leave the tester in as a temporary solution. Basically the fiber optic tester creates a complete loop in the fiber optic signal. When a module fails, the connection is broken/interruption. The connecter completes the circuit to by pass the module is all that makes sense. Best of luck, thanks for watching🤙🏼

I have a similar problem, no screen at all, not even briefly. I have just tested the optical loop for the four components in the trunk. One by one, I replaced a component by a lollypop bypass, nothing changed. The CD changer in the glove compartment has its lights on, but I cannot make it do anything else except a long hold on the main button to turn the lights off. So, it may be the board itself, since no lights are there, or the screen (doubtful) since all the buttons are affected, or possibly the CD changer (not clear why the screen doesn't come up at all).

Unplug the connector from the back of the module, then insert loop into the end of the plug that you just removed. Then turn on to see if any changes. If it turns on or changes when plugged in, then that is your faulty module. There is 4 or 5 modules; - AM/FM Receiver - Navigation - CD Player - Amplifier Test each plug. The tool completes the fiber optic loop, if one of these modules is failed then it breaks the loop, therefore shutting power down. Hope this helps🤙🏼
