Replaced battery Dash gaughes instrument panel not powering or working help please.

new audizine member heard alot about the site love my car and need some help. so thank you in advanced for any help. I have a 2003 a4 b6 1.8t fwd recently battery died and i replaced upon replacing it my instrument panel stop working. some of my dash lights come on like the ESP and ABS and Air bag. my center screen still works and my mileage and clock still work but are not lit up and can barely see them. the speedo techo temp and gas gauge dont even budge and the instrument panel wont light up at all. ive check every fuse in the car is fine. new battery so its good, checked all the connectors and even wiggled the ones near the ecu where the wires from the instrument panel run too and it still wont power up the gauges light etc. im stumped i took it to my mechanic who is very helpful and knows alot about audis and he did a vag-com test and said that the instrument panel wasnt getting power so he couldnt do the test because it wasnt communicating with him. i can still operate the car no emob so far thank god and i dont want to trip that and have to take to dealer i am a student and dont make alot of money. my signals still work but not on the instrument pannel. upon disconnecting my instrument panel i notice that the blue connector on the left wasn't doing anything when connected or disconnected so i assume this is the problem or part of the instrument panel internally is not working. so my mechanic is printing my a wiring diagram which i will get from him tomorrow. but my question is should i test the blue connector for power ? and if so then it means my instrument panel? my mechanic says there is a small transistor thing in the instrument panel that might have burn up and might need to be sent for repair or he has a micro sauter tool and may be able to fix if that is indeed the problem. another to note is when i disconnect my instrument panel fuse or unplug the blue cable from the instrument panel my heating/ac lights come on by themselves?? weird. any help would be appreciated because i dont know really where to go from here. thank you.

I'm gonna take a stab and guess CCM, comfort control module? Oh welcome to the B6 club, I just joined about a month ago with my wife getting a B6. I've been on here though since Ver. 1 with my B5 and still learning the B6! good luck!

[headchange43]

thank you for your quick response. i am not familiar with the CCM and do you think that this could affect my instrument panel and gauges? maybe explain why the random light comes on my a/c heat when i unplug left instrument panel plug and instrument panel fuse. for some reason my instrument panel isnt getting the juice it needs and i think its because of when i connected the battery im just hoping its something else so i dont have to send the intrument panel off for repair. thank you

If you disconnect the battery or have a low battery, the gauge cluster can go haywire and not work like you described.

It will eventually fix it self or you can disconnect the battery again to try and trick it back into service, or you can also scan the cluster with a VAGCOM and try and reset it.

According to the OP, the IC does not communicate with VCDS because it has no power. OP,how do you know the fuses for the IC are not blown? Did you actually remove ALL the fuses and inspect each fuse? IIRC, the IC uses 2 fuses. Part of the IC is getting power, or the car won't run because of the immo. The CCCM has nothing to do with this.

[headchange43]

I'm not familiar with all the abreviations I'm sorry. I've check every fuse in the fuse box the 2 hidden under the bottom dash the 50 and 60 amp and checked both the 15 and the 40 next to the ecu inside the housing. Have driven it for over a week hasn't reset and disconnected the battery multiple times for various times and no luck. I don't know how to check relays if there are any but out of every fuse I could get to cant find one that's blown I can add pictures if that helps but any ideas? Thank you all again do much for the advice with this.

it really sounds like a bad fuse

I've check every fuse I could get to and then some the panel of fuses the hidden big fuses above my gas pedal and the 2 fuses next to the ecu. You say there are 2 fuses for the IC? I checked the obvious one the 15 slot for IC and navigation. It's fine and checked with dc meter an it's getting power to the fuse. The second fuse which one is that? Thank you again.

[headchange43]

does anyone have any other suggestions or maybe the 2nd mystery fuse location aside from the obvious 15 amp fuse? thank you again im just stuck with no gauges when i drive :(

[jubei4769]

im a look for that other fuse for you

Thank you for this. Now is this the layout for the connectors to the back of the IC? The blue and green just broken down? I'm starting to think part of the cluster failed too but wouldn't hurt to check power to the IC which wire should I check and with a dc volt meter right? And should I shave the wire to be able to test it? Thank you again very much for this all of you from audizine have been very helpful and I am very impressed. Another thing when my IC stopped working my headlight range control light came on my center screen? So should I check the headlight range control problem. Or test the green connector to IC for power and then last send of IC to company for repair and hope they don't screw up my immobilizer? Thanks

you shouldnt have to shave any of the wires, get meter leads that will fit into the pins of the connector on the back side of the pin

Wow holy **** I climb in my car this morning it's early half my car is still taken apart. And it's rained all night so I've been covering my ecu. Anyway long story short MY FJiNg Gauges are working!!!!?!?! Seriously? How is this and it just happened to be at my girlfriends where they went out in the first place. I guess the audi god visited me in my sleep. Anyway the fuel gauge isn't working so I'm gonna give that some time to reset itself I guess. Thank you all so much and I hope you all have awesome weekends.

Something smells really fishy here...

That doesn't sound like a loose wire on the back of the cluster or a fuse issue.

[diagnosticator]

Yeah, sounds like the IC suffered a high voltage spike when the battery was dis/reconnected. If that is the case a new or good used IC will need to be installed by the dealer to fix. The dealers have the IC priced on a reman exchange basis.

I agree with you completely thank god my IC wasnt dead. What I think happened is when I reconnected battery I did negative first which I shouldn't I was doing it backwards. I think it spiked and shut down that part of the IC for a week and a half and all of a sudden she kicked back on. Stopped and put gas in this morning and slowly but surely the gas gauge reset so everything back to normal and I just got done reassembling everything. I guess we can call this one closed for now I don't have the funds for a new IC right now so since mine has rebooted she will have to do for now. Honestly I couldn't be happier right now. Thanks everyone again for all the help I am officially an audizine fan. So when do I get my t-shirt? Haha Jk

[headchange43]

thought i would add some pictures.

before IC not working. -

After reassembled car idle. gauges and IC working -

That is good news! You got lucky this time. Thanks for the update. Welcome to Audizine!

[NonRicer]

Having trouble finding + and - on the clips, which pins power the cluster ? I wanted to try and test mine one last time before buying a new one
