2007 Audi Q7 Electrical Problems

Water leakage into the driver’s side floor panel. Water leakage seeped into battery compartment below driver’s seat which is a result of a sunroof drain problem. New Battery was installed for only 3 months before the low battery charge warning light came on. Car will not start at times. Water leakage into electrical components that lead to the MMI not turning on or working at all. The MMI shut off first, then the battery became faulty. The car has been jumped at least 10 times due to the water damage, which proposes a risk to the driver. The electrical components are being flooded, which is a safety issue and proposes a safety hazard to the driver and all passengers. The electrical is at risk for further damage. This problem has been reported by others many times. Other warning lights such as the air bag light comes on and goes off, which is a safety risk if the air bags are faulty and the driver cannot tell if the malfunction is electronics based caused by water damage.

This started happening in the last 2 mos. My MMI started acting up, it first displayed radio not installed, then it would stall and not show anything on screen, then it came back on to regular showing but then went out again and displaying radio not installed. Then at one point I was able to play my CDs but not my radio. Then finally the complete system went out, now the screen only shows the MMI logo and will not turn on and cant not be reset. So as this has happen, my fuel tank area started to drips tiny drops of gas only happens when I drove it, so now it is leaking even more fuel so I have it sitting in drive way until I get it into the shop. While its been sitting in the drive way for the last 2 weeks, I would occasionally start it but this last time I started it my battery went dead and it started leaking even more gas after I got it jumped. As long as it is not on it does not leak gas.

This is a known typical problem with these suvs. Rear sunroof drain leaks directly onto amplifier causing electrical issues throughout the entire vehicle. My vehicle actually filled up with smoke when it dried the amplifier. All mmi functions are lost. Why has this not been fixed by Audi on their dime. Dealer wants almost $4000 to fix the problem. What does it take to get a recall for this. An electrical fire or loss of life? This is the second time I’ve had this issue

THE REAR SUNROOF LEAKS AROUND THE SEAL AND LEAKS DOWN INTO THE ELECTRONICS OF THE CAR. THE DRAIN TUBES ARE RAN THROUGH THE ELECTRONICS COMPARTMENT CAUSING IT TO SHORT OUT THE SYSTEM AND CAUSING THE CHECK ENGINE LIGHT AND TIRE SENSOR LIGHTS TO COME ON AND NOT BE ABLE TO BE RESET. THE SUNROOF NOT ONLY LEAKS FROM THE DRAIN TUBES BUT ALSO AROUND THE SEAL, ALSO CAUSING THE WATER TO DRAIN INTO THE ELECTRICAL COMPARTMENT WHICH CAUSES THE SAME ISSUE EVEN AFTER THE DRAIN TUBES ARE REPAIRED. YOU CAN FIND THIS ISSUE LISTED ALL OVER THE INTERNET HELP SITES AS WELL AS YOU TUBE. THIS IS A VERY COMMON ISSUE WITH THIS MODEL VEHICLE, AND IS A DESIGN FLAW THAT AUDI IS REFUSING TO FIX AND PASSING ON THE COST TO THE CONSUMER. TO REPAIR THE AMP AND WATER LEAK IS UPWARDS OF $6000. THE CONSUMER SHOULD NOT BE RESPONSIBLE FOR ASSUMING THE EXPENSE OF A MANUFACTURER DESIGN FLAW. THE LEAK OCCURS IN THE REAR SUNROOF OF THIS MODEL AUDI AND IS A ISSUE THAT IS LISTED ALL OVER THE INTERNET AND AUDI HAS NOT MADE IT A RECALL.

AFTER GOING THROUGH A CAR WASH AND DRIVING BACK HOME I NOTICED THE AUDIO IN MY VEHICLE JUST COMPLETELY STOPPED WORKING. THERE IS ONLY THE "MUTE" BUTTON STUCK ON THE DASHBOARD AND THERE IS NO SOUND COMING FROM THE MMI SYSTEM AT ALL. ALSO WHEN I TURN OFF THE VEHICLE YOU CAN HEAR THE PHONE BUSY SOUND COMING FROM INSIDE OF THE VEHICLE SOMEWHERE SO CLEARLY SOMETHING WAS WRONG. ONCE I GOT BACK HOME AND PARKED THE VEHICLE I DID A VISUAL INSPECTION AND FOUND THE REAR RIGHT AREA SOAKED WITH WATER , THERE WAS AN OVERWHELMING SMELL AS IF SOMETHING ELECTRICAL HAD MELTED OR CAUGHT FIRE. THE NEXT DAY I CONTINUED TO SMELL THIS FAINT BURNT WIRE SMELL WHICH DEFINITELY CONCERNED ME. KEEP IN MIND MY AUDIO IS NO LONGER WORKING AT THIS POINT AND HAS NOT RETURNED I BEGAN TO REMOVE ALL THE ITEMS IN THE REAR LIFT GATE PORTION OF THE VEHICLE AND STARTED TO DISASSEMBLE THE REAR RIGHT SIDE TO INVESTIGATE IF IN FACT ANYTHING HAD CAUGHT ON FIRE OR HAS THE POTENTIAL TO DO SO. WHAT I FOUND WAS, THE BOSE AMPLIFIER WAS COMPLETELY DRENCHED AND OTHER ELECTRONIC COMPONENTS DOWN ON THAT SIDE WERE WET AS WELL IT LOOKS TO BE A BACKUP IN THE DRAIN TUBES. AFTER LOOKING ON MULTIPLE FORUMS ON THE INTERNET I FOUND THAT THIS IS REOCCURRING ISSUE WITH THIS PARTICULAR YEAR AND MODEL Q7 THAT AUDI IS WELL AWARE OF BUT SURPRISINGLY NO ONE HAS STARTED A CAMPAIGN TO HAVE THIS ISSUE ADDRESSED. MY BIGGEST CONCERN IS THAT IT CAN POTENTIALLY START A FIRE IN THE REAR DO TO THIS OBVIOUS DESIGN DEFECT AND ALSO MY ELECTRICAL COMPONENTS HAVE BEEN DAMAGED BY THIS DESIGN DEFECT. PLEASE HELP!!!!!! THANK YOU.

MY AUDI Q7 HAS A LEAK FROM THE SUNROOF, WHICH DAMAGED THE BOSE AMP, BECAUSE OF THAT, THE RADIO, BACKUP CAMERA, THE WHOLE MMI SYSTEM IS NOT WORKING. ALSO FOR THAT REASON THE BATTERY IS NOT HOLDING ENERGY, THE AMP IS DRAINING THE BATTERY. THIS IS AN FACTORY ISSUE, I TOOK THE CAR TO THE DEALER AND WAS TOLD IT WILL COST OVER $4,000 TO FIX IT. AUDI OF AMERICA SHOULD DO A RECALL FOR THIS ISSUE, WATER GETTING IN CONTACT WITH THE ELECTRICAL PART OF THE CAR IS A BIG HAZARD, IT CAN START A FIRE OR OTHER PARTS OF THE ELECTRIC SYSTEM COULD MALFUNCTION, AND COULD EVENTUALLY LEAD TO AN ACCIDENT. I'M NOT SURE IF THIS WATER LEAK DAMAGE THE PASSENGER AIRBAG BUT I ALSO GETTING A LIGHT FOR THE AIRBAG ON THE CLUSTER.

THERE SEEMS TO BE LEAKING FROM THE SUNROOF THAT LETS WATER INTO THE AMP. THE LEAK GOES INTO THE AMP AND CAUSES THE BATTERY TO DRAIN WHEN SITTING. THIS ISSUE HAS BEEN KNOWN BY AUDI FOR A WHILE AND HAVE NOT DONE ANYTHING TO RECALL THESE VEHICLES AND FIX THE ISSUE. THE AVERAGE COST TO MAKE THE AMP AND ROOF REPAIR IS $4,500. PLEASE LOOK INTO THIS. THANK YOU.

Incident

Sep 9, 2007

ELECTRICAL ISSUE DUE TO THE FAULTY SUNROOF WATER DRAIN HOSES(CONNECTION FOR HOSES). LIKE ALL (ALL) AUDI Q7 OWNERS I HAVE ENCOURAGED PROBLEMS WITH MY COMPLETE ELECTRICAL SYSTEM IN THE CAR. WATER LEAKED FROM SUNROOF DOWN TO MOST ELECTRICAL COMPONENTS IN THE CAR WHICH ARE HIDDEN BEHIND UPHOLSTERY. AUDI IS FULL OF ELECTRONICS INCLUDING SAFETY SYSTEMS IN THE CAR. MY MMI SYSTEM DIED DUE TO AMPLIFIER GETTING WET. AFTER MMI, BATTERY DRAINED OUT AFTER JUST 7 HOURS THAT CAR HAS BEEN SITTING IN THE PARKING LOT. ALL DEALERSHIPS KNOW ABOUT THIS AND AUDI IS STILL RIPPING OFF ALL THE Q7 OWNERS ON THIS ISSUE. TOO BAD IS THAT IN LONG RUN THEY WILL LOSE A LOT OF CUSTOMERS.FULL REPAIR OF SUNROOF HOSES AND REPLACEMENT OF AUDI AMPLIFIER WHICH IS FIRST PART THAT GETS AFFECTED FROM WATER COSTED ME ALMOST $4000. NOT TO MENTION THAT I STILL STAINS FROM WATER ON MY ROOF LINER. I CONTACTED AUDI OF AMERICA AND THEY WILL NOT ADMIT FAULT, WANT ME TO GO TO DEALERSHIP AND PAY AGAIN FOR INSPECTION. YEAH. GOOD LUCK. I WILL NEVER SEE AUDI DEALERSHIP AGAIN AND NEVER BUY ANOTHER AUDI.

HI THERE, I HAD AN ISSUE WITH MY SOUND SYSTEM I.E. IN MY AUDI Q7, IT BASICALLY MUTED OFF AND I COULD NOT HEAR NOTHING (RADIO, AUDIO CD ETC.) AND TOOK IT TO THE DEALER. AFTER DIAGNOSIS, I WAS TOLD THAT MY MOON ROOF DRAIN TUBES WERE CLOGGED AS A RESULT RAIN WATER TRICKLED IN AND EVENTUALLY BLEW UP MY AMPLIFIER AND THE DEALER IS NOW CHARGING ME AN EXORBITANT (~$2500) PRICE TO FIX IT. I HAD NO OPTION BUT GET IT FIXED. BASED ON MY RESEARCH, I SEE THAT THIS IS A KNOWN ISSUE WITH THE 2007 AUDI Q7 MODELS AND THAT IT WAS AUDI'S DECISION TO DEAL WITH THIS ON A CASE BY CASE BASIS IN PREFERENCE TO RECALLING ALL 07 PRODUCTION (UP TO A CERTAIN VIN) WITH SUNROOF FITTED. THEY HAVE KNOWN ABOUT THIS PROBLEM FOR YEARS. THEIR ARGUMENT NOW IS THAT I HAVE NOT BEEN REGULAR AT SERVICING MY VEHICLE AT THE DEALER THEREFORE THEY CANT HELP WITH ASSISTING ME TO FIX IT AND ARE IN NO WAY LIABLE FOR IT. I WOULD ARGUE THAT THEY HAD A DUTY ALL ALONG TO FIX IT OR ADVISE ME OF THE POTENTIAL PROBLEM. I AM VERY FRUSTRATED WITH THE FACT IT WAS HIDDEN FROM ME AND CALLED THE AUDI CUSTOMER SERVICE AND THEY TELL ME THEY CANT HELP ME WITH THIS. I AM NOT SURE WHAT I FOUND ABOUT THE MOON ROOF DRAINS IS TRUE, BUT IF IT IS TRUE, THEN I THINK IT IS UNFAIR FOR AUDI TO HIDE THE FAULTY DRAINS FROM THEIR CUSTOMERS AND AUDI SHOULD BE LIABLE FOR IT... THANKS

AS MANY PEOPLE HAVE ALREADY REGISTERED COMPLAINTS ABOUT, EVEN WITH CLEANING OUR SUNROOF DRAINS REGULARLY, THE GLUE FAILED CAUSING US TO NOT ONLY ENDURE THE EXPENSE OF A WELL-DOCUMENTED ISSUE WITH THE VEHICLE, BUT NOW WE HAVE BEEN WITHOUT A STEREO SINCE WE FEEL WE ARE ENTITLED TO AT LEAST THAT MUCH, HOWEVER, AUDI OF AMERICA DISAGREES. CONSIDERING HOW MANY ISSUES THERE HAVE BEEN WITH SUNROOF LEAKS IN THE PAST AND THE FACT THAT THIS IS AN ONGOING PROBLEM FOR Q7 OWNERS, I FEEL, AS MANY OTHERS DO I'M SURE, THAT THIS PROBLEM NEEDS TO BE LOOKED INTO FURTHER BY THE NHTSA. *TR
