2004 Volkswagen Jetta

OVER THE PAST FEW DAYS IT HAS BEEN RAINING HEAVILY & ALTHOUGH IT HAS HAPPENED TO ME ONCE BEFORE THIS TIME IS WHAT WORSE. MY CAR IS LEAKING FROM SOMEWHERE & ITS COMING ON THE INSIDE. MY CARPETS ARE CONSTANTLY WET, MY AIRBAGS ALONGSIDE WINDSHIELD LEAK, AND THE HANDLE WHERE YOU OPEN THE HOOD OF THE CAR IS LITERALLY A STREAM OF WATER ENTERING THE CAR DURING HEAVY RAINFALL. THE AIRBAG LIGHT HAS COME ON AND THE CHECK ENGINE. I WAS MORE CONCERNED WITH THE CHECK ENGINE LIGHT SO I WENT AND GOT IT CHECKED. THE CODE CAME UP AS U0155 - WHICH REFERS TO (LOST COMMUNICATION WITH INSTRUMENT PANEL CLUSTER (IPC) CONTROL MODULE) MEANING MY ENTIRE DASHBOARD NEEDS TO BE REPLACED BECAUSE OF THIS LEAKING ! I HAVE TAKEN MY CAR ON MULTIPLE OCCASIONS TO VW DEALERSHIP FOR SERVICING (NEVER FOR THIS PROBLEM) AND THEY NEVER ONCE TOLD ME ANYTHING ABOUT CLEANING THE SUNROOF DRAINS EVERY TWO YEARS AS MAINTENANCE, IT IS VISIBLE TO THE NAKED EYE THAT MY SUNROOF IS MESSED UP BECAUSE WHEN I PURCHASED IT THE LINING ON THE CAR AROUND THE SUNROOF IS DROOPING AND I CANNOT OPEN THE SUNROOF BECAUSE OF THIS. I NEVER THOUGHT OF IT AS A BIG DEAL BECAUSE I DON'T USE A SUNROOF BUT HOW WAS I SUPPOSED TO KNOW THERE WAS A LEAK WITHOUT ANYONE TELLING ME THAT WAS EVEN POSSIBLE. I LOOKED UP THIS PROBLEM ONLINE, THAT'S HOW I KNOW WHAT'S WRONG WITH MY CAR. I REFUSE TO GET IT "DIAGNOSED" AND SPEND OVER 200$ ON JUST A DIAGNOSIS WHEN I ALREADY KNOW WHAT THE PROBLEM IS AND THEY'LL END UP CHARGING WAY MORE TO ACTUALLY FIX THE PROBLEM. THIS IS MY FIRST CAR AND I DON'T KNOW MUCH OF ANYTHING ABOUT CARS EXCEPT KEEPING UP WITH OIL AND FILTER CHANGES, FUEL INJECTORS, AND CHANGING MY TIRES WHEN THE TREAD IS GETTING LOW. I HAVE DONE ALL OF THAT AT EACH CHECKPOINT SINCE I PURCHASED AT 63,000 MILES. THERE IS SO MUCH CONDENSATION INSIDE I CAN BARELY SEE OUT MY WINDOWS, I HAVE SIT FOR AT LEAST A HALF HOUR CAR ON TO BE ABLE TO SEE & DRIVE.
