2006 Volkswagen Phaeton

VEHICLE IS AT 80,000 MILES. THERE IS A COOLANT HOSE WITHIN THE VEHICLE THAT CONNECTS THE OIL FILTER RESERVOIR TO THE ENGINE BLOCK. THE HOSE IS MADE OF PLASTIC AND CRACKS IF ANY OF THE MANY FACTORS ARE MET (RAPID CHANGE IN TEMPERATURE, HIGH COOLANT TEMPERATURE, OVER 75,000 MILES). AS A CONSEQUENCE, THE PLASTIC CRACKS AND COOLANT RAPIDLY SEEPS OUT OVER TIME. AFTER READING OVER MANY FORUMS, THIS ENGINE, THE VOLKSWAGEN/ AUDI 4.2L V8 HAS HAD THIS PROBLEM FOR DECADES. AND MANY COMPLAINTS HAVE BEEN SPOKEN OF THE PART FAILING AROUND 75,000 MILES (NOT LONG AFTER THE WARRANTY EXPIRES). IN ADDITION, THE REPAIR TO FIX THE $6 PLASTIC HOSE REQUIRES A FULL ENGINE DROP FROM THE VEHICLE RESULTING IN A VERY COSTLY (I WAS QUOTED $2600) REPAIR. I WAS SPEAKING WITH AN AUDI PARTS DEPARTMENT, AND THEY STATE THIS REGULARLY OCCURS. THUS I FIRMLY BELIEVE THIS IS A DESIGN PROBLEM AND IS ACTUALLY EXTREMELY DANGEROUS TO THE ENGINE, THE ENVIRONMENT, AND TO WILDLIFE. WITH A LOSS IN COOLANT, AIR ALSO SEEPS INTO THE COOLANT SYSTEM. THUS THE ENGINE MAY OVERHEAT (MINE LIKE MANY OTHERS HAVE) DUE TO A LACK OF COOLANT CIRCULATION. HOWEVER IN THE PROCESS, THE COOLANT RESERVOIR MAY STILL APPEAR FULL AS THE AIR POCKET IS TRAPPED WITHIN THE SYSTEM (THUS NOT SETTING OFF LOW COOLANT WARNINGS AND NOT LETTING THE OWNER TO INSERT MORE COOLANT) WITH AN OVERHEATING ENGINE, THIS LEADS TO A HIGH CONCERN FOR SAFETY. IN ADDITION, THE FACT THAT COOLANT IS CREATING HALF-GALLON PUDDLES AROUND MY VEHICLE AFTER EACH DAY OF WORK IS ALSO A LARGE ENVIRONMENTAL CONCERN (NOT ONLY THAT, ETHYLENE GLYCOL WHICH IS THE MAIN INGREDIENT OF MOST COOLANT MIXTURES ATTRACTS WILDLIFE AS IT IS SWEET IN TASTE AND CAUSES DEATH AS THE MIXTURE IS INCREDIBLY POISONOUS). *TR
