Fuel pump while driving home after a road trip on the highway (in the left fast lane) my car suddenly lost power and would not accelerate when pressing on the accelerator. the "ecp" warning light came on and i had to ease the car to a stop on the left shoulder. after about 5+ minutes, i was able to start the car again and move it over to the right-hand lane when the car stuttered and shut off again. this time i was on the right shoulder. after another few minutes, i was able to start the car again and called ahead to take it in the nearest audi dealership (in the town i was returning home from). the car had seemed a little hesitant to start. the next day (just before closing), that audi dealership's diagnostic tests determined the error code to be '2043758/8 punch 2 & 3' which required replacement of the fuel pump. four parts needed: fuel pump, cap, washer and 'repair set'. since this dealership couldn't explain what the 'repair set' was needed for - the most expensive part - i called other audi dealerships and searched the internet for information. no other source mentioned a 'repair set'. also, all but one other parts department said that the fuel pump part was backordered by 1-2 weeks due to many recent issues with the this part. since it seemed that i was being taken advantage of by that first dealership, i purchased the 3 parts (pump, cap & washer) at the only audi dealership that seemed to have the pump (about an hour away from my home town) and made a service appointment at another dealership near the town i was visiting. a convoluted process to get my q5 fixed but due to the number of reported issues with the fuel pump according to the audi mechanic, there is a problem with the audi fuel pump in addition to fuel pump flange recall.
Particulate sensor (particle sensor lambda dpf diesel audi a4 b9 a6 a7 a8 q5 q7 4g0906261b) in the diesel particulate filter (dpf) filter failed at 56k miles, 4 years into the life of this vehicle. this is a $500 (aprox) part, and it is related to the diesel emissions control system, which is not yet patched under the vw tdi program. i am being told by the service that i cannot drive this car until sensor is replaced, and there is no warranty coverage.
Drove on hawthorne boulevard close to torrance boulevard less than a mile away from audi dealership when the car start to shake and almost got rear ended. i was able to pull aside and after few seconds the engine was working fine but a message on the board mentioning the auto stop start function was not working properly and the associated symbol turned on the dash. i took the car to audi dealership and they confirm that the fuel pump needs to be replaced. *tr
Fuel tank leak. went for a normal uneventful drive from howard county maryland to virginia suburbs and came home back and parked in the garage on friday the 13th!. woke up in the morning to a garage that smelled very heavily like gas. looked below the audi q5 and saw a small puddle of gas. parked the car outside the garage and called the dealership. they advised that this could be a safety hazard and asked to call audi roadside assistance for a tow to the dealership. audi roadside assistance asked me to call the local fire department to make sure it is not a fire hazard. the vehicle was then towed after the local fire dept. made sure this is not a fire hazard while being towed. the dealership called me today (monday the 16th of july 2014) to tell me that the gas tank was hit by some road debris and also mentioned that there are some scratches in the fuel tank and was not sure why the leak is occurring. even though the brand new q5 is just 2 weeks old, the repairs will not be covered under warranty and its approx. $5,000 to fix the issue. i have called audi customer service and waiting to hear from them at this time. i'm also filing the complaint here since this issue seems like a significant safety concern. how could a leisurely uneventful drive in a brand new suv on the freeway lead to the fuel tank being ruptured or cracked from road debris! this just does not seem right. since it was parked overnight in a closed garage i was able to find the issue. i'm worried that there may be others parked in the road that may not find the issue and could cause a fire while on the move or it could burn down the house if parked in a closed garage for extended period of time. *tr
