Thermostat OEM Audi or OEM Volkswagen
Reviews
I've got a 13 sport with 135k miles on it. Only ever done oil changes, spark plugs, 12v battery and a thermostat. Other than that it’s been stupid reliable.
Pros: stupid reliable
Vehicle:
Volkswagen Touareg
Mileage: 217261 km
Not the water pump but I just had my thermostat replaced under the extended warranty. I was slowly losing coolant with no discernable leak.
Pros: fully covered, extended warranty
Cons: slowly losing coolant
I just got this done and Audi quoted me $2500 for just the thermostat. Mine was covered by the extended warranty Audi has on all water pumps leaks.
Pros: covered by warranty
Cons: expensive repair
Vehicle:
Audi A3
the 80c has been running flawless. Only difference is that my coolant stays at 83-94c. It used to get as high as 100 sometimes. Also the 80c part was recommended oe part #
Pros: running flawless, lower coolant temperature
Vehicle:
Audi TT
Part number: 050-121-113-B

Noticed coolant was low and could smell it sometimes. Dealership pressure tested system and found coolant leak at thermostat housing. Thermostat replaced under warranty. Its probably been leaking slowly for a year or more.
Pros: replaced under warranty
Cons: coolant leak, slow leak
Vehicle:
Volkswagen Golf
Mileage: 27199 km
My Q5 with 75,000 miles on it developed a leak in the water pump area. Initially Audi denied there was a leak, so I took pictures and showed it to them. Then they diagnosed it with thermostat leak.
Pros: warranty on that part
Cons: leak in water pump
Vehicle:
Audi Q5
Mileage: 75000 km
Sounds like your water pump is working, but maybe your thermostat is stuck closed? Have you tested the thermostat?
Pros: water pump working
Cons: thermostat stuck closed
Vehicle:
Volkswagen Golf
mine is also a problem an my car is 1.5 yrs old. Sometimes the temp gauge acts as if it is -40C outside even if it is a couple degrees above freezing. Often the car will take 4-5minutes to get near base idle when it is cool outside, but when it's really cold, sometimes it takes 30seconds and there is no way it's warmed up. Can also smell coolant anytime I open the hood. Sad.
Cons: faulty temp gauge reading, smell of coolant
I had my water pump and thermostat changed in August under warranty. I went for an oil change in Dec and they told me they think the thermostat is leaking. I told them they just replaced it 4 months ago. They went back and cleaned up the area around the thermostat and oil pan and said we need to monitor it to see if it's really leaking again. They were not surprised when I asked if it was possible it could be leaking again. They told me they see the part fail all the time.
Cons: leaking again after 4 months, part fails all the time
