Hello, everyone.
I need advice please.
MK7 R - 55k miles
On occasions, the vehicle emits a gurgling sound after being turned off after a regular drive, as well as some other sounds, although these do not appear uncommon and are simply the result of typical electrical components/vehicle cooling down.
The extent of a journey makes no difference; it can occur on a short trip of as little as 5 miles or a long journey of 25 miles or more.
The sound is coming from the driver's side of the vehicle. I believe it is related to the coolant reservoir.
I carried out numerous checks:
There is no white or milky smoke (the vehicle has generally had major services, haldex, and DSG from Volkswagen). Another major service was carried out, as well as brake fluid replacement, on February 10th, with no issues noted. Everything is fine with the maintenance list report.
There is no white exhaust smoke unless it is cold, which is due to chemical reaction (condensation).
No loss of power. The vehicle performs as intended. There are no difficulties.
No water or strange odour (I've read online that if the coolant isn't visible, it's being burned and may have a strange odour.)
No overheating. Engine and oil temperature are always within the optimal range. There are no issues to report.
No noticeable damp spots or puddles. There are no white, dried-up water/coolant streaks.
The diagnostic scan returns no codes relevant to the problem and indicates the vehicle to be in good condition.
Coolant needs to be replenished approximately once a month. If driven in race mode, it may operate as a catalyst, necessitating topping up after three weeks roughly.
With frequent coolant top-ups. I am almost positive there is a leak, and the water pump/+ thermostat housing may need to be replaced.
Would you also agree that the car requires a water pump and thermo housing replacement as it is approaching the 60k mark? I understand that water pumps do not have set mileage limitations and can malfunction at any time.
I do not believe it is a head gasket leak for the reasons indicated above.
I've read about air locks and heater cores online. Could that be the cause? (I don't think so; my heaters heat up and blow hot air as they should. Sometimes too hot for my comfort, but then again, it's a performance car that heats up fast and emits a lot of heat).
Or is it purely because it's a performance vehicle and the coolant is running low due to utilisation? Also, I checked the coolant level and reservoir tank after about 5 minutes of shutting off the vehicle, and there is no major buildup of pressure, if any at all.
I need advice please.
