I am experiencing exactly the same mysterious coolant loss (5mm drop in expansion tank after 3000km). I found it a year after the replacement of faulty water pump at 40k on a dashboard once I got low coolant warning light. Took the car to the dealer garage, they put the system under pressure but haven't found any visible leakage so they just topped the coolant and told me to monitor the level. Also, it seems that the water pump is working fine, it's totally new and was replaced in warranty with original part. So in case it is EGR cooler leakage, could it be detected somehow outside the cooler? @Nygaard did you manage to solve it?

It seems that rattling is caused by the vacuum oil pump until oil temperature reaches 60 degrees. Skoda declares it as a normal behavior caused by the engine construction. I found it's a common noise also experienced by the other owners of Skoda 2.0 TDI engine, you can find more details in this thread:

Yeah, it is strange also that once the engine gets warmed that rattling dissapears. I guess it has something with the belts. Also I need to check additionaly this coolant loss as there are no visible signs of leakage but I know there is a small leak somewhere. I guess that garage did only basic check using the pressure so I need to ask them to do the detail inspection (e.g. to check water pump, EGR cooler etc.)

I noticed strange rattling sound coming from from the engine upon a cold start and after some time sound disappears. It looks like it's coming from belts or water pump which was replaced 20.000km ago at 40.000km. The pump is working fine after the replacement even though I noticed certain coolant leakage (let's say 5mm of coolant level dropped during last 3.000km) without any visible trace. Even my dealership garage didn't found any leakage by putting the cooling system under the pressure. I am driving Skoda Superb 2.0 TDI DSG from 2019 currently with 60.000km on the dashboard. Here you can find the rattling sound from the engine: Did someone experienced the same noise or might have a clue what's going on?

Hi, Guys from carwash removed my interior mirror from my Octavia mkII but they couldn't attach it back, so they let me do that I tried to attach it back but I'm afraid if I push it too hard and maybe break something (interior mirror or even windscreen). Is there any catch to do that or I just must push it hard?
