Hello to everyone!
I bought my Octavia mk3 2014 2.0 with 150.000 km in November. When I went to check it, engine was totally cold, and sound was normal for cold engine. After test drive it was 90C heated and again no weird sounds. About less than month ago I noticed that rattle sound like is described previously in this topic, and it is always like you said between 50-80C. Not when it is totally cold, but with heating to 90C it goes away.
I am just wonder, did any of you find some solution for this problem? As you told that changing of pump did not solve or it happened again. Also I see, someone said after +50k km it is same, but it is really annoying for listening outside for that "tak, tak, tak, tak..."
If anyone solved meanwhile please let me know.
Thanks!
