Hello everyone , I’m new here and appreciate any help I could get from you guys.

so I have recently purchased a nice Volvo S40 in a mint condition , accident free all original paint , however , recently have discovered that my DMF and clutch are due to be replaced because of rattling noise when I press the clutch and DMF knock and rpm drop when I come to a stop at a traffic light :/ real bummer .

However I already booked a repair with a mechanic so will get both the clutch and DMF replaced in 2 weeks. However there is another issue with this car that bothers me
There is a weird ticking noise on idle . I don’t know if this is normal or if this is valve or injector or anything else . It’s a 2010 s40 with 128 000 kms on it and bad flywheel . What do you guys think it Is? Could the flywheel cause this noise too ? Link is below
