528i 1998 touring:

Well i really dont know if this is a normal sound for my 28i engine since i dont know him yet very well...

When on idle, i mean not driving, only engine running, from the car inside i hear some noise i guess it comes from the outside, maybe engine compartment, something like:

ta ta ta ta tra tra ta ta (the "tra tra" means an irregular sound between all "ta ta"....)

Very low sound, need to be focused to hear....

Well since i dont know if this is a normal sound i put here my engine working on the outside and would like to know your opinion if these is a normal engine noise and take a careful look at the end part...where near the engine you could see some vibration...

I have Castrol Longlife 04 0w30 on this engine since almost 2500 kms

Thanks!
