335d squeaking/farting pump noise (video)

stiritup · 11-16-2020, 10:56 AM

Hi all,

My 335d has been sat most of the year due to the current conditions, but the few times it's been driven, it has been making quite a noisy farting / squeaking noise from a pump somewhere. Seems intermittent and varies in volume.

Has recently been serviced and the mechanic didn't recognise the noise.

The car is running fine, just quite annoying and a bit embarrassing as it's fairly loud in person.

Has anyone come across the same issue?

Youtube link.

Thanks in advance

Update. AKA 'duck noise'.

Looks like its the EGR pressure convertor.
