Title: Any ideas ? thumping noise when engine is off ??
Post by: simonpolly on 02 July 2009, 18:02

My 2.0 ltr fsi touran(on only two occasions),when we have stopped and turned off the engine there has been a banging noise,a steady rythm it sounds like a thumping noise and lasted for about 30 secs.Any ideas ? Engine is switched off,car is low mileage and in good nick :undecided:

Like someone lightly thumping on something not banging,only happened twice so can`t really tell where from,happened today and about 2 months ago,almost like someone is locked  under the bonnet and is tapping to get out,in a perfect rythm .(and no before anyone says it  :grin:)

Might be an aux water pump or valve shutting down.

Maybe ,its going for air con service on monday and cam belt which it is due,its very odd because the engine is off,and this noise carrys on then just stops,it does not slow down,just stops,its not a grinding or metal banging noise ,very odd.

my car makes a ticking noise when you turn the engine off after driving her hard, its just the metal cooling down

Most cars do,no this is really strange,sounds like somone was thumping to get out in a perfect rythym for about 30 sec then stopped dead :undecided:

cooling fan perhaps?

Or as suggested, various control units powering down? Ford focus' do this when you switch them off, it actually sounds like a generator has turned off.

Although it does depend on the volume of the thumping.

maybe,its had cam belt and kit,so nothing serious,but strange,i know mechanical problem noises fairly well but this was different,only done it twice.
