Hi, my Superb Estate 4x4 has started to make an odd noise very intermittently.  Just very occasionally on a journey is makes a noise which sounds like a Crow cawwing.   The noise comes from the rear and I assume (rightly or wrongly) it’s related to the Haldex system.

 

it also a has a very low level whine sometimes when pulling away but it disappears quickly.  I’ll get it into my local garage but just wondering if anyone has had something similar?

 

It has a full Skoda history and had the 4x4 oil changed in January but the noise started about a month ago.  No difference in power, economy or lights on the dash to indicate anything wrong just this weird noise.

I would check to make sure that they havn't drained your diff oil by mistake and left it dry, an easy mistake but one that a garage with a ramp should never make, unfortunately far too many do leaving their customers facing huge repair bills.

 

Crow cawwing does sound like a failing differential having had a few of them over the years does it do it during turns or in a straight line? Does it do it when you accelerate?

Hi,

 

thanks.  It seems to be when I take my foot off the accelerator mainly.  I’ll get it back in the garage asap.  It is under warranty too but regardless it should t cost me (hopefully).

Just for information I have had the car in a local Škoda garage and they found the problem.  A clogged haldex oil filter.

 

despite getting the haldex oil changed regularly as per Skoda schedule the filter has clogged.  The garage say it’s a reusable filter so it doesn’t get changed and just checked at oil changes.
