I have a 2014 Octavia estate SE with 4wd. I’ve been advised that the rear diff needs replacing as there is lots if bearing noise coming from it. I’m trying to find a suitable second hand rear differential and wandered if anyone knows which other models have matching units?

 

many Thanks 

Welcome to the forum.

@J.R.might be able to help with advice.

He has a Yeti but there was similar posts asking about diffs in the Yeti section where members had failures.

Getting more and more comom just had mine replaced .if you are replacing diff make sure they carry out pup Lean on Delphi or genuine vcds 

Hi, can you confirm what needs to be carried out? Not sure what was meant by Pup Lean on Delphi or genuine vcds? Many thanks 

What I ment was pump learn if you change pump or change oil in haldex u must carry out pump Learn . Pump learn this is done true diagnostic software the pump runs at difrent speeds on and off for 3 mins or so this adaptation is yoused to properly control oil flow .I have found some software do not complete this adaption properly    

Ah, ok, understood. Thanks 

Was there much filings in diff oil If not it may be wort cleaning pump and doing pump learn as if pump has incorrect adaptation rear diff car remain on and can cause a whine or a feeling like your driving over some thing over and over agen at low speed

 

have have attached a file from another forum that goes true working of the unit
