Octavia mk3 rear differential problems

[BillDa]

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.

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
