Had my haldex [gen 5] oil changed 1000 miles ago, maybe 500 miles ago noise from the back end...sounds diffy.... Do they have to be done together, I assume theyre different units...meaning draining the haldex does not drain the diff.

The noise get's louder when warmed up, plus theres a road speed link...meaning wheel rotation speed.

I made a recording using phone in the boot, theres a delay getting in/out of the car, the click you hear is when changing gear...which you can't hear in the drivers seat.

Its a 2014 Tour De France model [4x4] made for 100 yrs of tour de france.

Hi, def sounds diffy to me too :-(

They drained the diff oil by mistake and then topped up the Haldex with a lot less fluid than it should have taken, that should have alerted them to their mistake.

You are running around with a dry differential, take it somewhere else for inspection do not take it back to them as they will trot out all the reasons why you will have to pay the £4k or so they or anyone else will want to replace the damaged diff.

Do not continue driving the car as you risk it grinding to a halt as has happened to many others who conferred their vehicle to a garage for Haldex servicing.

Strangely the guy who ones the shop has a VRS as his personal car....but he does have others in the shop. My guess is he didnt check on them

I actually know one of them, just arrived from life of working on Bentleys.

Thanks for the comments, given whats been said Im mightily surprised it's done 500 miles.

Actually plugged diagnostic in a while back....came up with code c111213 ''clutch pump open circuit haldex''...called skoda dealer who told me no such code???

The FSI VRS is FWD so no Haldex or rear diff, does he have an FSI or TDI VRS?

His is not a 4x4, but he does service a lot of vag's

He's done quite a bit of work on mine, always really good, actually collects and returns for me as he lives same village. He's well respected locally, has a 6 weeks lead time just to get in. So busy he stopped doing MOT's couple years back.

I do think one of his guys has done it, not been checked by him tho.

Sadly nearest dealer is nigh on 60 miles away....benefits of living wild's of Wales.

Dogsb, are aware of an alternative meaning of vags? 🤣

I did about 300 miles before I noticed, the last 190 were a high speed motorway then autoroute dash heavily loaded where I first noticed a whine on the over-run, yours is much worse but you have done more miles.

I caught mine just in time, I flushed through twice with oil/paraffin mix driving a few miles each time, the oil coming out was carbonised, it has had a whine ever since but I have a really sympathetic mechanical ear and also drive without rear seats or parcel shelf, I've done 50K miles since and only one other person, a co mechanic from my teenage years has noticed and remarked on it.

Yours sounds terminal TBH.

It will be interesting to hear their excuses to add to the book.
