Yeti rear Diff - which one?

[lippy427]

Hi All,

 

Rear diff has just failed on our Yeti (it had been making a noise for quite some time, so not unexpected).
I'm trying to find a second hand replacement, but not sure how 'universal' the rear diff is...

Yeti is a 2013/13, 6 speed manual, 2.0 TDI CR(170bhp)

 

Does anyone know if I need a diff off of the exact same model or is the diff on a DSG version or one of the other 2.0 TDI variants the same?

 

Cheers
Geoff

It is the diff and not just the Haldex?

 

Maybe @J.R.can help you on what has what diff wise.

Cheers Toot - definitely the rear diff I'm afraid.

 

There's a few on ebay - but some of the listings / part numbers seem a bit confusing, so not sure what part number I need.

Car is at the garage - so may have to get on to them to have a look for me .

 

Any help gratefully received @J.R.if you are abld to assist.

 

Cheers

TMB ME7 5L 7 D 6 061167

[Crasher]

The full unit code is KMC, new unit part number 0BR 525 010 G and £5164.80…🤑

[lippy427]

thanks for that - looks like I need to keep on looking, so far have only seen second hand 010E & 010G for sale.

Have you looked into having your original diff reconditioned?    For example - https://www.mandttransmissions.co.uk/reconditioned-differentials.html.       https://www.thedifferential.co.uk

If it has failed as a result of the wrong oil being drained during a Haldex service then it will be pretty much unrepairable unless the person stopped driving at the very first tiny signs of noise, I did so and have been in remission for 3 years but its damaged , noisy and at best in remission, it willsurely  fail before I am ready to part with the vehicle.

 

Lippy 427, to my knowledge there is very little if any difference between the various part numbers, the ratios are the same for all vehicles, unlike the front diff or a RWD diff which would have differing ratios according to power plant wheel size etc the rear diff ratio has to match that of the transfer box and that I believe has remained constant.

 

The differences in part number suffix I believe relate to the Haldex controller which surely must be included for £5164!

 

When I was looking I only wanted the diff and not the controller, I just missed on one at £200 that had hung around for a long time, the others were £3-£400, that was 3 years ago now, lots have failed since so the price may have risen.

I don't think you risk getting a bad one from a breaker, only someone dodgy selling their old failed one, aside from an incompetent lack of lubricant I think they are bulletproof and will easily last the life of the vehicle. When this incompetent drained his diff oil believing it to be Haldex fluid what came out was a clean as the day it was filled in the factory 79000 miles before, that can't be said for the carbonised the dribbles that came out 200 unlubricated miles later or the diff oil put in for 20 miles to flush out any other contaminants.

 

I must do them both again soon and see how both the diff and Haldex are holding up.

MandT are a decent bunch...   They are only about 10 minutes walk from me and I've used them quite a lot over the last 10 years or so for tyre changes, MOTs and servicing. 

 

They may not look like much from the outside but know their stuff and charge reasonable prices. 

[Crasher]

Remind me Monday and I can check which other VAG models it was used in, that could make the search easier.

[J.R.]

I believe that when I was looking the diff was common to all the VAG FWD derived 4x4 vehicles with the angle drive gearbox on the front driveshaft.

 

If anything was to be different I imagine it would be the Audi TT or some sporting models.

Hi, thanks for the replies (only just had the chance to catch up...)

 

Re having it reconditioned - it had been whining for about a year before failing - and it when it did fail it was with a terrible grinding noise and it felt like it was seizing up when taking it off the trailer at the garage - so doubt that there's much left to recondition (but thanks for the tip).

 

@J.R.how sure are you that the diffs have the same ratio and that it's the Haldex that makes the difference to the part No. (i.e. with a different suffix)?

The Yeti is currently with a German car specialist (BMW, Merc, VW & Audi - so also Skoda) and they have told me it needs a diff from the same spec vehicle and that one from a DSG model wouldn't fit - happy to go back and discuss the option of them swapping the haldex from our car to a diff from a DSG yeti if that is a possibility. 

 

@Crasherif you could let me know what other VAG models had the same diff - or if @J.R.is correct with respect to the part No. / Haldex, that would really be appreciated.

 

Thanks all - will keep you all updated.

 

P.S. in my earlier mail I stated that I had "only seen second hand 010E & 010G " - what I meant to type was "010E & 010B" - have yet to find a 010G diff anywhere (though I do have a couple of quotes for second hand diffs (not confirmed if part No. 010G) from www.partsgateway.co.uk for over £1K !!)

It is used in certain versions of the TT from 2013 to 2014 with the code PYG, 2010>2015 Altea 4+ with the code KMC and MMK and 2014/15 Superb 4M with no code listed. Of interest is the earlier unit 0BR 525 010 B changes to a G anyway and this is used in A3, TT, Octavia, Golf, Yeti 2007>2015 and even back as 2004 as the KMC with the original part number 0BR 525 010.

[J.R.]

The DSG gearbox may have a different transfer drive ration but ias it is effectvely an outrigger of the differential straddling the driveshaft I cery much doubt it.

 

Design for Pruducrion is all about rationalisation & minimisibg the variants of parts.

 

The garage do not knpw and are being lazy in playing safe, they also want to maximise profits by fitting a new VAG unit and minimising their risk, I would (and did) make it ùy business to find out the exact differences in the suffix numbers, whether it is a revision and for what, I'm sorry I cant do it for you but I am close to nlind at present and cannot see what I typz.

Thanks for the replies guys.

 

The garage is an independent that I've been using for the past 20+ years, so I know the owner well. He's basically said that it's not sensible cost wise to fit a brand new unit and has suggested that the cheapest option would be for me to track down a second hand unit that they will fit (he has also mentioned that he uses a gearbox / diff specialist that maybe able to refurb, but would need to open it up first to see the damage)

 

@J.R.I've been trying to find out what the suffix numbers mean, but have drawn a blank - if you could give some pointers as to where to look that would be appreciated.

As you say, I'm sure that Skoda (& Audi & VW) would want to use the same part as much as possible.

 

Will have another chat to the garage tomorrow (see if he can get me the part number of the unit on the vehicle and if he could explain what the suffixes mean).

 

Cheers
Geoff

Deep sympathy...best wishes

Thanks it will pass, my ophtalmo is back on Monday.

 

I'm pretty sure its an allergic reaction to pollen combined with being 20 days post operatoire for a cataracte op.

 

There is also a secondary cataract growing which I expected and hence is not of concern.

 

I could just about see that so I dont think there are any typos, yesterady was a very high pollen day other days its worse in the mornings but never good.
