Diff for 01 bora 4 mo

**governor22** · 13-09-2011, 10:35 AM

My bora has been making horrible clicking noises when reverse parking and doing sharp turns / ESP comes on / and it 'skids' does a sort of 'bunny hop'.

Mechanic says it needs a new rear diff. Or at least the pump in the diff might need looking at.

How much (roughly) would this set me back ? The mechanic said he might be able to use the diff from an Audi S3 in mine. Would that be OK or is Bora specific diff better?

I am clueless, need knowledged people to help.

cheers

You need to get it scanned with VCDS and prove the fault before spending money or speculating on a fix. Find a VW specialist first.

This problem didn't show up on a VCDS scan unfortunately for me. It would have been a lot easier if it did..

Diff then by the sounds of things. Not sure if G60JAY up here in Brissy has one. I was in his shed the other weekend and pretty sure he had a back end to match a 6 speed 4wd transmission he had.

Sorry to be pedantic, but I see this a lot in these discussions and I think the ambiguity is damaging. The Haldex viscous coupling unit appears to be what you are talking about, it is definitely not a diff, it is a viscous coupling and is a separate unit from the diff (though it does bolt onto the diff).

I think one of the major problems in these discussions is some people who know the difference (including lots of mechanics) refer to the Haldex viscous coupling as a "diff" which confuses those who don't know the difference.

This is true, after reading that the mechanic had scanned it. I assumed the diff diagnosis to be correct.

Either way the Haldex and diff would be still bolted together most likely.

Try G60JAY anyway.

2600 is just not going to happen. i just don't have that kind of money atm

is a 'haldex viscous coupling' a smaller job compared to the diff ? would it be cheaper ?

Got the same problem man (actually several people do) and it's most likely the diff. If the Haldex isn't serviced every 60,000km this usually happens. I rang up a mechanic who's done this twice before and to replace the diff with a second hand one, replace oil and filter, etc it cost $2600.

You can keep running your car like this and it won't get any worse, just annoying and it'll chew your tyres a bit more. It may also put more stress on other parts but you just have to turn wider and quicker.

That's more than I paid for a rear Peloquin diff from the states, landed and installed

Someone is having a lend of you for a used one at that price.
