Diff for 01 bora 4 mo

[Coralon]

OK - so i'll ask the guys to check for any error codes codes and then ask them if it could be the diff oil/fluid (supposedly lifetime guaranteed) or the Haldex fluid (every 60,000km).

Life time is the life of the manufacturers warrenty, this was 3 years or 100000km for mk4 VW's. Change your diff oil even if your diff is in perfect working order and it has never been done, any good 75w90 gear fluid will do the job and you need a fly sh** over a litre.

I reckon that if you have no whine and you have the bunny-hopping problem that it's haldex unit and not diff.

If the diff (which is a purely mechanical part, no electronics or hydraulics at all) was messed up enough to bunny-hop like that wouldn't it be accompanied by some whine or pretty nasty crunching noises?

Governor which mechanic are you using?

Can I highly recommend you take your car to Canberra VW Centre in Belconnen? The guys there are very knowledgeable and have been nothing but a pleasure to deal.

I suspect they will be able to diagnose your fault quickly for you, and provide a quote to fix the problem.

Hope this helps

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.

yeah, I take it to CVWC in Belconnen, Deane and Peter pretty good. Taking it there tomorrow.

jpflorez, you need a new mechanic

Thank God it's actually not my usual mechanic. I just found his name listed on this forum as someone who previously fixed the problem for another member and called him up. Honestly he's the only one I called up as I'm not the one who'll pay (hopefully) because it's still the dealer's responsibility under warranty.

At least now I know it's way more affordable to fix if the dealer does screw me over! But I've got Consumer Affairs on my side and they deal with the dealer on behalf of the dealee.

just picked up the car this arvo. I didn't follow everything he said, but sounded like the ? clutch-pack was sticking to something on the diff. So they tried 'un-sticking' it. Gonna drive it for a bit then let them know how it works out. Still did a bit of a bunny hop on the way out of their driveway, but I tried a reverse turn and it seemed OK.

will report more later

[governor22]

well, after a few U-turns last night and some more reversing around quiet streets, seems like the problem is still there. Guess I'll start saving for a diff

[vert1]

Most likely your haldex clutch packs are fried, most times its the Haldex controller that fails which engages and dis engages the clutch packs all the time in turn burning them up and thats why the car binds on turns.
I haven't taken one apart yet but surely there must be clutch sets avaliable in Europe or pommyland?

I'd like to see inside one too!
