Bora 4mo ESP kicking in at slow speeds

[kapowww]

Fuse 31 is the definitely the Haldex on the R32.
What size is the Fuse? If it's 20A then it is definitely the Haldex (there should only be one 20A in that section of the fuse area). You should get the lovely little orange triangle with the circle around it on the dash.
If it is indeed your Haldex that is fudged. I'm pretty sure my stock R32 one is still packed up in a box somewhere. PM me if you're interested.
Cheers,

It's a 5A fuse but the orange triangle pops up when it's taken out...

Simply because after 180,000kms of trouble free motoring and knowing every nuance of this vehicle, this fault has only just manifested itself on my vehicle. Like jpflorez I too can stop the issue with a wider turning radius. I would love to get the car up on a hoist and have a good look myself, but am considering taking it to both the dealer & a VW specialist here in Perth to get their opinions.

Fair call 180,000km is not bad, I'd like to know any outcome if you take it to specialist keep us posted. I have noticed this on many bora's with 4 motion and it would be good to get feedback, Like i said i have a feeling that the problem lies within G251 acceleration sensor i dont think that the haldex is "biting" causing the rear wheels to spin at different speeds then causing light to flash i cannot feel anything happening to the rear or wheels don't chirp. I'm also going to test mine using scanner and check all readings if i find something i'll post.

So if my diff is screwed how much would it cost to replace??

Haldex can be expensive, if you could get one from a wrecked car with low km's that may be cheaper but hard to find. Possibly genuine
only option. This thread is really interesting more info from others is needed for comparison's. in the meantime i'll keep looking into it
hopefully get some answers..

Have you tried turning off your ESP?? just wondering!!!

I've experienced very similar issues recently and have yet to have the definitive solution for mine but I'm oh so close. During my testing to replicate the scenarios of crabbing and lurching during tight manoeuvres I've found that in most cases if I dip the clutch slightly a couple of times as I make the turn it seems to take the worst out of it and settle the car down. Not ideal, but it does help in my case. Otherwise I simply remove fuse 31 if I know I've got a bunch of heavy city driving to negotiate.

I'm hoping to swap over my controller temporarily this weekend and hopefully discover that this is the culprit of my woes. I wouldn't be surprised if this is your problem too, it's far more common than I realised when I bought the 4Mo.

All the best, Rossi ; )

Have you tried turning off the esp and testing opreation???

In my car it doesn't seem like it's the haldex.. Feels like it's the rear diff

On 4-wheel drive vehicles fitted with Haldex
viscous coupling, the front and rear wheels are
joined by a rigid coupling. The calculated true
vehicle road speed, which is determined from the
individual speeds, may be too inaccurate under
certain conditions at low coefficients of friction
and when the Haldex viscous coupling is closed.
The longitudinal acceleration measured is used
to verify the calculated vehicle road speed.

This is some data i've found regarding operation of the sensor which i think could be causing these issues
