My 2014 VRS 230 fitted with the VW "VAQ" electronic fwd diff hasn't been over impressive.

 

The car has recently been in for a 20k mile service and as part of the diagnosis they found a fault code on the diff, which turned out to be a problem with the Haldex clutch pump not working.

 

The dealer has ordered a new pump under warranty which is due to be fitted soon.

 

I haven't had the car that long and it has covered 4000 miles since the last dealer service, I assume this diff pump issue was never picked up at the service last year so the pump has only recently become ineffective.

 

Please could some one advise on the effects of the pump not pumping sufficient pressure to activate the clutch pack.

 

Is it right to assume the plates would not actually work and would be separated or apart without sufficient oil pressure?

 

I am concerned that damage may have occurred to the clutch pack while driving it around with an ineffective pump?

 

Please could anyone with more knowledge on the Haldex based systems advise if I need to ask the dealer to replace the clutch pack as a consequence of the ack of oil pressure from the Haldex pump?

 

Many thanks! 

Hello and welcome to the forum but I am confused. As far as I know the vRS 230 only became available this year; non 230's do not have an LSD but rather the VAG electronic diff system and Haldex is the 4x4 system? Or am I wrong...?

2015 I do believe

Yep, 2015 for the vrs 230

As far as I have understood it, the diff on the 230 works just like it does on Haldex (4x4) equipped cars. It just lacks the traction on the rear wheels.

It moves the power to the wheel with traction, instead if braking the spinning wheel.

At least I think that its how it works

Tks for the responses which seem to ask more questions than I did? 

 

The car is a very late 2014, so I assume it is a 2015 model year.

 

It is definitely a Fwd fitted with VW's "VAQ" electronic Limited slip differential as fitted to certain models of Golf GTi & Seat Leon.

It does not have or has ever had a 4WD system on the car.

 

Minor details of differential here;

More detail for those with unlimited stamina in an hour long webinar by Borg Warner who make the diff, here;

 

 

Basically, I am trying to find out if a lack of fluid pressure causes damage to clutch plates.

My assumption is they are apart when there is no pressure, so should be ok? 

It is only when the clutch parts make contact that a haldex type diff is effective, which needs oil pressure.

I am hoping the diff has been safe and dormant while the car has been driven with an ineffective pump.

 

Skoda / VW seem to refer to this as Haldex diff in their correspondence.    

I can ask them about potential damage, I know they won't strip the diff down to find out, so I would like to get a little advice on Haldex clutch packs before they fit my new pump.

 

Thanks again!

The Skoda Octavia 230 Vrs went on sale in the UK as of June 2015.

Could you have been sold a clone Campaign ? Your dates just don't add up :-(

I presume this is like a Salisbury, only more "intelligent" and progressive in how it locks? If so, then when the pump is down you're effectively driving a car with an open diff, and no wear to the clutches can occur.
