Alko anti-sway and DSC

[stewmair]

Wheeling downhill at 90kph pulling a 22'6" Pamplona caravan which has Alko anti-sway I was buffeted by a passing B double. The van started to sway then the DSC started a mighty battle with the Alko anti-sway that almost tore the steering wheel out of the hands.
Eventually managed to stop but next time I will be ready to turn off the DSC.

Id be turning off the vans version.

which way was the truck going?
(mine only ever sways by overtaking trucks)

why not switch off the Alko?

Have you raised this with Alko?

I asked them a while back about the potential of the 2 systems fighting each other. Seems it can happen.

I would turn off the ALKO system and use the LR system only.

Turning "off" the DSC (which only really de-sensitises it) won't disable the trailer stability assist. You'd be better turning off the Alko until they figure out how to make it work with car systems.

This is interesting and i feared conflict between the D4 and caravan ESC when i purchased our 21 foot van. We have done over 25,000 kms around Australia and i never once noticed the caravan or car esc kick in.

I normally stick to a maximum speed of about 100kmh and often a bit below that.

How fast were you going when this happened? Was the downhill steep and were you already on the brakes as the truck passed?

I am wondering what could trigger what happened to you. Its not something i want to experience!

I was travelling on a moderate decline at 90 kph as stated. MY 07 D3 does not have anti-sway, only DSC. You cannot turn off the Alko system or tow without the anti-sway bar down.

Your D3 has Dynamic Stability Control and Trailer Stability Assist, which is in the old term is(anti sway) all Discovery 3, 4 and RRSs have it and you can't turn TSA off, only DSC, but as said doesn't fully turn off.

Funny that, everything I have ever read about TSA stated that it came in on the D4...

TSA is an extension of the DSC algorithms - the D4 will react faster to a sway condition than a D3, but the D3 is still capable of controlling dangerous caravan sway.

Having said that, none of these systems are "magic" - there are always conditions they can't control, and the driver still needs to be cognizant of the large lump attached at the back!
