Softening Airsuspension

Own a 2009 T2 V8 with air-suspension - I live in São Paulo (low speed bad asphalt) and just renewed all arms and suspension bushings and new 19" 275 tyres - but my car continues harsh when driving in the city with holes in the asphalt. My compressor is just fine and ride height also according to factory setting 490mm - I also have a Rosstech cable so can enter new suspension settings

When I put the car in COMFORT mode it raises - I presume more pressure and more amplitude - I know that the dampers are dynamic on this car. Was wondering if there is not a TWEAK to soften compression and increase rebound so it will purport a much more soft and comfortable ride

Anyone has experience in tweaking the system with ROssTech coding to make the care super comfortable ?

Pro-Advice appreciated!

Go to the 17 or 18 inch VW rims with non-sport tires. The sidewall flex will do exactly what I think you are looking for. That will be the easiest way.

+1.


I have a second set of 265/65-17 OEM rims and LT tyres and they certainly do give a softer ride (even with LT tyres) than my 20"s.


Best way to solve your issue me thinks especially as you say you drive on bad roads at slow speed..........why have low profiles??

I do not think you will be able to do much ref the air suspension.

As others have said, 17 inch wheels with deeper tyre walls - even going oversize to say 30 inches diameter rather than the standard 29 inches - might be the only way to achieve a slightly smoother ride.

VW Touareg models are as follows:
Generation 1: T1 is model 7LA & facelift T2 is model 7L6
Generation 2: T3 is model 7P5 & facelift T4 is model 7P6
Generation 3: T5 is model CR7 [Not available in "VW Atlas" North America!]

Sorry, I'm going to say the same thing. You will have a softer ride with larger tires and larger sidewalls. Maybe you can sell your current tires and wheels? <shrug>

The comfort mode reduced the damping action, so that is actually the best mode to be in. The sport mode, while lower (and theoretically less air pressure), increases the damping action and will result in a rougher ride compared to comfort mode.

Can I jump in? Sell the 275's and put on 255/55/19. Then adjust tire pressure about 1-2 psi lower. Done.

Cool. Is that what you did and are you liking it?

I test drove a Touareg with 19" tires. I was told in no uncertain terms that the 19" tires were too rough and would equal a divorce.

The compromise was a Touareg with a set of 18" tires.

Yes. But I just did not like 19's for odd size and little tire selection. So I sold them.

Best compromise there is besides dumping the 19's with new tires and going with 17" if he can even find them. All depends on the tire used as well. Moving up to 255/55 will give more cushion. Is it perfect, no. 17 is my choice on this vehicle. 19 is an odd size anyway. If you want bling, you pay with your chipped teeth. 18 is next next choice. My thinking, swap tires for less hassle, if after 255/55 you cannot stand it, move to a new wheel, plain and simple.

I think the V10 is somewhat heavier on the front end than the V8 which may, in fact, help with the compliancy and, therefore, the ride on the oversize tires you have fitted.

VW Touareg models are as follows:
Generation 1: T1 is model 7LA & facelift T2 is model 7L6
Generation 2: T3 is model 7P5 & facelift T4 is model 7P6
Generation 3: T5 is model CR7 [Not available in "VW Atlas" North America!]
