Hi techy folk

While the suspesion system appears to be the same on all models of Yeti, does anybody know if the springs and dampers are different between models, eg between 2WD and 4WD?

Just curious.

For sure, the brakes on the 170 HP diesel are larger than the other diesel models. If the 1.8 TSI share the same brakes, I do not know, but one might assume so, as their speed potential is about the same.

I would imagine the springs and dampers have different ratings, as the lighter petrols carry less weight than the heavier 4wd diesels but have the same payload. So overall max weight varies. That would have to be compensated by spring and damper rates.

Sadly (and unbelievably to me!) the 1.8TSi runs the 288mm disks as standard - the same as the 140bhp TDi not the 170 model. :(

Yes but the 1,8 TSI's engine weighs a lot less than a diesel lump so I imagine there is less weight transfer onto the front wheels when you brake vs the 170? Hence it does not need TDI brakes.

Interesting comments about the brakes, but what about the springs and dampers fellas?

Johann,The different diesel lumps all weigh the same - identical blocks etc. The 140 version also has the same gearbox, so the only possible weight difference would be the turbo size - cannot be a significanrt weight difference. Yet (sic) the 140 TDI has smaller brakes than the 170.

I doubt that the smaller front brakes are marginally sized, but the brakes on the 170 are defiitely more than adequate for the vehicle.

Nothing wrong with my disk brakes, even if the are 288mm :yes:

I think that the brakes, disks, springs, struts, torsion beams for the yetis are good enuff to cope with the 'stresses & strains' of normal 'Yeti-ing'. :yes:

They will be matched to the weight of the base vehicle as all have the same payload. ie, heavier once will have higher rated spings/dampers.

I was hoping that they would be the same, so that mine had a slightly softer ride. Never mind.

Might just have to run with 16" wheels all year round instead of 17" wheels.

I think you'll only get the exact specs of the springs/dampers if you have access to the full parts catalogue. I can't find any more detail online.

The unladen weight of the 1.8 TSI is 30KG less than the 2.0 TDI (170hp), so I would expect there to be a small difference in spring stiffness and damper rate to account for that.

Id be very surprised if less than half the weight of the average adult weight meant VAG produced two different setups between these two models. Every day is a school day though....

Im sure I remember reading that the 1.8TSi had a different front anti roll bar (think it was just 1mm thicker) compared to the diesles but again we'd need someone with access to the parts software to confirm this I guess. Personally, I cant think why it would be thicker on something with a slightly lighter engine (compared to the diesels).

The 1.8 TSI front springs have two magenta paint marks on them - the colour code should identify the spring.

(Sorry about the crap image - had to photoshop a cameraphone pic to get the colour to show properly)

If anyone cares, then look under the wheelarch of a diesel Yeti and see if you have the same marks - if your marks are the same then your springs are the same :-)

Well, I cannot provide a definitive answer to your question re suspension although I can comment on wheels size. I also was concerned about ride quality on the 17" wheels when I road tested a 140 DSG a couple of weeks back and reported same on this forum ( A thread on ride quality assessment between 16" and 17" wheels) I actually said I was disappointed with the ride quality. A week later I tested the 170 also on 17" wheels and I felt there was a noticeable, tangible difference for the better in the way it handled potholes. Of course it may have been something as simple as the 170 had the tyre pressure 1 or 2 PSI lower, or the 170 has a different suspension tune, or it was shod with different tyres, or the mileage had eased the suspension up....in short in my brief experience even two 17" wheels can provide a different quality ride and it's down to a number of factors. This may help to explain why there is no definitive answer to the 16" or 17" question. You're more likely to find a cushy ride on 16" but it's not a guarantee. Fortunately the 170 impressed me sufficiently to buy one (Friday).

For what it's worth, the front springs on our 1.2 have two pink and two grey paint marks on them.
