Audi e-tron bouncing?

[DJMC]

Was following a new one today on slightly undulating tarmac and noticed the rear was going up and down big time, as if it had no damping whatsoever.

I put it down to the weight of the batteries but could it be the pdi didn't do something which should have been done?

I had a brand new courtesy 718 a few years back which had little suspension movement. They hadn't removed transit blocks.

I've had a similar thought about mine tbh.

It's done 25k miles and until recently I was living down a farm track. I've not long had front bushes replaced because it was creaking like mad.

Makes me wonder if the air suspension is really up to controlling the mass. Another reason I wouldn't want to own one out of warranty (mine is leased and goes back on its 3rd birthday)

Not all models come on adaptive air suspension, only the S-Line an above. Ours has it and can't say I've noticed any bouncing in any of the settings for it we've used.

It's very clever and has 7 different options for ride height/compliance dependent on what kind of surface you are on (allroad, offroad, efficiency, comfort, auto, dynamic, individual) so possible that even if that car was fitted with it the setting used was unsuited to the task.

ETA - Just thinking, was it a FF etron or a Q4 etron? I've heard bad things about the suspension on the Q4.

I think it read GT after the e-tron?

Ah, OK, it'll be one of these then.



Not driven one so can't comment but not heard about ride issues as essentially the same underneath as a Taycan.

By very odd coincidence I've also just seen one, which is a very rare event.

Check your tyre pressures. My Model 3 became VERY erratic at motorway speeds after having new rear tyres fitted. They overfilled them by 3psi and it made a huge negative difference! Once back to the correct pressure normal ride ensued.

Tesla sensor reports negative pressure not positive over-pressure. I can understand why they have done this (likelihood of under pressure) but think it should monitor both!

The Model 3 sensors give a specific pressure readout for all 4 tyres, and an additional 3 psi would be considered within spec dependent on load/temp anyway so wouldn't be considered dangerous.

Agreed, you only ever get under pressure alarms/reports/alarms, I guess for the sign of a puncture. In the really hot summer of 2019 in the days before Covid I drove to Italy. 38 deg c outside. Pressure rises as tyres heat up which may be why they don’t alarm but the TPMS were showing over 50 psi, worst was 52 ps, on the drive. At the first stop I dropped them to 48 while hot (the ‘cold’ pressure is meant to be 42 and in use I’d normally never see them go above 47 so I thought a little high but better to be safe. The ride improved a lot. I think a lot of people only ever top them up when low as the weather cools, but never think to lower them as temperatures increase and the pressure rises. Worth checking regardless.
