Service no.4 was due this week so I asked the the dealership to check the pressure while it was in. The DRC had never been touched since it left the factory five years ago, so (as per above topic) I assumed it would be a little down on pressure. The workshop manager advised me that I'd probably lose half a bar by measuring it - which he was happy to do - but suggested a full drain, flush and recharge would be a better idea.
The car was left in early so they managed to do the job by closing the same day, rather than keep the car overnight.
It turns out the pressure wasn't low at all - 13.5bar. I was hoping for a low pressure to explain away my handling worries. The final pressure post recharge was 15.5. Now that doesn't seem like much of a difference on paper to me but subjectively the car is feeling much better! The car's posture through tight cornering is much tighter and any lurch of the front corners when the car's weight is thrown at them is reduced. It's too early to say if the sensitivity to tyre pressures is cured but I'm optimistic.
So, what does everyone think? Could the DRC pressure increase from 13.5 to (edit) 15.5 be responsible? Is there something in the way a drainage, flush and recharge is done that might reset/correct damping issues?
...or is it all in my head?!
By the way, hats off to Tyneside Audi. We've had our run ins but everyone seemed to know what they were doing today. Would recommend.
