Is it as straightforward as other cars - three bolts, swap, done. Use the jack under the axle beam to keep it all in check.

Elsawin says to replace all the bolts - never done this on other cars, is it required for Audi or are they being over cautious money spinners?

Any difference between s-line/diesel and other shocks? Always nervous putting your reg into eurocarparts and trusting the results....

thanks
 
Simple job I used trolly Jack and axle stands 2hrs tops both sides, just make sure you get every thing you need ie bump stops incase yours are gone have all necessary tools. There is a difference between sportback which is mines and sline euro parts very good put your reg in just make sure you read all the fitment requirements

You don't usually need to replace bolts, it's not money spinning for the dealer, it's actually a protective process for you & them, as if an bolt used again & that's obviously been under stress for a period, if it snaps & a serious accident or issue occurs, they're possibly liable, now even new bolts snap, but generally don't, so they always state in Elsa to replace certain ones, even if not needed.
 
Thanks for the info. I'm finally getting around to planning this work. I had a look for shocks and noticed a bunch of different part numbers on ekta

I want to fit Sachs as I understand that is the OE supplier. I went on Sachs website and saw the exact same list above, all linking to one Sachs shock - the 315913. That tells me all the above shocks are all the same, but I've read on other models (A4 for example) that the two characters at the end of the part number mean entirely different shocks. Which is right - can I just fit any of the above shocks?
 
Sachs no longer make the shocks that your car came with from the factory, but they have superseded them with another part. I have the new part shocks fitted to my S-Line Sportback Diesel and they're fine.

Thanks, which parts do you have
 
Thanks, I went with the 318202 and they arrived today

I pushed them down manually (like you do) and it was surprisingly easy and I could hear bubbles. Consequent pushes had a fair but more friction but I was still surprised I could compress them by hand - I expected them to be really hard to push given they are damping a 1250kg ish car!
 
I just spoke to Audi regarding the new nuts and bolts, in total £30!!

For ref:
N90648402 x4 - #15
N10628301 x2 - #8
N10106402 x2 - #9
WHT007127 x2 - #13
8J0512041 x2 - also #13. not sure about this one. not in picture they didn't have it in stock so didnt order it. and not included in the £30. its an extra £5 each.

I don't think bolts #15 are subject to much stress given they bolt upwards and the weight of the car sits on the support bearing (#12) so I'll forego those, but will renew #8 and #9 as the damper sits on this bolt. The new dampers already came with #13 the basic nylon locking nut. The other #13 appears to be some sort of castle nut, they are normally low torque so I wont bother with those either. *disclaimer - replace or not replace bolts at your own risk.

Damping is the thing. Shocks regulate and control the movement of the spring. It's the spring that provides the support for the weight, as well as dictating the ride height (or so I'm led to believe )
 
correct, the springs do the heavy bit, shock absorbers do exactly what their name suggests... cars with bad rear shocks are easy to spot, once they drive over a ramp, for instance, the back end of the car doesn't stabilise as it should (pretty much immediately), but keeps going up/down for a significantly longer period as nothing to absorb the energy of the springs

Ok thanks I did wonder. Looking at the torque on the lower damper bolt and nut its 70nm which is fairly high for what I imagine is no bigger than an M10. The upper bolts only 50nm.
