The car tends to bounce when going over bumpy road surfaces.
a suspension workshop said that the rear suspension needs to be changed - at considerable cost.
Question. Is there any way that the system can be be serviced or repaired.

When someone reports a knocking from suspension a garage is unlikely to spend much time unless the knocking is either obvious or can be duplicated by bouncing or rocking or it is a very favoured customer.
Typically suspension/steering knocks and rattles do not cooperate and disappear once in the garage and so they must check the vehicle is safe and leave the rattle or knocking to develop. Lots of things can cause noise without being dangerous.
I was a mechanic in a garage in the days before time cost so much money and we took a different view of things. Then if someone brought us a rattle we mostly found it and cured it but sometimes the entire staff was employed driving around, bouncing, shaking , listening and sometimes it took hours. In those days the customer never paid for diagnosis - only the repair. That could not happen today...
On the right sort of road surface at the right sort of speed apparently good ball joints, steering racks and suchlike can produce awful noises. These sort of things often need to be checked and rechecked over a period before the source becomes obvious because road conditions cannot be duplicated in a workshop on a stationary car and no checking can be done on a moving car. It can take patience...
One typical knocking that is very difficult to locate is noisy valves inside the shock absorbers. Historically some car brands suffered a lot and others were no trouble at all so it is unsurprising some mechanics have never even heard the sort of racket they can produce that is obvious to no one except the occupants of the car.
The thermostat is located in front of the engine, between V cylinder banks, for Audi A8 V8 4.2 Quattro Automatic. See pictures below:
Remove the thermostat housing (2 bolts) and the old thermostat. Note the orientation of the old thermostat (vent valve facing UP). Clean both thermostat housing and block surfaces and remove all traces of old gasket material. Install the new thermostat vent valve facing UP.

Could one shock be bad? Causing a difference in bounce return rate? I would crawl under suspended car and check all suspension bolts. Are your bushings in good shape? If one is chewed up or missing then this would cause that misalignement. What kind of suspension do you have? Solid axle or independent susp? I don't know if your car is front or rear wheel drive. I'm guessing front wheel drive.
Temp sensor is at the right hand rear of the engine (left side when looking from the front). You can get to it from above without too much issue.
They regularly fail and are a cheap replacement part. They don't throw diagnostic codes. Go genuine, or Bosch.
To replace, you pull the retaining clip out to the rear (be careful, they get dropped easily). The sensor itself pulls out, but will probably be stuck in slightly, so don't damage the cars plug pulling it out (disconnect plug first).
Make sure the o-ring comes out too, or go fishing for it (they can be brittle and break with age). New sensor will come with a new o-ring.
