Cool Replaced all 4 shock absorber! What a difference!!!

Replaced all 4 shock absorber! What a difference in handling and driving!!!

Long story short - Have had few problems for more than 1 year and tried many different things but problems were still there until now.

Problem 1 - Steering vibration over 65mph... sometimes the vibration was really bad! Tried many things such as 4 wheel alignment, new brake discs and pads, new Tyres, tyre balancing .. mechanic checked steering rack and all control arms and bushes, nothing was wrong! All mechanic inspected suspension and shocks and they all said shocks are fine!

Problem 2 - Violent Judder while braking at high speed! Tried new brake disks and pads, wheel balancing, new wheel hub and bearing ... nothing fixed the issue.

Problem 3 - Intermittent Clunking noise at low speed over pot holes or bumps, which sounded like coming from steering rack ...

All of the above problem is now solved just by fitting new shock absorbers .... car now drives and handles like new car even after 192K Miles ....

So... if you have any of the above problems and tried all usual things like new brake disks, wheel balancing, alignment... etc.. etc... and problem is still there I would suggest try replacing the shocks. I purchased bilstein shocks.

I get the same thing. Been suspecting a steering rack problem or even a worn tie rod end but this sheds new light!

Also added little bit power steering fluid too as suggested on this forum so that the fluid sit just slightly above the max mark! I had to add about 100ml fluid ...

Mostly motorway miles mate! Used to drive about 1000 miles every week ... nowadays a bit less ... I guess if those miles were city of local drive the car wouldn't stand a chance as it is now ...

ive started considering this too as a fix for my annoying niggles like noise when moving slowly over small potholes etc, also changed a wheel bearing last weekend hoping one of the noises would be down to that... it wasnt... also slight squeak from the NSR over bumps. Was thinking about looking at all the bushings too.

More so now given your review! It seems one of the shocks is a SACHS part too, which i dont think was an OEM part...

Very interesting news gang, I have 150k kms on mine and so far no knocks despite the awful road surfaces I encounter daily. I too suspected that my auto box had a serious problem until a mate suggested to top up the tranmission oil, the resulting change seemed like a new gearbox!!! Super smooth. Sachs was perhaps OEM???

2008 A5 coupe.
3.2 V6 FSI 2WD automatic S line.

Just had the wheels refurbished, the bodywork polished, rear badges removed and fitted the pedal box booster.

I dont know if Sachs is OEM, what makes me think that is that the NSF shock is the only one with a sachs sticker...
@gtx2010 what shocks did you get for yours ?

Sachs is OEM, if you have Audi part number on in, so look in the Sachs sticker you should see VAG part number like 8T0 ....
End of the day OEM Sachs, Sachs, Bilstein all are same and I believe made by the same people too ... just different prices! The cheapest I could find is the Bilstein ones and I don't think they are any worst then OEM if not better.

Maybe 3.0 TDI V6 suffers more than petrol models as the TDI engines are much more heavier!

Which gearbox do you have? and how did you top up? Thanks

I have exactly the same problems, last thing I think about are the shocks. I have had them ordered but I did cancel it. I have 146000km. So looks like I will order them again.

Another thing is to sell the car, but I didn't find any other car which I could like more than S5 V8 in price I can spend... (S7 could be my favorite for its V8 biturbo, but it's too big and too expensive).

New A5/S5 is design, quality and reliability crap like any other new car in these times.

Hmm I have issue number 1. 3 shocks were replaced under warranty 6 months ago. May add the final shocker to the long list of things to look at....thanks for the pointer.

Dear GTX, sorry I never saw your post please forgive. Mine is the 8 speed auto mated to the 3200 FSI petrol engine. My trusted indi does all of the work and I did not see how he topped it up but he told me that only about 100cc was missing, but the difference was amazing.

Add me to the list on this one!

Was quite concerned about it when I first bought the car, only to drive it home and find that it made those noises...

Strange thump/notchy type noise when turning steering past a certain point (just off centre, to the right for me if I remember).

Did some reading and apparently a new rack will sort it out

Think I'll live with it... It's only slightly annoying!
