Hi guys - I'm no mechanic but apparently there is a link made up of a rod between the servo and the master brake cylinder, which loosens or tightens according to the pressure maintained in the master brake cylinder. Before I had my servo replaced, then the cylinder, if I sat and pumped the pedal till it was solid before I started the car, I would not get any clang till the pressure dropped whilst driving when the pedal would lose its firmness and go spongy. The brakes worked ok, but during the first 10 minutes of driving the brakes were solid and very responsive. So is the problem due to pressure loss and/or the ability to maintain a certain pressure in the braking system within the servo and cylinder areas. I know this car shares a lot with the A4 etc, but is the servo and cylinder assembly unique to the Q5 ? Why are some cars ok and others have a problem. What is changing after a certain milage that causes the clang to be heard but wasn't there when the car was new ? My pedal is still quiet after the work to replace the servo and cylinder, but is still not 100% fixed.
It's a real shame that this is spoiling ownership for many people, and should really have been picked up in the development and testing stages of the new model. But when QA did their checks and couldn't see a kickplate light was not illuminating or windscreen washers spraying down onto the body rather than the glass etc etc. It makes you wonder if Audi have lost their grip on what is actually going on during the production and assembly stages within their new factory in Mexico. There were concerns about the quality of assembly which the factory may produce before it even opened. But if the workforce are assembling cars consisting of parts and trim etc which in some areas are not of the highest quality. Then the buck bounces straight back to the research, design and development departments of Audi which were responsible for producing and picking parts and materials etc for this car.
Right- feel better now that's off my chest. I like my car but feel Audi have penny pinched a little too much and missed a chance to produce a car which should have kicked all others into touch. It's good- but I still think the Mk1 was a more robust car.
Love my Q5 but agree about the penny pinching and my mk1 was definitely better built. The way the insulation has been left in the boot for example is a joke and the brake clanging is so disappointing especially with no fix in the pipe line.

Hi guys - as far as I know the Mk1 was built in Germany that supplied the UK. There would have been some issues with customers cars as happens with a lot of new cars. Even though they go through the same build process. The design and materials used in the Mk! may have resulted in a slightly heavier car, but it felt more solid and better put together I think. Cheers
 
My first post so please bear with me, I have read this forum for many months now for opinions on the car, and have just purchased a new Q5 TSI S Line. (No more diesels for me.....), purchased from Bristol Audi showroom new stock with a good discount of approx 10%.

The brake pedal is perfect, no noises at all and a damped return, just as good as the 18 month old Golf R that I traded in (great trade in price as well).

I am also surprised how much torque the car has, it seems at least as good as my mates TDI, but the TSI is so relaxingly quiet that I forgive the less mpg economy for the relaxing quiet ride.

Just waiting for the new car rattles and clonks to start .........................

Welcome and enjoy your new car.
I've been driving a loan TDI S line for the last 5 weeks and am looking forward to picking up my TFSI S Line next Saturday and seeing the differences. This will be our fourth new petrol Audi.

Hi Hellisup welcome to the forum and glad you are enjoying your car. I also have the TFSI S-Line and happy with the mpg. Dynamic mode really shows what the engine can do when you hit the pedal. Hope your car stays rattle free. On a regular round trip of around 16 miles in light traffic, I get 34-36 mpg average. Another trip I do with lots of coasting down hills has shown 44mpg. I just love the coast mode and take my foot off the pedal going down any hill I come to. As there is no braking from the gearbox, the car just keeps going and going. Yep- nice car to drive despite the issues I had at the start. Enjoy your car. Cheers.
 
This will be my second Audi, my first one was a new 2013 RS6, a fault free car, but as am now 60 years old I do enjoy softer suspension and a quiet car.

Used to be a BMW customer but the build quality of BMW is now the worst ever, from paint, interior, mechanical to electrical problems, my last new BMW 535D just lived in the dealers unable to be fixed (yes never fixed) so sold it 8 months old, so no more BMWs for me.

Our family has changed to VW / Audi cars now and all have been completely fault free since new (one with 60,000 miles), just ordered an A1 TSI for my wife.

Justanhonestman..........

The coasting is a new experience for me, I feel out of control when in coasting mode.

does coasting mode only work in Economy setting? I know what you mean, but just touch the brake slightly and the gears do re-engage

Hi Helisupp/Mjr2004 -- I know what you mean about feeling out of control when coasting. But I only use it when the road ahead is clear of traffic and my foot hovers over the brake pedal ready to brake and bring the revs back up. Once I clear a bend etc after braking and get to open road again, I give the accelerator a press to bring up the revs then release my foot to coast again. I'm able to do this a lot in my area as it is quite hilly. To be honest I can't say if coast mode only works in eco mode. I do most of my driving in eco mode and when I go to dynamic mode, I enjoy it so much I don't want to take my foot off the pedal lol. I will try different modes later today. The coast mode also works on the flat too. If I am approaching a roundabout or junction which is a few hundred yards away, I take my foot off the pedal and the car just coasts up to the junction at tickover revs till I hit the brakes. I've noticed too that the green foot lift off icon on the dash shows as I approach most larger roundabouts in my area. Is this icon getting signals from the sat nav ? The icon shows more or less at the same point in the road when I am out and about approaching various roundabouts. Something else to keep us amused when the music on the radio is crap lol. Cheers.

I wouldn't be surprised if all the new Q5s have this problem and the only reason some display the issue immediately, after 100 miles (500 miles in my case) or not at all is just down to tolerances within the materials used.
Changing major components in the braking may in some cases cure or reduce the effect or make no difference what so ever.
After waiting 7 months, 2 news brake servos and weeks in the workshop and waiting for Audi to take this seriously I have very little faith that they will ever come up with a cure.
I find it hard to take Audi's claim to be a serious contender in the 'quality car' market while they show such little concern for their customers some of whom have spent well over ÂŁ40K for these 'clangers'.

Sadly I have to agree with you that I don't think Audi will come up with a fix. My wife has a mk3 TT Roadster which suffers from a common fault with other TT's. The seal inside the door panel freezes when it is cold and the glass in the door won't drop to allow entry, if it does you cannot close the door meaning you cannot drive the car, lock the door etc. Audi have been aware of this problem and still cannot remedy the fault there is approx 160 posts on the TT forum but still not resolved.

Being able to drive this car between Nov and March is a lottery depending on the weather. We love Audis and have been privileged to own many over the years but really getting frustrated now. Incidentally had this problem over the weekend again but this time the regulator went, car door wouldn't close so the car had to be taken to Audi by the AA on the back of a low loader so don't know when we will get it back!

Congrats on getting 10% discount, I also purchased a stock Q5 in March and got approx 8% discount, crucially for me I also got a fair price for my p/e so the overall price to change was better than anticipated for a newly launched model.

How does the green foot lift off icon work, when it comes on in the car, does it mean lift off, it seems to stay on even if I do lift off. Is it telling me what to do, or what I have done..........

My A4 cabby has the same problem, I run a bank card along between the glass and seal and give it a skoosh of deicer then lift the handle and make sure the window has dropped before actually opening the door. Seems to work, still a PITA though.

Hi guys for many years I had to leave for work around 5am or finished work at 6am as my job consisted of shift patterns. We can get some rough winters up north and the car resembled a mini iceberg at times during the winter months. If it snowed then thawed then an early morning frost froze all that water laying in the seals, then ripping the seals from the door opening as you opened the door was a big possibility. I smeared vaseline on the door seals over the winter and my door usually opened no problem . I just pulled the door open slowly keeping a tension as I pulled the handle away from the car. The glass is easily cleaned once the weather gets milder and it keeps the rubber seal supple. Worth a try slipping some vaseline up into the groove - ahem.

Hi Helisup — as Nemo says it is telling you or advising you to lift your foot off the pedal to save feul as the cars momentum will keep the car going till you reach that roundabout or maintain its speed as you go downhill etc. The green icon will stay on until you stop coasting and use the pedals again. You don’t have to do this every time the icon shows, but with no engine braking as manual cars have, its amazing how far the car can travel at tickover revs down even the slightest slopes before you have to press the accelerator again.

Hi Geoff3 I really wish I could answer your question about why some cars are ok and some get the issue after racking up some milage. My car had the issue on delivery. Most parts and fixtures on a new car will eventually ease off after use and wont be as tight as when new. Were the tolerances for the brake pedal area set too high when the car was first produced, resulting in the clang from new ? Have the tolerances been tightened up resulting in the system taking longer to produce the clang as the parts ease off after driving the car for a while ? Somebody who does a lot of town driving from new will use the brake pedal more often than another owner who does a lot of motorway driving sitting at the same speed for a while. Is this the reason some clangs are heard after 150 miles of driving, where others get 1500 miles before the clang is heard ?
Is it the result of pressure loss from new as the parts bed in? I am still sticking with my original theory that there is a lack of cushioning fitted to the moving parts connecting the servo to the cylinder and brake pedal assembly which is producing this clang. I think we will have a long wait on a resolution.

Congrats on getting your new Q5. I note you say your getting a relaxing quiet ride, would you say that road noise is also quiet and can I ask what tyres are on your car? My TFSI is 3 weeks old and I'm thinking of changing the Michelin's on the car as they appear to be very noisy. My dealer is looking to try non-Michelin Tyres. Oh, and my brake pedal started making the clanking nose from about 200 miles.
