Hi guys - is anybody else getting a tinny cheap metal noise coming from the brake pedal when you lift off your foot ? The brake pedal is made fom a very thin alloy which comes across as cheap as chips. It does the job but has a tinny sound when I lift my foot off to press the accelerator. It sounds as if it needs a rubber cushion of some sort at the other end of the pedal up underneath the lower dash to dampen the movement noise. If you can imagine a cheap lightweight see saw with the pedal at one end and the piston at the other. The pedal jumps off the see saw and the other end clanks to the ground. Sorry for the comical description guys but it really sounds cheap and its the only way I can describe the noise. Ping an empty beer can with your finger and your nearly there. New q5 s- line

Yes my new Q5 makes what i would describe as a 'clang' when i release the brake pedal. It is intermittent but pinging an empty beer can is a fair description. When it is doing is makes no difference whether you're stationary or not.
Vehicle is booked into the dealer to have this noise investigated next week, let's hope that it happens for them.

Hello all, yes I have exactly the same thing, not in a bad way but thank god you all have the same thing ( I was thinking what else have Audi messed up on the new Q5)

Annoyingly I can't recreate the noise, it seems to happen on and off. Over time I can only imagine this getting worse?!

Trouble free motoring I don't think so... the fact that I need to go to the dealer again is such a pain!!

Please keep us updated on what the dealer says and I will do likewise, it feels like we are QC the Q5 for them as Audi clearly haven't done.

Saying that it has only happened around after 500 miles of driving.

Hi guys - it only becomes really obvious when I may be sitting at a busy junction or roundabout and have to take my foot off quickly to hit the accelerator. I really think that the pedal has been manufactured from light alloy and this is a consequence. I feel it should have some sort of rubber damping to stop the 'clang'. It doesn't make that noise when I am cruising around in normal driving. It just makes this 'clang' when I release the brake quickly. Surely this should have been picked up in the development stage.
STOP PRESS
Sorry to keep 'clanging' on about this but I managed to get my camera up behind the brake pedal to have a look around. There is a gap in the trim which allowed my camera to look through. If you can imagine your head behind the brake pedal looking back towards the drivers seat. ( you can tell it's eating away at me lol) there is a circular shaft which the brake pedal is welded too- this shaft rotates when you hit the brakes. It's at the end of the shaft above the footrest area that seems to be the area of concern. There seems to be a lot of thin metal/alloy brackets that could be the cause of this clanking noise when the pedal quickly returns to its normal position. If you kneel down on the ground and have your head in the area of the brake pedal- give the pedal a sharp press and off again with your hand. You can only do this about twice because the brake pedal pressure starts to stiffen the pedal up. My neighbor came over to make sure I was ok as he had seen me on my knees at the side of the car lol.
So to be honest I don't think there is anything actually wrong with the brakes, but it seems to a consequence of using lightweight metal brackets and fittings in the brake pedal assembly. Any brake pedal on any car will make a noise if you bring your foot off fast, but it would appear they have missed out the fitting of a damping washer/pad to compensate for the use of using lighter materials. I must get out more lol.

Ok thanks for update. Let me know if they decide to try and fix it. Not sure if they even know what they've sent out to customers...

It is unfortunate but seems the first year of any new major change and we the users are the beta testers. I saw it with my own car (not Q5) which ended up being rejected for a replacement. Kind of vowed then never to buy a fresh out the box model yet here I am about to get a Q5 ordered for family member...just hope 6 months or so if build time and user feedback alongside double QC will have major impact on improvement for the Q5.

Plus the MLB platform has been around a couple of years now most major issues should be ironed out ????????

Haven't noticed it on mine which is 2 weeks old and about 700 miles in. I'll listen out for it. On the point about being Guinea pigs for new models, there will always be little niggles but keep it in perspective as hopefully you'll have thousands of miles of trouble free motoring.

Further to my investigation into that clanking sound from the brake pedal. Check out the burned metal in the enclosed photo. Zoom in to the central area and you should see a section of metal which looks as if it has had an oxy acetelene burner on it. It takes quite a bit of heat to turn metal this colour. Somethings been going on in this area and looks like some modification has taken place using a burner. No way should a section of metal be like this in a new car. It's been heated for some reason to either bend it or cut something off it. Stuck at Emden for weeks getting 'quality checks' my ass. Just noticed that the photo is on its side and should be vertical

Not that I would know but that doesn't look normal to me. Looks like Audi are covering something up or failed to pick something up in QC.

Poor that they've let them go out in this state.

My new Q5 goes back into the dealer tomorrow to investigate this brake pedal 'clang', I'll post their findings when I get the car back.

I've also now noticed that there's a noise coming from the brake pedal of mine when I lift my foot off quickly. Geoff3 let us know how you get on at the dealers as I might be doing the same.

I am still waiting on my dealer phoning as he said he would do to organise a date to take my car in for investigation. It's an awkward one to demonstrate to the dealer what the problem is because if you release the pedal quickly while stopped with the engine off, you only get a couple of chances before the pedal pressure tightens up. If you start the engine again and release the handbrake, then activate the handbrake again, you get another couple of goes to demonstrate to your dealer/mechanic. Just take the dealer /mechanic out on a short drive to let them hear it. I've had a further look at mines and it would appear as everything is so new and tight, when the pedal returns to its normal position with some force. The area with the black bracket with drilled holes in the side which can be seen in the picture I posted on the 14th may which includes the white plastic 'sleeve' - seems to be resonating with the force of the brake pedal returning causing this 'clanging' sound. I also think the metal which has a burned appearance in the photo I posted is resonating as well. Is this a result of this metal being 'modified' and being no longer attached to the brake pedal mountings which would explain the tinny noise ? I think this burned area needs to be stabilised to stop it ringing with the force of the returning pedal.
I know this platform is used by other models and you can see unused mountings in my photos. Is this burned area a result of modifications to suit the Q5 ? Burned metal in every Q5 ? If it is then this area needs to be solidified to stop any metal parts 'ringing'. If you hold the metal of a bell whilst striking it, it won't ring. Release the grip and it will ring or resonate. This is what seems to be happening above the brake pedal. Aaaahhhhh - feel better that I got all that off my chest lol. Six weeks in quality control lol - pull the other one. Best of luck guys in getting this resolved. Not just for us, but future customers.

Any further news on this at all? I wonder if this is one of the (potentially many) reasons and all links in to what rifleman was told about production suspension....

Hi Nemo - my car is booked in near the end of the month. I do a lot of town/city driving so quick exits at junctions etc happen a lot. This is where I am getting most of the clanking sound when I release the brake quickly. The brakes are ok- it seems to be the metal that the brake pedal housing is made of or attatched to that is resonating. Ping an empty beer can and it's almost the same sound I am hearing. Metalwork around the top of the pedal area needs stabilised. I am still concerned about that burned metal area which can be seen in one of the photos I posted. It could be that section of metal hanging there after being burned off that is causing the noise. So annoying considering the car was in Emden receiving 'extra quality checks'.

Thanks - hopefully they'll answer why it's like that and whether there is any issues with it...fingers crossed not and guess what whenever the car arrives 2017/18 it'll be one of the things I'll check on handover ????????

My new Q5 has been in the workshop for two days and they want to keep it to continue their investigations next week. That have agreed there there is an intermittent abnormal clang when releasing the brake pedal but as yet have been unable to trace the cause. I'll keep the forum updated with any news.
