Hi folks, how's things? I have a very loud Scraping / Grinding sound on front of my engine. The noise is external, as apposed to inside the block. It could be coming from either the timing area, the serpent belt adjuster, one of the pumps or the Alternator, I can't work out which. The first 3 days it made the noise I crapped myself, thinking the engine was about to explode, or something was going to fall off. By the time I opened the bonnet the noise had gone. The noise was/is like twisting a shuvel inside a metal bucket, but at a constant faster speed, maybe twice a second at tickover/idle, and scraping more on one side of the bucket than the other. After the choke closed the noise went away within a few seconds and the car drove without issue. On the 4th and 5th days the noise didn't go away, but again became quieter (more quiet) as the choke closed & the revs dropped, which I would think to be logical; it is still quite loud, as opposed to very loud. The noise does increase with revs, as I assume would be expected. The engine starts & runs ok, but does appear to run a little laboured, but only a little... I have my suspicions, but thought I'd throw it out there to see if anyone agrees. Any suggestions or advice would be appreciated and gratefully received. Thanks, Paul.

Hi, I purchased a new Q8 in November 2019. Ever since I’ve owned the car, the brakes appear to ‘grind’ at low speed, especially when cold. They also squeal at times. I’ve had multiple cars of this value from other manufacturers and never had this problem before (in fact, we also brought a new Q5 for my wife at the same time, and she has no issues with this). I’ve been back to the dealer and they claim it’s ‘normal’. Is this correct ? I just wanted to check other peoples experience before I go back again. Thanks

Good Morning All, I'm sure this topic has been done to death, and thus far google has shown this is a common problem.... So, to start from the beginning of my woes. During a 3 point turn, I lost all power steering as the hydraulic fitting on the end of the pressure pipe from the power steering pump, where it joins to the rack (Back of the engine bay) had corrodded so badly, it failed, dumping all my power steering fluid. I have replaced the hydraulic pressure pipe from the pump, with a like for like, made by a local hydraulic specialist. Since then, I have had the pleasure of the grinding juddering steering. We have been through the wheels in the air lock to lock bleeding process countless times, and air continues to come out. but the problem does not go away. We have ruled out turret bearings, as in the morning, when the vehicle is cold, there is no problem, it is only when the vehicle becomes hot that the problem occurs (plus it didnt do it before the pipe burst, so i can imagine that the burst pipe would cause the turret bearings to fail). I did drive the vehicle about 500 yards with no power steering, (had no choice, couldn't abandon it where it was) We have replaced the pump. So, the symptoms.... The low pressure return pipe from the rack judders like a good one when its happening, and juddering can be felt through the steering wheel, and steering rack. The symptoms are consistent with air in the system. It seems that this is a difficult problem to solve, and has lead to people replacing racks, pumps, pipes and eventually cars. Someone must know the cause? I'm interested to know if anyone has a trick or a method of fully bleeding the rack to get all the air out, as when the wheels are off the ground, going lock to lock, listening to the rack, it does make some interesting noises, much like there is still air trapped in it. I would appreciate your thoughts and experience, as i am determined to beat this somehow! Regards Darren

Hi all, I have an Audi A3, 2015, S-Line, 2.0 TDI, Diesel and I have recently heard a faint grinding or crunching noise coming from the engine area, like a 'Skrrr Skrrr' noise when the engine is stationary. I have taken it to Audi several times and they are unable to rectify the fault. I am concerned that it could lead to something major and cost me a pretty penny in the future. I have attached a video for the sound to be heard hopefully over the loud diesel engine. If anyone would be kind enough to identify the noise or fault, it would be highly appreciated. IMG_2649.MP4

Hello, I purchased last year a black Audi A4 3.0, V6 Quattro Cabriolet. Great car so far, one thing is really bothering me however! The clutch when pressed has a rough 'grinding' feel to it. I think its got worse over the past few months. The clutch seems to work fine, with no slippage etc and there are no noises that associate with the rough feel, but its now really ruining the drivability of the car. In addition, when the clutch is pressed and when I rev the engine, I can actively feel the revs through the clutch etc. Could this be the clutch release bearing? If so, big job or total clutch replacement. the car has the original unit and is on about 80k so far. Or could this be the DMF. I'm not quite sure what the usual symptoms of that would be however? Any advice is appreciated!
