I have had my Q5 3L diesel for over 10 years now, and it is approaching 200,000 miles (320,000 km currently). I just had a gearbox failure which thankfully was just a broken fluid pipe and a replacement/ fluid change fixed the problem. I also have spluttering at idle, and when I just start moving, I am thinking this could be the fuel injectors. I have never used the additive. It is worth trying it, does it work? I have been looking at a replacement Q5, but all the diesel and even the most of the petrols seems to be slower than my current car - my car has 240BHP/ 500 torque and does 0-60 in 6.4s. Only the top of the range Q5 50 TDI manages this now!

Magnet, thanks for the advice, I'll take it is for a full assessment. Steve Q, No I'm a doctor, I do lots of miles driving on call and in-between hospitals, hence why I've racked up 125k miles in 7 years, most of which is motorways and dual carriageways, and I've never towed anything. Thanks again.

Thanks for the reply. It has been to both, Audi first, then an independent garage when Audi didn’t solve it. I could try a different Audi I suppose.

Hi, I have a 2011 Q5 3L diesel. It has now done 145k miles. I am the second owner and have owned it since 30k miles, over 7 years. The car has been faultless (except one problem with the air intake that was solved), but over the past 10k miles it has developed and odd rattle on breaking which the garage has not been able to diagnose. This rattle makes the steering wheel shudder and I can feel it through my foot on the brake pedal. It occurs on breaking but only at a very specific breaking point: if I break with slowly increasing intensity, it will shudder only at a certain compression of the breaks, not before and not after. This range is very small. It is worse at higher speeds and when it is warm. When it is cold (under 10oC/50oF) or I am slow it is barely perceptable. Even more strange is that each time the dealer replaces a part it solves it for a few weeks and then it comes back. So far this includes: One set of front suspension arms. ....the rattle went and then came back. A different set of suspension arms. ...the rattle went then came back. The front brake disks and pads. ...the rattle stayed off for two months and has now come back worse. (There was another part replaced first that I cannot remember.) The mechanics have no idea what to try next, and this trial and error is very costly. Any ideas? Thanks Gordon
