Hi has anyone here with a 2007 Q7 3.6L having any noise problem with there car when you first start it sound like a diesel for about one to two minutes.

 

Not sure if you ever got a response here...but my 2007 is just plain loud all the time. Disappointing for a "luxury/performance" car. I do get a quick deisel like "banging" sound for only a second when starting cold. I'm told it is just how it runs...again, disappointing for an expensive Euro.

 

Engine noise is due to the excessive clearance between two metals i.e. from a broken valve spring to a valve lifter sticking....so just hear and identify where the noise is coming from.....

 

I have a 88 chevy silverado with 350 engine, recently I noticed a squealing noise under my hood and it is mostly noticeable when I start up the truck or when its idling. I think its my belt but I am not sure? What could be the problem, and how do I fix it? Thanks.

 

Audi Q7 is a luxury full-size crossover SUV launched in September 2005 Frankfurt Motor Show. Q7 Production began in autumn 2005 in Bratislava, Slovakia. It is first Audi SUV offers. The Engine Noise has smooth and comfortable.

 

i, too, was wondering if it was just my car in particular that has a diesel sound when starting the car COLD. after some research across many forums, it sounds like it's normal to have that sound for the first 45 seconds after starting the car COLD. however, as the RPM drops below 1K to about 800 RPM, the engine sounds more normal, right?

and it happens mostly on COLD starts, and not every start. (i.e., if you just turned off the engine within 30 mins and turn it back on, you don't hear it right?

 

Sound coming from the engine. Reviewing briefly the cockpit to reduce engine noise, Dynamat and individual parts or bad parts of the engine noise through the radio.

I am going to buy a 2012 Audi and I am not sure whether the water leak issue and the break issue is still persisting in the new 2012 model's as well.Your kindly reply will be highly appreciated.
