2005. 5 vw Jetta, 2. 5l 5 cyl engine. Car has been maintained according to manufacturer guidelines. Vehicle was operating normally when check engine light came on. Check engine light was lit steady, not flashing. Started to lose power and was difficult to maintain speed. Pulled off road and idle was very rough. Turned car off and back on and idle was worse and check engine light still lit and not flashing. Vehicle started to make grinding noise from driver's side of the engine compartment. Was difficult to move vehicle under its own power and had car towed to repair shop. Repair shop found trouble code p1340 and after more diagnostic that timing was incorrect. Cam timing was very far off and stretched timing chain suspected. Compression test revealed bent valves as well. Local indy mechanic and local vw dealer have both seen this issue several times with 2005. 5 and 2006 model Jetta and rabbit vehicles with the 2. 5l engine, and several other similar failures are outlined in several places online. The failure of the timing chain was very sudden and could have caused an accident.
Any time the vehicle is not operated for a few hours or longer, the engine makes a very loud grinding noise upon starting. The noise lasts less than 30 seconds, then a high-pitched noise follows before both noises cease. I have been experiencing these noises since I purchased the vehicle. I took this vehicle to the dealership for repairs due to this noise, and was informed that there was nothing they could do and that all new vehicles on the lot were making the same noise. The salesman suggested that the grinding noise was the catalytic converters starting up and the high-pitched noise that followed was the fuel pump. Still, it does not sound normal, and the noise does not occur if the vehicle has only been resting for a matter of minutes. I find it difficult to believe that a normal function of the vehicle would make such a noise, and then only make it on certain occasions.
When the car has been sitting for a couple of hours it makes a loud grinding noise when you start it. This lasts for about 20 seconds and then goes away, but it occurs everytime you start the car after it has been sitting for a little while. I was told the noise was normal by my sales rep. I have had the car 2 and 1/2 months and the noise just doesn't sound right.

I was told it was the secondary air pump and that it's normal. We've had the car for a week, and the noise just doesn't seem right.
