have the Fuel injectors checked out.
loose exhaust
Normal for the 1.8t
can you elaborate? engine noise? stationary/moving? ticking, tapping or a definite knocking?
Unless you can replicate the engine noise with throttle manipualtion by varying engine speed to 1200 to 1800 rpm, you have a driveline noise
A tapping noise is generally the result of a bad hydraulic lifter, plugged oil passage to the lifter, or bad tappets. Sometimes just changing to lower viscosity high detergent oil will cure it. Or "Any automotive oil additive with the word MIRACLE in it".
Engine noise (tapping) than Rap and finally engine seizure
Possibly warped brake rotor/worn brake pads. Get this checked out.
because its new that's what happens or...the burning and tapping sound like low/no oil. I would definitely check the oil before driving it directly to the dealership. I checked the oil, its full. The burning smell was there when i drove out of the dealership but the noise only happened about 4 hours later.
If it is a Tapping sound it is normally a lifter. Could also be a cam, pushrod, and or a rocker arm. Tapping is normally upper motor. If it is a knocking noise it is normally in the lower motor. If the noise gets louder when warm most likely a lifter is going bad. As the oil heats it thins slightly causing more oil to bypass inside the lifter which it is not supposed to do
Check the Cats have not disintegrated.
the doors are being placed in locked position If it's coming from the engine or transmission area, I would suspect a cracked flywheel or flexplate.
that means you need more oil. it could also be a sticky lifter or slightly bent push rod or even the tappets out of adjustment
