Greetings all,
I know noise diagnoses can be a joke amongst car people, so I'll do my best to paint a proper picture.
2012 Jetta Sportwagen - DSG - 112k miles - stock—Since the sound comes on right around 2,000 rpm as the turbo starts to spool, and drops off on upshift, I can only assume it's the turbo:
it's a quiet, yet distinct metallic, almost grinding, or tinkling sound—as it's coming through the firewall, it's a bit dampened. It's definitely metal on metal. The more gently I accelerate, the longer the duration, but it's only 1 second or less. Giving it the beans it lasts a fraction of a second. So like right as the turbine spools up. I haven't tested it in manual mode to see if it holds, but I'll give it a go tonight.
I recently had some warranty work performed (new exhaust filter among other things), and before this, aside from the turbo lag being more pronounced because of the exhaust lack of pressure, all I could really hear was the pleasant pressure/wastegate-like noise. When I got a persistent MIL and computer malfunction light (MIL would come on and turn itself off before), I took it to the dealership to perform the warranty-covered work. ON the way to drop it off, the turbo made a weird noise, possibly from the clogged soot filter they replaced
list of what they did here:
Aside from finding and fixing a bad connection on injector 4, nothing else came up in their multi-point inspection. I know dealerships have bad reputations, but I'm glad they were at least that concerned to look.
Is this noise something I should be concerned about? Should I take it back to them? ignorance talking: I was told that everything save the block was covered in the emissions/dieselgate warranty, including the turbo, but please, PLEASE correct me there. Also, I discovered they can't do anything until there's an MIL on, which prolonged my JSW's stay at the dealership (it would turn itself on and off)
Normally I wouldn't be such a worrywart about a strange sound on a used vehicle with over 100k miles, but if the grinding is sending metal shards into the cylinders, I don't want to wait that one out…
Thanks for the advice, and let me know if more detail is needed.
