I bought this car a few weeks ago and when i got back from vacation it was making this knocking noise when I start it, I checked the oil and it looked fine so I’m stumped.
It’s a 2018 Wolfsburg Edition

Hi, about two days ago my car started having issues turning over. The dashboard would light up, and two different ding sounds in different pitches would start playing. I couldn’t turn the lights immediately off so I would have to wait a moment for the car to calm down. I jump started it that night, and it worked. No issues the next morning. Tried starting it again the following night and same problem, only this time jump starting 2 times wouldn’t work. I left it alone for 40 minutes and tried again and it worked. Went to Autozone to get it tested and the battery changed. They told me everything was working fine, and said to get a battery corrosion cleaning kit to try and fix it. Later that night I used the kit and everything worked fine (other than getting some small sparks reattaching the negative terminal). I tried to start it again last night and it wouldn’t start. This video is what u saw it doing last night.

Is this a battery or starter issue, or something else?

I have a 2017 VW Jetta that has <80k mileage. It has the normal wear/tear on it, couple scratches, and a large dent at the top because a tree fell on it during a storm in 2023. The car is drivable, never been in a car accident, but it has a rebuilt title (because of the tree incident). Realistically, how much can I sell the car for? I know that I can’t get much from carmax/carvana/the dearlership because of the rebuilt title.

finished the exterior plastic make-up for her face, muffler delete with aftermarket resonator. Switched from 16 inch factory rims and put 18’s on with the ECS branded lowering springs. I will say the car rides way nicer when lowered, but these springs are noisey as hell, especially when cornering in an incline.

I love this thing so much, she just passed 100k too this summer. Hoping to get at least another 100k.

I should probably do my own oil changes as well but I didn’t want to do the work so I brought it in.

Edit: if I should fix myself what is the part number for the brakes I should buy?

Geez, I can’t find a straight answer. All I find is that crush washers should go flat side to the bolt, round or bevelled side to pan. This crush washer for 2013 GLI seems round on both sides. Only difference I can tell is that one side seems slotted (like in photo). If I had to choose which side is “flatter”, then I guess this slotted side might be it but seems round to me.

No way was i paying over $3,000 to repair cam shift position sensor/ tensioner. Instead purchased a used engine from LKQ and im back to like new!!!!

Went from my old 1999 Honda Civic to a 2026 Jetta, I’m loving it and it’s such a wild difference!

Hey y'all,
I'm in search of a good code reader for my ‘17 Jetta GLI as she just hit 111k miles. Are these 3 any good?

finally went fbo and custom tuned my jetta. it’s a blast so far only issues i’ve really had was my charge pipes to the intercooler blowing off (only happened once so far after getting everything on there right) was pushing it with a couple of buddies on the highway and the boost pressure was too high i guess. but only 2 1/2 months since ive installed everything, so i guess after a while it js slipped off. then blew a hole in my muffler cuz my pops and bangs were too strong(borla exhaust btw ☹️☹️) so it doesn’t sound too good anymore. other than that i haven’t had any actual issues that i know of
