2018 VW Tiguan SE

I’m pretty sure after replacing my turbo gasket that failed from exhaust nuts backing out apparently, my Wastegate or charge pressure actuator has failed. With ignition on engine off it’s free to move, after activating it in vcds it’s firm but I can move it and it does not adjust position. When running test in vcds I do not hear or see any movement from the actual rod. Any help is appreciated. I do have 230k miles on this 2018

What is the actuator part number that WILL fit?

Need help with what all I will need for a home repair

I have a 1997 Honda civic DX, 1.6 L 4 cylinder.

The issue it’s been having is after driving it some (anything over 10 minutes) the hose connecting the radiator and the coolant reservoir pops off

I assume it’s a head gasket issue, even though the oil isn’t milky it does look like oil builds up in the coolant reservoir. And I assume the hose pops off because of engine pressure getting into the coolant system.

All that being said. What do I need to replace a head gasket? I know I need a whole slew of gaskets and bolts that are all one time use. But what are all the gaskets and bolts called? And what tools am I going to need to invest in? Does anyone know a good head gasket changing video for a 1996-98 civic?

2013 accord sport alternator question.

Like many cars this one cuts alternator voltage for better fuel economy during low load events.

The problem I'm having is the voltage is dropping when I accelerate. Watching live data it goes from 14ish to 12 ish at half throttle or more. Let off and 14v's returns. It's noticeable with the headlights on and you can hear the hvac fan slow down.

There is a single wire on the side which I assume is either commanding the nator or sending data. Unplugged I get 14ish v's all the time.

My question is WTF. Well what is the process it uses to drop voltage. Is there a module somewhere that could be replaced? A little research points to this black box right off the negative terminal but I can't find anyone else with the same issue.

Car making clunking noise when braking, don't know where to start looking

Here's a video, could not upload to Reddit, sorry

2011 Hyundai Sonata NF LPI

G4KA 2.0L Engine, 558k kilometers

This clunking noise has come on few days prior, and I cannot find the cause. Any help would be appreciated, can send more images or videos if needed.

Visited the mechanics few times, changed the CV axle prior to this on front right side, and upper control arm, made no difference. Visited the mechanics few times.

Broken Clutch?

Hi everyone.

I have a 2007 DRZ 400 sm for about a year now, and it gave me lots of problems.

Seems i still have to understand what's wrong with the electric implant, but that's another story.

I start by saying this is my first bike and i dont know much about mechanics.

One morning i go to the garage and i try to start the bike but didn't start (dead battery or alternator) i was late for work so i start panic and i start try to jumpstart. I was panicking so instead of dumping the clutch in 2nd , i do it in 1st. Nothing, i then give up for the day. Put the battery on charge and i decide to try another day. I know that probably i did some damage while trying to jumpstart in 1st, im an idiot, i know.

With full battery, the bike start but cant move. (When i release the clutch is like the chain is being stucked on something. The chain was actually kinda old and for sure i would have had to replace it. I tried putting on a stand to let the rear wheel spin and try to see what's happened. I don't really know what could be (except maybe pinion or sprocket) and how to explain it. While letting the wheel spin i could clearly see it wasnt spinning smoothly ( in gear obv ). Could it be that something snapped while tryng to jumpstart the thing?

I don't know if its worth fixing it or just selling it for spare parts or if i should just rebuild the engine. Again i know im stupid af, but i would like to see if i can save the bike.

Sorry for the long message guys.

Thx 2 everyone who reads/respond to this

Thanks to everyone.

Audi S3 8V 2017 - “Strange”noise coming from Engine Bay

Hello All,

I have had my Audi S3 8v 2017 for about 6 months now. I have only recently noticed it, but when the engine is running there seems to be a loud “ticking/rattling” noise coming from the engine bay.

I see a lot of things online about these cars having high pressure fuel pump’s which can cause this, but was unsure? Last serviced in Feb and nothing noted because of it.

Thanks all- any help or guidance would be greatly appreciated.

I have attached a video for reference (this is when car was warm, but also makes same sound when cold).

Dodge ram 1500 2001 ABS issue

Could this be my problem with the ABS? It generally could've caused an actual wreck because it would not turn back on and was in the middle of the road while it was raining and we cannot do anything about the windshield wipers

I don't know much about vehicle vehicles

I'm just a son worried about his mom driving

This is by the back axle I think again I’m not a mechanic I’m an idiot

Where is this piece from?

Found this broken part underneath my car after it was slammed when I was releasing my car jack. I have no clue where it's from or what it is even after I checked around my engine bay. Where would this broken piece be from?

Car is a 1997 Toyota Corolla 160iGLE, with 4afe engine

Tucson 2025 noise

Hey everyone,

Lately in my area the fuel quality has been really bad ,very low octane. I started noticing a strange sound coming from my engine as in the three clips in the video.

The sound mostly happens when I press the gas, and sometimes it becomes very fast/rapid. As soon as I lift my foot off the accelerator, the sound disappears.

Is this typical engine knocking, or could it be something else?

If I keep driving like this, will it get worse or cause serious damage?

Also, if I switch to higher octane fuel, will the issue go away, or could there already be damage done?

Battery keeps dying on my 2017 Ford F-150, what should I check first?

My Ford has been having battery issues lately. Sometimes it starts fine, other times it barely cranks. I’m not sure if it’s the battery, alternator, or something draining power overnight.

Sell or Fix an oldie but goodie?

Hey everyone,

I have a 2008 Mitsubishi Lancer GTS with 138,000 miles (original CVT transmission). I've only done routine oil changes, no transmission fluid changes because it wasn't mentioned in the owner's manual. The car needs new control arms and outer tie rods. I got a quote of around $2,000 for the full job including alignment.

I'm currently in California and will be moving to Florida (will ship the car) for work in the near future (driving ~5,000 miles per year once I'm settled). Importantly, I'm not noticing any transmission issues at all right now — shifts are smooth and normal.

AI is suggesting I sell it because the transmission might fail soon, and to use the money toward a newer car.

Quick questions for those familiar with these cars:

  • If I get the control arms and tie rods done now, do a proper transmission fluid change, and then maintain it routinely going forward, what's the realistic chance this car lasts me another 3 years?
  • Is it worth sinking money into the suspension + trans service before a cross-country move, or should I just sell/trade it as-is and buy something more reliable in FL?

thanks!
