Hi! I got this automatic headlamp switch with 2 sensors. I need auto function to always turn on headlights, no matter how dark/bright it is outside. Tried to cover both sensors with a black tape, but for some reason lights didn't come on until i covered switch with a hand at least for 1 second, and then relay turns on lights and they stay lit.

Maybe someone have this switch and can give more insight? Thank you! :)

Hello, which one of those two options ist the right way to lift the car? I want to remove the tire because it makes a weird noise. The now grey parts (under the doors) have been swapped due to rust and now there is not this gap, that you need to lift the car. Is it safe to do it like I do now?

Apologies for the noob question, I was on a long drive yesterday using the fan, No ac as its broken so just the fan. And ocassionaly a semi strong smell of petrol would enter the car, it would come and go but no smell when fan was off.

Car has been off and parked overnight smelt a petrol smell in this area and located a slightly split hose on either side, of what I think is the EVAP system? Would this be the reason why? Can anyone advise? It's the hose that attaches onto the nipple.

Hello all fixing this mk4 golf I got for £200 and noticed the speedo is stuck at 110 any ideas on how to fix it?
Also the airbag light has recently showed up for some reason any help?

Thankyou

He didn't remove the original red. Literally just rattled can matt black straight onto the original paint work. Hes given it to me, and I want to restore it back to normal. Will a strong pressure washer do the trick?

Just looking for some commiseration, but I'll preface this with I am not a mechanic. I just like to dabble. Fixing stuff is a challenge to me.

So a while ago I had a coolant hose blow, led me to noticing the coolant was sludgey. Ruled out a head gasket (thank god) because oil didn't look contaminated. I think at some point the wrong coolant was added and/or my oil cooler is bad and is letting some oil into the coolant. So I do a coolant flush, run the hose through a bit then add a cleaner, get the majority of the gunk out. Along the way, I fixed the coolant hose that busted (crappy brittle plastic joint, thankfully just a straight connection)

Now it's time to replace the oil cooler, seems simple enough. I drained the oil, drained the coolant lines. I have the car up on jack stands, but not very high. I also don't have a creeper, so I'm just scootching on a dismantled piece of garage shelving on my back. I realized the clamps to remove the hoses from the oil cooler are much more accessible from up top. So I go up top, but some other coolant hoses are in the way. I don't have hose clamp pliers, so I'm fumbling around with a variety of other pliers to disconnect some other hoses that are in my path. I get the clamps loose, jiggle the hose to disconnect it...snap...freaking brittle hose connections! The engine coolant pipe T connector just crumbles at every connection, just like the other straight connector did. I spent way too long digging broken brittle bits of plastic out of the ends of 4 hoses and making sure none had made its way further in. So now I'm contemplating replacing all of the connections with aluminum. $30 on amazon, but I'm not sure the quality will be great...but at this point, it'll be better than it was.

So I let that be for now until I can get a replacement part. I decided the hose clamps on the oil cooler will be much easier to get at if I unbolt the oil cooler first, then I can move it around a bit more. But wait! I don't have a 27mm socket 🤦‍♀️ I have literal billions of other socket sizes, but not that one. Sooooo now I gotta buy that too.

And to top it off, I don't have a good shop light, so I'm doing all this with a little LED flashlight in my mouth 😆

I'm doing this because it's fun, right? 😖

Shopping list:

-already got an oil cooler

-hose clamp pliers

-creeper

-good shop light

-aluminum hose connectors

-27mm socket

-....? What next?

My 2.0l recently developed these codes after I repainted the intake manifold I've smoke tested the car through the brake booster hose, and found no leaks. It starts like it has a vacuum leak, with rpms spiking more than normal then dropping, there's also a slight hesitation on throttle.
Literally every engine sensor except the knock sensor have been replaced with the last 10k
Car has 180k on it
Ty for help
Extra note: the car recently had pcm processor faults they were cleared when battery was disconnected

Any guidance would be appreciated. Seeing lots of oil not sure why.

Hello, is there any major difference between 3 doors and 5 doors headliner? The cardboard on my beauty is gone and i need a replacement, but 3 doors are an hard find.

Thank you, and photo of the toy for refence

had my mk4 for about five months before the world decided it was wayyy to nice for me to own. so be it.

Looking for any advice for what I should do with suspension components. I need to replace my subframe, but don’t want to spend an arm and a leg. Anyone who’s done any sort of upgrades with LCAs or other suspension components there, what’s worth it? And are there any adjustability options outside of OEM that I should consider ? Any recommendations appreciated.

For added context, I’m on bags and have a rear stress bar and K brace. Thanks

Just picked up this 1.9 diesel auto with 185k miles. Smooth as silk gear changes. I’m thrilled.
