$1000 AUDI A4 — WILL IT START After 10 Years?

A couple months ago, I saw this Audi A4 for sale on Facebook.
Back when I was a student, this was my dream car.
I couldn't afford it back then.
I came from a modest family, so I could only dream.
Over time, these cars get cheaper, but I could never find an affordable one.
And then this listing appeared.
The car had been sitting for years, and the price was only $1,000.
Perfect for a YouTube project.
So yeah, I had to try.
And that's when I decided to meet the seller.
Back at home, the very first thing I needed to do
was completely clear out the interior to finally see the car's real condition.
I started with the trunk.
The owner had left me a few parts that might come in handy.
And once I pulled everything out, I could see the metal was in great shape.
No damage at all.
Just a horrible smell of dampness.
On the back seat, I found an Audi service folder with the booklet and the seller's business card.
A valve cover gasket.
A big official Audi service manual.
Some sensors.
An ignition coil.
And a few more papers.
And then I came across a damaged valve.
That really made me nervous.
Usually finds like that don't lead to anything good.
I had already noticed the coolant reservoir was empty.
And in the listing, the car was described as four parts.
There was also a set of cloth floor mats.
Brand new brake pads.
But only three of them.
And a surprise.
An old VHS tape for Audi owners.
One day, I'll have to dig up a VCR and see what's on it.
After clearing the back seat, it was obvious the mold had badly soaked into the fabric.
The armrest was moldy too.
But inside, I discovered the original Audi first aid kit.
In perfect condition.
I love finds like that.
Inside the cabin, there were lots of cobwebs.
Old and dense.
I checked the rear 12-volt outlet.
It was perfectly clean, which is good.
At least it means nobody smoked in the car.
But under the passenger floor mat, there were traces of some unknown substance.
And the smell inside was just awful.
That's something I'll have to deal with later.
It was a hot day.
Over 90 degrees.
So I set up my Eagle Peak canopy.
I've had it for about a year.
And it always saves me.
In the rain.
Or in the heat.
Best part?
It pops up in five minutes and barely takes any space.
You can't use detailing products when the car's hot.
So with the canopy up, I could work more comfortably.
I'd let the hood cool down, then wash the outside.
Meanwhile, I started cleaning the interior.
Then I looked at the coolant reservoir.
It was empty.
Another sign the engine's got problems.
Right away, I started wondering.
Was it overheated?
Where's the coolant going?
I checked the oil, too.
Yeah, it had oil.
It looked almost new.
Like someone changed it right before parking the car.
But still, you don't start an engine on oil like that.
We'll swap it out with a new filter.
I pulled the oil filler cap.
Underneath, heavy deposits.
And looking inside, some gunk and debris.
Weird.
So I figured I'd clean up the engine bay.
Check out the air filter after 10 years of sitting.
I've never seen anything like it.
It just crumbled in my hands.
Then I pulled the battery.
Under the tray was packed with dirt.
And a live slug crawling around down there.
By then, the sun had set.
The body was cool.
So I gave the car a wash, flushed the drains, and rinsed off years of dirt.
During the wash, I discovered another problem.
In some spots, the clear coat was peeling.
Even with the pressure washer on low.
That's what happens when a car sits under trees for years.
Sap eats through the protective layer.
And the clear coat slowly flakes off.
On the right side, there was a streak of tree sap.
I removed it with a dedicated cleaner.
But the stain still remained in the top layer.
I hope polishing will take it out later.
In the plenum area near the battery and the air filter, water was pooling.
The drains were clogged.
I pulled the water out with my old rigid shop vac.
I've used it for years in tough conditions.
And it saved the day again.
When I removed the battery tray, I found soil.
And even a worm in the drain channel.
Over the years, leaves had decomposed into dirt.
Not pleasant, but not surprising after such a long storage.
I flushed both drains with pressurized water.
And finally, the flow returned.
This is a known Audi issue.
If you don't clean the drains, the consequences can be serious.
Later, I'll lift the carpets and check whether any control modules got wet.
Before the first start, I removed the spark plugs.
Their condition can tell you a lot about how the car was treated.
I also added a small amount of oil into the cylinders.
To lubricate the walls and wake up the seals after years of sitting.
The plugs were carboned up and oily.
Most likely, the valve cover gasket was leaking.
I put a bit of fresh oil into each cylinder.
I also wanted to know if there was coolant left in the radiator.
I opened the lower drain.
And yes, there was.
Encouraging.
I topped the reservoir with distilled water.
About half a quart until it filled.
That means the leak is somewhere around that hose level.
Next step, change the oil and filter.
After that, we can try a start.
I connected a new battery.
Inserted the key.
The cluster lit up.
But the key wouldn't turn to the on position.
The car was in park.
The steering wasn't locked.
And still nothing.
I replaced the key battery.
No result.
After 10 years of sitting, maybe the key lost sync.
Or a module wasn't responding.
First thing to check.
Fuses.
I opened the fuse panel.
Some fuses were missing.
Some were installed incorrectly.
Why would anyone do that?
No idea.
I pulled them all.
Checked them.
Replaced the corroded ones.
And added the missing ones.
After that, the key turned.
And the cluster came alive.
Fuel was almost empty.
Which was actually good.
Less old gas to deal with.
I went to the gas station.
Bought the highest octane and a fuel additive.
Mixed it per instructions.
And poured in two jerry cans.
Now there was more fresh fuel than old.
Safer that way.
Before reinstalling the plugs, I cranked the engine a couple of times with the starter.
To push out the excess oil from the cylinders.
Right away, I noticed a metallic knock.
That worried me.
So I decided to check compression.
Cylinder 1 showed about 8 bar.
Not good.
Cylinder 2 was only 60 psi.
The rest were low as well.
By cylinder 4, it looked like the engine was done.
But when I unscrewed the tester, I noticed the threaded tip had stayed in cylinder 1.
That made all the readings invalid.
Annoying.
But also a relief.
Maybe the engine was healthier than it seemed.
I spent almost three hours with long pliers and an extractor.
Carefully pulling that tip out.
Then I cleaned the plugs.
Reinstalled them.
And prepared for a real start.
The sounds while cranking were unsettling.
But I had to keep going.
A friend stopped by.
So I asked him to watch from outside while I cranked.
If something went wrong, he'd see it immediately.
Try again.
Oh wow.
It's just oil dripping off the exhaust.
On the seventh attempt, the engine started.
It was a moment of relief.
The car was still alive.
Now I had a real chance to bring it back.
I let the engine idle for about 20 minutes.
Then I went out for a short test drive.
Just to check the transmission and the brakes.
But after only a short distance, I had to stop.
There was a strange noise coming from the left wheel.
I checked the wheel.
Everything seemed fine.
Then I looked underneath the car.
And saw two leaks.
And that knocking from the engine.
It was still there.
The brakes were rusty.
But as I drove, the rust began to scrub off.
And the discs started to clear.
They'll need to be replaced anyway.
But at least the car moved.
And the transmission shifted smoothly.
Back home, I checked the oil and coolant again.
There was a leak.
That's common on these engines.
Also, the cluster showed an overheating warning even with a cold engine.
So the temperature sensor wasn't working.
I needed the real numbers.
I used a compact top-down thermal camera that plugs into my iPhone.
It lives in a small case and is easy to carry.
The engine itself wasn't overheating.
But the exhaust and the turbo were running over 390 degrees Fahrenheit.
That's bad for everything under the hood.
For the ignition coils that already fail often on these engines.
And for the carbon hood, which had started to delaminate right above the turbo.
I'll add a turbo blanket and a heat-reflective film under the hood.
I also checked the brakes with the thermal camera.
Rotor temperatures help you see if the car is braking evenly.
Finally, I scanned the ECU for codes.
Here's what I found.
The engine had a list of faults and it was running rough.
I suspect ignition coils and spark plugs.
Faults in the braking system on the driver's side.
Safety system errors.
Maybe the car was in an accident.
The comfort module wasn't responding.
And the power windows didn't work.
We'll handle this in the next episodes.
My basic plan?
1. Fix the engine, the braking system, and the airbag faults.
2. Replace the timing belt, the chain with its tensioner, and the head gasket.
3. Replace all ignition coils.
4. Change every fluid and filter in the car.
The goal is simple.
Make this Audi safe enough to use every day.
