Uh oh, fix this '05 S4 or part it?

**suppressed** · 11-29-2022 10:07 AM

If you had a nice convertible 6 speed S4 w/97K miles that rolled across a field into a tree, would you fix it or take the parts for the wagon version?
The ultimate value of either is a priority to me. It doesn't have a salvage title.

Most other parts at the convertible are not usable for an limo or avant.

Depends on the damage i would fix it.

**suppressed** · 11-29-2022 10:51 AM

I meant the mechanicals. Find an S4 Avant with blown engine and auto trans or fix with A4 and S4 parts?
The tree missed the bumper mount and impacted the fender/tire and thus bending the suspension directly. The strut tower may need a slight pull, but is not known yet.
OP includes pics now. I had to startup a computer instead of a phone to upload.

The inner fender? And abs unit? Pretty damaged, doable but b6, what's it worth if repaired?

**suppressed** · 11-29-2022 02:24 PM

I'm curious myself, what it's worth repaired.

**Zolli** · 11-29-2022 04:26 PM

Personally, I wouldn’t bother repairing that one. Gonna be way to hard and costly to find body parts, IMO

**suppressed** · 11-30-2022 07:17 AM

Enh, it's an '05 and A4 body parts fit. The body parts aren't that costly. Paint is the expensive part.

**suppressed** · 08-20-2023 11:59 AM

I bought the car for 2k and I'm gonna take a shot at repairing it. I know a frame guy.

Inner wheel well has wrinkle damage.
I'm ordering cntl arms today to get it on all fours.

Where is a source of interchangeable parts with A4, wagon, etc?

Is the fender the same for A4 four door as this S4? I found a dead red car with fender ($30). Also, the radiator core looks the same as standard A4. Does anyone know if they're a match?

I need a hood and bumper cover. Are wagon pieces the same as convertible?

B6 convertible parts are all different, hood, headlights, fender (has a side strip on it) radiator itself can be the same.

Ah, yeah. So the fender does have that little bump strip on the side.
Thank you for that and the link.

Whole front end is different, the convertible has a different front radius.
Headlamps won't fit
Front won't fit
Fender won't fit
Hood won't fit
Grille won't fit
Bumper won't fit

Convertible is 8H parts nr rest is 8E

**suppressed** · 08-20-2023 02:20 PM

There's no LIKE feature, so thank you

So the wagon is probably not an option either.

Exact!
B7 is all the same, b6 is not, you need convertible parts.

**suppressed** · 08-24-2023 06:01 PM

It's sitting on all fours again. Three of the left control arms were bent. Two popped off the ball joints. The pinch bolt wasn't terrible. Took a little coaxing and whacking along with trans fluid and then Liquid Wrench.

The crash pulled the sway bar enough to break the motor mount. I guess that's next. The power steering reservoir is totaled. I gotta research what all used to be mounted in that front corner. The aux radiator is still there. Maybe some AC item used to be. Not sure if there's an oil something missing.

**suppressed** · 08-27-2023 04:06 PM

I want to prelube the engine before starting since it's been sitting for so long.
Can someone advise on doing that, please?

**Rol-co** · 08-27-2023 10:34 PM

Pull the fuel pump fuse and start for a few times 20 sec

**suppressed** · 08-29-2023 04:24 PM

Thanks. Waiting for a replacement left side motor mount bracket. $34, but then I saw one hanging under an A6 6 cyl at a junkyard which appears the same. Cntl arms were around $137. Gonna need a battery if the 1 I have doesn't retain a charge. I'm at $2.5k USD on the car including tow and assorted.

**suppressed** · 09-05-2023 02:20 PM

The bracket is replaced and the car runs well for the short time that I ran it.

It must be squirting power steering fluid from a hose at the destroyed reservoir.
Wondering if I can plug the hose temporarily without system damage? Anybody know?

yeah don’t do that. the fluid needs to keep moving. If you value your steering rack, wait until you can close the system up. if you start choking off lines and excess pressure starts building up you’ll start blowing seals in the rack and the pump.

Ok, yeah. Bad idea. I'll find the other line and patch them together temporarily. Just so the car can drive on and off the frame machine and trailer.

**Rol-co** · 09-05-2023 10:44 PM

I just buy the 30 dollar reservoir first, the ps is a bit sensitive system of the car, you wil get ten times more damage and labor if you don't.

**suppressed** · 09-06-2023 06:16 AM

Definitely going to. I thought it was a more sophisticated system about the reservoir, but looking at it in the link you provided, it doesn't appear so.

I recently replaced the whole power steering loop in one of my b6’s, it really is this simple.

Reservoir has been replaced and it's driveway mobile now.

That fast? In 4 hours?
Wy would you consider to do something else?

**suppressed** · 09-08-2023 12:12 PM

Under 10 minutes once I got the part there. It was $16 used. Already covered the reason. Because I thought it was a lot more involved and was just doing a temp patch. Thought there was more there than just a plastic can.

**suppressed** · 09-10-2023 07:46 AM

While researching the left side aux cooling layout, I found a video on youtube showing how to delete the right side aux radiator and water pump.
Is that commonly done without detriments? Do they do it to simplify, to utilize a fresh intake or to cheap out?

I'm green on the S4. Is it discouraged? I figured on replacing the damaged left aux water pump and rad..

Also, there is a problem with the linked renderings of components. I found the same coolant hose number for 2 hoses that appear visibly different. 8EO 819 378B. Both renderings show attachment to the side of the aux pump, so it's prob a non issue.
I can't find a rendering showing the hose connection to the top of the aux water pump. Any help on this? It shows the hose at the pump, but not how it attaches at the coolant system. The car is a bit mangled at this location, so it's not accurate enough to just swap parts, yet.

**Rol-co** · 09-10-2023 12:26 PM

It has a auxiliary waterpump? Or just the one at the engine.

You can look at the drawings here, pump and rad/cooling system are separate sections.

just fix the car before you start modding stuff.

Guess it has 2 aux water pumps and coolers, one per side. There are 2 rads and something that looks like an aux water pump is broken on the left side. The left side rad is damaged as well as what looks like part of an aux water pump. The right side has a rad, but I don't need to mess with that side.
I'm just trying to get it lot drivable now so repair places don't eff it up further.

Yeah those are the renderings that I referred to above. They aren't clear on where the top hose on the left side aux water pump connects to. Theres a SUPPLY and RETURN rendering. Neither are clear on attachment locale. There's a line but it doesn't make sense where it connects to. There are 4 hoses on the left side of my car. Two are radiator attachments. The other 2 must be coolant pump attachments.
Maybe I can figure it out if I can determine where the other goes, and I think I can.
It's a learning process. I'm new to the cars layout.

**Rol-co** · 09-10-2023 10:29 PM

Some first b6 S4 have an after run pump to cool down when the car is off but never seen one live, my car only has a rad on the left side with hoses to (motor) pump and a non return valve in it. (Plastic tube half way of the hose)

**suppressed** · 09-11-2023 06:10 AM

I'll get some pics today of what I think is the remains of the pump and the nearby lines. Sounds like my top pump hose is broken at the coupler which might have had the non-return valve?
That probably explains why the rendering is ambiguous, if all cars didn't have it.

**Rol-co** · 09-11-2023 12:11 PM

Pump engine
https://audi.7zap.com/nl/rdw/audi+a4.../1/121-121020/

Left rad, you can follow the lines to see where the hose goes, and 6 is the non return valve.

Passenger side, nothing to do there.

**suppressed** · 09-12-2023 09:03 AM

Ok, I think I'm done editing. Almost.

Here's the image of my damaged pump (right of hoses I'm touching and attached to the car body) and the presumed hoses that attach to it. Thru all this I'm understanding more of what the car had. But still, the previous owner removed several things so I can't know what was where, exactly.

If you look at hose 22 in the coolant layout, it doesn't really show how it's attached at the cooling system. That might not matter, but it doesn't show the non-return valve and associated. My car pic shows the 2 hoses that appear to be the pump hoses. There were broken nipples in both hoses though, so the attachments must've been thrown away or left in the field where the car hit a tree.

My index finger is touching an S shaped hose with stock number 8EO 819 378B which attaches to what looks like a heater pipe going toward the firewall, pipe 24? However, if you smash the hyperlink on the 7zap rendering of hose 22 it displays the same number 8EO 819 378B as is stamped on my S shaped hose. It's clearly not the same hose shape and my hose isn't that hose attached to the pump. It's not likely that it can even attach to the S shaped hose as depicted.
But SWAG to assume it's part of the assembly then I have to obtain that missing link to complete that part of the circuit.
I've yet to determine that they somehow attach to the reservoir downstream in a similar manner as depicted.

**Rol-co** · 09-12-2023 12:36 PM

The drawing is with and without the pump, you have a pump (remains) so follow that route, it should fit.

I would clean it up there and start over hose by hose, place parts first where it should be and last connect the hoses.

**suppressed** · 09-12-2023 03:50 PM

I wish there were drawings and details of the "with pump" set up. Because I don't see them anywhere. They just aren't there. The pump is. The hose layout and part numbers aren't. The one hose (22) shown as 8EO 819 378B isn't the hose in my pic on my car below with that number stamped on it.

Maybe I'll find car pics of one being parted to go by.
Thank you.

My car has a 900,000 VIN. The pic below shows my S shaped hose with number 8EO 819 378B stamped on it. That's the same number on a hose 22 in the drawings, so I'm kinda stuck at figuring it out.
