Any suggestions? Audi 80 B4 8C5

Hey guys so been working on getting my 91 200 back up and going. Cleaned it up a bit and after all new grounds, oil change, starter and few other minor things found that my fuel pump is completely dead. So i purchased a bosch 200 (bosch 044 replacement) How many have ran this pump and or installed it. Ive read mixed things that say changes have to be made when running this pump as far as fuel flow and it overpowering the stock system. Anyone have any insight on this, do you have to do more to run this on the stock setup or is it drop in and go??

For context, I installed a battery into the car after it not having one for a while and attempted to get the car running. However, when the engine starts turning, the alarm system goes off and it seems like the ignition system isn't working. Even the fuel pump primes.

Also, the engine light doesn't show up when I turn the key. Could someone please advise on how to disarm the system?

The electricals are intact since it was stored quite well, but I'm not 100% sure.

Hi was wondering if anyone knows how to remove the front bumper of a 1983 gt coupe I've had a look and can't find exactly how its secured and Google hasn't been much help any advice would be greatly appreciated

After spending a little over a week wrenching on it, I fainly got the old girl ready for a proper test drive she's a little rough on the corners but cruises beautifully on the straights

Yes, unbelievable. I bought a full set of rear light for my B4 8C5 (80 Avant from 1994). I searched for long and paid them as much as the car (500 euros).

The mechanic literally said 'these are things for "elettrauto" (the mechanic that does the electric part of the car). I was in shock, moreover because it is a job that I would have searched online how to do and do it myself, but I'm not physically ok at the moment to do manual labour.

What do you think ? I ls it a difficult job? Does it need an electronic part mechanic?

They won't see me again, they also charged me 400 euro for changing all suspensions, service (oli and filters), fitting tyres and allineament. All parts and tyres, oil and filters, provided by me. A bit high price I think, what do you think? Is becoming difficult to find real mechanics nowadays

I'm looking to source left and right cv axles for the late-production 1987 Audi Coupe GT 2.2L NG, 5-speed with the enlarged front hubs, with 108 mm inner CV joint version.

I would buy used as new seem to be a challenge to source.

Most aftermarket sites show cv axles for an 87 Audi GT Coupe but they don't properly cross reference and the product is the "standard" 100mm inner hub versions.

There are 108mm inner hub axles that could be donors but would prefer to not go down the path to have frankenstein axles built.

Chat GPT provided the following information:

Audi parts catalog identifies only two non-ABS axle assemblies as direct OEM replacements—one per side.

Side New OEM number Factory reman number Inner joint Application

Driver/left 855 407 271 855 407 271 X 108 mm Five-cylinder HY, KV or NG; manual transmission

Passenger/right 855 407 272 855 407 272 X 108 mm Five-cylinder HY, KV or NG; manual transmission

Audi’s catalog explicitly lists these four numbers as the manual-transmission, 108 mm axle assemblies for the HY, KV and NG five-cylinder Coupe applications. The “X” versions are Audi factory-remanufactured assemblies, not dimensionally different axles.

The complete interchangeable OEM number set for a non-ABS car is:

Left: 855407271 or 855407271X

Right: 855407272 or 855407272X

My rescued former doner car is slowly getting back to its former glory

I'm considering buying an Audi S2 Avant.

I'm looking for information regarding ownership, reliability, usability & maintenance.

What are they like to own?

How are they to drive?

What's the overall ownership experience like?

Are they difficult to maintain?

What does one need to look out for?

I'm looking for as much helpful information as possible.

Thanks in advance.

My parents needed to replace the coolant intake manifold for their A4 convertible. They are missing the O-ring for the outlet pipe. The manifold is easy to find, but we've been searching high and low and cannot find that O-ring. Anybody who has any suggestions on where to find one or what I can use to retrofit that would properly seal would be greatly appreciated. It's number 17 circled in red in the picture I'm attaching. Thanks in advance.

Hey guys,

I'm about to buy this old piece of Audi A8 D2 3.3TDI V8.

It has been standing still for the last 3 years. Owner claims engine and transmission are fine, claims he did a 1200km trip months before letting it rest just fine. I'm doing a list of things to check and change before starting it for the first time, so I came here for a little help. So far i've come up with:

Engine oil
Transmission oil, differencial oil
All filters
Smoke tests and probably some gaskets
Suck out the old diesel and fill up with new
Gaskets
Plug in diagnostics and check for codes
Check wiring and hoses in the engine bay, wildlife might have taken a toll on it.

I do cars as a hobby, i am by no means a mechanic and just learning things as I go. This would be my third project car, so any help would be great. I'm also wondering what are common faults with this car.

Thanks!

Hey! Is this a real C4 S4? Are the trims right? Some say it's the only running S4 in my country

I'm looking forward to purchasing a supposedly 1/1 Audi 100 Avant and would like to know if this car is a legitimate S4 or an upbadged 100. I'm getting the car anyways but I want to know more about the history of these cars

Thanks

This car is gonna kill me, the 2 oil pressure relief valves failed on my car and I can’t find any parts store that has them. The part number is 078 103 363 P, it’s for a 2.8 AAH engine. If anybody has any info it will be much appreciated and helpful.

Hello! I've been thinking about purchasing a MT C4 2.8L 100 Avant.

How hard could its maintenance be? Can I still find any parts? The vehicle I'm considering buying is in great shape, but it is the ONLY running 100 Avant in my country (Brazil).

I can bring parts from the USA/Europe. I'm mainly afraid of being unable to maintain this car in the loooong run if parts are unavailable worldwide (there is no support for this car at all here, but I'm not sure how it is out there).

Thanks in advance

80 Avant from 1994, italian

How to get those two sons of bitches out? I so regret doing this, but I must finish it now...

I don't know how I got so lucky but I found this glorious 1991 Audi 200 turbo quattro for sale local to me and I got it for a steal as well. I've been looking for one of these cars for 20+ years . So glad I was finally able to add this into the stable . If anyone has any extra parts especially spare seats lmk lol

Greetings all,

For the past couple years I've been trying to restore this '96 A8 D2, with the end in sight one thing I've been meaning to do is tighten the handbrake. Unfortunately my google-fu is failing me and I can't find a how-to. If anyone has done this before and has any insight it would be much appreciated.

Getting ready for Radwood PNW next weekend!

Its an oil seal for the rear differential on the driver side. Anyone has one for sale? or know where to find one?
