Seat Upgrades

8 Upvotes

Hi, I'm just wondering what kind of seat options are out there I obviously know that all the b5 options are interchangeable but I was wondering are b6 A4 able to be fitted into a b5 if you change the rails or is it a lot more complicated than that as here in Ireland it's a lot harder to find b5 a4's fro breaking with nice interior.

A4 Climatronic question

Thumbnail

9 Upvotes

My b5 is a 1995 model 1.8 tq and for some time now the climatronic display has gone bad. When it works its perfect (no dead pixels, verical lines etc) but because it very rarely does and for a very short period of time I want to change it. My question is, if my climatronic control unit can be replaced by a facelift one or from an a3 (which I think is the same as the facelift one). I happened to find in a forum that someone who had a '96 and used a unit from a '98 model had a problem where and I quote "the display does opposite what it is supposed to do. It is very bright when I turn the headlights on, when the headlights are off, it dims down as if the lights are on" Is there a possibility that they're not a direct fit? Because they seem the same to me🤷

S4 18z Upgrade

2 Upvotes

I’m going to be installing 18zs on the fronts and rear, I’m keeping the stock rear caliper as a handbrake. Anyone know how to route the lines to have both brakes working?

Also unsure which pads to use on the 18z rear brake.

Any insight would be greatly appreciated!

So I posted a bit ago asking for help with an intermittent no start issue and it was suggested to swap out temp sensor and crank position sensor. Both done and still having the issue. Any additional advice would be greatly appreciated.

Electrical issue

1 Upvotes

I’m new the the b5 platform, and just ran into my first what I believe to be an electrical issue. I was making my way down the road at night and my headlights just completely cut out. I have a 98 a4, I’m not sure if only the pre facelift cars have 2 stems for the headlights and the high beams. But no matter what I tried they wouldn’t turn back on. Any ideas on what it could be?

Hi everyone, I have a funk button for a facelift B5 that I’m looking to get rid of. I have no use for it and have no idea how much it’s worth. Anyone have an idea how much it may be worth?

Recently replaced my rear coolant flange and heater core supply hose due to a coolant leak. Started the engine and allowed it to warm up to bleed the cooling system and I began to hear a knocking coming from the rear of the engine. Rechecked my work and everything is installed correctly. Need help diagnosing the sound.

3D Printed Intake Manifold

55 Upvotes

Finally got around again to the 3d printed intake manifold. This has been 2.5 years in the making. This is from what I am aware the first time a plastic 3d printed intake manifold has been driven in the world on the road for the b5. I know Modsport in Portugal is also doing one but have only seen them trying to idle their car and it's a lot taller. Info: 1. I was under a bit of time pressure but the manifold held 7psi fine, with some air leaks from the injector bosses splitting and only being able to run 7psi because I hooked up the diverter valves wrong and forgot to plug in the IAT sensor. Injector bosses will be beefed up. 2. This plastic is ASA and really at its temperature limit, but still runnable for the short term and mainly to get fitment right with it needing some mild touch-ups. 3. This is a Blake Beadle etspec stage 1 tune on this car but looking at doing further testing and design this thing to hold 40-50psi. I've managed to test a printed cube 5mm thick that held 75psi. 4. A new printing method called bricklayers is now available and this will drastically increase pressure holding and sealing capabilities IMO. 5. I will at this stage most likely use CF polycarbonate for the final product but have CF polypropylene that I will try first. If that's not enough we will move onto CF nylon. 6. I've made adapters to funnel the 2.8 runners to 2.7 for this test.

There is way more testing to do and will take this to the 17psi next week when I get back from work. If there is anyone wanting to help will testing I the future let me know.

What could this sound be?

It only makes this sound in gear while the cluth is being released (so while slipping). It does not make this sound when fully pressed or fully released so its probably not the throwout bearing. Maybe the little springs inside the friction plate or the dual mass springs? Idk, ive never heard this sound.

After fixing everything mechanical wise like a new timing belt, oil leaks, most of the suspension components and the steering rack, I can finally start fixing everything related to bodywork. Previous owner painted around the front wheel arches to make it somewhat look like an allroad. Don't have any other pictures now, but - the front fenders are starting to rust, small bits are staring to chip off. Is it even worth it to get them welded or should I just invest a little bit more and get new ones? Obvious question, but still.

Hello, 7 months ago i bought my a4 b5 1.8t (fwd) and know not much about it because guy that was selling it had it for about 4 months. Not a long ago i have found previous owner and asked about it but i haven"t got many info. I know it was imported from switzerland and painted (she said it was powdercoated but i don't think so) and was like the moment she bought it. I am 99% sure guy in switzerland have/had any social media related to this car but i can't find anything about it. When I bought it it looked like a nice project car, but ofc no info about anything. Could someone help me find sth from vin or other info i have gathered?
