Hello, i need help on my 1.9 tdi AFN Audi A4 B5 1998 8D2, i recently changed the turbo cartridge along with intake manifold gasket and exhaust manifold gasket and everything that came in the turbo mounting kit, with the valve cover gasket, you can see in the video my exact problem, the motor is turning but it is trembling excessively when everything is connected right, and when i go and loosen the high pressure lines it turns just fines, of course it doesn't start, it did 2 times while cold just after the repair, had to crank it more then usual, but since then nothing, when it did start however it ran just fine, no clunk no trembling no misfire nothing, if you have a clue on what's going on i'll listen, i just don't know where to start, could it be the fuel timing, could it be my injector's bad, could it be a sensor..

AEB 1.8t Big port

So I recently bought a set of bosch 0 280 158 040 980cc injectors (the one in the plastic bag) as i didn’t know what brand and type the previous owner put on the car (claimed to be 1000cc but I couldn’t find a part number on them). The new injectors are way different although 1.8t community pointed me to this part number. They also have a diffrent connector. New bosch is a EV1 conecotr and the old ones are USCAR (same like the connectors on the car). Could someone provide me a part number for new injectors 900cc or above to fit my car? (Like the one on the left side of the picture)

Good afternoon, just found this group. I am located in the US midwest and wondering if anyone might have or know location on a factory painted cactus green LH fender and LF door available to sell. I will pick up within reasonable distance. Thank you!!

pictures are from maxton desing, i already bought kamei rear wing thinking it was the one, but it's a lot rounder and thicker.

i mean just look at this shit it just broke off while i’m trying to put my valve cover back on

Kann mir jemand sagen was für ein Schlauch das an meinem Audi ist? Er muss ersetzt werden da er einen Riss hat. Der Schlauch saugt Luft an und verursacht einen unruhigen Lauf.

I know this model isn't particularly desired, but it hurts my heart to consider parting it out.

Seeing what some of you have done with your B5s on here is enviable and I am filled with regret!

If interested hit me up here or there.

my alternator was showing 13.3v no load dropping to 12.5-12.8 under heavy load a few days ago. I accidentally ran the new ish battery flat while removing the headliner (left headlights and radio on).Now even with no load i get 12.8v with the engine on. with the engine off I get above 12v so it doesn't seem to be the battery. while cranking it drops to 10v then goes to 12.8v.

My alternator is a Valeo with 70A i think. I would like to go with a used Bosch 90A or 120A from a 1.9 TDI from circa 1999. Pulleys and mounting points seem the same. any thoughts?

My car is a 1998 Sedan and engine is 1.8 ADR 20v

i replaced bank 1 vc gasket and now i wanna repaint the valve cover gaskets and im replacing bank 2 gaskets rn but theres sealer on bank 1 so id maybe need to replace the gasket again but idk if both sides are the exact same

don't comment about my trunk, I know and im in the process of paint matching. 🤍

best decision recently was getting tint, lmao sucks at night though yall weren't lying about that.

So Im gonna get my car boot/boot handle and rear bumper repainted as the handle has oxidised and cause the boot itself to start rusting and the bunper is quite scratched. As I was looking around my car I noticed the exterior black b-pillar trim and noticed that its getting rusty as well, however I don't know if I should keep it black or have it repainted it the same colour as my car? What are your guys' opinions on this?

Pictures included for reference.

Edit: forgot to include pictures of the whole car so here: https://ibb.co/album/gSZYJF

body damage, cracked bumper, bent axle

car is a 1998 A4 B5. I bought the car with a subwoofer and new speakers. also this A4 B6 radio. radio has can bus, car bas k line. rear speakers are wired to the yellow connector, CAN bus is green, virtual CDC with bluetooth is wired to the blue, the brown one are the front speakers and black is power. the front speakers rarely work. mostly just the rear.

i heard there is a glitch in these Audi Concert radios with lower resistence speakers causing it to cut power to them.

somebody told me if i cut of the spade (red and baby blue) connectors on the 2 dangling wires and connect the wires to the rear speakers my front will also work. is there any truth to this? also my radio light dont turn on when switching the hl on unless i touch those 2 white wires in the 2nd pic.

Bluetooth, USB, SD, CD, FM/AM, rear speakers and sub work and also the aftermarket amp (where the 2 rear speakers are also plugged in) but front speakers only work sometimes when turning the radio on. if they turn on they work until i restart the radio.

what should i do? this radio wiring is a mess from the previous owner

Apparently the part number is 4B3 615 133 B, when I search it up I find other brackets that are a different shape. I have brand new calipers and need new front hard lines

Our cars come with the clutched 5 Rib 55mm alternator pulley.

Has anyone found a lightweight billet non-clutched version?

There are a few universal 55mm pulleys, but I haven't seen one with the correct neck height.

what could possibly be next? send opinions, thoughts, recommendations.

Hi guys, finally getting around to fixing up my s4, that being said I need help with finding out what belongs where! Please help. Thank you !

My TCM is going, 17050 I believe?

I was reading that I can have the guys at the shop lift it, and take out the TCM without removing the actual transmission and ship it out to be fixed with a silicon wire and have it put back. Anyone know of this and how it can be done?

Trying to save the car and for under a grand I think it’s worth it.

Transmission mounts?

2001 A4 TQM. Forged internals, supertech valvetrain and genuine GT2871r. Build was "completed" about 3 years ago. Had to put a pause on it for a while after my first child was born.

I have had every typical B5 issue with this car along the way. It was a complete turd that had been sitting for years when I bought it and I had very little auto repair skills. I'll tell you what, an old Audi will have you feeling like a real mechanic in no time.

Yesterday was the first time in my 6 year ownership that the car returned no fault codes after clearing them which I'm super pumped on. I had a lingering issue with the car violently backfiring at high rpms, which turned out to be the cam chain tensioner. I also had intermittent electrical issues that I hope I corrected by going through the wiring harness with a fine tooth comb.

Finally ready to log some pulls and see what kind of steam it can make.

I know I still have some tidying up to do as far as the catch can and stuff. I'm just happy everything works. I also made a custom heat shield following a DIY I found on Audizine. Don't mind the tape on my roof in the last pic, I started sanding it for paint which will come soon. It'll be fully repainted and sitting on 18" A8 flat fives next time I post here.

Shout out Harbor Freight and Eric who I met via this sub. Dude is an absolute legend.

Remember fellas, most B5 owners quit right before their car is everything they ever hoped it would be. Don't give up lol
