Audi RS2 -94 Swe

[k.alle]

I bought a 120A alternator for AAN on german ebay for ~140€ incl shipping to Sweden a couple of years ago.
It came as a Bosch refurbished item.
All local resellers wanted ~7-800€ so it was a good deal.

Just like s0_big I just swapped the pulley to ABY and the back cover.

Any idea of the manufacturer of the new alternator? I just recently rebuild mine and also thought that the 120A version is hard to find.

No I couldn't tell the manufacture. Only the numbers on the first picture.

About a week ago i was out for a drive when suddenly the charge light for the generator light up in my face. Voltage meter in the center console always was a little up and down, but i thought it was some problem with the gauge. This time the voltage just dropped lower and lower until i had to stop the car..
Dismantled the generator and left it to a electric shop. They told med that the "diod bridge" was shot. The price for refurbish was the same as for a new so i let them order a new one for me (I thought it was hard to find new replacement generators). This is same spec as original (120A).
Today i changed the generator, fitted just like original. Immediately the volt meter showed a stabil 13-13,5V with lights and full AC etc. What a difference it made. Fan for heat/cool the inside was much stronger, now the AC really feels good inside..

Old vs New generator, just had to change the pulley.

New generator fitted, well it's not painted like the old one, but hardly no one sees it anyway. (and i didn't want to dissassemble just to paint it).

Nice work. She is looking really good
It's probably the foam on the flaps breaking down.
Not a pleasant job. Dash out I'm afraid

Yeah, noticed that some people had problems getting heat from the heat exchanger. So why not the same with the cold? That sounds like a boring winter project..

AC filling/repair was succesfull. The car held vacuum for 4 days, so the system is tight, atleast with vacuum. Drove to my old collegue that used to work with refigeration systems and vacuumed some more and then filled the system. According to the plate, the system should hold 750gr +-50gram of refrigerant R134a, we could only fill about 500gr even though we heated the refrigerant bottle and had vacuum in the system.. But atleast it is working. Strange thing is that the regulation from the climatronic panel is a little funky. When i use the windshield button i get more cold out of the vents than if i run it on auto. Maybe something to do with the flaps inside the ventilation? Will look in to it deeper later on, but now i have a cold inside and i'm happy with that. Sun is shining in Sweden and the car takes a sun bath. Tomorrow we will take a longer tripp some were and have lunch and iscream !

Yes, the S2 also has it.
I renewed it on mine after some mice came to make nest in it.
Got it from AT as well. It was a funny package to collect at the local tobacco store.

Don't have the part number on hand.

As my AC refill didn't go well and there was a leak at a pipe between the drier filter and the coupe i had to change the pipe. Luckily Audi tradition had this pipe. Today i changed both the pipe and drier filter. Front bumper and inner fender had to come off then it was pretty much room to change the parts. O-rings looked good so i didn't trouble with finding new ones.
Then i connected my borrowed vacuum pump and let it run for about 20min. Closed the vacuum pump and watched the vacuum gauge for an hour, no leaks. So tomorrow i will refill the system and hopefully the AC system will work without any more problems!?
I was so busy with working i forgott to take pictures after the change, but here is some before i changed the stuff.
Will tell you tomorrow if i have working AC or not..

Pipe that had a hole, underside of the pipe, looked like a stone chipp:
