Great work on keeping the site up and running, but one thing I've noticed: it seems that some service manuals are now missing? Looking at Q4, for example Q4_wiring directory is completely empty, and I think there have been more folders available for the Q4 previously, including some service manuals,...

Yes correct, my bad as I wrote of the top of my head.

My point still stands though, not directly useable.

I'm planning on doing mine with 330x32 mm and 166 4 piston calipers as described above but probably earliest next year, so can't help much more other than dropping an idea until then

Yes! :D Just successfully mounted the front 2.0 TS discs after re-drilling and can confirm full success. Dimensions are exactly the same, just the bolt pattern had to be tweaked but that is not an issue. I've used locally manufactured discs as an experiment before ruining a pair of eexpnsive discs, ...

I know of a few guys who tried it, and I will be looking to do just that as soon as my front rotors wear out :D From what I heard, you want 166 4 pot calipers and 330 mm brembo discs from GTA. The discs are 32 mm thick compared to 166's 28 mm so calipers need to be widened but still far easier and c...

Interesting topic, electrical gremlins will be more and more common in our cars after all those years. Not sure if you have the ignition modules integrated in the ECU or as separate units by the radiator, in such case worth checking. From what I can tell, in my Q4 wiring was toast to the injectors a...

Thanks, I also found the ones from Alfisti in the meantime so I'm a bit torn between getting those, or re-drilling the TS-ones. TS-ones I can get for ca. 50 EUR a set, drilled or slotted rotors as well if one wishes such a thing. Then re-drilling the bolt pattern at a local machine shop. I've got th...

Resurrecting this old thread as I'm in need of rear brake discs at the moment. Did anyone find a good solution to this problem? Looking for a place in Europe before I hit Alfissimo from overseas, also if possible for a cheaper option (considering adapting TS front rotors as well). Arjen, where did y...

The first one which goes into the reservoir I got about 2 years ago brand new from an Alfa dealer, go and ask, they may still have them (comes together with a new spring too). The second one in the Viscomatic group is N/A anywhere, I've tried contacting the supplier even (Microfluid), but they don't...

I've been through the head gasket situation myself some time ago as you recall... I can only cheer you up by saying that access to a lot of other components will be much easier with the heads off, so good time to have a closer look at the steering rack, starter motor, gearbox linkage bushings (highl...

No way! :mrgreen: What a great find! And the price is a joke... :mrgreen: Very lucky you, congrats! I was not aware about the Zender springs at all... looks very promising, can't wait for the final result. Good to see the work progressing nicely, you're giving a bit of motivation to all of (more laz...

I believe that would be worth watching for you Allan, Harry's garage just did an episode on the 8.32: https://www.youtube.com/watch?v=y3rHl4DH-fY

Great news

Keep us posted about the progress on other items too, I'm interested to see if the springs you found will lower the car slightly. I actually think 1-2cm lower would suit it very well and would look into that myself.

Wow, that's wonderful news! :D Looks like the ABS unit itself proves to be quite reliable, and Alfa engineers should have included this simple step in the debugging instructions too! Would save everyone a LOT of trouble. :mrgreen: Thinking about it in retrospective, this fuse looks like a total afte...

It's been a while since I posted in this thread, not much time to recap everything I did on the car, but I do keep a spreadsheet with all completed repairs. :) I decided to post here since I've achieved a significant milestone of having no warning lights on my dashboard (at least on startup), after ...

It sure looks clean! Nice work, and thanks for the detailed photo documentation! Good to see such a dedicated rebuild.

What did you use to clean the engine block and other aluminum parts? Was it media blasted? It looks brand new, must be very satisfying.

I will be wiring it all together shortly, waiting for the PWM module to be delivered now. Can you tell us how did you wire it to the proportioning valve? Looking at the diagram, I see only 2 pins there ( http://alfaromeo164register.com/manuals/Q4/Q4_wiring/Q4_-_Viscomatic//Q4_-_Viscomatic_Page_03.jp...

Update on this from my side. I am able to recondition the mechanism which slows down the flap. I renew the rotary damper with new fluid and better seals, so that it's not leaking anymore (thicker o-ring and casing is then glued together after putting new oil inside). The action of the damper is bett...

It's tears of joy let me tell you. :D I've just been testing the system with my Marelli tester, ran the pump motor test and the solenoid valve actuation test a couple of times to flush the old fluid out, and the system is blocking and releasing the wheels and pulsing as it should. Very satisfying :!...

What a shame that Totallyalfa does not offer the tools any more. :cry: I've been sort of waiting for a good moment to get a full set for a couple of years now, but did not expect this to be discontinued. That said, I know from my trusted Alfa workshop that they use more contemporary tensioning tools...

I was not expecting to say this, but... I FIXED IT :!: :!: :!: :!: :!: Finally, after many years my ABS light is going off after initial checkup! I could not believe it when it first worked. :D The diagnosis turned out to be somewhat misleading. What was ultimately the culprit was relatively straigh...

Hi Daryl, we've touched base on this topic here: http://alfaromeo164register.com/viewtopic.php?f=26&t=1869 but without conclusion. A couple of guys here had the lines re-done but we don't have any sort of template out of that. I'll be looking to do mine next year as well, I was planning to describe ...

Results: - I am measuring ground when the screw leading power to the pump motor is screwed down (this I suppose is short to ground, it's not supposed to be shorted, but I may be wrong) - Because of this the measurements are split into 2: with the screw in place (would be normal operation, but I fear...

So here are the mappings I've done between the N51 group and schematic. You can see which diode is where in reality, diode labeled by me as 4 and 7 are not visible. There is also my crude hand drawing, where you actually can see what is connected to what, I will try to digitize it when I have time. ...

Long time has passed but I will be posting an extensive update on the thread very soon. I did a lot of measurements which will be helpful for everyone here (for example I've mapped all components from the schematics to the actual physical unit, so I know what is where exactly and how to measure it f...

So just to recap for anyone who may run into a similar issue. What fixed it in the end was getting a brand new high pressure Viscomatic supply hose (the one after the pump) 60605589. Expensive, but worth every cent. Most probably the replacement I had made had insufficient flow reduction and caused ...
