Long time, no update! I've just been driving the coupe on nice days, but I'm glad to see Spring is here. Last weekend, I put some new wheels and tires on. I go back and forth on black wheels, but I still have them for when I might want to switch it up again.

So, it appears that the new lifters resolved the noise issue.

As for the issue I had with the cam caps being on the wrong side, it seems as though the engine is doing fine. I don't know if this speaks to the quality of Audi's engineering or just dumb luck that the caps were close enough on both ...

Going back together...

Over the weekend, I was able to check the rotation of the cams with the caps installed correctly and no lifters. Everything seemed to rotate just fine. It's back together and I have rotated everything several times to check the timing. I ran out of time, but I should be able ...

So, I started digging in to replace the lifters and found something bad. After removing the valve cover, I discovered that the machine shop I used put the cam caps on the wrong sides. They are in the proper order (front to back) and in the correct orientation...just on the wrong side. I am so mad at ...

Merry Christmas and Happy New Year everyone!

Here are some updates from my time off for the holidays. Gave the coupe a real wash for the first time in a long time. Hoping to take it to the local C&C this weekend if the weather looks good.

Another issue found and fixed. I noticed I was losing some brake fluid and it was showing up at the bell housing (best I could tell). I bought a new slave cylinder when I bought the master cylinder. Guess I should have just replaced them both together.

Got the new slave in this afternoon. I was a ...

After receiving the clip from FCPEuro, I got it installed in leu of the makeshift hose clamp I was using. I also adjusted the pedal so that there is only the slightest bit of gap between it and the stop on the floorboard. I also found the clip that helps keep the cable in the throttle cam on one of ...

Well, it turns out I did have some slack in the throttle cable. I have the correct clip on order from FCP Euro, but this is holding it for now and I'm able to go WOT. Boost pressure is around 13 psi now. It's like driving a totally different car when you have full access to the go pedal.

https ...

New knock sensors are in, but my boost gauge is still only getting up to about 7 psi. I did disconnect the battery and remove/replace the two ECU fuses.

The engine seems to run much smoother and is more responsive. The DTCs have gone away.

Next up, I was planning to check for boost leaks again, as ...

My seat choice is not everyone’s favorite, but this update is one of the reasons why I’m went this route.

My original seats were pretty worn. Not the worst I’ve seen, but not good. I have them stored in the shop because someday I may have them recovered, but we’ll see.

I was considering some ...

Hooked up the VCDS again tonight and the DTC for the knock sensor came back (as expected). Got a picture of it this time. Hoping the new sensors get here from FCPEuro soon. It’s tight in there, so hoping I don’t have to remove/unhook to many things to get to them.

I also ran the output test from ...

I've been driving the eS2 a little bit more, lately. Have noticed that it can only build about 5psi of boost, though. I was seeing 12-13psi before. So, I hooked up the VCDS and it had a DTC stored for am open/short circuit on one of the knock sensors. From searching the forums, this could cause the ...

Lately, I've been having intermittent issues with the clutch pedal dropping to the floor. I could pull it back with my foot and it would continue to work fine. The situation didn't improve after reverse bleeding at the slave cylinder. After searching the forums, it seems as though the master ...

Was able to get the lenses swapped. I decided to do both together to avoid having a mix of old/new and Hella/Valeo lenses on the car. The new are Valeo.

Well, I finally have got the AC working with the swapped 3B and B4 manual airbox/controls! In the 14 years I have owned this car, it has never had AC...which has given me very little desire to drive the car in the Oklahoma Summer heat. My kids are still traumatized from some of the times I drove ...

Those look nice! I’ve thought about getting some bronze wheels before. I think they look good with the pearl.

Was hoping to get the new AC compressor installed over the long, holiday weekend, but it got delayed in transit. I was able to install the freshly painted bumper that i picked up from the painter last week. Pearl white is so hard to match. It's not a great match to the rest of the car, but it'll do ...

This is not what I wanted to see when i put the CQ on the lift last weekend. I have a couple spare AC compressors, but I bit the bullet and bought a new 4 Seasons unit for about $300. The Denso compressors are in the $800-$1000 price range. Just have to transfer one of the manifolds over to it. And ...

So, back in April 2021, I was in on a group buy for some aftermarket windshields that were to be imported from Europe (Finland if I remember correctly). About a year later, they showed up in the states and were being stored in Asheville, NC. Since it was proving impossible to find someone that would ...

So, I had a good day in the shop yesterday and was able to wrap up the wiring for the AC controls. With a jumper in place of the low pressure switch and the key in the ON position, the AC button now activates the AC compressor clutch!

Next up is to tighten up some of the connections on the ...

Just when you think you've got it all figured out, you find that Audi is using a non-standard relay for the AC clutch control. So, if you're trying to follow along, disregard what I wrote in the previous posts. Good times!

It turns out the AC clutch relay has a PNP transistor in it, along with some ...

I feel ya on that. It was a pain to try and rebuild some of my threads with good pic links when I switched from Photobucket to Imgur.

It turns out, only 3 wires needed to be spliced...power to the AC clutch relay, low speed fan relay, and the ECU as a signal to increase RPMs. All of them are fed from the same #1 terminal on the AC switch. The airbox gets its ground from the plug connected to the blower controls and that plug is a ...

One question I have is, should I pull a vacuum, check for leaks and fill the system before messing with the wiring? My thought is, even if I get the wiring right, the compressor won’t kick on without pressure in the system, due to the low pressure switch. Unless, I can temporarily jumper the low ...

Do you have the manual box and controls? if not, I can send you mine, I’d just have you cover shipping. I only kept it in case I couldn’t get the auto stuff to work.

I have one that came with the manual airbox. It seems to be working fine, as I can control all ...
