I used the projected fog lamps that came stock off a MK3 Jetta GLX VR6. No, not my old car, but my little brother's car as he was donating it. His car had seen better days so I took what I needed before it was towed away. 

Eye'ing the MK3 fogs and a spare set of stock B5 S4 fogs I had, there looked to be some possibility to making it work. Obviously I'm looking for simple functionality because the 3000k HID's I have in my stock fogs now just weren't being used to their full potential. 

First time in years I can finally say... my S4 is error code free! Fixed a recent misfire and replaces the bank 2 sensor 2 O2 sensor. My Evap Purge Valve was acting up, but I put some Seafoam solution in it and to my surprise that cleared up that code. Let's see how long this last....

**Update 11/30/2012**
Ok well that didn't last long... just got a new code for the Bank 2 sensor 1 O2 sensor. I knew I should have replaced both. Oh well I was just trying to get past emissions at the time so another fix for another time.

If it hasn't happened to you, it will some day. Our cars have a weak point with the headlight washer pump that causes all of the washer fluid to leak out of the system. Likely it's related to removing the front bumper from over the years... not sure. Anyway, since I would rather not wasting my money on filling up the washer fluid once a day, I just let it go dry. The down side is that everytime I start the car I get a chime and Mount Saint Helens like animation goes off in the cluster. At the time I discovered the leak and found out how involved it was to get it fixed, I figured I could live with the washer fluid warning light.... 3 months later I'm getting sick of it! I know, "just fix the leak", you say, but replacing the EGT's was just a pain in the a$$ and I'm a little low on motivation and cash.

So I did a little reading online and came up with a idea, I'm sure I'm not the first, but I didn't find any exact D.I.Y.. Sorry no pics as I did this about 5 mins prior to leaving for work this morning. Steps below the break:

Finally replaced both my driver and passenger side EGT Sensors. One was completely dead and the other was having intermittent issues. 

Passenger side was easy to replace, but the driver side was not fun... not fun at all! I'm convienced that there is some sort of speciality tool to get it out. I'll put it this way, it took way longer then the suggest 2 hours. Even with help from my friend Erik from I.P.M. Auto Service, it took a while to get it out. I hope I never have to replace those again.

Last on my list to replace is the Bank 1 & 2 Sensor 2 O2 Sensors. Those are the very rear sensors that you can easily get to from under the car. And finally replace a leaking EVap Purge Valve. Again another easy fix when I get the parts.

I can say that the car pulls harder with the EGT Sensors replaced. It's still hitting the same boost level but likely has a better air to gas mixture. Not really sure as I'm no expert. I'm still running into issues were the car will do this randomly and light bucking/surging when on partial throttle. Very noticeable going down a slight hill with the cruise control on. Already replaced the TB and now the EGT, so I'm running out of possible causes for it. Maybe there is bad motor mount allowing too much movement. Or a ICM is going bad. Not sure and I don't want to throw parts at it. Need to do some more research and testing....

If you've seen my car in person there likely one thing you've noticed is my low hanging exhaust piping. Not a subject that I've wanted to talk about as I could have likely gotten it fixed a few years back, but I really did not like the place that I went to. When my wife noticed it a few weeks back I knew it was time to get it fixed.

So I went to a local muffler shop (mufflerkingperformance.com) just down the road and had them fix it. Told them while they were at it to go a head and remove the resonator as my exhaust just seemed too quiet for my likely. I don't want to wake up the neighbors... but I still DO want people to hear me as I'm passing them at full WOT!

Anyway, two hours later and for $120 my exhaust was finally the way it was suppose to be. They replace the piping from the cats to the muffler. Now I just need to clean it up and give it a wash, polish the tips, and likely take some steel wool to get ride of a little rust around the old welds. I'll give it a few months and will do a new videos so you can compare the sound difference.

I've been wanting to convert my brake lights to LED's for some time now, but simply the technology was just not there yet. I did replace the bulbs for my center brake light in the window some time ago which has worked flawlessly ever since. As for the actual brake lights it was going to be a little bit of an investment. This bulbs aren't cheap. About $17 a bulb which will likely to out last my car. As always I went with Superbrightleds.com. I order two 1157-R3X1W bulbs. 

If you've been following my blog for a while you know we don't get snow often in the Seattle area. Well, we finally got some and of course I'm not going to miss my chance to take the S4 our for some fun... I'll add more picture later this week.

Also I'm still looking for a hood. Let me know if you got one for same that is the same color. Thanks!
