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:
S4's EGT Sensors Finally Replaced
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 convinced 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....
