  1. OK, after much additional testing, I managed to get the coolant temp (per freescan) up to a max of 102C, but no higher. Took considerable effort to get that hot too - long hard driving followed by barely moving at all in traffic then idling in the driveway for the better part of a half hour. Given how hot it is outside right now I figure I'm in good shape @102C. Let me know if folks think differently. Now I'm on to other issues, such as window seals improperly installed by dealer jamming up the window travel and why many of my gauges read the wrong values... Thanks!
  2. Had the exact same problem about a year ago. The local dealer said it would require rather expensive fiberglass work to repair, and even then it's just patching the crack, not actually solving the problem. Ended up making a sheet metal piece contoured to the fiberglass surfaces extending a few inches either side of the mounting bracket shown there, bonded it to the existing fiberglass, drilled holes for the existing studs there, and mounted the bracket to the sheet metal piece as well. Theory was to distribute the force from the window motor over the contours in the fiberglass, which of c
  3. OK, cleaned radiator fins last night. I am absolutely amazed at the amount of crap that came out. What a mess! I took the car our for a good long loop on the highway, then around town for 15 minutes at low speed, then sitting at idle in my driveway for 20+ minutes. If it was going to overheat, I imagine that would do it. Coolant temp never read above about 92C (which shows as 72C on my gauge, since it reads 20 deg low...) Granted this was at 7pm so the outside temp wasn't at max, but my drive home generally occurs at 6:30pm and it certainly had no trouble overheating at that time previ
  4. Checked the overflow tank, confirmed it has the right cap. So caps are s/b OK all around (assuming the spung cap is holding the appropriate pressure). Didn't have time to drain coolant or clean radiator fins last night so that's probably tonight's project. I am fairly certain that the problem is not caused by air in the system. When coolant reservoir was replaced we went to great lengths to ensure no air in system, including tilting car, vacuum-bleeding, etc. I'll see if I can pull thermostat tonight as well. Have had thermostats fail before in my daily drivers but in those instanc
  5. Good point about the oil temp, although I suppose there's another bit of info along those lines that I hadn't really considered... Using the infared thermometer on the front face of the oil coolers I found them to be 80-85C when the gauge read 100C. I kind of blew it off at the time, thinking I would focus on the things that were actually hot. I wonder if the oil temp gauge is reading high? Given that every other gauge seems to be having issues I'm not sure that I can assume oil temp reading is correct either...
  6. Good points Jonathon. Pressure cap only when cold is very good advice. The cap on the engine bay tank is definitely a sprung cap. Have had that one off enough times this last weekend to know that for sure. I'm not familiar with the wheel arch expansion tank you refer to... Which side would this be on? And is access to this tank gained through the wheel arch? Have had coolant in and out several times with the reservoir replacement, but that's not an entire system flush. Clearly some coolant is circulating since radiator is scorching hot, but how much circulation could be anot
  7. Hi all. I have a 94 S4, and it seems to be overheating. I say seems because I seem to have several semi-related problems... I live in Texas, so it's quite hot out. High running temps aren't that unusual from what I've seen. However a few weeks back I started having a problem where oil temp would reach 90+deg, and oil pressure would read so low that the oil pressure telltale came on intermittently. After much panic about low oil pressure, it was determined that the oil pressure gauge is just reading low - a mechanical gauge showed pressure to be OK even at high operating temps. So a ne
