    Hey, again. 2003, 1.8T. Wondering if anyone happens to know roughly the temp at the flex section of the exhaust? Does it stay consistent over, say, an hour’s drive, or continue to climb? Mostly wondering if it would be safe to use an 850F wrap temporarily until I can get that whole section...

    Hey passatworld. I took my passat on a 2 hr trip today and we went over 2 mountains. When I was going up over the mountain I was running at like 3/4 throttle. It jumped off the 190 mark up to about 220-230 in like 10 seconds then went right back down to 190. This happened 2 other times on the...

    Any help on this will be much appreciated! 2005 Passat TDI Wagon - This all started after a bad alternator regulator which was producing electrical spikes read up to about 16- 16.5 volts on a multimeter. Whether this actually led to the tranny problem, who knows for sure. - After the...

    Hey all. I bought this passat 2002 1.8T tiptronic 6 speed (158.000 km) from a friend a few weeks ago, first time passat owner here. The other day I was driving downhill and this time I wanted to use tiptronic so as to not use brakes to control speed. By the way, my previous car was manual, this...

    I have a 2003 Passat and can't seem to "seat" a new coolant temperature sensor into the coolant flange. I purchased the new sensor, with new o-ring & clip, from VW. I've read many threads on it, and it seems like a fairly common problem. By the way, my old sensor wasn't leaking, but I think...

    I have been going through this 1999 Passat, AEB engine, and got concerned that my temp gauge never reached normal operating temp. 190 degrees if I am correct. So I took a reading with VCDS and found that the top temperature I got was 60 degrees Celsius which is around 140 F. My temp dash temp...

    Hi, I retrofitted a B5.5 FIS cluster (3B0 920 847) to my 2000 B5 Passat which originally contained an MFA cluster (3B0 920 922). I have changed the EEPROM of the new cluster to that of an MPH (3B0 920 947) and I have done the necessary soft coding and key matching. The cluster works fine...

    My 08 Passat 2.0T threw code P2181 which is Cooling System Performance Code but I could not pinpoint what exactly caused the code. P2181 Cooling System Performance DTC So I took the coolant temperature sensor off and found it has so much residue around its copper head. I replaced it. And then...

    I have a 2002 Passat B5.5 V6 and recently I've been having problems with the A/C - the temperature displayed is at first correct and then will start dropping to anywhere from -49 °F to 11 °F. It's now been constantly in that range for the past few days and never displays the correct value. I...

    Just curious if anyone might know the average running temp of the exhaust at the flex piece? 2003 B5.5 1.8t Thanks

    hi guys, last 8 months we are trying to figure out mystery. I already had it checked by three mechanics and vw dealership and no one can find any problem.

    I have a 2003 Passat 1.8T manual, AWM. Slight coolant leak that appears to be from the coolant temperature flange. I know the parts are ~ $40 from the dealership (it's a plastic housing), and the dealer is quoting ~ $350 for the job. That sounds like a good price to me. However, I'm...
  17. Volkswagen Passat B7 Discussion
    Hello everyone, nearly one month ago I noticed that the temparature gauge was low on my Passat B7 2011 2.0 TDI (bought in the european market) and there was no hot air inside the cabin. I searched over the internet and read that most probably it was a tstat problem. I went and bought a non-OEM...

    Hello, I just changed my thermostat -twice- and the CTS and I still get a temperature gauge that fluctuates depending on my driving on the highway. Any thoughts? Regards, Arber

    From reading the factory gauge has a range it uses to keep the gauge on 190. From monitoring the actual engine coolant temp I see times where it is above the indicated range, sometimes by 15 degrees. Has anyone else logged actual engine coolant temp and can share their numbers? Thanks.
