  1. 2004 Passat 1.8T Coolant Leak Under AC Compressor

    Volkswagen Passat B5 Discussion
    My Passat is still in the garage they ordered the flange but still waiting (about a week) on the o-ring seals for the heat core pipe and flange the VW dealer only supplies them. I'm not sure why the seals are not included with the coolant flange as a kit. They said there was another leak under...
  2. Passat 2003 coolant hose leak?

    Volkswagen Passat B5 Discussion
    Hi Ellie, That's about right $980 is what the local independent auto shop charged me for a new water pump, timing belt and timing belt cam bearings, thermostat, thermostat housing and antifreeze. It's about an 8 hour job if labors about $100 an hour plus tax. My first water pump seal failed and...
  3. What did you do to your Passat today?

    Volkswagen Passat B5 Discussion
    I replaced my headlight units with cool black ones it was a fun weekend project but a pita to drop the front bumper too get both headlights out. Reinstalling everything was pretty easy just took a little time and patients with all the little torque drive bolts. After it was all done my Passat...

    Volkswagen Passat B5 Discussion
    I have a 2003 VW Passat 1.8t with a cat back exhaust system and previous owner removed the catalytic converter. It starts up and idles good no misfires but when I'm accelerating building boost the engine starts too surge and rev up and down like the boost controller is pulsing the waste gate...

    Volkswagen Passat B5 Discussion
    Well, that's a bummer lol there should be door locks on both sides. I was thinking of that too going through the trunk I could get a valet key made by a locksmith for half the price.
  7. No Heat Low Engine Temp On Gauge

    B5 Garage
    Ohhh ok thank you FrescoGreen01.5, I have manual controls 4-speed the AC button does light up but the compressor doesn't kick on. I meant shouldn't the AC electric fan on the rad turn on when the AC button is pressed? My other Passat does turn on the electric fan at the rad when the AC button...
  8. No Heat Low Engine Temp On Gauge

    B5 Garage
    I bought another 2003 VW Passat 1.8T I'm not feeling any heat inside the car the temp gauge was reading about 190F when I picked it up. After a few days the engine temp gauge was being funny. Temp kept dropping driving on the highway the temp was at maybe 140F but in the city temp rose too...
  9. Crummy In-town mileage w A/C on

    Volkswagen Passat B5 Discussion
    Honestly I think it's just from it being so hot this summer. 1.8T's don't like the hot summer humid air when the ECU sees the air temp above 80 F at the IAC sensor it'll try and cut boost so it doesn't detonate the fuel mixture even with the AC on you'll get poor gas mileage. When your on the...
  10. Rattling metalic noise on acceleration from engine bay; Wate

    Volkswagen Passat B5 Discussion
    I'll add on another 12 years and revive this post. lol I'm starting too hear that same noise when I'm shifting into reverse and drive. At first I thought it was the transmission or the exhaust pipe rubbing on the frame under a certain rpm. I don't know it could be the cam chain adjuster.
  11. A Turbo DOES need backpressure, after all - and some more Exhaust stuff

    Volkswagen Passat B5 Discussion
    I do see a difference when I fixed my flex pipe the turbo seems too respond better. If you eliminate the down pipe and cat and just straight pipe it this will cause your O2 sensors too read improperly and form a rich condition. Because of the free flowing exhaust the oxygen mixed with carbon...
  12. 1.8T Stumbles Once And Awhile At Idle, Misfires Under Boost

    B5 Garage
    I fixed my misfire issue and was running top notch but now it's bogging really bad after I went over a pot hole in a parking lot. When I accelerate the exhaust sounds restricted I hope I didn't kill the turbo driving on the highway commuting too work. I can hear it spool up if I hold it at...

    These 1.8T engines get extremely hot too I've been told. Yup I pulled out my dipstick and the plastic bung part crumbled and just caught a big chunk of plastic that almost fell down the dipstick tube. My new one I ordered should be here today from üro parts.

    *Update* I replaced the ignition coil last night and now no misfire and it runs like a top again!!!! :thumbup: Checked the engine oil level and the darn dipstick handle fell apart and the plastic plug also cracked and broke apart in pieces. I caught a few small chunks of plastic just in time...

    Hi I have a 2004 VW Passat 1.8T GLS with a stumble misfire when warmed up from a cold start. Under boost the engine would cut out on all cylinders when the gas pedal is pressed down at a certain point. I have a crack in the exhaust flex pipe before the catalytic converter I thought the down...

    It's still misfiring and sputtering on wide open throttle, I'll check the hoses and the vacuum suction pump, last week it ran great and felt the turbo kick in like it always did.
