    04'Passat GLS 1.8T auto. Son recently came out to a dead battery. when boosted we discovered that the right side signals were on steady, thus explains dead battery. Moved signal switch to activate left side and all works as it should, yet right side remains on, no flash, just steady. Assume...

    Hello community, I posted here http://www.passatworld.com/forums/70-noob-tube/355537-greetings-passatworld-2003-passat-2-8-30v-4motion.html#post2946770, of my girlfriends new car. While acquiring this car I noticed a slight rough idle and rpm fluctuations. After looking further into it, the...

    I've read through the forums and used the search tools for topics similar to mine. I'd appreciate it if y'all could vett my troubleshooting and also help me with a few questions. History: I have a 2004 B5 1.8T AWM automatic w/ 85,000 miles. The CEL had been on for about a week (I don't drive it...

    So I have just had the TB and WP replaced along with the thermostat. Today I was on my longest drive since this was done and had the A/C going. After about 30 min. of driving I noticed that the A/C wasn't cooling as much and I noticed that the Water temp had moved from the usual 190 mark and...

    So I have this weird surge that has suddenly appeared very recently. It appears when I'm under steady part-throttle and while driving up a slight grade (enough that the engine is under a slight load). I'd guess the frequency is about a surge per second or so. I can both see it on the tach and...

    Ok....did the diagnosis. Found it was #3, changed plug..no change..checked old plug and it fires.....swapped #2 coil for #3, stayed with #3. Is this the ICU or could it be a injector? I replaced the ICU about 4 1/2 years ago at 60K, now have 135K. Can't find people here with any injector...

    I got my 99 1.8T Passat this year just about a month ago. The previous owner was very creative it seems and painted the entire lower section silver. They also carried their silver theme into the engine bay and the antennae, anything that's plastic and paintable :crazy: So I've been working at...

    Recently I've noticed when crusising at a steady state that my coolant temperature will come off of the middle point (190deg?). In addition my avg MPG has dropped from 27.8 to 22.3. No CELs. The engne should be in good tune. I've just had the MAF replaced, new factory plugs, new vacuum lines...

    Steady from time to time kicks(about 5 sec) in P or N position Tiptronic(2.0 FSI) when idling RPM. Anybody know what is it?

    Is it normal that it's almost impossible to keep the engine on 2500 rpm? I tried to follow an instruction for checking the MAF, the idea was to keep the engine at 2500 rpm and the MAF would need to be inbetween 7.5-12 g/s. But even how slowly I try to rev it up to 2500 the engine starts revving...

    All, My 2002 4mo has had an on/off steady check engine light for the last month or so. The car is running absolutely normally - but the light will come on and stay on for a few days, go off for a day or so, and then back for another 4-5 days. I called the dealer, he said it's probably...

    Fired it up this morning and was a little rough at first but stabilized within 3 seconds then the CEL came on! :mad: Let it idle for a couple of minutes then I shut her down to check evrything on the engine bay - nothing obvious. Started it back but now the CEL is on so I took it for a spin...
  15. Volkswagen Passat B5 Discussion
    did a quick, but fruitless search, so here goes: today about halfway thru doing my errands, my CEL comes on steadily, but the car seems to be behaving completely normally. Idle is smooth, power delivery seems right, no other idiot lights or indicators indicating anything. the car is a '99...
