  1. Volkswagen Passat B5 Discussion
    hey all: wifes 03 passat wagon (1.8T) threw a pre-cat error last week. When I looked at the group in Vagcom, it was 000000. Replaced the upstream sensor and group was back to 000111 with the third 1 switching from 0 to 1 every few seconds indicating heating on/off cycle. 5 days later, car...

    I just went to put in the 3 way PCV check valve (above the suction pump valve on AWM motor) and in testing it by blowing through it, it doesn't block airflow from any direction. The old one that came off the engine does. What's going on? Is it the wrong part (I recently found it on the board...

    Hi, My 2000, 1.8 passat's revs jump from 500 to 1500 at idle and occasionally drop for a second or two on the motorway, the airflow regulator is currently unplugged under the bonnet the reason being that the car starts but cuts out immediately if this is plugged in. what do you suggest the...

    Hello, I have seen the programs that can discect cars by different components. Does anyone here have access to the program that can show me what a 2005 Pontiac Sunfires air flow system looks like? My girlfriend has had her car for two years and it has 4 vents faceing the driver. The middle...

    Hi everyone, I have no air flow through my heat/ac vents and the AC light doen'st even come on when I push the button. I've never had any problems and one day (2 days ago) everything stopped working. Any ideas. I think it could be the blower heater, but i don't want to just go buy one and...

    whats the best way to check if the mas is bad. I was told to use a voltage meter on it but wasnt told what the proper voltage should be. I have a 2000 passat v-6 2.8 thanks for any help

    How do you know if your MAF is going bad? How do you know if your diverter valve is going bad? I've changed just about everything else but I am still having the same symptoms. The car seems to bog down a little after every shift (when is drops RPM). There is not a good power curve through the...

    Does anyone know why there are different part numbers to airflow meters fitted to same engine codes even in cars of the same year and sold in the same market?I have a 99 1.8t and have been told to check actual number on meter because there are several for that year.

    remove the wheel liner to expose the hoses/tubes to install some new clamps. Looking at the stock setup it seems there is a funnel that channels air from outside through the intercooler and then it hits the wheel liner. Seeing that autotech made some sort of vent for the 1.8T so the flow of...

    I need a MAFS to fit a 2001 B5. Motor code is AUG but I think others will fit.

    I am having a code come up on my code scanner of P0103, MAF circut high input. The car doesn't want to rev past 1800 rpm then it drops down to about 800 and bounces between 800 and 1000, no matter if the throttle is floored or pressed half way down. When this happens it smells as though it is...

    I've posted this over at b5one.com also and haven't had much of a response. I've had my b5.5 for 4 days now and we had a good dusting of snow, enough to wet the roads and have PennDOT put salt down, and I noticed that due to the aerodynamics of the car the taillights get pretty filthy as well...

    Discovered I more than likely need a mass air flow sensor for my 98 v6 30v passat. I have been having bad luck finding decent prices much less than $300 for the unit. I read some old threads about their being places you could buy them discounted for $80? Unfortunately my 98' vehicle does not...

    Hi, Could someone please post some pics showing how to get to the mafs on a 2001 passat 1.8T? I'm not having any luck looking at the old threads. To make a long story short my cel came on so I took the car to the shop. They pulled the codes and said that the front O2 sensor was bad and that the...

    Is this correct? I came across this in the discription for the O2 sensor over at ECStuning.com. link I searched and there was no mention of the O2 sensor as a possible cause. I have been getting the P0411 code for the past year or so. Have so far replaced the vacuum hoses, air pump...

    I posted the other day that my '99 wagon died. At first I thought it might have been the ICM, but my mechanic said that I have a bad mass airflow sensor and that it costs $360 for a new one. Does that price sound reasonable or does anyone know where I can get one cheaper?

    I have auto climate control. when I have the fan running with heat and then power down the fan to the off position. There is still some flow of air, air at the setting of heat or cold when I had it on last. The only way to get rid of the slight airflow is to power back on the fan , go to...

    Early December, I sent in my claim for refund on the Mass Air Flow Sensor. I had to replace mine in the fall of 1992. I have yet to receive my refund, so I called vwoa. they indicated they had received my claim, it was approved, but it may take 2-4 weeks to cut the check. I am just curious...
