This is the code I'm getting after I scanned it with the scan tool. <p>P0102 - Mass or Volume Air Flow Circuit Low Input.<p>It's not the AFM for sure. Because I had the AFM failure code before already and replaced the AFM. This is something else. My car runs perfect, the code only shows up after say 3000km's of driving each time I reset it. I get full boost (14-15PSI), perfect vaccum pressure (18-20) and there is no engine hesistation or irradic idle. Everything seems fine, but I need to figure out what it is. I can't just keep resetting the code everytime it shows up, it just doesn't seem right. Anyways, a friend of mine suggested that I may have a leak in the accordian style pipe going from the AFM to the Turbo. However, wouldn't this produce bad vaccum readings? I'm not positive as this pipe is located before the turbo. <p>Anyways, I'll list some of my mods just incase that may be causing the problem. I have an Auto.<p>K&N intake w/ EST heatshiled, magnecore wires, NGK iridium plugs, MSD blaster ss coil pack, EST intercooler reversal piping, EST aluminum intercooler, Turbo XS BOV (vented not recirculated), Upsolute 14PSI reflash, est 3" SS downpipe w/ race cat, EST 2.5" exhaust, etc. <p>Any help would be much appreciated. <p>Thanks,<p>Bryan

That's the reading for the MAF, I believe. However, if yoiu have a turbo, you should be getting a secondary code too (especially if there's a problem with the MAF) such as Turbo, not enough air flow, etc. A troubled MAF sensor usually also triggers a bad 02 sensor, so this one stumps me. You might want to try unplugging and plugging in the MAF sensor a few times to clean the terminals and also check for vacuum leaks and that your air filter box is clamped down tight. Could be too that your K&N needs cleaning. Do the easy and free stuff first, then post back.

The K&N filter is brand spankin new. And I've already cleaned the sensor with brake fluid (just incase some of the K&N oil clogged it up). Anyways, my AFM is brand new, I purchased it from the dealer only a few months ago. I've repeatedly only had the 1 code. It would go away for about 3000-4000km's after I've reset it then come back. Checking for leaks on the acordian style pipe is a pain. It's almost impossible to spot cracks. Anyways, looks like I have my work cut out for me tonight <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0"><p>It wouldn't have anything to do with the BOV would it? I know that on most automatic tranny cars, a vented BOV would cause the car to stall. I get back fires when my BOV vents. It should be normal since it will run rich. Not sure if that'll throw a code though. <p>Thanks for your help.<p>Bry

The MAF connector can be problematic. Unplug it and put some dielectric grease on the posts; then plug-unplug several times. That should rule out a connection issue.<p>You should return to a paper filter to rule out filter oil as well.

You have to be very careful cleaning the MAF sensor...that in itself could mess it up. I've heard not to even touch it with a Q-tip. Like kenhoeve mentioned, k&N's can be problematic for the sensor too but I still continue to use them. I follow the directions well other than oiling both sides- I only oil the underside of my filter. I think the benifits of it out weigh the risk involved- but hey, that's me.

Re: Getting a code - P0102. Need help finding the problem. (TRQSTEER)

check, clean terminals at plug in for maf...use a spray cleaner meant for cleaning contacts and apply die-electric grease after...then tie down connecter with zip tie just after terminals to reduce movement. bay13 may have pic. of this....repeat your little drive and see what happens
