View Full Version : Help!! P1300 code

05-10-2008, 11:05 AM
Ok....I've got a AEB A4 and i've been dealing with missfire issues for forever now. I forgot what the codes were exactly but when i vag'ed it they were codes for missfire cylinder 1,2,3,4 and random missfire on all 4 cylinder for a total of 5 codes. So i searched this forum religously for an answer. So i changed out the MAF, ICM and plugs. I decided not to replace the coilpacks because from what i've read the icm on the aeb's goes not the coilpacks? and plus what are the chances of ALL 4 coil packs going bad simultaneously? anyways....after replacing all that it STILL idles like crap. I scanned it again and now its giving me a P1300 code. I've looked it up and i guess the code means missfire/ low fuel level. clogged fuel filter? The funny thing is it actually drives good until you come to a stop and it'll idle funny and sometimes stalls out. I've checked for vacuum leaks and boost leaks and found nothing either. has anyone else experience the codes that i got?

Try aligning the throttle body with VAG-COM.

What exactly do you have done to the car? What kind of plugs, and are they gapped right? My B5 is very tempermental with plugs and changing weather.

so i got around to messing with the car again and I found a tiny boost leak!!! around the suction jet pump part# 058133753b. When I first got the car the car was running horrible and when I popped the hood I found the suction pump had popped off into 2 pieces so the cheap ass that I am I glued it together. It worked great for about 2 years. After my boost leak test I found out that the glue over time started to crack and thus leaking. Im gonna go to the dealer tommorow and get a new one and HOPEFULLY this will cure this POS once and for all. Heres a pic of it. http://www.ecstuning.com/stage/images/dis/2420/600/2420.jpg
