Hi, I got a bad misfire and a flashing check engine light. Codes are P0300, P0303 and P0304 pd. Which means general misfires and misfires detected on cylinders 3 & 4. Anyone know what would cause this? Coil?

Thanks in advance for all the good advice you all always offer!

swap coilpacks 3&4 with 1&2 and if the misfires continues in 3&4, its the plugs, if it moves with the packs, its the packs.

They go 1-2-3-4 from passenger-> drivers side

 

Wow, that was fast. Thanks! I'll check it out tonight. Never have touched the coil packs. Easy to get to?

Thanks!

Just pull the cover off with a flathead or keys and then if you have the push downs, you just pull the tab and swap them. If you have the bolt downs, you will need a 5mm allen to get them off.

 

Great! Thank you I really appreciate it.

 

Just Vag-com scanned my 3.0L B6 tonight.

I got two codes.


P0300 -Random/Mutiple Cylinder Misfire Detected

P0305 -Cylinder 5 misfire






I just replaced spark plugs 2 weeks ago.

What causes this problem? Coil pack?

 

sounds like the coil packs, if so you should replace them all because they prob aren't the most recent part numbers

common failure

 

I just had this problem with my TT. I replaced the coils with STI ones, and I still had the problem so I had to get some new stock ones.

 

I just hope people check plugs/gaps and swap packs around before dropping a $30+/pack that may not be the cause.

 

Well, I swapped the coil packs and I'm still getting the same codes.
