Very informative video! I really like that you presented another option that is very easy to perform, takes a limited amount of time, and it is absolutely free! The added bonus of doing this coil swap experiment will help to, not only isolate the problem, but it also will reinforce what the code scanning tool’s determination is stating to be the root cause of the malfunction. I’ve watched a few videos about this issue and you are the first one to provide a second option to try that will prove the scan results as valid. Great tip! I have come to the conclusion that this fault code is caused by several things, and it can be from one item or from a combination many items. These items are spark plugs, coil pack(s) and/or coil pack electrical plug in connector(s), oil separator, (similar to a PCV valve/crank case valve), rear main seal ( where the air is drawn through by the oil separator), and faulty valves,( which are a specific and unique type that costs around $50 U.S. per valve and there are 8 valves in all.(price is not exact at time of post) The valve guides appear to be made of a unique material as well, and were not available to be purchased individually from VW Germany.[Note: This info regarding valve guide availability was per a popular YT auto repair channel episode which was over a year old at the time of this post. I have no further info on possible current availability] Substituting brass in its place only fixed the problem temporarily due to the rapid deterioration of the soft material often lasting less than 6 months. The best, and the cheapest option, is to just buy a new head in general, instead of having the current one rebuilt.

The MB II tool, online says it’s for Mercedes. Did you have to do something specific to get it to work with VW?

Im having the same exact issue on my 2012 tiguan. literally came on over the weekend loid clicking assing oil no go i bought spark plugs only should i get coils as well ?

Can you link where you got the parts and tools? I will be doing this myself

I have a P0304 code misfire cylinder 4, i changed out all spark plugs and coils, cleared code and 4 days later code is back. Any suggestions?

Coil #4 was the bad one. Should of switched 4 for number 1 to confirm 4 was the bad coil. Save diagnose time & accurate problem solution. Very rare spark plugs will cause check engine light due to

Hi!!!

what if your spark plugs sound like they are sparking for to long after u replace them

When I erase the code and didn't get new code immediate like you. I use torque pro to clear the code. I have to drive several days to get the engine light comes again then to read the code. Is that because I don't have the scan tool like you?

What's the torque spec for the spark plugs?

NO NEED FOR ANTISEIZE ON THE SPARK PLUG TREADS?

Damn nice manly voice

That’s what I did, and I replaced the 4 coils…after driving it for a few miles, the same thing came back.

thanks for showing us sparkplugs, we've never seen them before. ffs
