Stopping Volkswagen Misfire Faults

This bulletin applies to all gasoline-engine equipped 2006-2023 Volkswagen vehicles (except Routan ID). Volkswagen recommends the use of a fuel additive to prevent sporadic misfire faults P0300 (random/multiple misfires) or P0301-P0308 (cyl misfires 1-8).

A few months ago, I was working on a 2015 Jetta 2.0L (approx. 125k kms.) which had an intermittent lack of power and CEL; a scan revealed P0300. My first reaction was, intake valve deposits, because just a year prior I had already replaced the spark plugs for a slight rough idle, only when hot and in P. I ran a solvent through the intake and poured a bottle of injector cleaner in the tank. Last month, the CEL came back on with the same code, the ignition cables tested ok, so I replaced the ignition coil pack; fingers crossed. It seems P0300 is common for VW.

And why I run toptier fuel.... My VW does not like EPA gas... just one tank and rough startups and longer cranking times.
I'll still throw in the bottle of fuel system cleaner prior to every oil change and use turbo/valve cleaning sprays.
VW dealer wants $25 for this bottle.

Here is the SDS for the VW cleaner. https://www.toolsinfoweb.co.uk/cont...ervicing Material/G 001 780 M3 - ADDITIVE.PDF

I thought PEA was the only thing proven to clean injectors. Anyone know what this stuff is?

Plenty things clean injectors. Looks like this is 75-80% PEA, so plenty concentrated.... that 1st ingredient.

I thought PEA was Phenethylamine. Is that the same as ethyl homo polymer whatever?

I am not a chemist but I am trying to learn a few things at least.

They can call it, and the derivatives, lots of cool names. I prefer Nitro+ and Techron... easier to spell.

I thought it was Polyether Amine, according to Chevron.

Someone on one of the VW forums has discussed this product for misfire issues he was having that this cleared up. I run a can of LM DI Jectron each oil change.

 

[Greasymechtech]

Pretty much ANY quality fuel system cleaner can give you similar results.

I bet the VW stuff will give my Mazda, Toyota, Kias... a good cleaning too.

And, PEA is poly ether amine. Its the old chemical. Pretty sure they built on it and moved away from it.

Looks like Chevron re-formulated Techron with significantly lower PEA content.

Redline is also around 30%

If VW’s selling the German stuff here, it’s a BASF Keropur product. The US refiners, if they aren’t using their own addpack(Techron, V-Power), they’ll use a generic EPA add pack from Chevron Oronite/Afton/Lubrizol or do what Costco did and get a Top Tier-certified add pack made just for them.

IME, Chevron tends to provide the best performance. I use Safeway swill with a little Sta-Bil Marine added to it.

There are many different polyether amine compounds.
