Default AU: liqui-moly purge

G'day
Has anyone used liqui-moly diesel purge on their 3.0TDI 2011 if so where did they hook it up . I used it on my 2006 nissan pathfinder and it was great and now I have 210,000 kilometers on the clock I think it might be time

Read the product directions. On my '10 w/the large fuel filter housing, I simply removed the housing cover (there is a pressure release on the cover), discarded dirty old fuel filter, cleaned any deposits/detritus from interior well, shook can and poured some into the filter well, installed new filter, poured more of purge product into filter/well until about full (this is important as the replacement filter has to be forced down into the well, and cover gasket fits inside well), as you don't want this product splashing all over you or getting wasted. After carefully not overfilling the filter housing, reinstalled fuel filter housing cover and secured evenly, secured the pressure release screw/bolt, etc., and poured the rest in can into fuel tank like it says to do. If you haven't done this prior, it's good idea to take pictures as you disassemble to ensure you get it back together correctly with gaskets in proper places, etc.

It does say you can pull off a hose and siphon straight from the can, if your are needing maximum concentrated cleaning to injectors, etc., but also recommends the replace fuel filter and 'do this', to get max results. Again, read the can. Newer model TDI cars just have a tubular aluminum fuel filter (no large filter well with multiple hoses attached to it's cover) that gets replaced, so be sure you understand the specs on your year car.

Did want to recommend you use the LM proline TDI oil flush product as well, at next interval, or if level-setting on you TDI currently. That in conjunction with the LM motor oil (4200) for the TDI really makes a difference on this engine.

Testimonial: Real Life Example of Why You Should Use Liqui Moly Oil

Sister has a Kia Sorento with heavy oil consumption problems (known issue with Kia's Theta series GDI engines). Heard it start and immediately knew it was low on oil; it took two liters of my TDI's Liqui Moly 5w30 to bring it up to max-fill line. Thought nothing of donating it, as just trying to keep her car from imploding on her, and that's what I had on hand, so in it went before she ran her next errand. Merely a stop-gap action on my part. They reported the car now is only using about 1/4 quart per 1000 miles; a massive reduction in oil usage. Now, perhaps that's as good as it will get, but just think if they'd left the 2 liters of Liqui Moly oil in their car for longer than a week. They changed the oil prior to driving it back home 5 hrs. Pity, as the Liqui Moly oil is very good at what it does.

put the purge in the fuel tank when it was almost empty but before the reserve light came on and drove a couple of hundred Kilometer before the purge it had a slight miss and was using more fuel now back to smooth running and less fuel used

That's excellent! When we got our TDIs used, we did a 'level reset' on the maintenance, changed all the filters and lubricants on car and ran all the Liqui Moly purge products through them to get out the old gunk clogging up the internals (proline oil flush, proline fuel purge, etc.). Eventually we got around to using the Liqui Moly oil in them also and now they are both so quiet and smooth running compared to when we first got them. Wish I would have tried their oil sooner, but now i won't use any other besides the Liqui Moly.

Products that actually work beyond expectation and reasonably priced at that; such a novel concept.

Interesting. I just started using LM 4200 on my 2014. Get it from fcpeuro so I only pay shipping each oil change.

My first time using anything other than the Audi brand.
