Was in the dealers today and considered an Injector clean, they use a product called Forte been looking on the net and cam across BG 44K® which although is more expensive seems to have a good following in the US according to the blurb. Also seems that the VW audi group is using it.

Thoughts anyone???.....

What are the benefits of using this?. Is it to cure a problem or just good maintanence ?
 
VAG HQ dont actually approve of any 'flushes' being used it there vehicles because some can cause premature internal bearing wear (especially on diesels). In my opinion using fuel system cleaners shouldnt cause a problem as long as there are no specific side-effects highlighted but i'd advise using a reputable company like forte, millers, redex etc. Steer clear of cheap stuff found on ebay or in the car shop bargain-bin and spend a little bit more for peace of mind.
 
Bringing up an old thread here but I was just curious on this as I've heard on a few threads recently that these TFSI engines are quite dirty and was just wondering if it would be beneficial to run some additive through it like Redex?

As this is an older thread I'm hoping there to be some people out there with proven examples of this having made a difference or is it pointless and really a case of manually cleaning trouble areas.

Any thoughts/findings appreciated.
 
With the TFSI engine being a direct injection engine this means that filth normally washed away from the inlet and valves is allowed to manifest itself on said components until problems occur.

The dirtiness of the TFSI comes from its design and no fuel treatment will realistically cure or aid that as it won't enter the manifold.
 
I work for my local Seat dealership and we use/recommend Forte, It seem's pretty decent stuff TBH.
 
What about systems like Terraclean, would that work with TFSI engines?

When we had a demo on the system we ran it on a mk5 golf gti for a half hour and it did begin to soften the crap on the top of the valves but it would've taken a good couple of hours to remove it completely.

Apparently the system uses negatively charged particles that are not effected by air direction which allows them to travel backwards up the intake track in order to clean the manifold, egr etc - how true that is I really don't know.

I do rate terraclean I have to say. On the demo I watched the live data, misfire counters in particular and it reduced a pretty prominent, every second or so misfire into a once a minute occurrence.

Both cars felt smoother and sounded quiter as well!
 
Terra clean is completely pointless in these engines for valve cleaning as the cleaning agent gets no where near those parts. I had it done and my misfire still was there, in fact it got worse through time lol. We ended up having to strip the inlet manifold off and take out the injectors as we knew this was the cause and we found that the injector in cylinder 1 was caked in carbon deposits. After a proper clean and swap over the cars now running 100% again.

WMI is the way forward I've been to keep these engine properly clean. Hopefully bill will see this thread and explain in better detail.

Yep, spot my scepticism!

I did check the valves with a bore scope before and after, there was a definite change in the materials state but how that would end up I really couldn't say or garauntee for that matter!
 
Has anyone cleaned, or had cleaned, their intake and valves on their Cupra yet?

Mine's done just over 30k and I'm wondering at what point it will need cleaning, if at all?

It's not something I'll do myself so I'm wondering if I'd better start budgeting for it!
 
Steam clean the valves with water injection. Even if you don't want the performance increases the increased mpg is welcome and your valves will be shinny. I wouldn't use regular screen wash though as that's a gloup in itself. Stick with distilled water or water / meth if going down the performance route.
