    Hi Guys, Just wondering if anyone has tried this stuff and whether it works. Reason i ask is my car (2.0TFSI) has not started on 1st turn twice is a space of 2 weeks, engine just doesn't fire up. Its ok on the second attempt. I have replaced the battery a while back to varta silver, so suspect that i have carbon deposits building up. The product claims to remove carbon deposits but just what to see if anyone had similar problems and whether they tried this.

    Thanks Antmax7, i did think of that but was hoping its not that as my car has only done 21k. So i thought i'll give the bg44k a go a see if that helps as i read a guy who used it on his 2.0tfsi a4 and solved the problem after getting through a full tank. If not then i will have a look at the cam follower. I will report back, i've just ordered one worth a try.

    Then you've covered the likely problems.
    The place that the TFSi gets carbon deposits is on the intake valves as a result of the crappy PCV system,and it results in loss of peak power rather than poor starting,and it really is a significant issue on modified engines,with the valve stems collecting a lot of build-up.

    I notice i do get flats spots sometimes, but only recently so i will give it a go and see if it helps. Its due its next service next month, so if it this doesn't help i'll get Audi to look into it whilst its with them.

    A catch can like the Forge is definitely worthwhile.
    If the car isn't driven daily then that may be more likely to cause starting problems but even then,it should start easily enough.

    Have you changed your fuel filter? It's unlikely to not start due to carbon deposits??

    I would plug vcds in and seeing if you've got any errors.

    Thanks guys for replies. I was looking into catch tank, seems easy enough to fit so may do it in the future after next service.

    any fault codes? my recent hard start was down to a worn N80 valve and intermittent fuel pressure sensor fault..

    as for the bg44k... it works but the gains are short lived.. i used it after 40k miles and the engine felt super smooth, quiet etc. (seemed like it lived up to the claims on the can) but only lasted 1k miles... but i have been reading around... and its been recommended that double the dose gets a better result so im near 75k now i will try that..

    i guess nothing is better for removing carbon than a good old fashion take things apart and give it all clean.

    Whatever way you look at it,it's a good thing to do.

    The PCV is obviously a great way of keeping emissions down,but feeding oil rich rubbish back into the intake isn't a good idea,and all of the rubbish gets burnt onto the intake valves.

    Ok guys some feedback for my experience with BG44K. I put BG44k on a full tank of v-power and have done 200miles on motorway since which has bought the tank to half full. I have to say it has dramatically improved my fuel economy from 26-27mpg to 35.8mpg. I also took it for a short spin around the block yesterday and have to say it feels more responsive now. I havent had any start up issues yet, but it is too early to say as it has only ever happened twice and randomly.

    So all in all i would recommend putting BG44k in the tank if your MPG has suddenly dropped and engine does not feels as responsive as before.

    Good to hear that you have noticed a change for the better. To get the best result from it... you ideally need to keep it in the tank for 1-2 weeks and start out with a full tank as you do... not always easy if you do motorway driving... so if you can then make that half tank last as long as you can to get your money worth and for longer lasting results.

    How many people, random question, have used this BG 44K in their TFSI engines here?

    My car audi a4 B8 May 09 2.0tfsi 90K. Engine code CDNC

    Hi I am all ready more then half way trough the tank its about 2 weeks from me. Before that I did have or maybe still have the oil consumption problem so I have bought BG109 to flush the engine and BG44K after BG109 and oil change to Mobil 1 5w30 from Castrol, and with the old oil separator it was 1Lper 622miles / month.After BG109 and oil separator got done I was down with oil to about 0.48 L per 622miles. However I have now put in BG44k and hmm well where to start ... So the car fell slow after that for 2 weeks and then more responsive smooth, fun to drive but even that I have put BG44k in and MPG got even better 36.6 mpg whole average. Oil consumption well where the should a drop it was MAX so since this is a pressure sensor , Some BG44k with fuel must got in to the oil.I bought the dip stick and there is not adding up in volume only on the screen I read that 3 ring which should clean the oil when piston is moving can get stuck with carbon. I am changing oil after that tank of fuel because I have also read that somebody did't and some of his seals in engine was damage because BG44K is strong. I don't know what will be the oil consumption after all of that. but I will let You all know. I have also bought a USB borescope camera to see into some parts this video is only a first time I have used it and half the BG44K treatment so the next one should be better I want to take out the spark plugs an see inside. Can anyone tell me how the car feels after 5k since BG44K and how the parts looks like in Your opinion on there You will find Intake manifold , place for a dip stick Turbo and the flap that controls air flow
