Is it the same as terraclean or along same lines then? I was disappointed with them, I had a3 2.0 tdi on 100k when done. Told him I get no smoke and no idle issues and runs well. He said its worthwhile (which I do believe it is worth while to clean built up carbon) and told me I would get improved mpg. I work in Portsmouth and live darlo, so mpg was a selling point, but peace of mind too. So got it done, no difference in mpg and he seemed surprised. I find it good to know that you state that it may not improve mpg. I say good I'm impressed, to me it's showing no bullshit. I know the problems with carbon build up on diesel engines, having had to pull on and clean tb/inlets before.

Would this clean inlet manifold/egr/turbo of carbon build up?

I'll leave Cuppa to answer that one

Sorry for the delay in replying, away at the minute.

Hi Cuppa,

You mention that the effect of carbon cleaning is down to how "dirty" the engine is and that it is down to driving style and milage etc.

Could you provide a little information as to what type of driving is likely to build up carbon in the engine to give me an idea of whether its something i would be likely to benefit from.

thanks

Sure thing Molle.

1) Low revs
2) short journeys
3) lots of stop-start journeys
4) idling

i.e. anything which means the engine doesn't get worked hard and hot. Cabs and buses/coaches are worst as they are sat idling and often short stop-start journeys at low MPH/revs in inner cities.

If you drive it with high/aggressive revs then the system gets hotter and the carbon doesn't build up as much.

Booking my car in for in about a months time once I've sorted out some other bits on it.

S5 V8 53k~ miles with an unknown engine history so no clue if it has been cleaned before. I've owned it since 43k~

Will report back after.

Will be good to get some detailed results from this one :thumbsup:

IF your car is suffering reduced MPG and IF the cause is carbon build up then yes the clean should recover/reclaim that MPG (notice the two IF words in there). Anyone GUARANTEEING improved MPG is leading you on in my opinion.

All a clean can do is exactly that. Clean.

IF (and it's always an IF) ANY aspect of your cars performance (noise, shakes, idling, hunting, MPG, emissions, flat spots, throttle response, sticking EGR/throttle body/swirl flaps) are affected from carbon build up then the clean will have an affect.

Of course if a mechanical aspect (swirl flaps for example or EGR valve) has seized completely or broken then no amount of cleaning will sort it.

Was called out for a 'dirty EGR valve' recently which actually turned out to be the EGR water cooler leaking coolant into the fuel.

The process we use will indeed get everywhere the gas can get to (turbo/inlet manifold/EGR), but it does need a flow to work...so, a clogged up DPF which has gone too far to be recovered will need replacing.

As long as you keep in mind CARBON CLEAN = RECOVER WHAT YOU HAVE LOST then you should be OK.

But there is no guarantee of improved anything as it all depends how dirty it is.

Have done 3 x B7 RS4s now and all were different to start with (some noisier than others and revving freer than others), but all got to the same end point.
Have done 2 x B8 S5s and same as above.

@Cuppa, forgive my ignorance but can you explain how this is different from a BG induction service?

My car S5 was really sluggish and I was thinking maybe I needed a carbon clean at 70k miles on the car.

Did not want to spend the money for that and find out the car was still sluggish afterwards. My indie offered a BG induction service, thought the price was reasonable
figured why not since I was getting an oil change anyway.. Well after the induction service the car felt like a new S5 I had taken for a test drive, engine felt alive and ready to race. Poured in a can of BG44k in the gas tank and now the car practically drives itself.

So any more information you can give would be helpful I do like exploring options that are less costly and don't involve opening things up.

Thanks for heading this far north Adrian. As I regularly run air system cleaner, diesel system cleaner and turbo cleaner through my A5, I suspected that the improvements following your treatment may be small. How wrong I was. It now picks up in Drive, like it used to in Sport. The usual hesitance in Drive that has been evident since I bought the car has completely disappeared. Top stuff.

Hi Gurltech, only just spotted this, sorry for the late reply.

Don't know much about the BG process and the website doesn't seem to give specifics. Looks like the BG44k is a fuel additive so will clean wherever the fuel gets to.

Not sure what they are doing at the BG Induction service so wouldn't like to comment.

Our process we feed charged Hydrogen and Oxygen gas into the air intake. Our service is fully mobile so we come to you, where as the BG service looks like you go to them.

Wherever the Hydrogen and Oxygen gas can flow to the carbon deposits will react. I spotted on another forum a comment which went along the lines on 'I've seen the lumps of carbon stuck on and there is no way a gas is going to remove that'. If you google 'oxygen carbon burn' you can see that if you get carbon hot (e.g. with engine fully warmed up) and introduce an oxygen rich environment (like we are) then the carbon just ignites, e.g.....

Thanks. Was a pleasure meeting up yesterday and glad the car feels back to its best.

Was good to do a bit of VCDS coding and get your hidden menu unlocked and your footwell lighting up and running for you too

Hi Cuppa,

Really interesting stuff. I suppose it's a bit like cleaning the engine innards with superheated steam.

Now my car has reached 80K miles I've been seriously considering something like this. One question. Does the MOT emissions test indicate whether the engine needs a clean? For the last two years mine has come back with an advisory stating that "emissions are too low to measure". I have taken this to show that all is well, certainly the car is never driven slowly!

Hi Cuppa,

Just to clarify, its the Hydrogen and Oxygen chemically reacting with the carbon, no steam involved. Steam and detergents work by 'loosening' the lumps, not chemically reacting with it and altering it.

For the last two years mine has come back with an advisory stating that "emissions are too low to measure". I have taken this to show that all is well, certainly the car is never driven slowly!

Emissions test can be a good indicator for much older cars without the cats or DPFs. If you drive it hard and rev it high then the combustion will be more complete so you'll get less carbon buildup, but with 80k on the clock I would think you'll have some buildup there, just not as much as perhaps someone who just trundles to the shops and back.

Either way if you are getting readings which are low then you know your cats/DPFs are doing their job.

Thanks Cuppa, chemistry was never my strongest subject.

Trundle, I don't even know the meaning of the word!

I think you've convinced me to get it done. :thumbsup:

Lol, in a weird freaky way I've come full circle. My first degree was Chemistry and here I am back doing something related. Coming in very handy now.

@Cuppa I got in contact today with an old friend who is in the hydro dipping and wrapping business. He then told me he is taking this same thing on for the Kent area. He is only 10mins from me at work

So I will be popping to him to have it done. For £100 its worth a shot to see

Was at Bicester Heritage Centre today where we already have approval for our process - working closely with Historit.

Feedback from the owner: 'The ride home was very interesting, definitely more power, much more responsive, but the main benefit was a smoother power band and tick over'

Inspired by reading this thread, yesterday I met up with one of Cuppa's co-franchisees, Gary, to give my (7.5 year old, 82k mile) S5 the treatment.
I'd told Gary that I wasn't expecting miracles as the car's lived on a diet of 98-99 RON supplemented by regular BG44K chasers, and experienced the perfect ritual of daily A road warm-ups followed by motorway blasts. However....
From start-up, where I noticed that the habitual V8 shake had been dampened (boo!) to stop start traffic, where the throttle response and controllability was noticeably enhanced, to the open road dashes where there was an undeniable eagerness that had me varying gears and speeds just to sample it. Wow! Money well spent indeed. And I'm convinced I've even got enhanced pops and burbles on the overrun. Bargain then!
And my scepticism banished. Try it.
