can any one tell me please will TerraClean de-coke the turbo?

TerraClean tell me it will but from what I can see they only use the fuel system so not sure how it can clean the turbo?

has anyone on here tried TerraClean on the TDI and how did you find it??
 
I use Revive cleaner on TDi's
removes a lot of clag out of the whole system inc vnt's

been successfull 90% of the time so far on TDi's with over boost limp mode from sticky vnts

I have a terraclean demo this thursday on a couple of cars so will know more about their product after
 
thanks mate could you let me know what you think of terraclean after you had your demo please.
my problem is I've been playing round with cars/engines for years but this is my 1st TDI turbo so never done it before and don't know anyone local who has or I would take it off myself and clean it out but saying that if terraclean does what it says on the tin it would be worth getting the whole system cleaned out, seen a lot of good reviews on this terraclean though but its not cheap for someone on a limited budget so don't want to pay out some £110 if it don't work

Please do let us know, been looking at Terraclean for a while now!
 
Been told by TerraClean on facebook...... Terraclean wrote: "Hi, exhaust gases travel through the turbo. TerraClean cleans in both liquid and gas form, hence it reaches so many places. Have a chat with your local operator."

be really interesting to get an honest review from ibizacupra to see what he thinks when he gets his demo, if it were cheaper I'd have it done for the hell of it but at £110 where I live its a lot of money for people like myself who's on a limited budget
 
might be getting mine done over weekend if I know its going to be worth the high amount of cash :)

"Hi, exhaust gases travel through the turbo. TerraClean cleans in both liquid and gas form, hence it reaches so many places. Have a chat with your local operator."

the system demo'd was a fuel line/system cleaner not an intake cleaner...
there is in my mind a significant difference.

The demo I had went ok, one TFSi leon cupra and a TDi Arosa (both my cars)

TDi one, 110k miles on its little 1400TDi 3 cyl engine.
My cupra, 14k miles petrol FSi

The system connects to the fuel system under the engine bay "only".. so the cars respectively run on terraclean "fuel" not the cars fuel.

Direct injected engines dont spray fuel down the intakes to make this clear.. Be they TDi or TFSi. Claims for decarbonising the "intake" seem incredulous given none of the "cleaning fuel product" passes by the intake system at all. It does pass thru the rail and injectors, into the combustion chamber and exit out of the exhaust ports to turbo, downpipe etc... Its cleaning of these elements where coked and carboned up I can see as being possible. The cleaning claims of cleaning the intake system I do not.

There may well be other types of fuel system cleaner process than terraclean, but anything which is being added into the fuel only will be limited to the fuel system and combustion process. I do not see how it can clean an intake. From my obeservations of the TFSi leon which I did an inspection of afterwards, it looked the same coked condition.

I also did a dyno on the leon post treatment and although I saw a higher bhp figure, it was in the realms of measurement scatter and difference in temperatures the dyno's were done on. 345bhp-350bhp kind of comparison, but a 3-5bhp variance in runs depending how hot the motor was... so inconclusive.. No losses tho - lol


I think the terraclean has merit for fuel system decarbonising, but the additional claims of EGR cleaning, intake cleaning via this process I question... The fumes from byproduct of combustion being adequate to clean and strip carbon build up from the breather system alone??? Nah... I just dont see it or believe it.

As to whether you believe its for you or not or value etc..... The "payback" of having a clean on your motor is one of economy and smoothness.. Economy has a payback, smoothness is a nice to have. We are still running the cars around so economy I cant comment on as yet, but the claims are that improvements will be seen. I hope that to be true and look fwd to seeing these in due course.

thanks for the honest review ibizacupra, what would you charge for a de-coke of the egr turbo etc? I live in devon but really wanted to know how much it should cost at my local garage should I ask them to do it, tho might have a go at it myself
 
Just had my FR Tdi terracleaned this morning, car is suffering from the dreaded limp mode overboost but high up the rev range (4000) and only in the upper gears. First impression is that the car is quieter, smoother and more responsive to drive. Time will tell if it has cured the overboost problem.
Cost £108
Car has done 94000 miles and does a lot of short journeys of less than 6 miles.
I'll report back in a couple of days .
 
Well.. a week or so later..
Leon TFSi no different.. in any respect I can find.

Aroso TDi, smoother, yes, mpg unchanged which is a little dissapointing as that was one of the expectations I was told it would do. Not yet. Will see how this next tank goes
 
Our 1.6 diesel has been done and seems less smokey.
Otherwise, not noticed any change in engine response.
Before TerraClean (c6 months to end July)= 5,978 miles = 56.4 mpg at an average 29 mpg.
After TerraClean (end July - now, 4/1/14 ) = 5,964 miles = 56.4 mpg at an average 30 mpg.
Both similar mixture of city and motorway driving and warm/cold/wet months.
So, as far as I am concerned, there is no noticeable difference in mpg
 
Just getting my car terracleaned. Only time will tell how well it works. Not expecting a big difference as I only have 35k, however mpg is low so thought it was worth a go. It certainly won't hurt.
 
Well terraclean done, not really been able to do proper test drive as had to go back and pick up the mrs' car which is getting done any min. My findings so far:
As soon as it started up I could hear the engine sounded quieter. Felt alot more free revving. On pulling away it revved quicker more responsive, a bit nippier. Coming on and off throttle is alot smoother too. Only done about 2 miles so obviously dont know about mpg yet but will update when the tank is empty.
Heres a pic of the pipework hooked
up

Just did a couple of miles round town and even my girlfriend was shocked by how much of a difference there is, turbo spools quicker and kicks in alot harder
 
Today I refuelled for the first time, previously i only got 420 miles til the fuel light came on. Got 462 this time so 10% increase in miles per tank.
Mpg figures have increased from 36 to 41. Figures calculated not taken from trip meter.
 
I would go for it, even if you don't get any real gains, you will have peace of mind that your car is as close to original condition as it can be, and you won't be too much out of pocket
 
@ Bill if you're still subscribed to this thread. I noticed in your post that you thought there might be some merit to the decarbonising properties of the terraclean process. With your experience of tuning and knowledge of detonation/knock conditions and the attributing effects that carbonised deposits can present to the phenomenon do you think that the decarbonisation in a 100,000 mile 1.8t engine would be advantageous in tuning potential and I suppose what I'm trying to ask is more importantly how much would it benefit. I'm not that experienced with knock. I think I heard it once in a very unhappy 1.6 ford sierra in second gear at 70mph probably hitting about 7000 rpm, no rev counter. Anyway, thanks if you read this, thanks even more if you answer cause I realise you're a busy fella. Sam.
