Well I had the new type of terraclean TFSI intake cleaning process done !
Removal of either the boost pipe connector or PCV hose that connects to the intake manifold.
Then Run the treatment through, with the engine idling at approx. 1400 rpm, the smell that was coming out the exhaust was horrible, it didn’t look that dirty, but more of a Smokey type of exhaust fumes …
So let it sit for approx. 15 – 20 mins, cleared any fault codes that popped up,
Which was Random/Multiple Cylinder Misfires, on 2 of the Cylinders 3 and 4 and EVAP Emission Control Sys.
Then went on a test drive, just to make sure all was ok, all was great, run a vcds scan again, no codes! I was happy at that.
I run logs before the test, then run another set a few days later.
Now on the journey home, I seen the AVG mpg jump up to 41.7 mpg, the same journey I have struggled to see above 36mpg, and that’s trying real hard…But never mind that!
The car has come back to life, it is hard to describe how it feels now, but feels more aggressive than before, smoother, like it needed it… I have found myself to be very lucky with having this done, I’m trying to get hold of a Snap-On scope, to have a look and see if I can find anything shiny in the block, about a month ago. I seen the inside of a 2lt tfsi engine with around 40 odd k on the clock, I should have taken some photos, as the black coked up vales where scary looking, to think, sh*t like that is inside our engines… Not Good Guys!
I will most definitely be having this done at least every 6 months, unless WMI was to be fitted.
Another thing I noticed was at 70mph the cars RPM’s was just below 2400, any other time it was 2500 rpms and at 80 just under 3k any other time it sat on the 3k.
Copied from a Terraclean website:
Direct Injection Petrol Intake Valve Cleaning
Pressurised Induction Cleaning System by TerracleanDirect Injection Petrol engines all suffer from carbon build up on the back of the intake valvesAt A1 Terraclean we have a cost effective solution to this problem in the form of an annual service for prevention or an intensive treatment to break down the built up carbon on the valves and intake ports
The intense process involves injecting a unique and effective agent into the intake throttle while running the car on a slightly increased idle which softens the carbon down and releases it from the back of the valves and will be burnt of in the combustion chamber, when the treatment is complete we run the standard Terraclean system in the intake throttle to release any remaining softened carbon deposit and will also clean the throttle body and carbon deposits inside the combustion chamber
The annual service process can be done as a stand alone treatment or can be done alongside a standard Terraclean treatment for best results.
For anyone who doesnt think there car is running right or has misfires, and have run out of ideas of things to try, try this !
It worked for me !
Now my car is running the best it has for a very long time !
Also the TFSI engine with 40 odd K on the clock, had the valves all replaced now goes really well also... Is this a step before pulling the block apart to see if the valves are all gunked up...
It's been the best £80.00 i had spent in a long time. How much to replace the valves etc nevermind the labour...
Goodluck !
