Sajeev,

I have a 2003 Jetta TDI with 178k miles. Runs 100%. My mechanic recommends a carbon cleaning. What are the positives and negatives? To be more succinct, what can go wrong?

Hello Sajeev,

I’m a long time reader, but not much of a poster. Anyway, I currently own a 2009 SEAT Leon (bought new, I’m from Mexico if you wonder how I got this car), which is basically a 5th gen VW Golf in drag, 1.8 TSI engine and 6 speed manual, 32k km in the odometer (about 20k miles) almost 100% of city stop and go traffic. Currently, there’s nothing wrong with the car, but today I took it to the dealership for the vehicle emissions tests (all good) and looking at all the services that they provide I found this: Engine Carbon Build Up Cleaning with Hydrogen, so I ask the service representative what it was, in he basically told me that a machine is connected to the fuel system of the car and they feed it with hydrogen and keep the car running for about half an hour, and that should remove all the carbon build ups in the system.

Reading this and other forums I learned about the propensity of major carbon build in the valves, regarding the direct injected engines, so I found this interesting. Googling this cleaning system, I rapidly found about it: OxyHydrogen Engine Carbon Cleaning, although I just barely read about using it in scooter engines.

Then it came to me!! Ask Master Sajeev about it!! So I’m wondering if you ever heard of this system and if it’s really effective in removing carbon build ups, or if it is a bad idea to ever think about it. Dealership charges about $50 to perform this service by the way….

Saludos desde México!!
