I’ve been doing a bit of reading around carbon buildup around the intake/valves with FSI engines as this seems to be a problem across direct injection engines in general.
Whilst my FSI doesn’t have this problem now, I can imagine at some point it will happen due to the design of direct injection engines. My reason for reading was to see if there were any tips for helping prevent or at the very least delay the issue.
From what I’ve read it appears that part of the solution that manufacturers have found is to add a turbo as the forced induction helps keep the valves/intakes cleaner for longer. This kind of explains why most VAG cars are TFSI’s now.
My reading led me to valve cleaners/walnut blasting and ultimately removal of the intake system to clean, the last two being the more expensive options which I may have to do at some point however really want to prolong anything like this so I’d start at valve cleaners.
I'm a bit sceptical about how much carbon a valve cleaner petrol additive (specifically Liqui Moly valve cleaner) would actually remove due to the design of FSI engines however I’ve come across this YouTube clip which suggests applying differently.
My question is therefore, what are people’s thoughts on this and has anyone tried anything similar?
