I have read that Audi and VW petrol motors with direct fuel injection have had problems with carbon build up on the inlet valves over a period of time

which has to be mechanically removed  to avoid engine problems.  This procedure is very time consuming and expensive. 

 

My 2016 Skoda Scout with the 1.8 liter TSI motor is the first Skoda I have owned with direct fuel injection.

 

 I also own a Skoda Roomster with the 1.6 liter 16V petrol motor with port fuel injection and that vehicle has traveled  over 190,000 kilometers

with the only maintenance being new spark plugs, oil changes and filters.  

 

Can anyone advise whether I am likely to encounter carbon build up around the inlet valves of the motor and if so approximately what distance 

was traveled before this became a problem.

EA-888 GEN3 engines (1.8-2.0 TSI) have dual port injection (both port and direct), therefore there is no danger of having carbon deposits build up on the inlet valves. 

These engines (should) have both FSI injectors, (high pressure, into the combustion chamber) and MPI injectors (low pressure, into the manifold) The original move to only FSI left the valves prone to carbon build up on the intake valves as there was no fuel washing them on the way in.

 

Apart from North America the EA888 gen 3 engines were also fitted with 4x MPI injectors for low and full power operation. The advantage of which is it now puts fuel over the valves.

 

I am not completely sure of the spec down under but I don't think it was a US VW spec engine and 2016 will be before the current move to not fit MPI in some engines. You can see the MPI fuel rail if it is there on the intake manifold

 

Have a look in THIS thread for photographs

Is this the same engine as in a 2010 scirocco?  A friend had a new inlet installed recently due to something related. Common apparently.  In the US the part is covered for 100k miles.

No it wouldn't involve the inlet, it would be the inlet VALVES. They don't need replacing just cleaning, usually by blasting with crushed wallnut shells.

Thanks to everyone who responded to my post.  I am very happy to be advised my car has port injection as well as direct injection and as a consequence

I  have a vehicle which will give me trouble free service.
