Bank holiday weekend and a joy of owning direct injecton engine car. 100000 miles on my vrs 

Wow those look terrible. Sure mine needs doing but I can’t face it just yet!

Now no wonder why i had a slight engine judder on idle.Injector nozles all clogged up too

When I did mine, I sent the injectors off for cleaning and testing.  They did respond to the testing.

 

Everything looked similar to yours maybe slightly less. Mine was about 70k miles when I did it.  

 

It did idle better and was more responsive after. And no more hesitation (misses) when cold under light throttle. 

It is suggested the procedure is done every 80k for keeping  optimum condition.

Fuel quality plays a role here though.

I ve bought car with 77k on clock since than premium oil premium petrol and regular servicing.Seen somewhere that cleaning should be done every 60k

yes sorry , 60k in miles seems resonable..

AFAIK the injectors should be placed in the injector cleaner for some hours, this is the best cleaning procedure .

As they are a highy cost parts , should be handled with care.

 

When i did first time in 140k (km),  idle consumption was showing  0,7 lt/h   and after cleaning all intake and parts first thing noticed dropped down to as new stable 0,5lt/h as per  computer indication .  Sometimes it goes lower to 0,4.

Never had any misfire or judders though ..

But this is very essential for all direct-injected motors to be carried over.
