so love my Audi's currently have 2 A4's both Sline 1 off 220bhp quattro Avant and 1 off 140bhp tdi saloon both great cars but just lately the tdi has started to chug under light acceleration. if I boot it, it's fine and pulls really well, black smoke as expected but this does clear after a couple of goes. My thinking is that there is carbon build up on the injectors I've run a fuel additive but so far only in 1 tank of fuel.

my question is before I start looking at stripping down and removing and cleaning the injectors would a carbon clean/terraclean help this? has anyone used one of these and if so was it worth it?

 

cheers for looking I'm sure this question will have been asked before?

Hi Dave,

I am having a carbon clean later this morning funnily enough so will let you know how it goes.
