Putting this in the performance section because it could be directly related to my injectors (Firad +80s) or it might not.
Basically I am noticing more and more now my car is emitting a grey smoke just pulling away / using light power in 1st and 2nd gear. It might do in third too but at speed it's not as clear to see in the wingmirror (side exit exhaust).
Since my track session a couple of months ago, and my 2 track sessions on Saturday, it seems to be getting ever so slightly worse. I have a full trackday booked and paid for on 8th October so would like to maybe get this at least diagnosed even if I don't get it fixed in time.
On track, weirdly, the car has been noted as being quite clean (for a car approaching 300bhp without NOS) with not much smoke on full chat, full boost, etc. It's just this slightly (anti social too) annoying grey smoke on normal driving. Also, I have watched the smoke as I go from "normal" to "brisk" acceleration and it just changes colour from light grey to dark grey.
First thought is a potentially broken nozzle which might mean it is pushing in a bit too much fuel on just light driving. It cannot be too excessive anyway as I am not getting any worse fuel economy than normal at the moment. I have full VCDS so could log fuelling, if VCDS could pick up a dodgy nozzle. I have no way to diagnose anything though so would need pointing to the right group to log.
I am also getting minimal oil usage, so I am assuming the smoke isn't oil related (suggesting serious bottom end issues)
Here's me just on light load in a corner on Saturday
and this is full load, main straight
