Guys just wondering why my D22 seems to be very sooty under the bonnet. What should I be looking at I have just over 150k on the clock it’s a 2010 Thai model
Check for loose hose clamps.
Mainly the hotside air before your intercooler. But check where the soot is, thatll be the tell-tale sign.
Even could look to give the engine bay a wipe down and keep an eye on it
