Connect 1.8 TDCi 90PS 2004 plate
Started chucking our a lot of black smoke under boost acceleration so thinking that EGR might need a good clean as first remedy. I bought some aerosol EGR cleaner but I don't know precisely how to use them. The instructions are a bit vague so:
Where do I spray it (and what do I need to decouple)?
How effective is this form of cleaning?
Are there any videos that might be of assistance (although someone on here who has actually done it might be better)?
Thanks,
Greg
