Can anyone recommend reputable carbon cleaners in SE England, centring around Hertfordshire.
Thanks!
Thanks!
Think in gpf cars the second set of injectors was removed.Good, and a good idea to have a figure for doing that, though on the S4 it will cost a bit more plus a bit more.
Yes, for a short period VW Group added port injecting to some engines, but I seem to think that was eventually dropped again! Certainly my older daughter's end of May SEAT Leon Cupra does not have port injectors, just either blanking plugs or "not opened up" positions on the inlet manifold. I think the cheeky beggars said that port injection was added to the direct injection to improve emissions, no mention of it getting rid of port coking - which is obviously not a recognised issue!
