As in the title has anyone had a TerraClean engine clean?
Thinking of getting my mk3 dci done but wanted some opinions first.

Not had it done personally but have a trusted, reliable mechanic friend who has had the work carried out by a licensed trader at the customers request whilst the vehicle has been on his premises for other work.

His opinion is that you should save your money.
