Hey everyone,

I'm currently watching a Golf Mk4 1.4 16V on ebay. Could be a potential bargain, depending on the problem it has.

The seller has described it, saying smoke from exhaust is sometimes black, other times white, and sometimes doesn't smoke at all. Mechanic has apparently said its an electrical fault concerning the fuel mixture.

Anyone have any ideas what the problem could be and how much it's likely to cost to fix if confirmed by a diagnostic?

Cheers

Finn
