Hi Guys I've had my 1.4 206 hdi into the dealers today to give me a price for replacing the diesel additive as the warning light occasionally flashes, especially after start up. After an hour they came back to me saying that the battery needs replacing which is causing the problem as it is returning a low voltage, sounds feasible I suppose but they also told me my car doesn't have the diesel additive system. I'm totally confused by that, I was under the impression all hdi' were fitted with this system ?
