Hi guys

My friend recently gave me a couple of 500ml bottles of Wynns DC3 egr turbo and injector cleaner. I was just wondering if it's safe to use in my 2006 Fabia VRS? Lately it's got a bit sluggish and black smoke on boost I no people say the smoke if it's been mapped which mine has but I thought I'd give it a go as long as it don't cause me no problems after?

Thanks

Black smoke means engine is getting more fuel that the available air will let it burn so often due to boost problem, turbo or pipe leak but I also would have expected any kind of inlet-side blockage to lead to this - diesel inlets can get very congested. Turbo problem could include lack of movement in the variable geometry - easy enough to check from top of engine by wiggling. If this is it, could benefit from Mr Muscle though some on here are skeptical, but many others claim it worked for them. I can't see injector cleaner doing any harm - give it a go if you already have it.
