Biodiesel

No need to have a key in the engine bay! You can use vagcom to tell the ecu about the keys you are going to use. However you do need the SKC (Secret Key Code) that belongs to each key, this is the number that you enter into the ecu.

And where do you plug the Vagcom in?

I don't think that Vagcom can code a Golf 1/2 key.

I thought the context was about a golf 4 TDi engine, so if you transplant this into a mk1 complete with loom you would have the diagnostic plug and electronic key. Sorry for any confusion... mk1 & 2 golfs don't have electronic keys and immobilizers (at least the ones I've owned!)

That's why they put the key elsewhere.

I decided the diesel forum was looking a bit quiet.

So i decided to post the progress of my biodiesel project.
I'm working on a baby biodiesel reactor vessel, made from a 50l beer keg. I welded up some beautiful stainless steel washing machine motor brackets for the side of it yesterday. I love tig welding!

I think my biggest problem at the moment is trying to source oil. Did anyone on biodiesel have problems with that?

They don't have waste oil, they put it in the burgers & fries

I don't wanna buy it!

I should be able to get it for free somewhere, surely. I'm going to walk the f/c shops and see who'll give me some.

Maccas oil would be a last resort- can you imagine the amount of crap that would be in that oil?

Yuck!

The vast majority of the problems caused by bd use are because people use (usually free) waste oil. This contains all sorts of nasties that must not enter your fuel system. The worst of them is good old water. If you're going to use waste oil then it has to be thoroughly cleaned before esterisation and washed afterward. When time permits and I get down to manufacturing my own it'll be made from virgin oil. I can get poppy seed oil, centrifuged and filtered, for 70c/L and canola for 80c/L. All up cost per litre shouldn't be more than 90c/L.
Also, don't forget that bd will scour out any dirt, bacterial matter and perished rubber in your fuel system. Excellent filtration is essential.
