1. Did oil/filter change and added ProMa MBL8 and tapping/other "shouldnt be there type" noise has gone.
2. Weird buzz still happens but im pretty sure its nothing to worry about, just a tad of a nuisance.
3. Goes and comes as it pleases. where abouts is this sensor located so i can get one from pick a part.??
4. Still havent got this looked at and if anyone could advise me on what to do it would be great.
5. Have checked bulbs and were fine, since then have re-wired and they are working fine now.
6. Turned out to be warped disc (was me guessing at something and just went with it) bought new disc from supercheap and all is well now, yayyyy now i dont have to worry on the rimutaka hill lol. This has also fixed my brake wobble.
In conclusion i still need to sort this alarm out and boot sensor. Cheers for advice so far guys.
