Just on my way home from work now an ive developed a serious missfire!

Probably a coilpack.

Were the coilpacks changed under the 28F5 "recall" that was issued in Feb 2011?

Good news cars booked in at vw on friday to have six new coils replaced

..i plugged it in today at work and it shower cyclinders 1.3.5 missfire

Bad news is no car till then

Odd that it's 3 that are causing problems, all from the same bank.

Oh dont say that lol I hope it's just the coils

I might be wrong here (as I have a mk5 and am far from a mechanic!) but that could well be a lambda sensor fault. As I understand it, there are four sensors, 2 in front of the Cat and 2 after it. Two are for the branch of the exhaust that goes to bank 1 (cylinders 1,3,5) and the other two are for bank 2 (cylinders 2,4,6). That might more sense that the coil packs if the fault is showing on all the odd number cylinders....

Yeah you could be right there coz it would be odd more 3 to go at the same time...do you think decat could of caused it?

Not too sure mate, possible I suppose. Mine is stock, but it seems the Lambdas may be a bit of a weak point on the R32. Had one replaced on mine recently (bank 1, front). £300 ish at VW MD all in ;(. That did include the diagnostics but I imagine a specialist could do it cheaper as the part is only about 100 to 120 I think.
