Cataclean

Ages ago.. on my dads Passat,

Not sure if it did anything though

His MAF was faulty :p

I remember seeing it sold on some TV Channel and a laboratory and swedish car authority had said it was good stuff, probably all lies :(
 
The only reason I say this is because I have a slightly missfire on cyl 1 (only noticed as I was doing some logging) you can't feel it. Got it down to a dodgy coil pack but not sure how long it's been like that.

Ordered 4 new ones the other day!

I know missfires can cause problems with blocking the cat.
 
is it?

i thought as long as u can pass the mot it's all good

edit: just read that the manufactures have to supply the vehicle with one, but it can be taken off legally after the car is sold
