    its not a direct injection car, so will be little to no benefit.

    I took the head of mine to change it at about 130k, it was nice a clean apart from a little white carbon on the exhaust valves, and noting short of a chisel or wire wheel will touch that.

    RS4 B7's suffer badly from carbon build up due to FSI but not E36 M3's.

    Not an M3 :(
    Echoing Iain - no port injection motor should require carbon cleaning. Direct injection however - it's pretty much part of basic maintenance - it absolutely will have to be done at some point.

    As other’s have said carbon cleaning is only worth it on direct injection cars (which is mainly 2007 upwards).

    The best way for you to de-gunk the carbon deposits on your intake and exhaust valves is to fill up your tank with V power and take it for an Italian tune up.

    I did a Carbon clean on my E92 M3, more as maintenance however saw about 8hp increase on the dyno and a couple of mpg benefits with more smoother power delivery...

    Not something i will do every year but imho think its is something to do after 20k miles or so..
