Thank you for your answer. So far it still seems to work. However, even for lower ranks I receive some kind of recursion mistake again for certain loop-integrals one example is:

(p2^Lor1 p2^Lor2 p1^4 ((p1 q))^2)/(p2^2--mG^2).(p1^2--mG^2)^6 =

-((-4 + D)*(-2 + D)*(2 + D)*(4 + D)*TAI[D, 0, {{1, I*mG}}]*
    (D*FVD[q, Lor1]*FVD[q, Lor2]*TAI[D, 0,
       {{1, FeynCalc`ToTFI`Private`mM}}] + MTD[Lor1, Lor2]*SPD[q, q]*
      ((-1 + D)*mG^2*TAI[D, 0, {{1, I*mG}}] -
       D*TAI[D, 0, {{1, FeynCalc`ToTFI`Private`mM}}])))/
  (3840*(-1 + D)*D*mG^4)

I assume I can replace the internal variable by mG but this seems to me like a bug somewhere.

Cheers,
Philipp
