Slightly off on a tangent I know but some Group 2 Homologation papers are available from BMW Mobile Tradition. They have copies of Homologation 5258 which is Group 2 2002Ti but contains a bit of the 4 valve Tii stuff as well and also Homologation 1630 which is 2002 Touring Tii. Contact Andreas Harz at
Andreas.Harz@partner.bmw.de or
info.konzernarchiv@bmw.de
If the papers you have, no matter how tatty,are Homologation 1620 which is 2002 Tii please send me a p.m.They are not available from any official source and I have been trying to obtain a copy for my Group 2 2002 Tii.
