Just looked on Vivid (easier that BMW TIS) and Vivid shows 2 six wire pre-cat lambda,s and 2 four wire post cat lambda,s.
Perhaps it would have been a good idea to have got Vivid while it was on offer.
GOOD info is KING.
Kev.
ps if the O2 sensor you are scopeing is post cat then emmision,s reading are vital (as usual) as i,m sure it will fail an MOT at idle.
