Hi all, I did B1S1 and B1S2 sensors today. Confirm denso sensors as described earlier in this thread seem good, I could only get an equivalent blueprint b1s2 sensor, without the shroud; but hacked old shroud off and seated other side of the compression seal, works ok. Had a real issue with seized b1s2 sensor, but used ferrosol and blowtorch, plus using car weight to help turn the breaker bar and release it. Don't need to remove seats, can remove some trim and lift carpet in front (driver in UK) to access plug and the floor grommet hole etc. One note is that offset 22mm O2 sensor socket (with slot) and having medium depth is needed (not straight inline or short depth socket), the one with star aperture for breaker bar means the job is possible, it's not if one doesn't have this tool. Note that b1s1 sensor is much easier, but quite tight access, the dox-0263 works nicely.
Anyway, takes around 4hrs for both, incl overcoming seized sensor, few cups of tea and some cigs.
Now just to get micro fuses to replace the 7.5amp obd fuse that I blew resetting the codes. Who knows how.
Cheers
