Ripped it apart...bad rear sensor..luckily I had one..replaced it and all good..also lucky I had spare plastic push pin panel anchors as they always break..I could pull that panel now in 10 minutes...but next time I need to I'll have forgotten how again..oh well...at least I'm protected again.

Ya dinkydi I feel your pain..when our systems/components become obsolete it almost means a complete rebuild when parts no longer are available nor fit..that's progress I guess
