D5 engine oxygen sensor recommendation-swirl arm link connec

[sv70]

My 2006 V70 D5 euro 4 185 bhp engine started to take a little more turning the key from cold to start up for the last couple of weeks,so i thought one or two of the glow plugs were down,after doing a resistance test as shown by cheshired5,they were all showing good.I connected an icarsoft i906 scanner and it showed -ECM-28D0-heated oxygen sensor-[HO25],which i erased and all seemed fine,but today it still took longer to start from cold-[like a glow plug problem]so i tried the fault codes again and it showed the same ECM-28DO-oxygen sensor and also 3 more codes-ECM-1870,1880 and 1890,all to do with the swirl actuator control.I erased the codes and looked at the swirl arm on shutting the engine off it moved back to the engine approx 4 times then settled,after starting it up and shutting off again it stayed put.My questions are 1-can anyone recommend a decent brand of oxygen sensor as i think it must be knackt as the code has re-appeared,and-2- is it possible the faulty oxygen sensor has caused a fault code on the swirl actuator even though it is still connected ok and is moving back and forth,any thoughts are most appreciated.

The lambda probe isn't used on initial startup,

I would be checking for air leaks in intake system before starting to replace parts,

Thanks for the info Rooster,I will do that,cheers.

Just an update,i checked for air leaks,couldn't find any,so got a new bosch sensor from euro car parts-just under £90 with the discount code,fitted it and cleared the code ran it a few days,checked for any fault codes and none present,so sensor was the culprit,strangely enough the slow cold start problem went away before the new sensor was fitted,and the swirl actuator codes must have been old codes as they haven't reappeared.For reference the bosch sensor part no is-0 258 017 454 and also-LS17454, it's 5 wire and 510mm long.
