[Closed] New reverb 2016 b1 same issues

Hey guys

Had my last 150mm stealth reverb 18months then it developed the dreaded drop 10 to 20mm and play front and rear....

Sent off to rs uk 10 days later they sent me a new and improved 2016 b1 which I was over the moon with....

4 rides later less than 120miles and it's started to drop 10mm while in any position other than lowest obviously... tried bleeding it there was a little air in there but it's made no difference still dropping 10mm

Anyone else had this with the new and improved (my arse) 2016 b1

Anyone any ideas before I send it back....
