allan 295 Report post Posted July 25, 2010 Noticed some water on the garage floor and tracked it down to the temperature sender unit. Upon removing it I found it has only got one small "O" ring to seal it off. Does anyone know can the O ring be replaced seperately or is it a whole new sender unit No 4?. http://www.realoem.com/bmw/showparts.do?mo...hg=11&fg=35 Thanks for any help Quote Share this post Link to post Share on other sites
hotwire 352 Report post Posted July 25, 2010 Allan, Haven't done one but picture shows no breakdown of sensor/ seal so from that - obviously not available from stealers. If the seal comes off - can it matched with a generic one - eg - is it a typical round section O ring? If so - you should be able to get another from Engineers Supplies or similar Quote Share this post Link to post Share on other sites
