bluespanner Posted March 31, 2014 Share Posted March 31, 2014 Evenin' all Does anybody know if the srb500050 modulator unit on my 04 discovery is interchangeable with the earlier but more widely available srb101241? Also - are these units plug and play or do they need coding in? Many thanks Roland Quote Link to comment Share on other sites More sharing options...
Ally V8 Posted March 31, 2014 Share Posted March 31, 2014 Will be fine,why do you want to change it - if its for shuttle valve electrical failure Google around and find the repair procedure,better than fitting a replacement unit.They don't need coding.

bluespanner Posted March 31, 2014 Author Share Posted March 31, 2014 I have the three lights on, caused by the front left inlet valve shorting to supply. Quote Link to comment Share on other sites More sharing options...

bluespanner Posted April 4, 2014 Author Share Posted April 4, 2014 Well- I had my original unit tested and they say there are no faults with the modulator. Any ideas anyone? Quote Link to comment Share on other sites More sharing options...
