Member Jonathan Kay Posted May 29, 2018 Member Share Posted May 29, 2018 How many functions have you lost? There's a well-tested workaround for the starter relay.... and if i knew how to search the archives i could check......The best method of searching that I know is to use an external search engine with site restriction... click the second link in my signature and then enter the search terms etc.Jonathan Link to comment Share on other sites More sharing options...
revilla Posted May 29, 2018 Share Posted May 29, 2018 I wrote an article for Low Flying several years ago about an easy solution replacing this with a couple of relays. I can send you a copy if you want? There have been a couple of developments since then - I've found some cars are wired to use 3 of the 4 relays inside rather than 2, but that is fairly easily worked around. If it's just the MFRU itself that is damaged though, I'd go with getting a replacement on eBay. Important to note, the EU2 and EU3 MFRUs look identical but are wired differently inside; you must get the correct one. Which engine is yours? My article was only directly relevant to EU3.

Support Team Shaun_E Posted May 29, 2018 Support Team Share Posted May 29, 2018 LF Archive is online - Andrew's article is here: http://lowflying.lotus7.club/2013/2013_07_05_KClick.pdfThe search box for this site is at the top right of the screen and is working fine. Search for MFRU yields plenty of threads on the subject. Link to comment Share on other sites More sharing options...
redjohnuk Posted May 29, 2018 Author Share Posted May 29, 2018 Thank you for your input. My engine is the EU3 spec and i think, based on the above i'll pick one up from ebay.Thanks againJohn Link to comment Share on other sites More sharing options...
