340 1.4 rough ans slow idling

[SteveP]

In my experience, the Renix unit is very reliable (only ever had one fail out of 5 300's with it fitted and that car had sat for the best part of a decade). It is often the scapegoat for other issues.

That's still a 20% failure rate which is far too high!

They are horrendously bad though, come across and heard of so many duff Renix units and not all are interchangeable, some will get you home as Clan suggests but others won't even start the car!

My friend had the crankshaft sensor fail on his 340 1.4. The car had done only about 25,000 Miles then. Mine have never failed in about 16 years of owning 340's.

mine has never failed on a 1988 ( 100,000 miles ) and a 1980 ( 250,000 miles ) which I fitted one to when the renix unit came out in about 1984 .

I remember ordering the sensor on eBay for my friend, when it arrived the cable was much longer than the original, but it worked OK. Probably about 10 years ago, car still fine.

I have been working on 300s since they came out in 1976 until they finished and beyond on a professional basis , the renix do fail on the later ones not often but I have probably changed 10 in that time . Internal fault they just stop suddenly and that's it . you stop and cant go anywhere and they are hard to find now so best look around for a spare before it goes .
