Re: Odd problem with Renault Megane
Seems doubtful that the
would cause the temperature reading fluctuations.
I'd be looking at the CTS (temp. sensor) to injection
connection, the terminals, connector(s) and wire.
Perhaps you would be better with an auto electrician than a garage. Not familiar with 1.6 myself but it would be relevant whether there is a separate CTS for the temperature gauge.
I fear this might be the start of a series of notion/replacement of parts syndrome that I so often read on these threads because of a failure to diagnose the problem.
