|Glow and new glory
Question : MY Land Rover TD4 runs roughly for about
20 minutes after startup in the morning. My
mechanic blames it on the fuel injection
system while the local authorized dealer
blames it on the electronic control unit
(ECU). Which ever is correct, it would be a
costly affair to put right And I hope that
your third opinion would help save me
quite a few bucks.
FROM what you have described, it seems
unlikely that either is correct, since your
engine runs sweetly after it has warmed up. It
seem very likely that one of your glow plugs
have failed and that your vehicle engine is
running on three cylinders until the engine
has reached a temperature threshold when
the remainder cylinder begins running. This is
a common occurrence in diesel engines.
Glow plugs have finite lives, usually somewhere between 50,000 and 100,000km. They
are cheap and easy to replace. Although they
can be singly replaced, I would thoroughly
recommend replacement as a set. Always use
original components where possible.
