Engine management light .

[Stubby]

So this has happened 3 times in the last 8 months or so . I'm driving along and the engine management light comes on ( orange ) I think oh bollox . So I phone my local garage and book it in . This happens on the Friday and they can't look at it till Tuesday . I say ok thank you . Avoid driving it as much as possible but have to do the odd trip . This evening I went to the shooting range with light on and when I came out to drive home it went out . So no light no , point in putting a code reader on it . Bonkers innit ? I will phone them tomorrow and tell them .

If they've a decent reader, it will show then a stored code even after it's gone out.

Should have stuck to an old series 3 Land Rover, where is Kris when you need him. 😂

The joy of technology and progress.

I just could not bring myself to wear a hat like that though !

I use a Nanocom for my Disco 4, one code always appears, rear diff ecu fault. It ain't got one!

One thing I learnt today from a mate is that if it is a minor ( non life threatening code ) then it will pop up to let you know and the after a pre set number of starting cycles  it will go out again until it thinks it needs to remind you again .

There's also a degree of warning light, advisory and advisory with engine rpm limit to get you home

Is it diesel and do you do lots of short journeys?  I've had the dreaded DPF fail plus all the associated sensors.  Expensive.

Yes , been there . Had to have a few forced regens done and oil change when it diluted the engine oil with fuel . One sensor replaced ( inlet manifold boost pressure sensor ) I did do lots of short trips where in the depths of winter the temp needle would hardly come off the stop . This combination is the perfect storm for clogging the DPF . However I do less trips now but the ones I do are much longer and everything gets hot enough . Not had any DPF props since  then .
