Hi all. Sun is shining and I've got my head under this bloody car.
so it's not been started or driven for about 3 weeks , battery was dead so jump started it and it started after a struggle then it all started

temp gauge goes straight into red and fans run ( even tho it's stone cold)
hill start light is on
won't select any drive settings
eml is on
cruise light is flashing

I do live and work on a farm so I've checked for obvious signs or rat and mickey damage buy can't see any. I've tried the disconnect neg feed etc but to no avail.
car does run and drive but !!!!!

anyone at all any insight to this any help much appreciated if your not all out drunk on cider and eating bbq! !

You need to read the fault code first, anything else is guesswork.

OK il pop it up local garage and see if they can read it.

P0118 coolant error it won't reset, fault clears but immediately comes back ....short maybe? ?

Change CTS and report back

Is this a big job ? Looks like a right awkward place , guessing intercooler off , inlet manifold and some pipes ?

Don Clark

This should give you a few things to check

Thats probably your coolant temp sensor wiring gone missing and also part of your purge system pipework (items 19, 21 and 22 below)
The oil pressure switch (white plug in first pic) looks chewed as well

Don Clark

Wiring for power steering oil pressure switch.

In the first pic what's the black chewed one on the net ot looks like the cam / crank position sensor?
also any ideas of where to source the harnesses or plugs?

Don Clark

Having looked at the engine wiring loom diagram have made a few changes to post #20.

Coolant temp sensor item 18


plugs are hard to come by unless you buy a new engine loom or can find one at a breakers,

Daft question but can the be repaired and then spliced back to wires? Wires are there but they've been chewed tight against the back of the plugs ?

4evascoob

The power steering oil pressure switch ...where does this plug onto? Any diagrams of where it's routed ?

Don Clark

I think the wire you are holding goes round the back of the pump to the sensor.
You can see it in this picture

Ahh lovely that makes sense .thanks.

You can buy the plugs with what looks like a couple inches of wire ready to Re splice but how do you know what connectors / plugs are called etc?
