Where the hell is my glow plug relay! 1.4 BNV pd engine

[locoboy]

I've been having what I think is a temperature relayed starting issue. 

The car has always cracked into life pretty easily then a couple of months ago she turned over a little longer than normal so much so that I'd let the key go because it's normally away by then. I tried again and up she went.

Another time same thing but when I re tried she struggled then seemed to crank/run on one/two cylinder then chugged her way into life.

No issues for a while then I had a real chuggy episode so I tested and found 2 of the 3 glow plugs were dead. Replaced them last week and had one sluggish start this morning at 3 degrees c.

This afternoon I tested the power to the glow plugs and I can't get a reading with the meter connected from with negative lead to negative battery post, positive to the connector that plugs onto the glow plug, ignition flicked to on and meter goes from 0.00v to 0.01v then back to 0.00v

Where the hell is the relay!!? Or the fuse for that matter, the fuse board under the steering wheel doesn't have the coil symbol on the guide.

Checked all fused on top of the battery and all good.

Hope you can help

To test the glowplugs you need to set your meter to Ohms and measure the resistance across the plug with its lead disconnected.

It should read a few ohms and not be open circuit.

 

You should replace the CTS if it hasn't already been done.

I'm not testing the glow plugs, I was testing the supply TO the plugs. 

I'd already tested the actual plugs and replaced the faulty ones. 

What's a CTS please?

Fuse is one of the strip fuses above battery, 50A rated with a thick red/black wire coming from it. Right-most one as you look from standing in front of car.

Relay is in position 9 of the relay panel behind dash.

Thanks, the fuse is good then.

You say behind the dash.... any pointers on getting eyes on them?  Drivers side? Passengers side? 

Thanks

Not personally looked, but driver's side right of steering wheel, I think. Not sure what trim may need removing to access. Other mk2 owners or maybe YouTube should be able to help.

Coolant temperature sensor. It's how the ECU knows whether the engine is cold or not.

Does it control the temp gauge on the dash too? If it dies then it seems to be working as its always done.

Yes, except the software driving the needle motor makes it indicate 90 for a fairly wide range of real temps.
