Thanks for the reply, Do I just check the cable for wear ant tear of is there a way to check using a multi meter? Thanks Paul

Still trying to resolve this issue unfortunately. The car is a Type 1U Octavia. I have replaced glow plug relay, glow plugs and coolant temp sensor. Glow plug light just stays on for about 1 second even though temperature is below freezing. I am getting the following error from the computer Address 01: Engine Controller: 038 906 012 HA Component: 1,9l R4 EDC 0000SG 4922 Coding: 00002 Shop # WSC 31480 17664 - Engine Coolant Temp Sensor (G62): Open or Short to Plus P1256 - 35-00--

Looks the same as the one I took out. Got it from main dealer who located it using the chasis number.

Still having problems unfortunately. So far I have replaced the glow plugs, glow plug relay and coolant temperature sensor. The glow plug light still goes out almost immediately when i turn the key. Lots of difficulty starting in the mornings, have to turn key 5 or 6 times to get some heat into plugs. I did notice that if I remove the cable from the CTS the glow plug light stays on for 10 second or so and car starts fine. Anyone got any ideas? Thanks to everyone for the help so far. Paul.

Sounds difficult to a access. Should I be able to get at this from the engine compartment or should I go at it from underneath.

It was below 5C this morning and the glow plug light still went out after 2 secs. If I disconnect the coolant sensor it goes out after 2 secs also.

Still having difficulty with this issue. I have tried the following; 1. Replaced glow plugs 2. Replaced relay 103 and 109 3. Removed cable from cooland tank The problem still exists. When I turn the key the glow plug light comes on and goes off after about 2 seconds. It is not heating long enough so starting the car is difficult. Thanks for the help so far. Any more suggestions would be welcomed. Regards Paul.

I am trying to find where the glow plug relay is on a 2003/2004 skoda octavia - any ideas? My problem is that the glow plug light comes on but goes off after a second even when the engine is cold. I have replaced the glow plugs and would like to try replacing the relay also. Thanks Paul.
