03 LT35 Glow Plug Problem

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi, I'm new to this forum so forgive me if this is posted in the wrong place.

My 2.5 LT35 (03) seems to have lost voltage at the heater plugs.  I have removed the relay(2D0 911 253) and with the cover removed and just the low current plug (ECU side) connected the relay is not moving.

As there is a small circuit board on the coil side of the relay I'm a little hesitant to plonk 12v onto it.  The coil itself has a resistance of 670 ohms.

The low current (coil side of the relay) plug uses pins 
T
31
15
Is it possible to put 12v onto any of these pins to check the relay?

It would seem that the ECU supplies the coil voltage after some temperature checks.  What else should I be checking before deciding that the relay is at fault.

The heater light on the dashboard comes on and goes off as normal.

Many thanks for any pointers
