Master DF025 & DF537 Codes

Post by Johnnywizz »

Hello. New to the forum, hoping someone can offer some advice.

I have a master with 2 issues DF025 & DF537, via MUCAR reader.

Its a Master 2008 120 dci. Van runs fine.

Glow Plug light and Serv stay lit constantly (goes on stays on) even when running.

The glow plugs do not glow when plugged in but removed and earthed when ignition is on, but getting power to the glow plug lead.
Should the glow plug switch on whenever the ignition is on or is there a temperature sensor somewhere? I have also changed the glow plugs for new ones and the relay for a spare.

Any help appreciated.
