Morning,

Our MH has just been into local garage for what we thought was going to be new glow plugs as EML and Glow plug warning flashed up.

MH is only 4 years old and covered 4200 miles!!!!

Garage performed a manual DPF flush and tested glow plugs, found to be ok but traced fault back to relay.

They orders in the genuine relay £200 and fitted it this morning, checked dash and EML / Glow plug warning still showing, not the relay.

The put old relay back in and said I’d need to take it to a Fiat professional dealer.

I’ve been reading this forum as a guest for sometime and there’s some knowledgeable people here, so I thought I’d ask if anyone has any idea before I pay £140+Vat for the hours diagnoses!

Thanks in advance.

Many on Forum use MES diagnostics which give good information ( I use MaxiEcu scan tool as a Scudo I had used Peugeot engine which MES doesn't read)
Given the age of your vehicle you may find a "securitygateway issue" Gendan are the suppliers of MES etc and if asked I have found very helpful.
I recently tested a 1.6 Doblo of mine using the MaxiEcu scan tool which may be a small guide if you search it on Forum.
