2016 B Class Glow plugs Info needed

[Kerabo]

<div class="bbWrapper">My daughters 2026 B Class had the engine warning light come on.<br /> I put my iCar soft tester on it and it found unknown code PO38096. I looked this up and it said glow plugs.<br /> I eventually got the cover off the engine fuse box and can see a line of very strong fuses. 100 amp plus.<br /> I have very little info on this car so are there any common Faults?<br /> I can’t even see the glow plugs.<br /> Can anyone tell me which fuse and relay it is please Or a pic of the wiring diagram? <br /> Thanks Ken</div>

<div class="bbWrapper">Most often one or more glow plugs gone and at least on other Mercedes models the glow plug control unit too.</div>

Can’t even see them so maybe not a good job. Been told it could be a Renault engine ?<br /> are they 3 cyl as it’s very narrow ?<br /> She just started up and the light came on.<br /> phone me at 5 in the morning and said oil light was on. <br /> by the time we realised she missed her flight.</div>

<div class="bbWrapper">No, they are 4 cylinder engines. If I remember right, the smaller engines are Renault, on the facelift also 180 CDI.</div>
