New turbo now EML comes on & off

#1 by Oggi , Sun Apr 28, 2019 6:38 am

Just changed the turbo on my K74. All went great until first run out when the EML came on. The EML doesn't always come on straight away, but always within the first few minutes
Checked all the connectors vac pipes etc all appears good. Also now getting a puff of black smoke under hard acceleration.
I do have an EGR delete but the unit is still in place so plugged in, just wondering as I didn't disconnect the battery while working on the turbo change could the fact the multiplugs on the inlet manifold along with the EGR were unplugged & plugged back in have anything to do with it?

The old turbo was completely shot letting oil past & free movement in the vane shaft, could a build up of old oil it let past have anything to do with this & the new turbo working properly is pushing this through the system? Intercooler had oil trace but not running out of it.

Looking on line it may be that the turbo is not set correctly resulting in overboost, anyone got an idiots guide to checking the settings?

Nick, Thanks for that. Didn't want to go fiddling about without guidance.

Thanks again Nick.

Now sorted the EML issue, still a bit smokey under acceleration, so will continue to tweak it a bit more see if it helps.

Clean MAF, check filters (fuel and air), run a bottle of Forte through it?

Didn't think the K74 had a MAF?

Engine bay on this truck is starting to look like triggers broom. In the last 12 months: replacement engine (with belts clutch etc), starter, alternator, fuel pump, battery. in too deep £££ now otherwise would have got rid of it. Where as my Mazda B2500 which is tatty as hell has had a grand total of £50 for the MOT spent on it in the same time & done more mileage, but keeps on ticking.
