Need some help???

So last year when driving motorhome home from storage check engine light came on. Dealer replace DEF Wenesday and yup you guessed it check engine light came on. Dealer had to replace the connector and pump again. But it was still in warrenty till the end of May so no problem on the bill. My question is has anybody else experienced this? I use the good DEF fluid and their suggestion to come back in the fall and they will show me how to remove the def pump doesn't sound right.

Please give the collective more information. Year make and model of unit in question. Your reference to DEF makes me believe it is a diesel which might be a Seneca, but beyond that.....I can't make out anything else. Thank you.

Did they replace the DEF when they put in the pump? If not, there is the possibility that the DEF is contaminated and that will set off the computer in some vehicles.

Right after that I took unit to middlebury for its last warranty done so used three fresh jugs before parking it . They say leaving it parked allows the def to crystallize? Then on start up messes pump up. They also said could be bad run of pumps?

Gordon... There is a "cold weather" process that evacuates the DEF from the lines that run from the tank to the emissions system. It is intended to purge the lines so that they do not freeze. When you shut down your seneca, you usually hear a pump sound running for a minute or two after - that is the process working.

The big challenge is where the DEF will freeze in winter storage and some things go bad. We have been lucky so far... as our winter temps only get to +10 -- +15 at the low end. And I keep the house at +60 all winter long, that somehow seems to keep the parts below them from a deep freeze.

I would expect this to be a fragile system when stuff freezes and is not winterized like the interiors... DEF sucks, but mostly the whole system is not really immune to really cold weather.

Thanks I will inquire about that, am also looking into heated storage for it next winter. If I can find some might be cheaper than another pump issue. The minus 20s and 30s sure can freeze a lot of things up. Considering they said it wasn’t a cold winter wonder what happens when it gets colder?

Considering that DEF freezes at +12F... I don't have a good answer besides heated storage, especially where your winter is. We hated being caught up in the Bomb Cyclone this winter in Minnesota this spring... but we did survive after all.
