Hey folks I'm new here! I got a 2014 Ram Van Promaster Diesel and all was well for the first 10K. Now I have a P208B and P203E code. I saw on another thread someone mention using distilled water to dissolve the crystals for the P208E code but would this work for the P208B too. The manual says of coarse to replace the whole tank and the stealership wanted 3800.00 for that. I found them for $1900.00 and it looks simple on the van to drop and replace if needed but that just seems over the top.
