We have a check engine light going in the Sprinter
2500. Took it in to get diagnosed at an independent service outfit. They came back with an error code of P20BD. Based on what I see in the forum, this indicated a DEF heater issue.
JA: Does the light stay on, or does it blink?
Customer: Let me find out.
JA: What is the model of your '500 Mercedes?
Customer: Staying on all o fthe time. 2500 Sprinter, 171" hightop
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: We'd like it repaired in the most cost effective way possible. Haven't tried anything yet.
JA: Anything else you think the mechanic should know?
Customer: We have a mechanically inclined gentleman or two on our staff. Depending on difficulty, we might be able to do it ourselves. How much would we be looking at for parts. I see you indicated it would be about 1.5 hrs labor.
