My check engine light was on and the diagnois was to replace the intake manifold & intake flap motor. Due to the $1700 pricetag for this service, I delayed doing it. I tried using Diesel Extreme and it temporarily cleared the check engine light. The light came back on, so I tried using more Diesel Extreme, but my check enging light didn't clear. Then my particulate filter light came on and I tried running at high revs, per the manual, but didn't clear it. Finally I opted to get the intake manifold/flap motor service. The engine light is still on and the particulate filter is staying on. Service recommendation was to replace the catalytic converter (with the particulate filter) for $2K. At this point, it's just not worth the cost for these type of repairs, so if you're getting the check engine light, don't pay for the repair. Live with the light and drive it until it dies.
