Hi All,

We have a 2005 Diesel RV. A check engine light has come on and off.

Seems you need a ScanGuage D for this job of CEL analysis.

Do those of you with ScanGuage D knowledge suggest spending the $150+ to buy a ScanGuage D.

??? reasons ???

Thanks in advance

What type of RV/Diesel do you have and what protocol is being used by the manufacturer-OBDII, J1939, or J1708? It appears as if the Ultragauge is only OBDII compatible?

I have been using the ScanGauge D now for several years with the 9 pin J1939 protocol. Of course being able to read codes is an advantage and being able to clear them is nice but, I do appreciate being able to watch specific sensor values during operation that are not available with dash gauges on my Freightliner chassis.

I have not used the Ultragauge as some have suggested so, I cannot speak to it's performance. Can't argue about the price if it will do the same. I have had good performance from the Scan Gauge D however.
