Fault code 148a00

[CleverPixel]

I own a 2009 E350 CDi coupe with under 72,000 miles, which I acquired at a low price from a friend a few years ago. It is mostly used for short trips to the gym or grocery shopping, since I work from home. Not optimal for a diesel, I acknowledge.

My engine light has begun to pop up with fault code 148a00, which my code reader states is "The number of times the regeneration of the diesel particulate filter was performed is too high".

The 1st time I reset it, placed 2 bottles of Wynns DPF cleaning in the tank and then drove it down the freeway for 90 minutes. It was satisfactory for a month, but then it returned. I undertook a similar endeavour; however, the drive lasted just an hour, and now, a week later, the light has reactivated.

Is this the DPF itself, or a sensor, and what are my options?

It definitely requires a decent italian tune up every week. Consider incorporating Diptane into the diesel fuel.

You need an individual to clean the DPF and reset the regeneration count.

Thanks. I wasn't sure whether cleaning truly helped, or if a replacement was the only choice.

I'm going to try these folks

Ensure they do the necessary procedures rather than just resetting the soot level and exploiting you.

Utilising the appropriate diagnostic equipment, one may reset this.
Provided that the fill level remains low, etc. You effectively inform the vehicle about the new DPF and recalibrate the relevant settings accordingly.

What equipment is required for this, or is it exclusive to garages?

All issues have been resolved (at last).
