2011 ML350 BlueTEC
Gutted my DPF

Hello,

My 2011 ML350 Bluetec (W164) recently stopped accelerating. As soon as I put it in drive, it died. Brand new battery. OBDII codes were: P2459 Diesel Particulate Filter Regeneration Frequency and P2463 Fault code not found in database. After a fare amount of research on DPFs my solution was to remove it, cut it open and remove the filter/gut it and weld it back together. This is s temporary fix to get it operating again. Im hoping to contact Malone Tunning in Canada this week for a tune quote and to see what they recommend for s delete kit... Husband gutted the DPF and it was packed full of crap, welded it back together and reinstalled it back on the SUV. Getting to the DPF on a ML is a pain.... nothing like the Sprinters from what I watched on You Tube. We had to cut the bolt that goes through the clamp that connects the DPF to the back side of the turbo. Just left Home Depot for a replacement bolt. Keep your fingers crossed!!! Im really hoping it runs/accelerates when we are done this evening. Im in Texas so doing this will not cause me to fail emissions as diesels are a safety only inspection. Wish me luck!

Don't blame you , it's a very flawed device .


I laugh how I hear on an almost daily basis people have to do special high revs motorway trips to clean or force a regen , how's that helping the environment , the NOx and diesel particulates are far from 0 .

A motorway is an hour away from me .

Get the egr out of the new map too .

Don't know what the vehicle registration renewal process is in TX, but if you have an emissions test component you're going to have a problem.

Without a tune , I would think it will still try to do regen ?
Dumping diesel fuel into an empty DPF for a regen might cause an issue.

I'm lucky , that I am local to Buzzken near Toronto ON.
PM me if you want any details/info on the above

For sure get a map to accommodate gutted dpf preferably egr off too.

I wouldn't of thought it would regen post gutting as the pressure sensors wouldn't detect a resistance to trigger one .

Courtney- What ended up happening with this? What happened after DPF was gutted? Did it run right? I am going through similar issue.
