DMGRS Posted March 30 Share Posted March 30 I figured it was time to rinse DPF with Wynn's fluid. It was discovered to have a hole! Check out the picture. It has me wondering whether it may perhaps produce a pressure leak severe enough to fool the computer into thinking the DPF is full. It seems to reason that a larger pressure differential will result in a larger soot calculation, and vice versa; removing part of the pressure will cause the shown difference to be larger. I have 316 electrodes at home, so I'll have to find a nearby welding shop to fix it. Alternatively, I could just buy some 304 tubing and practise on it.

another_clean_sheet Posted March 30 Share Posted March 30 I was wondering if the DPF was made of stainless steel. Quote Link to comment Share on other sites More sharing options...
DMGRS Posted March 30 Author Share Posted March 30 After doing some reading, I would assume so. Mild steel probably wouldn't make it beneath the vehicle for so long. What happened to galvanised ubolt is also clear to me. Quote Link to comment Share on other sites More sharing options...
trikey Posted March 30 Share Posted March 30 If aesthetics aren't an issue, a standard mig welder blast should be enough to seal the joint. Quote Link to comment Share on other sites More sharing options...
vitessear3 Posted March 30 Share Posted March 30 An MoTer could reject it if it appears to have been tampered with. It may be beneficial to consult your partner for his thoughts about it. Does the DPF have that on the intake side? Because a lower differential pressure would result from that. It might lead to a highly unlikely interpretation, though. On my own, I would replace. However, you should inspect the DPF's tail pipe. I received two pairs of female and male items in my purchase. There is a female receiver on my back of the exhaust. Your V5 confirms that you have a Euro 5 vehicle, and your emissions plate details 0.1, so it must be. I purchased one in January from AutoDoc for £310.51; however, it did not fit, but it might have been adapted to suit. Quote Link to comment Share on other sites More sharing options...
DMGRS Posted March 30 Author Share Posted March 30 I got a replacement sleeve and some Gum Gum because I cut it when removing the DPF. You won't even notice the weld. I suppose nobody will care about a well repaired exhaust system as long as the emissions are acceptable. The DPF's back is where the leak is. Also, I really doubt it's a knockoff. Since it was mostly used for highway travel (as an airport taxi), I assume it is still in fine shape. Even though it's not related to this subject, I'd still like to inspect the exhaust pressure hose. Quote Link to comment Share on other sites More sharing options...
