Van Life - [Sprinter Flexi Pipe Repair]

[@nothanks6859]

I've just been quoted £2000 for this job on my Sprinter. "The problem is that the sensors always break when we do this job" - looks like there's no need to remove those, this video just showed me how the exhaust system can be removed without removing the sensors from the exhaust. Thank you Modular Hippo!

Hi NoThanks - Really happy to hear that the video has helped a fellow Sprinter owner!! Made making the video all worth while:) Thank you for taking the time to commenting. Need to tackle some new issues soon so stay tuned (gear leaver hard to operate, Screen Wash pump gone and finally some lovely rust fixing as she is getting old now):) Happy Sprinter-ing!!

Was this causing any driving problems like limp mode or loss of power

[@modularhippo]

Hi Michael - Don't think it did. Saying that, I have intermittent limp mode problems lately down to some sensor issues but it comes and goes so have not paid to much attention to that one yet. As I only replaced a broken flexi-pipe with another and no electrics involved I think it should be fairly safe:)

Can you tell me how the DPF connected to the exhaust? Once you installed your new flex pipe it was time to connect it to the exhaust, that’s what I want to understand. Do they just slot in together and then you clamp it? No welding?

[@modularhippo]

Hi - Unfortunately for me it required welding at both ends of the flexipipe. Believe you can see weld points around 10:10 in video. The outer diameter of connecting ends were the same diameter so a weld was straight forward. I guess that I could have slid a larger tube on top and clamped both sides as very little load on the parts once re-attached to van so guess you could do either or:)

@@modularhippo Thanks for the quick reply. If it was a new DPF and new exhaust, then would the normal procedure be a clamp to connect both? No weld?

@@6969SpAcE6969 Please ignore previous response as now is coming back to me. The exhaust side of the flexi-pipe originally has a bevelled end (6:45) on it that fits to the exhaust part and they are clamped together. Unfortunately the new generic flexi-pipe I bought had straight end so could not be clamped with original clamp which is designed for the bevelled ends, so I cut the bevelled end of the previous flexi-pipe and welded that to the new flexi-pipe (9:15) so that I could clamp it all with the original clamp that the sprinter came with. On the catalytic side the flexi-pipe is originally welded together (in other words, flexi-pipe is permanently fitter to catalytic converter and that is why it would have cost an arm and a leg to buy the whole package as really only needed the flexi-pipe). Hope helps:)

Is there an issue with people stealing catalytic converters where you are? Where are you located?

[@modularhippo]

I live in North Wales - it was more a problem a few years back as not heard anything about catalytic converters theft in resent years (luckily):) - Some valuable metals in them that recycling centres pay good money for.
