Not presently. Straight pipe . Maintenance/trouble shooting dpf.

Thanks. Was mainly concerned with theory and expertise feedback on "all oil is burned inside engine, before turbo, hence if oil is present at turbo exhaust side, it is the turbo itself leaking"?

Found this below. Is this what is meant by run-away ? Is the theory correct? "Diesel combusts anything that is oil based because of the high compression, so all the oil from the breather, rings and such would be burned inside the engine, but there shouldn't be any oil on the exhaust side...

Understood. What about oil pressure in order to confirm worn out rings or valve seals issue; there no other way to diagnose but to take apart and look at condition? Is there a way to monitor oil pressure with vcds or something similar?

Thank you! So besides the oil signs, there no other symptoms as far as how car runs and such, again assuming its not a turbo issue. Would there be white smoke or soemthing or would the dpf be filtering all that, hence no signs?

2013 Passat tdi, 2.0. Besides a failing turbo, what else may cause oil at the tailpipe? There is none present but just wondering in case something comes up. The turbo is the first thing that connects to the exhaust so whatever end up at the exhaust end must pass thru turbo first, right? So if...

Quick question: I disconnected the control line (hose from differential press sensor leading into particulate filter) drove car around the block and got P0029 turbo boost range not reached or something to that effect. Is this to be expected with that hose disconnected? Just want to be sure...

My bad. Yes , the intercooler, yes . I thought it's air passing thru there and it's cooled. Anyway, is it normal to have some oil there?

Referring to restrictions in the hose/lines. And yea, not sure validity of this but I stuck smoke hose fitting into dpf pressure sensor hose leading directly into dpf. I can feel the air from the smoke machine coming out of the temp sensor fitting on the downpipe of dpf , but don't see the...

I never performed the smoke test previously mentioned since turbo went out and needed replacing. I will today.

Posted auto scan. Also, am concerned that if DPF is plugged it will damage new turbo in no time, which I suspect is what happened to old turbo. Does this happen right away? The buzzing sound old turbo was making was happening for coupple of years before finally turbo started leaking so that...

Figured it out. Why there wasn't a seal there before, I don't know. Test drive for about 6 miles. Got P 2459 again with soot levels only at 17g, so didn't even reach 24g like before but got the fault code. Will be driving longer trip today see what it does. It did smoke out exhaust pipe briefly...

there is that chrome seal that came with kit. It says ot goes inside dpf, item 7 on diagram. It didn't have one before. Also says note installation position. Anyone know how it's supposed to go? Also, there is that o ring which I found no replacement for.

Im about done with new turbo install. Is there something else I should do before putting back all components? There is no sign of turbo mechanical damage such as broken turbine or anything else that would have sent metal in. Also, before positioning the dpf for installation, I want to check for...

Dealers usually hard to get this info from, but I got it. 03L 253 010JX. This they said is the most current version for this VIN/vehicle with previous ones phased out. Thanks!

Thanks. I see that same part number on other retail websites too. So this is the part number that replaced the oem, i guess; 03L 253 056.? The E V500 letters/numbers are probably insignificant?

The one ending 056 E V500 from original turbo on engine right now. Printed.on blue laminate placard . Even says "part number " . There other letters/numbers such as serial number and such

Looking for turbo. My part number is 03L 253 056 E V500. Have found some but part numbers not exact match, for example 03L 253 010J Turbo BV40 54409880035. It still says for 2.0 TDO CKRA engine as well as for other mentioned type engines. Is this variance to be expected or should one stick to...
