Default Noob questions

I just picked up a 2011 MB 2500 sprinter. It has 235,000 km on it and from what the seller said, it's all original. It drives well but needs a bit of work to pass the safety inspection. A few things like the brakes and and a few defective bulbs.

When I was doing the test drive, I noticed the CEL was lit. A scan revealed a problem with GP2. I did a clear and re-scan and have now come up with the following "permanent codes": P2005, P22A1, P0673 and P229F.

From my research, apparently they are an intake runner issue, a bank 1 sensor 2 NOx sensor, GP3 and some other code, respectively.

A few questions: can the maintenance interval be reset by me or is that some dealer thing? I am confused about the re-learn requirement for a NOx sensor. Is it just a question of replacing and driving until the ECU figures it out or is there a calibration required?

From what the seller disclosed, the glow plugs were replaced at 210,000 KM, though how many is the question. Not sure about the controller though. Lots to learn, I suppose.

Not qualified to answer your questions but here's some resources.

A lot of stuff from the last published paper 2007 service manual carries over to 2011. Only 12,732 pages.

Just had a look at the manual, which is exactly what I was looking for..... Every manufacturer seems to have a bag of stupid engineering tricks.... case in point, to change the parking lamp, you can't do it without removing the lamp housing, which can't be removed without removing the front grille and the support for the front fender. Almost as bad as my Audi which required the removal of the entire front trim consisting of grill, bumper cover, fender liners, front wheels, etc....I hope I don't learn to loathe this vehicle!

Yes, there are many quirks related to Sprinters. The biggest headache may be the Adblue Exhaust After-Treatment system and dreaded start countdown resulting from allowing DEF low level warning to activate. This issue may have been resolved with SCR firmware updates. Keep DEF TOPPED-OFF. NO spill suggestion here. (https://sprinter-source.com/forum/sh...495#post626495)



More info here: http://www.autocats.ws/manual/sdmedi...002_001_en.pdf

Another, is related to interrupting DPF regenerations. My experience is if regenerations are interrupted three times, it will threw a code and ignite the CEL/MIL. Fortunately, after some highway (couple of hundred miles) driving, the DPF completed regeneration and the CEL self-extinguished.

Per CVtek (https://www.cvtekinfo.com/CVTek/) The following emission components have been revised:
2 NOx sensors. Q-level 5.
Pressure differential sensor.
Exhaust back pressure sensor ( there are two configurations, ECU specific and not interchangeable).
DPF brackets upgraded due to cracking. (verify model applicability). There is a specific installation procedure to minimize excessive component preload particularly to flex joint and turbo union.
DEF tank heater.
DEF heated pressure delivery line.
ECU/SCR module firmware revisions.

This is also important and can save you thousands of ducats. Note: On earlier models the clean air tube must be replaced to match the exterior profile of the new turbo seal. (See WIS for details ). More info here. (https://sprinter-source.com/forum/sh...ad.php?t=48673)



This is an excellent resource. Although there are less expensive alternatives, the thumb drive was easier to install than multiple DVD's. (https://sprintermanual.com/shop/spri...nload-edition/)
