Service card for OBD point required.

[Scott1433]

We have sent our Mercedes Sprinter van (2019) to a local company for MOT. However they have said we need to take it to a main dealer because they cannot access the obd port without the key. For whatever reason, we do not have this key. I spoke to mercedes who said these locks are not factory fitted they are supplied by a 3rd party so they are unable to supply the key. They said we need to get it from the 3rd party company, and there should be details near the port. There is a label near the port which I have attached to this post.
The problem is when you go to this website it doesn't appear to be an active website, you just get forwarded to useless websites that have nothing to do with this. How to I obtain a new key, seems like a crazy situation, I'm just going round in circles. Sorry if this is a dumb post, but sorting out vehicles is not my normal job, but this has landed on my desk. Can anyone point me in the right direction of how to solve this problem?

Why do the MOT test station need to access your OBD port?
I've never heard of this for an MOT.

It appears you can get a new card from this site who have taken over obdcard.com

Any diesel vehicle with a DPF now requires both the oil temperature and the engine RPM to be measured during the emissions test. This is done with a connection to the OBD port.

Thanks for the explanation G.

Is that a recent thing? My ML was MOT'd in Feb & the tester didn't plug it in

Maybe too old. Usually they’ll do this if you have a small number slap bang in the middle of the chassis sticker inside the driver’s door shut that is lower than 0.30. If there is no number on your chassis sticker they will test it to the default 0.30 figure, and that doesn’t require the plug in to the OBD port. The OP’s 2019 registered vehicle will definitely have a much lower test threshold

Must be tool old then .... mine is 0.51

0.51 is a high number for that age. My ML is 0.51 and I have no DPF. I shouldn’t tell you this, but if you have a much lower target number on that sticker if you scrape it off they have to test it at the default number.

I'd assumed it did have a DPF due to having Adblue .... but never crawled under to look

Did you try the last company that owned it if you havent got it that long? maybe an ex lease hire company van that possibly still have the keys? Never heard of this, good to know. ive heard of another obd lock that can only be accessed by the dealership but not a third part one.
