Thanks to everyone for help and good wishes. 

I'll report back on the smog test.  The entire emission system is there, so there's a reasonable chance it will pass.

As a matter of interest..did they detail what was wrong or was it just "Repair WUR"?

And are u happy to tell us what it cost inc freight//levies/state/VAT etc!?

They sent me a different reman unit they had in stock, so I don't know what was wrong with the original one.  If I asked, maybe they would tell me once the have the old one and open it up.

The total cost to me was about $296 US after returning the core.

Can I ask what code your WUR is?

I've got a (euro) '77 280se and can't work out whether I have the correct unit. Some places say yes, others no.

The last 3 digits are 101.

According to my understanding the WUR 0 438 140 101 fits the later models of the 380 SE/SEL/SEC/SL (W126/W107) and 500 SE/SEL/SEC (W126) and 560 SL/SLC (W107).

Your 1977 280 SE W116 should have a WUR ending with 030 or 031 or 041 (for the weaker engine 101-105 kW) or 010 or 057 (for the more powerful engine 130-136 kW and depending on month of production in 1977). Again, this is according to my understanding.

I believe the EURO 280 SE W116 09/1977-07/1980 shall end with 057.

Do you know the production month?

Apologies, my WUR code is indeed 010. For some reason the reconditioning places list the 010 as belonging to the coupe but not the SE. I don't know why there's so many versions of the WUR but there you go!

EURO 280 SE W116: 010 is correct if your car i produced between 08/76-08/77.

The information from the MB parts catalog and Bosch catalog is a bit confusing ... I must admit. 010 seems to be right ... but could also be 057. Maybe they are quite similar?

Recommend to discuss this with a specialist dealer.
