13000 miles... threw a P26AB code on the way home. Best I can tell it's a coolant bypass valve. Having the wife monitor the temp gauge on her way home and have a 7am appt at the dealership... Anyone have experience with this? It appears it may be AC system related.

Google the code and look at the cause of the code for the Dodge Ram. It may be a case of the same thing with the Smartie, the PCM needs a re-flash.

Mine did the same thing around 10k miles. I took it in and they replaced it for free. They also had a recall on the headlamps as well. And another recall on I think a nut for the brake.

Good to here all went well

Does anyone know how the valve looks like? Thanks
Or better yet, include the part number too. Without a part number, it is close to impossible to find replacement part. For some reason, I can never find any Smart parts with just the part name. :(

Very easy to fix and install. It's behind the windshield reservoir tank and it takes about 5 minutes to deinstall and install the new one. Also the new valve before install you have to take the small hose off and install the valve with the hose already there . Other wise you will have to do a lot .

Also you need to reset the code.

Thanks for the picture, it is really helpful. Bonus: There is a Renault part # too (149170923R).
However, google search with using the part number "A2812030100" returns "A2812030100 MERCEDES-BENZ, KUEHLM.SCHLAUCH", which, according to google translate, it is "coolant hose".
Something lost in translation? :) No wonder Smart parts are so hard to find.
Where do you order the part?

FYI
As a firm believer of Murphy's Law and want to keep my car for as long as possible, I always on the look out for any 453 problem and solution, just in case I may need it in the future.
So I take a peek at my car's "coolant bypass valve" as mentioned by SAM101. Guess what, the part # printed on the hose is 149175603R (yet another part number?)
