    2014 CTD Error Code P21DD Emission Reductant Tank Heating System (urea)

    Hey everyone been a while since I have posted here. Well I'm up to 80k in mileage on my cruze and my check engine light just came on. Since currently I'm 100 miles away from home I felt I little choice but to pay 20 bucks for the onstar protection plan to see what could be up with my cruze. (i know i need to get a OBD reader) Anyways Onstar informed that the code the error code that was transmitted to them is a P21DD Emission Reductant Tank Heating System (urea). Which from what I have heard on means something is wrong with my emission system. Can anyone provide any more detail in this error. I assume that I'm going to have pay to have a sensor or something to that matter replaced. Thanks for any guys!

    Not the same car, but probably the same code. Looks like your DEF tank heater or something in that area

    And here I thought I put a lot of miles on a car every year! I'm impressed with 80K on a 2014 ... and I was freaking out at putting on 60K in 20 months. Best of luck and hopefully it'll be covered under factory warranty if it's emissions based. Other than that, how are you liking the Diesel version? I just can't bring myself to spend the extra $ on the TD version when the Eco gets nearly the same or better mpg ... but then again, I've yet to drive a TD Cruze

    I dont think i will go back to owning a gasoline car/truck again. I look forward to driving it everyday to work. Diesel has over 100k on his CTD. Is the emission system covered under warranty? I don't look much in to it and figured I would have to shelling out some for it anyways. The shop is also going to update the cars software to fix the sticky feeling from the steering wheel when driving on the highway. I thought that the steering column had to be replaced.

    I have 114K miles on my diesel Cruze and I can wholeheartedly say it's worth the money. It is an amazing cars in many ways that can't be expressed simply by the MPG. If you are interested, a few weeks ago I did a writeup on this forum on what it's like to drive 100K on a CTD.

    Dealer diagnostic said the sensor was bad and the whole DEF tank needed to be replaced. $430.00 to have the thing replaced with labor. Anyone on here think that sounds right? I'll get my estimate here in little bit.

    The tank assembly is relatively expensive, so the price doesn't sound too far out of bounds. However, once you pull the trunk floor, the tank is in plain sight and it should just be a matter of a couple screws, a hose clamp or two and un-plugging/re-plugging electrical connectors, so if you have any experience with car repair, or even if you've repaired a desktop computer in the past, you might consider a DIY tank replacement, once you've verified that it's not possible to source the sensor without buying the whole tank assembly.

    Please keep us posted on the part numbers. I don't see a sensor listed separately.

    stopped at the dealership this morning and got the part number they ordered. its 22978800 or number 15 on the illustration. I ordered it from another gm parts supplier for 155 including shipping. Saved me $71.00. This might be something I can replace myself if need be and if not it the dealership said its $130.00 to install. Also I got a BlueDrive OB2 scan tool for $99.00 from amazon. I cleared the code and so far it hasn't come back on it being so warm out I assume the error code might not come back until the cooler temperatures come back.
