No luck getting anyone to look at it until Monday so farAdd a gallon (4 liters) more DEF
(did any of the "service departments" provide a scanner readout of codes?)

Are there 2 sensors? Because it was still showing 1/2?It finally noticed the refill.... [emoji106]

p.s. your level sensor may be faulty ... you might get it looked at if it recurs
Sound familiar?i If you switch off the engine at a low outside temperature and add DEF, restart the engine after refueling.
If you leave the vehicle parked without restarting the engine and the DEF freezes in the DEF tank, the onboard computer will only be able to register the new fill level after a defrosting period of up to 60 minutes. During this time the engine may only be operated in neutral.
Page 321:MB said:If the DEF level drops below 1.5 US gal (5.5 l), the first warning message is issued and a warning tone sounds. After the message appears for the first time, and under normal driving conditions, the remaining DEF supply will last for approximately 1000 miles (1600 km).
If a reserve mark of 0.8 US gal (3.0 l) is reached, a second warning message is issued and a warning tone sequence sounds. After the first message, the DEF supply will last for approximately 1200 miles (1900 km). Subsequently, you will only be able to start the engine a further 16 times.
You should immediately add 2.0 US gal (7.6 l) of DEF (Y page 147) or have the DEF supply reservoir filled at a qualified specialist workshop.
When the number of remaining engine starts is 0 and the engine is restarted, the engine management prevents the vehicle from being driven at a speed exceeding 5 mph (8 km/h).
If the;Check Engine indicator lamp lights up, the exhaust gas aftertreatment is faulty or an emission-related malfunction has occurred (Y page 211). You will then only be able to drive a maximum 50 mi (80 km) before the engine management restricts the number of starts remaining.
Where to get owner's (and operation) manuals: http://www.mbvans.com/sprinter/owners-resources/owner-manualsLow ambient temperatures
DEF freezes at a temperature of approximately 12 F (-11 C).
The vehicle is equipped with a DEF preheating system at the factory.
Winter operation is therefore also guaranteed at temperatures under 12 F (-11 C).
1 gallon (US) per 2000km is about 1200 MPG ...DEF consumption
For vehicles with a 4-cylinder, in-line engine (OM 651), the DEF consumption of the vehicle is:
* as a Cargo Van/Passenger Van, approx. 2322 MPG (0.2 l/100 km)
*as a Cab Chassis, approx. 1720 MPG (0.35 l/100 km)
For vehicles with a 6-cylinder, in-line engine (OM 642), the DEF consumption of the vehicle is:
* as a Cargo Van/Passenger Van, approx. 2322 MPG (0.10 l/100 km)
* as a Cab Chassis approx. 1720 MPG (0.14 l/100 km)
In each case, the stated consumption figure is a mean value between urban and extra-urban driving cycles. The consumption figure does not refer to a specific vehicle, but is provided for the purposes of comparison between different vehicle types.
DEF consumption, like fuel consumption, is very dependent on the driving style and the operating conditions. This means that the real consumption figures during operation of your vehicle may deviate from those stated.
It's likely. I think Aluminess actually changed their aftermarket bumper design as several people with those were getting the low intercooler efficiency warning too. (From the additional coverage of the bumper.)Possibly due to the winter front I purchased from star and installed?
