2014年6月24日 · The G611 is really an anti-tamper sensor, that once removed from the radiator is purposely broken. This is done so to ensure that the PremAir radiator of the car is not replaced with a non PremAir radiator, which would violate the EPA emissions certification of the car.

2014年8月22日 · Sensor G611 are met as follows. To check for the presence of the radiator, pre-determined distinguishing features (IDs) are stored in the ECM and in G611, and exchanged electronically. Information is exchanged via LIN bus according to the master-slave principle. This means that Radiator Identification Sensor G611 is interrogated by the ECM.

2014年11月18日 · After doing a little research i found that the g611 sensor meters the conversion from ozone to oxygen from the radiator. Here is a video by PremAir describing the process: https://www.youtube.com/watch?v=81mvAQEGPE0. These radiators act as a catalyst converting ozone to oxygen, thus reducing smog.

The cooling surface of the radiator on some Volkswagen/Audi Group vehicles is coated with a catalyst that helps reduce Ozone, The G611 sensor monitors this function and is part of the federal emissions control of these vehicles which allows the manufacture to receive EPA 'credits'.

Temperature Sensor, this fault refers to - G611- as Radiator Identification Sensor. If the radiator requires replacement on any above listed vehicle, the -G611- will be packaged separately within the radiator packaging. The new sensor will need to be bonded to the radiator. Use AMV 195 KD101 adhesive (refer to

The G611 communicates to the ECM via LIN-Bus, the sensor's unique ID (encrypted) and temperature. There are no Measuring Value Block for this information. Currently, the G611-Radiator Identification Sensor is not available separately, it comes with a new radiator when ordered from the vehicle's manufacture.

It's callout G611 on this schematic. The numbers indicate which pin on the connector which wire goes to

2022年10月19日 · Not hard to find, just a little work to replace the connector with the VW one from the old sensor. It's a G611 sensor, Mercedes part #221905560080. Can be found on Ebay, FCP Euro, even directly from Merc.

2020年9月14日 · They are caused by a faulty G611 radiator identification sensor. The sensor does nothing other than confirm the OEM radiator is installed. This radiator is coated in a catalyst that helps convert ozone; it is used for emissions credits.
