053296 - Local Databus
U1030 - 000 - Electrical Malfunction - Intermittent

009576 - Sensor for Ozone Reducing Radiator Identification
P2568 - 000 - Implausible Signal - MIL ON

008577 - Performance Malfunction in Cooling System
P2181 - 000 - - Intermittent


I brought the car to the local VW dealer, they said they would try replacing the whole radiator to fix the issue. I passed on this option for a second opinion.

At my local independent, he said the issue was a sensor and that maybe APR could turn off the codes with a custom Stage 3 flash.

I don't have any issues with driveability or performance. I daily drive, track, time trial, and sometimes autocross this car. And I have never had an issue with overheating or the car going into limp mode.

Should I have the independent replace the radiator or should I try the sensor, 8P4965873A, that goose mentioned? I believe both options would be a dis-assembly of the front end.

Thanks.
were would you buy the sensor from? would you get it from the dealer? because i cant find it anywere.

Neither could I. I guess I have to shell out $300 for a new radiator and sensor.

I had to buy a brand new one a few months ago after mechanic broke the probe on the sensor during FMIC install. Based on the google search the only place where you can buy standalone sensor without the radiator is in Russia, go figure why. Russian GTI model is different from CBFA and are not required to adhere to same strict emission standards.

That's right. Though I made some changes before attaching new sensor to the radiator. The radiator and sensor are separate in the box. VW designed this thing in the ways that once sensor is attached to radiator, it's virtually impossible to remove sensor without breaking the probe (some members were lucky in doing just that). I used this opportunity to drill out threads/barbs in the hole where sensor probe goes, so if needed I can remove sensor without braking the probe if need to. I used thermal paste to ensure the heat transfer since the hole is now slightly larger. It has been 5 months now, no CEL and no issues so far.

I will be in Russia this July, maybe I should just pick a few of these standalone sensors to help a few members not to spend money on the new radiators.

great, might honestly pick up a radiator from a junk yard. what are the odds it would have the same issue?

There are not that many people who have issues with the sensor as you might think. Most of the people like me broke it by accident during installation of FMIC.
So i think it should be safe to pick one up from a junk yard, but make sure that sensor is physically OK.

Well I got my sensor installed, turns out the older one which I assume is for a mkV has a shorter wire

If I had time I would have picked up some connectors and made a proper extension but I spliced in some wire from the bad one. Turns out the wire was crushed causing the intermittent short. No idea when this could have happened ad my car has been to multiple dealerships and has had some front end damage both from Street parking and hitting snow berms at speed., either way it was enough to get rid of the CEL and let me pass inspection.

The one I installed was 8P4965873A and the one that was on the car originally was 873B
