![]() ![]() Holding a deep socket with my fingers, I snugged them down. Without going through all the things I tested and tried (this thread is already way too long), I discovered that the nuts on the posts behind the temperature gauge were loose. The light stayed on! Back to troubleshooting. While waiting for another “order canceled” email, I checked the relay again. They certainly seem to have disappeared from the vendors' shelves. ![]() The guy at EuroCampers said the manufacturer discontinued them. Yes! Ordering a new one, though, was a problem. When I pulled the Engine Coolant Level Relay, the light went off. The light finally came on and stayed on a few weeks ago. The light blinked for a full day, then, thankfully, cured itself for the rest of the trip. It first appeared when we were in eastern Washington state (we live in Atlanta). I've been confounded by the red blinking light for a couple of years. I read through it all, with special attention to David Beierl's posts, but, I confess, I may have glazed over a few times. Hopefully my solution to this problem is not already in this thread.

My temp gauge light blinks correctly at start up and then blinks continuously again about 30 seconds after starting the engine or having the key in the run position. I have read all of this and still need some help. I have had to replace the wiring connector in several vans to get a reliable connection.Īre crazyvwvanman or dbreiel still monitoring this thread? These can get corroded badly at times and stop making a reliable connection. From there the other wiring pin is a ground wire from there over to the body near the ignition coil.Ī break or bad connection anywhere along that wiring path will cause what you are seeing.Ī common trouble spot is the 2 pins of the sensor connection. From there it goes to the 2 pin wiring connector in the top of the level sensor in the top of the coolant tank. The signal wire to the 42 relay from the coolant tank level sensor has a connection in the engine compartment wiring box, in one of the round 7 pin connectors. That indicates a possible failed 42 relay but more likely a problem in the engine compartment. Posted: Mon 3:53 pm Post subject: Re: blinking coolant temperature LED I will check the signal wire as you described along that routing for a break or bad connection. Is the signal wire tbe blue/green and does the brown ground from the other sender pin go back through the 7 pin connector before grounding under the coil. Wow thanks for the quick response and information Mark.

The main reason being correct continuity//resistance between the sensor pins. I have read that the glycol to water ratio is critical for the coolant low level warning system to work properly and that 50/50 is the correct ratio for a number of reasons. One more question as I dig into this problem today. When there is mostly water and more load driving I have experienced localized over heating which blows out some coolant and then gives a genuine low coolant warning. Maybe none of them had way too concentrated of coolant so I can't say if that would at some point be a problem. Some of those for sure had weak or mostly water for short test periods and didn't experience the flashing led in around town driving. VW says that both conditions can cause it but I have doubts about the weak coolant end of it.Īfter working on the cooling systems on dozens of vans I have not experienced this. Posted: Tue 12:01 pm Post subject: Re: blinking coolant temperature LED I have the GoWesty audible alarm installed and it sounds as well□ When I disconnect the plug connector on the top of the level sensor, the red light flashes after about 25 seconds. I found the BL/G wire slightly backed out of the round 7 pin connector. Posted: Tue 10:41 pm Post subject: Re: blinking coolant temperature LEDįollowed the wire continuity from control relay through the connectors and the low coolant sensor and back to ground.
