Stop! Stop! Stop!

It has been some time since I have posted here. That is because there have been no major running issues, which belies all the things that friends, and neighbours have been telling me is wrong with this Van. That reputation is down to the way the motor trade has dealt and still deals with faults. By using a process of changing parts to eliminate them as faulty instead of following a procedure to determine what the actual fault is. Then charging the customer for the privilege.

 
The van had not been used for some weeks, so it was quite a surprise that when running it up the road to get some supplies that two red lights started to flash on the dash. The STOP and what looks like an outline of an engine. After the initial annoyance I considered whether I should do what it was saying and STOP. However I carried on. With my mechanics head on I started to reason out what could be happening. To a certain extent it looked like the light was flashing every time I hit a bump, but then it looked like it was flashing for the hell of it! I reasoned – could something be loose? or could damp have gotten in causing a short?  I decided as soon as I returned home, I would look in the owner's manual.

 
With the manual in my hands, I look for the icon page. OK the outline is of an engine. Which means: Engine. stop. See page 25. or Engine electronics, exhaust emissions. See page 26. What does it say?

         Page 25: will light up in conjunction with STOP engine if coolant temperature is too high. The temperature gauge was slightly higher than usual but not off the scale. “It can't be over heating, can it?”

         Page 26: Control indicator lights up when ignition is switched on. Goes out shortly after engine starts. There are then two headings here, one about flashing when engine is running, which is the one I took note of for obvious reasons because it states: For fault that can lead to destruction of catalytic converter. Look to another Page 94. I did look at the other page for reference. Talk about strike the fear of God into you that you now may have a bill coming the size of the national debt. I have got to say I took this statement with a pinch of salt until I knew for sure that all indications lead down this route. If it does oh man!

 
There was nothing I could do as I had a long trip planned for the next day. Just have to see what happens. I know a break down far from home means an expensive tow. I'll cross that bridge when I come to it. The long trip gave me time to think about what could be happening. I've got to say that it was running really well so it cannot be the converter. (As both lights flash for the hundredth time) I looked at the dash from time to time when the lights were flashing but noted nothing else wrong. Then it went out and stayed out for the rest of the trip.

 
The trip home started well no flashing lights at all. Then we hit a major down pour could hardly see out of the windscreen at double wiper speed. Then I noted that the same two lights were flashing again. By the time I arrived home there had been some further developments the head lights were sort of flashing getting brighter and softer I also noticed that the temperature gauge was oscillating in time with the lights. When I turned the engine off, I notice the cooling fan was running.  This is looking like a cooling temperature sensor problem.
 
With the bonnet up it's time to track down this fault. I still have it in the back of my mind that it is a dodgy connection. But until I find this allusive sensor, “where the hell have, they hidden it?!” Sometime later I track it down to the right-hand side of the engine behind a number of pipes with the sensor facing the bulkhead. Now I have to thread my hand through the pipes like a snake (what a joke) to feel if the connector is loose. There is a bit of movement but not enough. After some fiddling, the connection is removed and reconnected. Oh Well here goes. The engine has now been running for a couple of minutes, no flashing lights.  Better take it for a spin to check and make sure. While I'm out I'll get a cooling sensor.  

 

Since doing the connection I have not had the time to replace the sensor due to workload and the fact you have to drain the whole cooling system down. I hope to come up with a solution that negates this, If I do, I will let you know. But I'm happy to say that the red lights have not flashed again. Bad connection!? Time will tell.  

 
When it comes to red lights flashing on the dash, I am not condoning that you should ignore them and carry on regardless. The situation in which it occurs needs to be taken into account and then the appropriate action taken.

  1. Hello. This is an old post, but I'd be interested to know what happened about this problem, since the same lights have been flashing on my vivaro. From what I can tell, it can be many different things. What was it on yours?

    1. Hi, after all this time I have no doubt that this time it was the cooling sensor connection. It can also mean the sensor it's self needs changing.

      Please note that the following was also happening: Head lights were sort of flashing getting brighter and softer I also noticed that the the temperature gauge was oscillating in time with the lights.

      Update: I still have not changed the cooling sensor.

  2. I m not expert, but I believe you just made an excellent point. You certainly fully understand what you are speaking about, and I can truly get behind that.

  4. I am hoping someone reading this can help . We have a 2006 Vivaro which is currently running really well after the MAF and ERG value were changed recently. Several weeks after these parts were changed out of the blue both the red engine stop light and the yellow engine service lights came on and are on permanently whilst the engine is running. A friend with access to a professional engine ecu code reader came back with no error codes. I should mention that the ABS and handbrake warning light are
    also both on, but they have been on for a long time, ABS sensors have been changed and after testing we think it is the ABS unit ( could they be connected ). Just to confirm when you turn on
    the ignition all the lights come on , the glow plug light, the
    the fuel low warning light , the inhibitor/security light all go out after few seconds. The fuel and temp gauge appear to working OK and no other sign of electrical faults. IF anyone has any ideas of what to check it would be appreciated ?

    1. My suggestion is to ( as described in the post) Disconnect and reconnect the plug to the temp sensor and check the wires to it as the wires are known to ware through from the vibration. We had the same fault lights that you describe.

  5. Hi Mitch Thank you we will try this and update with the results.

  6. Just to update this thread. Our fault was down to a faulty ABS unit. But from this experience as least I will know what to check if a similar problem with the service and stop light emerges. Thank you for taking the time and advice it is appreciated .

    1. As I state in the article above you should not ignore a flashing red light unless you are sure what it may represent. Your car your responsibility.
