Vectra 2.0 TDI 1998 management light - wemyss
Yesterday morning the management light went out along with all the others when the ignition was turned on.
Started the engine and it came on. Stopped the engine and this time it stayed off to the end of my journey but later in the day on return did the same.
This morning the same again did the same although this time it stopped on until the end of the road so it looks as if I?m in for some trouble.
It runs perfectly normal with no limp home mode although it wasn?t on long enough to be sure.
The last time the light came on was eventually found to be the CAT had collapsed after main dealer had it for almost a week. And cost a packet.
Will have to take it down to the garage of course but in the meantime any ideas from our residential experts on what its most likely to be.

I have no idea. As no-one has responded you could check out

www.vauxhallownersnetwork.co.uk

There is a specialist vectra section. Some of the guys on there may know. Could wait for the Dynamic Dave. Seems to have the knowledge, sepecially with the vectra.

Unfortunately not with diesels. Sorry.

Trial and error excepted, the only true way to know what the problem is, is to have the fault code read out by someone with a code reader.

I tend to agree with DD, although I think it is worthwhile checking all the vacuum pipes and connections in tedious detail. A split or crack in these pipes will cause problems.

As you say there is no noticeable lack of performance or running problems,then the fault could be associated with the glow plug circuit.hth

Thanks for the replies.
I did a check on the vacuum pipes today but could see nothing. However will do it again with tedious detail this time as NC suggests.
How would the glow plug circuit affect it elekie ?. I think I've seen you mention this before but have never understood the reason this can bring the light on when they arent in use in the summer.
Any way how do I can test this possibility or is it best left to the garage.
Will have a look on the Vauxhal forum however.

wemyss,

Not sure if any of the replies (or the links) in the following post will help you at all. There are some suggestions of the MAF sensor in one or more of the links, but that tends to also make the car feel sluggish.

On initial start up the engine control unit "checks" the various parameters of the system.The glow plug circuit included even though they would not operate this time of year.Same applies to Abs system.

Had the fault code read yesterday by my local independant.
It read "Glow Device General Error"
He siad it could mean that the Glow plug controller could perhaps be faulty but couldnt be certain.
He removed all error codes and suggested that I leave it for a couple of weeks and have it read again to see if the same fault came up. His thoughts were also that as it only came on when the car was started from stone cold it was something to do with a temperature sensor. This morning it once again came on for about 30 seconds.
After a journey it stood for several hours before starting up again and as usual it didnt light up the management light as it wasnt completely cold.
Any ideas on this ?.
wemyss.
