    Hi All.

    My names Jamie and I just bought my first Vauxhall, its a Vectra 1.6 Premier on a P plate.

    I managed to drive it about 20 miles home after purchase when the engine warning light came on. It stayed on for about 10 mins say then went of again. Once it went off it stayed of for another 10 mins or so then come back on again.

    Its now off again but im worries that the car has a problem so did a google search and found this site as well as another showing how to test the codes. The problem I need help with is I cant find the diagnostic plug. Under the handbreak I have 3 plugs. One is blue one green and they are both plugged into other wires (thats an easy way to explain) there is one other plug that is black and has nothing plugged into it.

    Im assuming that the shall I say spare plug is the diagnostic one. The problem is it does not look like any of the 16 pin plugs like I have seen while looking plugs, what a way to spend enjoying a new car!

    Can any one offer any suggestions please? I relly struggled to get the money for this car now its broken already.

    Thanks

    Hi

    No the car seems fine. i test drove it before I bought it, its done 100k but has lots of history and invoices. I thought it looked great. then as I say while driving home the engine management light came on. If it had done it while on the test drive I would not have bought it.

    Thanks for the reply,

    Jamie B

    Hi,

    There is no cover in the black one. Its an open plug that looks like one of the plugs in the paper clip test pages I have looked at but does not have enough pins? Also the pins look to be in a different configeration to what is shown on the pages I have viewed.

    I just took the car out for a 10 min run. The light did not come on this time at all. I did some 30 mph speeds and also took it to 60 mph. I live near a country lane so I didt break the law ! :rolleyes:

    When I was driving home the fuel light came on as it was low on fuel. Could this have been some reason to casue the light to come on?

    Im worried now that as the light has come on the car will be running in safe mode!! is this the case do you think?

    I need the car for work and really cant affoard for it to die on me.

    I will tell you one thing though. I cant belive I have waited so long to own a Vauxhall. The car does look well good even though it does not seem to be working 100%. I might even say its the best car I have had. And its not even been a day yet.

    Dam I was hoping that as the light was now out and it has not come back on even after driving 15 miles to work today that it was sorted.

    I have noticed now on the one of the links you sent my plug is the same. I thought I should have all the holes with a possible conection but looking at one of the pics they have 7 possible contacts just like mine.

    I will try and pop to the car at lunch and see what I can find. I really hope its not going to cost to much money to fix the problem.

    Apart from this its a lovely car.

    Thanks

    I have a code what does it mean

    Hi Guys me again!

    I have managed to get the light to flash a code at me. There may be trouble ahead!!!!

    The code I have noted is 1 4 10 5

    Now I have looked on the net but cant seem to match this code to any listed. It done this code 3 times so Im sure I counted it correctly.

    Please does any one have any ideas?

    Thanks

    Jamie

    The code you have is 1405 (10 flashes means zero) which for a 1.6 engine comes up as 'Exhaust gas re-circulation (EGR) valve' If I remember correctly, the EGR valve is bolted into the exhaust system somewhere around the downpipe, and is fairly easy to replace. I'm sure someone will be along to point you in exactly the right direction, or do a search on here for EGR valve. The fault will still be logged into your cars computer even if you replace the faulty part, this can be reset at any garage with the correct equipment, or I do believe that 30 or so clean starts of the car (with the fault no longer present) will automatically remove the fault from the computer.
    Hope that helps
