    I have a 2003 Opel Astra Njoy that has been giving me trouble lately. When I start the car it will run for a few seconds, shudder and then stop. No warning lights will come on when the car is running and shuddering. I have had two mechanics on separate occasions from the AA come to have a look at it, they checked it over and could not find anything wrong with it. Four months ago I had to get the fuel relay replaced as the car was having roughly the problem.

    Sometimes this problem will occur and other times the car will run fine, when I brought the car to the local mechanic yesterday morning he popped up the bonnet when the car was running and shuddering, and somehow managed to stop the car from shuddering (without the use of any tools or equipment), he seemed to have found the problem at first and handed it back to me yesterday afternoon but now the problem has returned yet again. I have also had to get the EGR valve blocked off about a year ago because if I recall correctly the car was also having trouble somewhat like that back then as well.


    Any help would be greatly appreciated.

    I suggest you contact the mechanic that initially fixed it. Perhaps it's just a loose hose or similar, but you need them to tell you how they fixed it.

    Thanks for the reply biko. I'll give them a call tomorrow and see if they can explain what they did and how it was fixed. I'll have to bring the car back to them to get it checked again and see if it can be fixed, which will likely be on Saturday.

    One of the mechanics from the AA tested the battery and the reading came back as good.

    No,

    This sounds like you've lost your immobilizer chip from your key. It's a safety feature to stop thieves. Did you mess with the keys, if it's lost, you'll have to contact an opel dealer.

    I know the same issue happens on my car if I leave one of the coil packs unplugged.

    The car will start, run on 3 cylinders (juddering) and will stop after a few seconds.

    Perhaps it's just a bad connection?

    The thing is though that OP says the mech fixed the problem by doing something in the engine bay using no tools.

    Hopefully OP will come back with the answer in case it happens to someone else.

    I'll try to get the car to the mechanic today & hopefully it can be resolved tomorrow or Wednesday, if not it will most likely be Saturday.

    I got the car back from the mechanic today, he changed the EGR valve yet within five minutes of driving, the problem started yet again. I am thinking about bringing it to an Opel garage in the hope that they will have some equipment specific to Opel cars that may be able to detect the problem and get it solved. I'll post an update before next Saturday.

    (10)P400 FAULT CODE EGR VALVE

    The EGR valve error might be a symptom of a faulty ECU see the previous post for more information.

    When it shudders to a stop, how do you start it again? Is a fresh turn of the key enough or do you need to push/jump it?

    Error codes? The pedal test or paperclip test will tell you.

    You say it doesn't always happen. Does it happen randomly? Or does it happen after short journeys?

    When the car stops turning the key gets it to start again but within a few seconds the problem will reoccur. I tried the pedal test and the warning light with the car and spanner showed -

    1 [pause] 4 [pause] 10 [pause] 5

    If 10 = 0 then the code is

    P1405 DPFE Sensor Upstream Hose Off Or Plugged


    Lastly it happens randomly when I start the car.

    Although the fault code that I am getting is 1405 when checking up this problem online the ECU seems to keep coming up so thanks for those links.

    I brought the car to an official Opel dealer on Thursday, they phoned me later that day and said that the issue was to do with the EGR valve. They said it would have to be replaced and it would cost €285 (this also included getting the car serviced). I said to go ahead with the work. I got the car today and have drove it for roughly two hours in total and the problem has not occurred once.

    I'll drive it on the motorway tomorrow and see how it performs. If anyone has a problem similar to this then hopefully this will help.
