  6. Hello Keith,
    This sounds like engine coolant light. Check your radiator header tank for coolant levels. If the coolant doesn’t require topping up, it’s likely that the coolant level sensor is faulty.

  7. alan

    lim came on the instrument panel and then flashed when i drove at 75mph . drove at 55mph for the last 20 mins of my journey to make sure i got home

  8. Jennifer heron

  9. Hi Jennifer,
    I think it’s a symbol telling you that there’s an information message that you need to read.

  10. Daft Invader

    It’s going to be a long boring trip home…
    Seriously, not seen it before/during driving my Vx.Ast.1.6sri. Doesn’t sound serious. Check colour (red/green), and frequency. Flash your eyes when ‘nipping in’ to Vx. garage near home!

  11. Stephen Jones

  12. Barry

  13. Brian Randles

    My 2010 Astra is showing a warning light detailed like an open book with a letter i on the page it also warns of a code 16. What does this mean?

  14. Hello Brian,
    The warning light is telling you to check the manual (book) and the fault code 16 is a brake light failure.

  15. Allan

    Normally it’s something to do with mobiliser on the car what year is your car mate

  16. Mandy

    I’ve got a red door light with a seatbelt (?) across it. The alarm goes off continuously whether or not I’m driving.

  17. Dash

    I have a service light going on while I drive (usually after 40 km drive), while it remains on it causes loss of power and then it goes off and everything is back to normal… Opel Astra 1.7 cdti 2005.
    Anyone has an idea what it might be?

  18. The fault light and reduced engine power / limp mode can be related to the EGR (Exhaust Gas Recirculation) Valve being quite common, but equally it could be many other things. Have you had a diagnostics?

  19. bill

    I have the vaxhull astra with a spanner through it it only come on since I reset my key fob with a opcom

  20. Mathew

    Hi mate I have a Holden Astra Sri turbo 2003 when I drive and turbo kicks in the engine light comes on and car cuts out for a second then light turn off and car runs fine can figure it out

  21. Kadir

    My Vauxhall’s Astra 2018; some times now engine management sign stay on on one or two days and goes off again and after few days come back again and stay again one or two days and I don’t understand why and when I go to garage for help then no sign is there and it is difficult for me to understand why this things happen please help me

  22. Hi Kadir,
    When the engine malfunction warning light comes on, it should store a fault code. Have you had diagnostics done to read any fault codes? The engine malfunction light is generic, meaning there’s many potential faults associated with it. As such, the only way to find out what the problem is, is to have fault codes read with diagnostic equipment.

  23. Kadir

    Yes code is C1221 says Wheel speed sensor front left Malfunction but I been in Vauxhall’s garage and they can’t find anything but now again sign come and after one or two days it gone again , do you think can I change the new Spark plug or please tell me what can I do
    I very much appreciate your reply

  24. Hi Kadir,
    I think the best thing to do rather than keep replacing random parts would be to get your own diagnostic tool. You have have the tool handy to use then. They can be purchased quite cheap now.

  25. Brammy34

    In reply to keith.

    That is for the radiator… Check your coolant level and top up if possible

  26. William Vankie

    Hallo ,sometimes my opel just stop the running engine especially when there is convoy or
    stop and go when the engine is very hot and low gear,please help

  27. Godfred

    After visiting the electrician on dashboard light, handbrake n fuel indicater lights are on n doesn’t goes off pls help

  28. Hi Godfred,
    If the low fuel warning light stays on, it’s probably a faulty fuel level sensor. If you have any light that stays on relating to brakes, always check brake fluid levels first. After that, when parking brake / handbrake warning lights stay on, it’s usually a faulty switch.

  29. Dillon Parkin

    Hi I have a red like dipstick warning light on my 64 plate combo van any ideas ?

  30. Hi Dillon. I thought the red dipstick represented either a low engine oil level, or if the level is correct, a fault with the oil lubrication system.

  31. Tara Paterson

    Hi I have a holden astra convertible 2006 the alarm is going off when I unlock the door and stops when I start the car but goes again when I release the hand break it stops after about 6 seconds, the digital dash shows brake but I can’t read the next word as not all digits are working. Any ideas please

  32. Jamie

    I’m new to the astra j, I have a 2011 1.7cdti
    Turned the ignition on today and heard 4 (tones) then the spanner in car light stayed on solid, leaving work it was on again but nipping to the shop it went off

  33. Hi Jamie,
    Are you getting any messages or just the warning light / beeps? You’ll need to scan for fault codes really, else it’s just a guessing game.

  34. Jamie

    All I’m getting is the light and 4 beeps on start up, but then Somtimes no light.

    There are no messages or warning description on the display.
    I’ve tried my eBay scanner and my next doors even better in depth scanner, but nothing shows and says no codes are stored.

  35. Are you sure the scanners are 100 percent compatible? For what it’s worth, try the pedal test – both feet on gas and brake with ignition off, hold them there then turn on the ignition. See if any fault codes flash up.

  36. Jamie

    Not entirely sure, but both scanners worked on my astra H , and I didn’t think the pedal test worked on the astra j

  37. Anne

    I have a Vauxhall Astra. There is a small red box on the bottom right hand corner of the central panel displaying my speed in large numbers. I don’t think I’ve seen it before. The small red box displays the number 7.

    Any ideas??

  38. Ryan

    However on 2 occasions while driving and it happens so fast, a red long strip light flashes quickly on my dash
    and it happens so fast i can’t determine where but its on the dash panel (took me by surprise as it was so bright.???)

  40. Jackie

    I have yellow light that looks like a cog with an exclamation mark in the middle it comes on when you start the engine and then on off while driving. Can you help please

  41. Hi Jackie,
    The cog with an exclamation mark in the middle is typically associated with automatic transmission. It could be a problem with transmission fluid, overheating or something else. What you’ll need to do is book your vehicle in for diagnostics. This is where they hook up a diagnostic computer to scan your car for fault codes. When fault codes are detected, the diagnostic tool will show the specifics of the problem.
