    Exclamation Fabia Won't Start

    Hello Folks!

    My Fabia 1 is giving some serious problems that I've scoured every inch of this forum to find solutions to but every fault i fix causes more problems.

    Here's what's happening currently


    1. If left over night at all, the car won't start from the key the next morning and needs either a jump start or started from the run.
    2. If it's jump started and not driven above a certain rev for long enough. It won't start after being stopped.
    3. If it's jump started from overnight, the power steering pump won't come on when the car is started and the car needs to be left running for 10 - 20 min and be re-started and then the pump comes on.
    4. If the car doesn't need jump started and the power steering pump warning light comes on, the car wont start after stopping.
    5. The back light on the dash will start to go dim, the window wipers will move at the speed of a slow wipe on their highest settings and then the power steering pump will stop working, if the car is stopped after this happening, it will not start again, unless a rev above 3500 is held for about 7 seconds
    6. If the car starts from the key and is kept idle, say for the time it would take to write and send an "I'm on my way home now" text, any use of the brakes, steering wheel or anything that draws current will cause the radio to cut out and the power steering pump to stop working unless a high rev is held once again.


    What we've tried


    • Changing the alternator
    • Changing the aux drive belt
    • Changing the oil filter (needed a change anyway and thought i may as well clutch at any straws I can as this car sends me to my financial demise)
    • Changing the battery
    • Repairing the connection between the alternator and the battery
    • Changing the starter.


    All these things have done is make the engine management (glow-plug) light blink steady when the car eventually does start.

    Personally I think there's a short to ground somewhere or a bad ground for that matter, but everywhere they seem to commonly occur on these cars yields either something we've already fixed or is fine to begin with.

    Any advice or insight (other than turn it into a cube) would be appreciated

    Does the charge warning light come on with the ignition?

    The alternator warning light comes on when I turn the key to the stage before ignition and stays on until that car starts and then it goes out.

    Hmmmm, OK, OE radio?

    The radio is an aftermarket one, have tried it in every wiring configuration in case it's draining the battery even when it's off and am taking the faceplate off every time I leave the car

    Do you own and know how to use a multimeter with a 10 amp current capability?

    Used a digital multi-meter in voltage mode and got the following readings;


    • Voltage across the battery, engine off: 12.6V
    • Voltage across the battery, immediately after starting: 12.6V
    • Voltage across the battery after holding 3,000rpm for 5 sec: 14.2V(This reading and the one above prompted alternator replacement mentioned in the main post)
    • P.D between +ve battery and alternator casing (car running): 0.2V


    I haven't measured any current at any point but my theory of the radio draining the battery by somehow staying powered after i remove the key was disproved satisfactorily to me by the fact that the USB port in the face plate that provides power ,to connected devices, doesn't provide power after taking the key out and definitely after removing the face plate.

    Yes current is what we need to know. Take off the earth terminal and connect one probe to it and the other to the post, use a clamp of something similar. The put the post lead into the common DMM connection and the 10amp curent shut side onto the cars earth lead, if this shows negative it doesn't matter but swapping it around will chnage the polarity. You need to trick the car into thinking the bonnet and drivers door are open so flick over the latches to simulate this. Lock the car using the remote (it may have an alarm so stay away from the open door) and watch the current drain, after a few minuets it should drop away to virtually nothing, no more than 0.05amp ish. If it doesn't start by removing the fuses on the battery to see if it is the inside power feed taking the drain, I have seen alternators taking a drain. Then go inside and remove the fuses one by one until the drain disappears, this will tell you the circuit which has the problem.

    Note, to avoid blowing the DMM internal fuse when checking voltage, after doing a current drain test, remove the probe from the amp port and put it back into the general one.
