    I have always kept the pedals pressed on the 3rd go until it resets.

    Yeah that doesn't work for me either I'm afraid.


    The countdown reached zero today, so now i have a constant flashing spanner next to the fuel gauge, and a new item, the car with spanner warning light on the display in the middle bottom of the clocks.

    I plugged in my delphi ds150 and read some things.

    Accelerator pedal range, 0% to 139.5% (weirdly!)
    Track 1 and 2 read different maximu. voltages however?

    Brake pedal switches simply read activated or not rather than a voltage or percentage.

    Is there anything there that could prevent the reset?

    What are the maximum voltages for each track on the accelerator.? Pretty sure it's the same on Vivaro's that one track should read half of the other track.

    Ok here are the figures i took today from the delphi, and the latest drama too!

    Accelerator pedal sensor 0 - 139.5% at the floor
    sensor 1 0.74v - 4.57v
    sensor 2 0.37v - 2.28v

    brake switches x 2 are simply shown to be active or none active

    So it looks as if the sensor readings are normal, but here's the latest.

    The van is now in limp mode, with the following lights on

    0 miles to service shows, spanner flashing permanently in the digital display even whilst running, and car with spanner permanently illuminated in the lower display

    now showing the heater coil light in the lower display since entering limp mode.

    I read the code P253F with the delphi, Low Oil Quality, and it won't reset.

    Even though i know the van hasn't done many miles since last changed, i have changed the oil and filter anyway today, but nothing has changed, all lights and limp mode as above and still cannot reset the fault code or service interval.

    I drove the van around a 12 mile round trip, stopped and started it a few times, and ended up at a fellow garage, who plugged in his new Autel reader, and he got the same code, the same interpretation, and couldn't reset it either.

    Am i right in thinking that Oil Quality is actually a calculation from service times / resets rather an actual sensor i can locate, remove and clean or replace?


    The latest drama all occured over this weekends use which was a car transporter trailer job of some 400 mile round trip. It all started well but the last 40/50 mile seemed to bring up this oil quality issue and limp mode.

    Could i be right in suspecting that the load from towing could be affecting the dpf, which in turn triggers an oil suspicion?

    Just in case i measured the dpf at 6.5g clog quantity but have no idea what it should be or what bearing it could have?


    please help! van needed!

    here is a short clip showing what lights are illuminated at ignition, and these stay lit throughout driving now in limp mode.

    We used to have a fleet of three or four Coca Cola vans that used to visit my old dealer on a regular basis - all 2.5 Vivaro's that were constantly having oil changes due to the DPF depleting the oil life.

    The fault code will not erase before the service light is reset - only then will it clear - and of course this is where the issue lies in the reset procedure you're having.

    It is a calculation for the oil life yes, so once it's reset the ECM works it it based on driving style, how many regens have been attempted/completed etc...so obviously because you haven't been able to clear the light this is why it's gotten to the point of further issues now.

    From memory the pedal voltages look fairly good (I'll check later) - the 130 odd percent reading for the accelerator might just be bad interpretation by your scantool. As an idea what you *could* try is to have your scanner available with the data list showing - try your normal reset procedure but only press the throttle until it shows 100% on the list - not a guarantee but worth a try just in case the throttle is reading incorrectly.

    Thank you for your detailed answer and experiences Nick, its good to know you've had the G9U 2.5 specifically too, as knowledge on this unit is thin on the ground compared to the others for sure.

    I have already tried your suggestion, and managed to hold the accelerator pedal steady at 100.2% whilst pumping the brake, but no difference i'm afraid.


    If i could get the bloody dpf/cat off i would gut the things as i tend to do with my other diesel stock, best thing for them in my opinion, but access to the turbo mount is nil for me personally, having no ramp and an average tool selection, its a no go at the moment.

    An independent Vauxhall specialist has suggested disconnecting the clock binnacle for some time to erase the memory of the oil quality error, but i have had the battery off twice to attempt a reset which hasn't worked, so i'm not sure how this method might be different but i'll give anything a go!

    The same folk claim that Tech-2 will be able to erase this P253F code and reset the service interval regardless of the pedal process failing, but i was under the impression that the pedals were the ONLY way to reset the service warnings, and that was how Vauxhall Technicians did it too,

    Have i been told wrongly?

    Clock binnacle was removed and unplugged for an hour and a half, maybe two hours, but as i suspected made no difference whatsover.

    hoping to get on Tech-2 on friday, so we'll see what that brings

    pretty fed up with it now if i'm honest,

    bloody electronics and emission control crap, this is why i still like a dizzy and carbs! (y)

    Hehe yes and carbs make a way better noise.! I'm afraid from my experience tech2 will not reset the oil life, and that fault will not revert from being permanently 'present' to a clearable 'not present/intermittent' until the light has been cleared by that usual method.

    It has me stumped too, I'll have a rethink and see if there's another approach to look at. If there are no other codes I can only assume limp mode is literally linked with the oil life exceeded code too, as opposed to the DPF being blocked. Indeed a decent long run under load would aid the DPF do a thorough regeneration.

    Retro Rules for sure!


    However, i think you're right in the Tech-2 not being able to sort this, or at least i will be surprised if it does, at which point i'm not sure what i'm left with, and i believe very likely right that the limp mode is connected to the oil life excession error code.

    Is the fault P253F and the service reset light stored in the clock ecu/chip or the main engine ecu?

    Could the Clock chip be rewritten to the tune of 100,000 miles to next service for example? and then the P253F be cleared the normal Diag way?


    If the DPF is having an impact then i'm even more disgusted than normal with these shoddy devices. My van does hardly any town work or short runs, mainly motorway and car transport trailer work, so loaded and working, although driven economically where possible.

    They will be deleted as soon as i can sweetalk someone into removing and refitting them for me!

    Another couple of points to check is that both the doors and bonnet are closed, and the reset is attempted within one minute of either unlocking or getting in the van. Worth just making sure the accelerator reads 0% when released too.

    The P253F is a powertrain code so it'll be stored within the ECM, and the accelerator pedal and brake pedal (at least one track) connected to it too, so I'd think all the oil life data is stored within it and sent via message to the dash.

    We only ever used to have this issue with the 2.5 engines in that fleet of vans - all others were 2.0 M9R's and didn't suffer. May just be the fact that due to the 2.5 being an older engine it may be just outputting a higher soot level for these early DPF'd vans, and therefore be doing more regens. Only way you'd know if it's doing them successfully is the oil life depleting too quickly.
