Car rough idles with no power and no codes

    Hi all,

    I have a VW Passat 2014 1.6 TDI B7 model.

    Today I filled it up at a petrol station and then went next store to do some shopping. I was gone about 30 minutes and when I started it, I could hear it struggling to turn over. I think it even choked out and I had to restart it.

    When I pressed the accelerator, there was zero power.

    After about 10 minutes, it suddenly started turning over fine and full power returned. There were zero issues on the way home and the engine stopped a couple of times at lights with start/stop.

    I drove home about 2km and parked it up.

    It then occurred to me that I could have put petrol in instead of diesel (1/4 diesel, 3/4 petrol). I have no reason to have done this but brain malfunctions can happen and thought it was a strange coincidence that I had just filled up.

    Unfortunately, I paid cash in the petrol station and they only had records for the previous 30 minutes.
    I could ask for CCTV tomorrow but am not sure if they would bother looking at it for that.

    Anyone know if petrol could have caused the above symptoms?
    Is there anyway to easily check if I had loaded petrol instead of diesel?

    Open fuel flap and have a sniff. Normally easy enough to get the smell of petrol.

    I opened the flap and got a smell of something.
    Just not sure if it is petrol or diesel.

    I might head down to a petrol station to compare.

    Next stop, the doctors to get my head checked out

    Easy to do unfortunately, we've had many similar threads on misfueling.
    Have you arranged to have tank drained?

    I'm getting it drained this morning. It will cost 190.
    Hopefully that is the only cost.

    I'd say I have filled it up with diesel over 50 times at this stage. It seems my brain briefly malfunctioned on the 51st fill.
