She's Lying To Me...

    Either that or it's a late April fools.

    Jumped on the motorway this evening, set cruise to 72mph. Was in no rush.

    3 mins later, ****#$€!! check coolant level in red pops up *^#%$$, stop car.

    Ok, so I hard shoulder it, thought maybe stone had punctured my radiator, nope coolant level fine, right on the max line, right where I left it ....temp gauge at dead 90.

    Checked OBD straight away (lives in the car) to get an accurate reading and it was at 84c. So normal.

    Also scanned for faults, clean bill of health - nothing.

    After restart, light out now - rag her home, technician road test style - flat out.

    Seemed to drive like she'd been on steroids.

    Do you think a dodgy coolant level sensor could relate to performance issues?

    Does this sensor double up as a temperature sensor too? Pretty sure earlier Audi's, maybe the 8L chassis did?

    As I'm sure that would affect fuelling if the sensor was telling the computer the wrong temperature, and may explain my intermittent feelings of less grunt.

    Anyway, I can only assume the sensor in the coolant bottle has had enough of life.

    30k and 2 years isn't a great lifespan, could warranty it, but think I'll do this myself, cheap fix, probably end up with a new bottom end if the techs at Audi we're let lose on it.

    I have been getting this and like yourself checked every time it came and was plenty of coolant!

    Now it comes on every bloody time i start the car, i have not yet cleaned the prongs on the sensor but probably will do before buying a new bottle/sensor...


    Sevv, how much was the new bottle?

    Common fault surely, but 2 years is bit too soon, what grade coolant have you been using?

    Easy fix would be to scrape the pins, but that sounds a bit 'kwik-fit kwik-fix' to me.

    When it happened to my A3, I spent £25 on a new Expansion Tank and £3 on a syphon and changed it very easily.

    Do you live in a hard water area?

    Clean the sensor bars up as said and replace the coolant using distilled water, or better still pure water as used by window cleaners with the water fed pole systems. It won't fur up after that!

    I've only ever topped it up once/maybe twice from new, but with neat G13. (keeping the mixture strong for my yearly ski trip) so it's not actually seen water from my area.

    I'll order a new bottle for peace of mind.

    If it does it again, scrap yard!!

    I used a toothbrush on mine, never did it again, and 84 is too low you should be at 90 deg

    I'm at work now so can see the real cost of them. They cost the dealer £12.07+VAT. (£14.50)

    Retail at £16.77+VAT

    So will only cost me £14.50 :) and a wee bit if my time.

    So If/when it happens again it'll be having a new one.

    Part number for future reference:1K0121407A

    Thank you very much for this, part number was very helpful.

    Just paid £20.12 for mine from Cheshire Oaks Audi as I feel it's time to change my disgusting old tank.
