    My A4 1.8T SE has developed an interesting problem. As I coasted into a parking bay at work, pretty much full lock, clutch in, brakes on. The engine cut out. Restarted fine, then ran fine. It did it once last week in the same circumstance, and again today. Any ideas?

    Does it do it with the aircon turned off?
    There is an idle adjustment gizmo (sorry can't remember the technical term) that adjusts the idle to cope with the load of the a/c system, this could be playing up.
    Also I had this issue when my water pump was starting to seize up, as it was putting too much of a load on the engine when idling to keep it running. This was 20k miles after Audi had changed the cambelt, tensioners etc so I wasn't too chuffed that they hadn't changed the water pump and the whole job had to be done again. Suffice to say I never used a stealer again and found a good specialist who did the whole job properly for half the money Audi charged the first time.

    check your PS fluid level too. If the fluid is low it takes more force to spin the pump and it tends to cut out on full lock at idle.

    My B5 had a PS leak and did that all the time if it was low and never when it was full.

    I have had a quick look and the PS fluid is on the minimum mark. That may well be it as the car is currently locked on ECON mode due to the cold weather. I hate cars with AC in the winter, they mist up the windows as soon as the AC is turned off, so I turned mine off on a nice warm day so the pipework and evaporator could all dry out!

    What type of fluid does the Power Steering take?

    LOL

    It takes audi steering fluid only, dont use anything else or you will bugger the seals in the steering rack. It isnt dear, about £8 for a litre, from an audi or vw garage. Halfrauds dont sell it, and none of the ones they have will do. If its the green fluid like mine, then only use proper audi green ps fluid.
