    E28 520i excessive idle speed

    I’ve had the car for a few months, but apparently two or three years according to previous owner. I don’t know how the mechanic did it, it’s beyond my capabilities, but it’s worked. I’ll have to see how it performs on a cold morning..... but I can wait for that. cheers

    E28 520i excessive idle speed

    Seems to be sorted now. Took it to an ex-BMW mechanic who's solved it; he said the idle mixture was far too rich, went into the AFM and made adjustments. Tick over purring beautifully now, so hope this may help anyone having similar issues.

    E28 520i excessive idle speed

    Hi, having trouble with the idle RPM, here are the symptoms: Car starts ok, any weather, and will rev at around 800rpm, but within a minute or so the idle will increase up to 1500rpm. Then, whilst driving it's not noticeable, until the clutch is engaged or put into neutral, then the rpm can again increase up to 1500 or so. This can happen until the temp gauge sits right in the middle, at which point RPM drops to between 800-1000 (think it should be slightly lower, but I can cope with it). Anything less than middle and the RPM is excessive, almost like the auto choke isn't switching off even if the car's been running for a lengthy time. Trouble is, the temp gauge never reaches right in the middle unless I'm sitting in traffic or similar. Temp gauge generally sits just below middle. Car is a 1987 520i, any advice is welcome, Cheers.

    aftermarket water pump

    Yes, it's what I'm thinking. There's such a big difference in price between pretty much all of the aftermarket ones to the main dealer water pump. But I think main dealer it is. Cheers.

    aftermarket water pump

    Hi, I'll be getting the cam belt and water pump changed on my '87 520i shortly. Seems to be many aftermarket water pumps around and which are considerably cheaper than the oem one. I may have answered my own question of which to invest in, but does anyone have experience of these aftermarket water pumps, or oem ones for that matter? Cheers.

    520i lux spark plugs

    Hi, new to the forum. I bought a 1987 520i lux last year and will be ready to carry out my fist service; After checking a webpage for the correct plugs I purchased some NGK BP5ES ones recently which have a 0.6mm gap. I'm sure when I looked in the Haynes manual it mentioned 0.7mm gap. Will these BP5ES plugs be ok?

    Rear apron

    Sounds good. Any idea what I might be looking at for the part?

    Rear apron

    Oh right. Yes, it looks like that. Does that mean replacing isn’t an option?

    Rear apron

    Thanks Dan, not as clear cut as I thought. other than getting under the car and having a look, is there any other way of telling whether M Tech kit is fitted?
