single pop during acceleration/braking??
Hi all,
Been reading these forums for a while (mostly happy owner of a 1 month old is250). Recently though I've gotten this really weird tapping sound, as if there were a body in my trunk tapping on something plastic. I checked already, no body
but that noise is really bugging me. Its a single tap/clunk when I accelerate from a stop and when I brake. If I accelerate and it pops once, it won't make that noise anymore until I stop and accelerate again. I've checked everything that is possible for me to check without ripping things apart. Anybody have this sound or know of what could possibly be causing it?

Just out of curiousity......how come everyone seems to take their car to the dealer for even the simple things like oil change?? Doesn't anyone change their own oil anymore? And isn't oil changed every 3K? How come I hear it being done at 5K? What's the difference?

yeaahh its not a nasty something is gonna blow up sound, but it just bugs the hell out of me. i talked to a service guy at the dealer and he says it might be the parking brake cable. i guess i'll have them look it over when i bring it on for my 5k.

Well....no but I don't trust dealerships either.....Although having a warranty is different considering any work to be done is free. My Toyota dealership wanted to charge me $700 to replace my O2 sensors......I don't think so....and they also said if that doesn't work I'd have to replace my CAT....another $1300.......I'm no car expert but I'm not stupid either. All over my check engine light that came on......we just replaced the check engine light fuse and it hasn't come back on yet after a week. I hate dealerships.

if i followed the dealer recommended maintenence schedule, i'd be at the dealership every 2 months. which is why i change my own oil and do my own basic maintenance, unless something really bad happens. as for oil change interval, other than the first oil change, i dont' see any difference between 3k and 5k.

Most of the new synthetic oils far outlast and outperform the old oils you may be used to. With the e90 BMW, many are waiting for at least 20k to change the oil, and the oil analysis results aren't that bad at all.
