I have a 2007 335i E92 with 96K miles on it. Lately it has been running pretty roughly on idle but it then goes away when it warms up. I don't think valve cleaning has ever been done (I'm second owner) and I got a quote from the BMW dealership for $600.

Is that too expensive?

Does anyone know of a good place that does it for cheaper in the Richmond, Virginia area?

there is a pretty good DIY on here, if you feel ballsy enough to take things apart. I did mine a few months ago, and it went pretty well. Spent about 1-2 hrs on the setup, and about 2 hrs blasting. I would do it again. Cost was around $150 for the parts.

Have a link to the DIY guide you used? Willing to take a look at it and give it a try...
