I just did my timing belt change on my 2006 TDI BRM engine and it went slow but well. I torqued everything to the correct spec but as I drove it for the first time I noticed an odd wobble at idle. Just a slight shimmy that doesn't seem rythmic but a little random. What happened? It seemed to smooth out on the first three times I drove it but that's as far as I have driven. Will it totally even out? Is it unrelated but now I noticed it where before I had not? Do I need to go back in there?
