TSB EG029-07 and EG033-07

[Gee Spoolin]

Hey guys I've going to set up an appointment w/ the dealer for routine maintaince to be done on my '06 Avalon XLS, and I hope to have the ECM reflashed and the (somewhat) infamous poping noise problem from the steering wheel fixed.

Now I just did my homework for the TSB's relating to the ECM reflash, and I found two TSB#s: TSB EG029-07 and EG033-07. So are both TSB#s apply to the same problem? If not, which one is applicable for my Avalon?

Also, I found TSB ST002-06 which addresses the steering wheel poping noise issue. Can someone confirm this as well? BTW, what other TSB out there that can be performed on my Avy?

I'm trying to equip myself with the info I need so (hopefully) I won't get jerk around by the dealer. So if you're in the know, please share the knowledge

This is a summary. If you would like a copy of the actual TSB, use the Private Message system (left column on this page) to contact me. I also have the TSB for the revised steering column design to eliminate the "popping" noise heard/felt while turning at low speeds (and sometimes on stop/start of the vehicle).
