New owner

HI
Excuse my ignorance as this is my first time owning an Audi and my first posting. I own an A4 (new shape) on an 05 plate....is this the B7 or B6 chassis then?
Thanks
Johny

Hi
Thanks for the welcomes.Its the large front grill (B7 then?).TBH cant stop looking at the motor outside my house...neighbours must think im sad lol.Gave the car a good wash..no polish or wax just yet. Its Moro blue comes up really good but soon shows the dirt . Coming from a Xectra V6 CDTI SRI with 170 bhp I thought the 113 BHP 1.9 TDI would feel sluggish but suprisingly feels nippier up to about 50/60.
Been looking for the right car for ages and got what I wanted with the leather seats too and 18500 miles on an 05 seems good. Anyway I hope to pick up lots of tips n tricks off the forum.
