Help, please

Hi, bought MY first disco this morning,
old J reg (1992) i think, tdi, looks great for it's age, loads of history, runs ok except for just now... On my way to work, slowing down from about 50 on the dual carriageway loads of shakes. Really scary, but stopped after about 10 secs then seemed ok again. Need to know if i've bought a dog?

if yer slippers are chewed to fook then you most likely have bought a dog. as fer yer shakes try checking yer BJ's and stuff. a search on here should provide the required answers

Thanks, think i might be popping back to have a chat with garage on monday!
