As title says i get a strange vibration/rattling at 3000rpm, it's especially noticable as it's the revs you get 45-50 in 4th and 60-65 in 5th at so it's a little annoying, coins in the centre console actually buzz the vibration is so strong then it's just gone.

1st i thought it was the CV joint as it only happenned when turning a tight left, now not so sure, troubling as i just spent half what the car is likely to be worth on selling fixing the 2 front electric windows steering rack and exhaust and will be trying to sell once i pass the NCT on it.

Anyone else ever get this in a 1.4 Octavia ?

Centre exhaust mount bracket broken? or has it been recently repaired??

The backbox was completely broken off from the rest of the system and was literally hanging from the fixings, got a local mechanic to gas weld the pipe back on so this could be it maybe.

Car needs a CV joint so might get this done along with that just before i throw it up on donedeal, noise seems to be coming from underneath me as opposed to the engine bay area

The center exhaust bracket breaks just beside the middle box. Usually you just weld them and its fine but one or two Octavia's ive seen where its been welded at a different angle or wrong and makes the car vibrate as its putting stress on the exhaust.
