Hi,

I have just been for a drive on the motorway and the engine failure: reduced speed warning came on, since having DPF removed (gutted and welded after a DPF failure to save on cost) a few weeks ago two problems have arisen.

1: When accelerating from stand still there is a tinny rattle under the drivers seat as if something is knocking on a pipe, its quite loud.

2: Second issue is when turning left or right again from stand still there is a higher pitched noise coming from the left wheel or near the exhaust.

What should i be looking at here based on the fact that the DPF was removed. The most recent change after that was a new turbo inlet pipe which had blown off, it needed the pipe, tube and sensor from BMW (£250).

Any guidance you can give is appreciated, the mechanic said he needs to take the exhaust off, after taking off the s**t stopper?

I am due to receive a new car in a week but i need to fix this to sell it but im think i need to get it to a BMW specialist not just some garage.

Is there anything i can try/look out for.

Thanks,
