OT: debris in exhaust

335i nthehouse · 07-22-2015, 03:20 PM

Another misguided 'trust in sensors' incident.

Today when reversing into my drive, I backed up to a small pile of subsoil and went too far, when I pulled forward the tail pipe was full of subsoil, which I have cleaned out.

How bothered should I be about the chance of some small bits of debris getting into backbox?

Thanks to any of you more knowledgable guys on this

I wouldn't be very worried personally. The back box doesn't do much except act as a silencer and a bit of soil isn't going to change that.

Would not overly worry, main thing is small increase risk of dampness getting to inside of exhaust.

Just take it out for a really good blast.

Soil will dry out, flake up and be blown out
