Thread: TD5 Smoke screen

collapsing intercooler hoses.

Since it happens when you lift off the accelerator after cruising along at speed, I would be thinking about the airflow.

The turbo hoses maybe delaminating inside and blocking the airflow as you slow, thus black smoke.

Undo the hoses to turbo, starting with the intercooler to intake one at the top and take a look inside.

Edit: Damn phone interrupting my typing!

Thanks for that - is the solution to replace with LR hoses or is there something better?

LR rubber hoses are fine, but an upgrade would be to silicone ones that last longer and can hold pressure better.
Usually cost a bit more though, but rubber ones from LR can be costly too.

Thank you for your advice.

I've pulled the hoses off and the turbo to intercooler hose had a huge bubble inside almost totally blocking the duct. I guess when it heats up it stretches so much that it totally blocks the air flow and hence the motors stops.

Who is a good supplier of silicone replants?

go to the bell auto services web site, you can get them here in a week from the UK, for the initial outlay you will never have to replace them. there are lots of ppl on here running them.
