Smoke, no power and new turbo did not fix it.

**Trippy** · 2nd July 2016, 04:05 PM

I just had a test drive with my bluetooth OBDII unit and collected some data. The boost pressure stayed at 0 PSI when accelerating.

I checked under the hood and discovered that the intercooler to manifold hose (LR066429) has a large split in the hard plastic part. I took a photo looking straight down between the engine and the radiator.

This hose was replaced less than a year ago when the problems started. Initially the hose just popped off at the hose clamp but eventually it was replaced. Could a failing turbo have caused this?

Unlikely. Bandage the hose with some good tape until you get another hose.

Is there any warranty on the hose?

If genuine then perhaps try the after-market version this time.

I am guessing the smoke is black and has always been black?

I am in absolute shock that the split wasn't picked up on first up. Unbelievable. I hope the diagnosis and subsequent fitting charges for the not required turbo were reasonable??😠😠😠

...and no a failing turbocharger can't cause this issue unless it is putting out 30+ psi of really hot air for quite some time.

The mechanic failed Turbo Diesel 101 or is there more to the story?

I'd be inclined to take the broken plastic bitsy to the nearest exhaust shop and get them to bend a replacement one up out of steel tubing.

Well, the hose was replaced last year but the lack of power got worse. If the turbo was failing we probably drove with it for over a year before replacing it last week. So the mechanic did not miss the leaking hose the first time, but it has failed again.

I will tape it up tomorrow and see if that is the only issue.

If the air is too hot, so hot that it melts the hose, does that mean there may be something wrong with the intercooler?

**Graeme** · 2nd July 2016, 08:57 PM

That's a split along the edge, not appearing to be melted but instead faulty or not up to the task in your operating environment if it was non-genuine.

Why the mechanic missed the split this time is the puzzling question, assuming that the mechanic diagnosed a faulty turbo rather than an assumption on your part after last year's failure.
