Bit of Mucking around , but not that hard
Step 1 (remove both the LH and RH front corner covers , and you will see both the inlet and outlet hose connections to the after/inter cooler .Chop up old RHS hose , coz its split anyway , and rejoin it so you stuff a water hose in the inlet side (passengers)and point the another bit/end into the bucket .I filled mine with Kero first (only a litre ) then flushed it through with water , than repeated the same with half a litre of CT18 truckwash , kept flushing to the bubbles stopped . then allow to drain till dry . Reconnect up hoses and replace corner covers . I was surprised just how much oily muck had built up in the cooler , yet the Turbo is still fine , and the engine uses virtually no oil .Its not enough oil to cause any substantial loss of flow , but the oil doesnt help in the heat dissapation work the cooler must do . !!
Just make sure you flush out your intercooler properly!!
If you don't & you have fumes left in the cooler, the car engine can run away from the fumes & possibly even go kaboom! :eek:
I've just had the same issue - hissing sound from the engine bay under load, reduced power and loads of black smoke when accelerating. I just started towing a 2000kg boat and thought I'd somehow damaged the engine. It turns out that the 8 hours of towing with the turbo always on boost caused the RHS intercooler hose to split.
I guess the engine control unit uses the combination of throttle position and RPM to determine the fuel metering rather than boost pressure or airflow.
After replacing the split hose it's all fixed and I'm very happy to engine doesn't need an overhaul at 132,000km.
(picture below of the split)
Will be looking at the hoses on mine and my work van (Vito) in the next few days. Surprised if they didn't see that during service if it is split.
I just thought that's what diesels do. lol
if the hose is OK id be cleaning the MAP sensor. Everytime my D3 has a hint of black smoke normally with full throttle at low(ish) rpm a clean of the map sensor gets rid of 99% of the smoke and restores some throttle response also.
There is a LONG thread on here somewhere of cleaning MAF sensors. Some of the examples had so much gunk on them that the cars must have driven awful
Well almost two years and about 60,000 km and the hose has gone again, same place.:o
This time I've ordered silicon hoses:D and will attempt to do it myself. The dealer charged over 300 for supply and fit last time. Full hose kit cost about 275 from MR Automotive.
