So daughter has a 2006 (56 plate UK) CRV diesel.

Recently goes into limp home mode quite often (no hills, no climb, no load). Quite sluggish when accelerating like it takes a split second to decide to get up and go. She has had the car about 3 months and when first bought was really nippy and responsive, not so now.

In addition she is getting 15 - 20 mpg at best and there seems to be an abundance of black smoke from the exhaust when accelerating.

Just in the process of taking to the local garage but thought I'd ask if anyone has any ideas or thoughts before we cough up the proverbial arm and leg.

You really need the fault codes from the ECM – Below is a simple diagnostics regarding the black smoke.
Black Smoke
This is due to a air to fuel ratio imbalance, either the fuel system is delivering too much fuel into the engine or there is not enough clean air (oxygen ) a few things to look for:
• Faulty injectors (injectors need attention at about 100.000 to 120 000 miles)
• Faulty injector pump
• Dirty air cleaner
• Turbocharger or intercooler faulty
• Problems within cylinder head, valves clogged up due to faulty EGR (exhaust gas recycling unit)

First thing to look at if you get black smoke and loss of power is Boost Hose connections and the hoses for splits/holes, then the Intercooler and more expensive things...

99% of the time this will be the cause of power loss and black smoke... Usually you can hear a fairly loud hiss or even what appears to be amplified engine noise if the complete hose has come off.

Usually a 7mm socket or a flat blade screwdriver will be all you need to rectify this.
