Technical Ducato running hot and no power

[Dicknorsan]

Hi guys, my first post after reading a lot threads but none specific to my issue. I have a 2009 Ducato 2.2 D 100 multijet diesel 100 hp / 74 kW based Swift motorhome with 30000 miles on it. After a winter slumber I took it for an MoT today (successfully) with a round trip of about 15 miles. At mile 14 it suddenly lost most of its power - flat driving. It stalled on a small hill into my village but eventually limped home at about 10mph. I noted the coolant temperature reach about 75% quite quickly on start up and come down to 50% after 5 miles or so. It did the same thing on returning home. Coolant level is fine; the fan is constantly on but goes off quite quickly when the engine is switched off.; the pipes/expansion box can be held comfortably. There are no lights on the dash. I will check for obd codes tomorrow. Any thoughts anyone? Thank you in advance.

Does it have a DPF or is it too old for that?

Thank you for your suggestion - I will check.

Yes, it does have a dpf between the engine and the silencer.

There are no codes, neither live nor pending.

With the coolant fan kicking in and a raise in temperature it could be linked with a DPF regeneration although it shouldn’t noticeably affect the power when it’s trying to do one. Is it stuck in this lack of power mode now or back to normal?

Hi. A 2009 Ducato is likely to be Euro 4 emissions category and is thus unlikely to have a DPF, but you would need to check the paperwork to be sure. It will have a Catalyst canister early in the exhaust system. Catalysts just work, they don't need any regeneration or other fancy malarkey. Euro 5 and DPFs came in a little later, at about 2010.

If you reckon the coolant temperature is normal but the gauge is reading high and the fans are being activated, it's possible that the engine coolant temperature sender is faulty. These aren't too expensive or difficult to change, might be worth a try as part of the process of elimination.

If the ECU thinks the engine is overheating it may have placed it in restricted power (limp home) mode.

You’d have thought limp mode would have triggered an engine light though wouldn’t you?
