Sluggish engine after lock down

Have barely used our van (Citroen Relay 2007) since lock down so went for a day out yesterday. For first couple of miles van lacked power and seemed to be giving out more black smoke than usual when accelerating. Did seem to improve after a couple of miles and on way home drove 12 miles or so in a lower gear to get the revs up to make sure the engine was nice and hot. Still getting black smoke on hard acceleration (can't remember if that used to happen as I generally am light on the throttle). Filled up with diesel before the lock down so fuel may have deteriorated. Intend to check air filter, if it is easy to get at. Is it worth adding one of those additives which claim to clean injectors, EGR valves etc?

It won't be fuel deterioration in the time scale.

A common problem to give black smoke on acceleration is either a faulty egr valve or a split/hole/loose hose clamp in the turbocharger pipework or intercooler. The most likely is the egr valve. Cleaning or the magic additives won't work, it will need to be replaced. Since the the 2.2 engine is the same as used in the Ford Transit aftermarket egr valves are not very expensive.

It could also be rodents nesting in your air intake, assuming it is similar to that on Fiat derivatives, as they suffer also.

You will need to remove all the ducting up to and including the air filter element to check properly.

Black smoke is typically a sign of over fuelling or lack of air so very possible.
