Who can solve this one (My van)

Citroen Relay HDI 2.2 ....... Last week dropped a gear to turn a corner, then no power & lots of black smoke. Still runs & starts when switched off just wont rev high. New egr valve, egr solenoid control pump, all is good for 2 happy days.
Tonight on way back from hospital visiting, same again no black smoke this time though. No dash warning lights either.

HDI engine mate, my guess is the injectors are fubar

Injector or turbo

If it's the same engine found in a 2001 Peugeot Boxer diesel then from personal experience......fuel filter
May not sound right, but I had a company one in 2003 which did exactly what your describing. It was pouring out black smoke big time.
Turned out to be the fuel filter. Dealer was able to diagnose over the phone too so must be a common problem.
Got it towed into the dealer who fitted a new filter straight away and no more black smoke or loss of power. Was back on the road 10min later.

Intake butterfly sticking or spring come off

how old is it as if it new ish and running the 2.2 hdi/ ford engine not pug engine the could need ecu resetting for egr/ download i havent worked for pug for 3 years now but we had loads of downloads and replacement egr valves when ford engine come out.
