1.5 Berlingo Diesel Exhaust Smoke

[Stephen A]

Hi. New to the forum, but not new to Citroen.

This being my second Berlingo van. 2019 with 16k miles on the clock.  Has started to produce greyish smoke mainly during acceleration, but I have noticed during idle. If I accelerate hard, then a puff of black smoke. Took to a local diagnostic centre and £500 later have performed a smoke test on the manifold and turbo. No issues there or fault codes. Replaced the fuel filter and EGR valve. Apparently it was sticking. The fault has not cleared. Excess smoke is now as an advisory on the MOT. It's driven with purpose for about 150 miles/week. recent oil and filter replaced.

Many thanks in advance if you could help please

Presumably it has a DPF and if so then a dose of DPF cleaner may help.
