Help...315cdi 2007 no boost or power

[merc315cdi]

Hi guys looking for some ideas what to check next.
I'm assuming my van is vacuum actuator turbo operated by the 2 black solenoids on passenger under wing.
problem happened last week, came to a junction and struggled for any boost since, I new flexi was burst on the cat prior to this happening but
I've fitted a new cat, new Bosch MAF, air filter, check all pipes for leaks etc and all looks good, cleaned egr.
Fault codes p1955, p0101, p2033 and won't clear on code reader.
starts and idles fine, runs ok just no power or boost.
any ideas help appreciated
Cheers

What code reader do you have?

D900 had it for years.... Cheap but done the job

What error message is it showing.

To have NO boost would indicate that a boosted hose may have completely come off its fitting. Sometimes not obvious. Check the hard to see ones like in and out of intercooler etc.

Hi mate,
I've checked everything regarding intake etc..This has the manual actuator not the electronic one I think but everything's good, no signs of leakage but have noticed today black smoke, I did started I cleaned egr.... That was the plan.... Never got it off or even free

Black smoke indictaes air loss so, once again, check all boosted hoses and connections.
