Hi, i bought a 2007 citroen relay 2.2 hdi with 135,000 miles on it with the chain driven ford engine and i have nothing but problems with it since.
Its hard to start in the morning or when hot and takes around 3 tries - 1st time it starts idles lumpy then cuts out - 2nd time it starts the engine light comes on it wont rev then it dies - 3rd time it starts idles lumpy engine light comes on then goes of after a few seconds then it idles right and you are able to rev it.
When trying to start it, it fires out a load of white smoke then when running its fires out a load of black smoke.
It keeps going in and out of limp mode and i don't think the turbo is kicking in properly as it has no power at times.
In high gear and low revs it pumps out a load of black smoke.
Now and then it starts pinking/knocking.
There is also a fairly load whistle when the turbo kicks in.
Removing/ unplugging the MAF sensor does nothing to how the engine runs.
I have fixed and removed a lot of fault codes but there is 4 that keep returning which are all to do with the MAF sensor.
I have replaced a load of parts, injectors, rail pressure sensor, air/oil filter, engine oil, glow plugs/relay, egr valve, MAF sensor.
The compression is 1-360psi 2-287psi - 3-284psi - 4-347psi
I have put fresh diesel in it with wynns diesel cleaner and now it pumps out loads of white/blue smoke.
I have cleaned out the inter cooler, injectors, inlet pressure sensor.
Any ideas on what it could be or what to check would be greatly appreciated as i am out of ideas, thanks.

Re: Citroen Relay Running/Starting Problems
Can you post up your VIN - there are 3 versions of Relay and within each of those 20-30+ categories! It seems you've checked everything apart from the emissions control, but we need to know what system you have on the vehicle.

Those compression reading are on the low side!
The 2.2 are known for not being a great engine and it is not unknown for pistons to wear prematurely. You should do another compression check and do a dry and wet test to see if the compression improves.

Ok, so it's the the Ford Turbo Diesel Puma 22DT 100 CV engine, with no particulate filter - just the EGR system.
Here's the EGR valve location and underneath in wider context, in case you want to check the condition:
