DPF issues with BMW 520d

I own a 2010 BMW 5 Series. In recent months the car has reported high oil levels after a DPF regeneration. I presume fuel is now mixing with engine oil. Is there a fix for this problem?

Also the BMW garage told me at the last service that there is a slight noise from the chain at start up and I should bring it in for a probe assessment. What's the fix for this problem?

This will start to happen increasingly as the DPF fills up with ash. Probably a good idea to have the DPF flushed out by the Ceramex process. Also, vital to change the oil and filter in these engine at least every 10,000 miles or every year, whichever comes first. There is a known problem with the timing chain tensioner and on properly BMW maintained cars BMW is fixing this FoC
