i cant tell form pics when rub finger nail over where the oil rings sit on that cap can you feel a ridge if so then got wear on that outer edges for sure and a sign of camshaft or and rings worn on inner edges if that makes sense, as you have 4bar oil pressure thats all good , would also suspect the oil solonoid that controls the vanos,, also if you put a 27mm spanner on the inlet camshaft can you rotate the camshaft freely from the vanos sprocket ie camshaft free wheeling if so then that vanos is faulty

when i refit them end caps i use a light swear of wellseal on the surfaces to prevent any oil pressure being bled away where joins together

I got a minimum movement on the exhaust side but I did tried a new one from tccpp and everything was the same so I put the old one back in as you can see on pictures there’s a new one on the intake side , kdo you think if I put the old one back on the inlet side will make a difference codes are on exhaust side only? I did changed chain kit twice one from tccpp and this from dnj and no difference I swapped solenoids and cam sensors to see if code would follow those but not stayed the same my vanos value on exhaust is .5 and it doesn’t move at all after adaptions cleared and relearnt

I found the specs, now on the other side is the vacuum pump supposed to pump oil into the vanos? It pumps oil when spined clock wise looking at it from this side and there’s a orifice on the bottom of the pump bore that if I blow air thru it comes out on the other end of camshaft

vac pump dont pump any thing in to vanos sprockets its just vacum it has a oil fed bearings for its own lubrication when this bearings start to wear it will slow the exhaust camshaft down and cause the tensioner to bottom out and at that point jump teeth or snap and snap top guide off,
THE VANOS SPROCKETS ARE LABELLED IN FOR INLET AND EX FOR EXHAUST MUST NOT MIX THEM UP AS DIRECTIONAL AND SIDED ,

I have these two codes come up, I swapped the vanos solenoids over codes does move, ive taken cam cover off and checked the timing, checked the power to the solenoids and not sure what to try now. anyone any ideas?
hi everyone I'm new to the site i am a 17 year Benz and BMW tech i had the same issue on my mini cooper 2010 1.6 non turbo i did the timing chain vanos gears intake and exhaust and vanos solenoids what it ended up being was a shock to me there is a non return valve under the vanos solenoid that controls oil pressure to the solenoid and to the vanos gear the spring in that non return valve fell out and was not holding pressure i got a new one for about 30 bucks put it in and my exhaust timing came right back and i was able to do a vanos adaptation and get rid of all the code car runs perfect now i hope this helps someone i have seen a lot of people looking for a fix to the codes 283D-2845

below pic its a non return valve prevents oil returning to the oil pump when not running can also lock up with crud and springs cans snap and catch them,,

Yes exactly that's what ended up fixing mine with those codes.
theres so many things that throw same sort of fault codes on these engines almost like makers have done it to make repairing them as hard as they can to get around the they were forced to allow owners to be able to read codes ,, where they would like owners not to ,, so it seems they just link as much to one code and muddy the waters make it harder thats my theory
