2D61 - Outlet Vanos

I got this error message second time, almost owned the car for a year (literally no issues).

2D61 VANOS exhaust control Fault, Position not reached. Online stories are different, just clean the solenoid, check the seals, replace Vanos, worst case the camshaft bearings are failing etc.

I personally suspect a dirty/heavy oil as I've a service due in 4k and don't know what oil was used before. During those 2 times It always happened within 4 weeks of me topping up a 1L oil (I do buy a super duper premium), do you reckon something like an oil top up could have an effect?

2.0 worn chain throwing a timing code?

FWIW..

I would do the oil change..asap..open the filter and check for metal and/or plastic swarf…any swarf equals cam chain failure..
 
This suggests revising the DME firmware may be a solution..

Yeah, timing chain on Position of Vanos reached doesn't make any sense at all.

I would rather assume sensor/oil leaking through the sealed bearing on cam shaft, they are essentially 86k miles old.

My firmware is 2011 so it does make sense they are some software glitches.

I've got full service in 4k miles so I will update what the outcome was.
 
Update: had a solid drive today and the code came up again, this time you can hear the front of the engine. I had previous thread where I could hear metal-to-metal noise when I switched to sport.

Its defo the chain, not resetting this time, going straight to the garage on Monday :D

Update: went for a ride today and yup, exactly same, when engine is nice and cold you hear nothing (apart from HPFP), once the oil is at the temperature and I'm slowing down from motorway to a 30mph it showed up again today! Defo skipping a tooth more frequently now.

Update #3 (21/06): Happened twice today on relatively short journeys 30 min 1 way in a very hot weather. The car was in the garage last week, the ran full diagnostics and checked all vanos and valvetronic sensors, no issues. No one have idea. I had MOT last month and asked the guys to check it for any potential issues, they haven't found anything. Just a mystery at this point, It might be the software issue as someone mentioned and old oil, I think last change was around 15k miles ago so the oil is quite thin I believe causing pressure issues on vanos potentially, to be continued.
 
Figured out the mechanics are absolutely useless in most places these days, was waiting for my torque wrench to come in and thankfully both sensor are the same part number.

Took inlet and outlet sensors out, cleaned them up, cleaned the connectors (outlet connector housing was bit loose), checked the pins for damage, bend, carbonation etc. Checked the wiring housing to EMCU to make sure there is no obvious wiring issues.

All cleaned and fitted back in, I've not used the cheap E10 fuel for sometime now and it feels like changing from (Tesco value) E10 to E5 V-Power had a massive effect on overall feeling and car behaving (I normally use E5 V-power) and looked over interwebs to see that there is couple of geeky geezers who had issues with using E10.

The issue so intermittent I can't pin point it. Now having sensor swapped over and cleaned I will see what the story is.
 
Did you remove both vanos solenoids and clean them? Then re-oil and excercise with a 12vdc source. You can use car battery or any 12vdc wall wart power supply. Polarity doesn't matter, just a coil.
 
Not the solenoids, good luck trying to swap vanos solenoids and running your engine :D

Just the camshaft position sensors ;)
 
Not sure what you mean. Both vanos solenoids are identical, so you can swap them. But I didn't mention swapping... I suggested you clean, re-oil and cycle them. They pop out as easily as the two previously mentioned sensors.
