Hi I've done a timing chain replacement on my r56 n12 all rebuilt but not running right
I've now been told to change the vanos sprockets
Can this be done without totally restripping the timing chain totally out
Can I just change the sprockets
Many thanks Dean

you can do but its a faff i use a bungy cord to hold chain up so dont fall off bottom sprocket , best off just buying another crank bolt and then be sure its retimed correctly afterwards

Ok mate thanks was hoping to just release tensioner move guide and hopefully wiggle free

Mines coming up with fault code 288d I'm just hoping it's the sprockets

 

[mike1967]

i would swap the oil solonoids see if fault moves if does then is solonoild valve, common is oil rings on camshafts pic below for part numbers

pic below must soak in engine oil other night best they go softer

Hi Mike changed vanos solenoids
Changed cam sensors
I've know changed vanos sprockets seems to have sorted it
It's running lovely now
Is the a start up procedure after you've changed the vanos sprockets

Hi Mike I didn't know about the Latch procedure
I've drove it about 20 miles now should I still do the Latch procedure you talk about
Many thanks Dean

 

[mike1967]

if its driving ok then would leave it alone , only thing I always do is reset adaptions for fuelling and vanos timing

Hi Mike thanks for getting back to me
Will I need to put in on computer for adaptations or can I do it at home

 

[mike1967]

I use snap on solus edge with 24,4 update on it that will also do vanos ,,, when you do you reset the main adaptions when engine cold then start leave on idle until fan cutc in and out you then reset vanos adaptions when oil is hot otherwise the cold thick oil can confuse it ,, sometime they take 3 of more resets on vanos adaptions to work right,, ie sometimes can make car feel a tad flat,, also after this you need to run car up road a good hour and give it some beans this will push the vanso system to its limit and same as fueling, so will learn ,,

Hi Mike thanks for getting back to me
I'm away now till Friday will do that and let you know how it goes 🤞🤞

 

[Mini mouse 17]

Hi Mike did the adaptations yesterday all seems to be OK
Is there anything else I need to be doing now I've changed all that
Also my driver's seat back rest moves slightly when you brake or accelerate any idea what that might be
Thanks for all your help 👍🏻

 

[mike1967]

might need to seat or maybe weld as cracked perhaps,

Hi mate I hope you don't think I'm a pain but when pulling away in first gear I have to give it some revs when releasing the clutch otherwise it feels like it will cut out
It ticks over at about 7 to 8 on rev counter
Just to let you know the exhaust blows near the front flexi
Do you think it might be the rocker breather that goes behind the inlet manifold
I noticed there's smoke coming up from behind engine when she's warm hope you can help mate

 

[mike1967]

if exhaust leaks around flexi and cat it will cause all kinds of running issues as air can get to down stream 02 sensor and ecu will trim fuel accordingly. so yes flexi needs fixing

 

[Mini mouse 17]

Ok thanks for that mate I'll change and see if that fixes it 👍🏻

Hi Mike I've code code 0597 coming up any idea what I need to change
Many thanks Dean

 

[mike1967]

What the P0597 code means. If a PCM (Powertrain Control Module) stores this code, it's because the engine's thermostat is experiencing an issue with the control voltage. The control circuit is most likely either open or short.
The P0597 trouble code signifies that a thermostat heater control circuit is open.

Hi Mike thanks for that I'll change thermostat housing
Also I've seen a thermostat housing adapter cable for sale on ebay should I change that has well
Many thanks Dean

 

[mike1967]

the adapter cables are only for the later engines ie n18 where the thermostat housings were different on some cars , also i would not fit anything else but genuine or febi housings , reason behind this is these engines live on a knife edge of heat and only thing that controls this in live time is thermostat and temp sensor ,, also while doing the thermo do the plastic link pipe at rear of engine to water pump,,,LAG THE END TO WATER PUMP WITH RUBBER GREASE I USE OR CAN CLIP SEAL AND LEAK,,, and i promise you if do it will be within a hour of running it for first time,,, and the 2 hours to fix it again will drive you nuts, as its best to pull the inlet manifold to get at where it pushes in to the hole behind the water pump,
