Hey Sandy. Your low pressure is 6 bar and high 150 bar. That’s spot on. I would first look at getting rid of the Sulpherized DeNox cat fault. Low mileage cars are susceptible. There is a service function to regen this cat. My Indy mate usually puts a tank of VPower and a long run up the road (motorway) to clear it. It does cause running issues. But everything else there looks ok at a glance...
The chain guides have snapped. The chain and guides come in a set for around £100-£200 change the Exhaust vanos sensor. Clean intake vanos sensor. Replace crank position and cam position sensors and you’ll be good I swear to god. This is experience
I had a long list of faults and in the end after a lot of head scratching it turned out to be no. 1 spark plug the porcelain had a crack in it… new spark plug no more problems, I also know it’s possible the seals on the vanos solenoids can cause timing issues.
It is normal to have slag in the chain , depends on how the engine stops . There is no hydraulic tensioner btw the both camshaft , so it is normal . The timing chain most of the time fails around 150-200k kms on this engines . This engines have problematic injectors and coil plugs . The plugs needs to be pushed aditionally when you snap the coil plastic over them .
Also i have this problem.if i reset adaptation valve car is working perfectly.if i try tonstart after 15min same results.i dong know why.i have a headache with this car😢
Hey, how did you fix the code 29f2, the pressure was 445 psi then 150000 hPa, I have the same problem, I changed all the fuel parts but tell now nothing changed
@@bryanjudefernandez2195 No, @sjakkelino is right. The N43 engine does have VANOS on both camshafts. @sandy anderson is pointing at the VANOS solenoids. they act like a valve for adjusting the camshaft timing. the N43 engine also has valvetronic, which controls the amount of valve lift with an electric motor on top of the engine. You may be mistaking with the M43 engine of the first generation E46, that does not have VANOS, but a single camshaft instead. The N43 engine (E90, E91, E92) (2006-2013) does have VANOS. Great engine, will work perfect when carefully maintained. Very important is the correct spec oil and services within interval as specified by BMW.
Have you managed to find the root cause of the rough idle and engine cutting-out in the BMW N43 engine? If so would be interesting to know what the fix was?
Magic wand time Sandy , let him make the decision , could be normal between cams as no tensioner there , but might be worth taking cam cover off to make sure sprocket ok
Hi, can someone tell after how many miles should the timing chain of E90/n43 should be replaced? I just got a 2010 318i with 95k miles on the clock, and am wondering if now is the time..
I have that engine with the same engine, if you take care of your car, you will be good :-) But you have to know something more about these n53 n43 engines :))
BMW RECALL as of today my 2008 BMW e92 320i is having a new timing chain and kit fitted by BMW as its stretched causing cold start and injection issues. If you have a recall outstanding for a "Quality Enhancement" then get in done. May save you ££££s

Thanks Darren we are going to try that very procedure tomorrow thanks for your help, Sandy

How did you know ? I have now the same problem, my chain is perfectly tight but it had a little bit of play before

Thanks my friend for timing chain info u help me dodge a bullet! Cheers sandy

Hi, did you manage to resolve this??
How did you solve this problem?
for replacement you need to remove the valve cover by prying it with a screwdriver.
remove the old and install the new membrane.
close the cover.
Is the Vanos actuator causing that variability in the chain tension Sandy?
Seemingly that chain slack is normal Ian! Takes me back to ford Cortina days!!!
Where I can find next part?
Just wanted to say the two components you pointed at @ 2:21 are not the camshaft sensors, those are the VANOS solenoids
i believe the n43 does not have vanos. im not too sure tho, do correct me if im wrong, i have an e92 320ci cheer!

@@i80486dx ouh i see, my bad i didnt know my motor had vanos. i think the engine before 2003 models didnt have vanos, correct?
It could be the chain tensioner

No car was sold
Sandy, what app have you used for this please?
I use the Autel 905 and Snap on Verus Scantools cheers sandy
@@sandyande Thanks mate

Sometimes a poor quality oil filter can cause timing issues especially the o ring at the bottom of the filter housing being under sized
Thanks dermot I’ll tell him that , sandy

Interesting one my friend , that chain slack seem a bit dodgy to me ...
Seemingly that’s Norma igor!
👮🏻♀️I'm sure the top guide broke 🤭 and that's why the chain plays like a bracelet on your hand and throws a bunch of crash codes
All the gear no idea 😂

Thanks for information 😉
I think you need a diagnostic dice😉
Every day lol
Sometimes you are better off not getting involved. Hand the keys back and run
But I just can’t resist lol cheers sandy
Sandy tell him to buy a Toyota.
Fixed.
Funnily enough his wife’s got one!!! Cheers Tam sandy
Yes, poor people who can’t afford to maintain German cars should buy Toyotas
