Good stuff.....are you still getting the 27BB code?

Also noticed she's producing a lot of blue smoke when idling.

Try swapping the solenoid valves around, clear the codes, give it a run and rescan.

Could the blue smoke also be caused by a dodgy o2 sensor not working or mid reporting the fuel mix?

I pulled the solenoids out a while back and changed the seals after cleaning them but I will do it again.

Swap them over to see if one is faulty, if it is, then the code will change to the intake cam.

I will but after realising the regulator has gone in the drivers window, I've had to sort that first! Loving the black adhesive on the inner part, a real test of Ines sense of humour.

Cam sensor errors can be thrown by crank sensor issues.

The crank sensor is not cheap and it seems to be one of those parts where you really do need to buy the genuine BMW one.

Ok, window regulator and motor fitted. Now back to the main event!

I am about to go out and change over the solenoids as you suggested mojojojo, in the meantime I have something else to ponder on. See attached screenshot.

I refurbed four motors the other day and left one of the sound barriers in the sun, the black sealant turned to treacle.....oh what fun I had cleaning that up! lol

Do you have the emission air pump in you engine?

 

[Zhaan]

That stuff is evil, it's like a final joke from the fitters at BMW, enjoy!

If you mean the thing that sits next to the washer water reservoir then no, there isn't anything there.

 

[Zhaan]

I've swapped the solenoids over and the same error returns within minutes.

 

[mojojojo]

I think your looking at a dodgy vanos unit then mate:frown

Regarding the missing lambda, they changed the emissions set up mid production on the N42, so wouldn't worry about the missing readings. There's no error code for lamdas is there?

Here is the full error read from today.

Ok I've changed my mind.....worry about them lambda reading:eek Looks like a dead lambda, could check connections and stuff first.
The 27EC EGS is transmission related I think and I thought that was for auto's??

 

[Zhaan]

Ok, that sounds like a plan. I was planning on jacking her up and taking a look at the sensor (he says confidently) just to make sure the wiring/connector is ok before going any further. I've read a few posts where sensor cabling has been disconnected or broken, so with a bit of luck I may be in the same boat.

If I can't see anything obvious I will hand it over to a mechanic but I have enjoyed fault finding and repairing the easier stuff like the tensioner and the window regulator and motor.

But sometimes you just have to leave it to the professionals!

I will let you know what I find.

 

[Zhaan]

Just thought I would check the possible 'dead lambda', is that the one top right reading 0.00 on my readout I supplied before?

 

[Zhaan]

Just realised the error report I sent points to the lambda after the cat. Had a look under the car tonight, disconnected the connector, cleaned it up and reconnected it, no joy.

Would I get a multi meter reading off a lambda sensor, resistance, etc.?

 

[mojojojo]

Do you have the 2 or 4 sensor system, my understanding was that the models without the secondary air emission pump only have two sensors... a control and a monitor.
If it's the 2 sensor system (like the N46) I think I was right in ignoring the bank 2 readings. Your fault codes are saying bank 1. Try getting the car up to temperature and check the live lambda data, give it some revs and see if any of the values change.
