Evening guys, my wife has just got home to tell me the Z has an engine warning light on. :thumbsdown:

Is there anyone in the Durham area with a code reader could help me please.

Many thanks in advance

I have recovery, but the car is now at home and the recovery doesn't cover home visits unfortunately :-(
 
Push it onto the road :poke: Seriously though if it’s running ok then the chances are it’s an air leak. Check the intake boot that comes off the back of the air box- I suspect the smaller hose that braches off that will be split.
 
Doh! I know it is but didn't think that would cause it!

Anyway I've arranged for a local guy to call out today to take a look with the diagnostic thingy, at least I know what to look for.

Cheers

Sorted, the engine management light stayed on once I had fixed the leaking bung but once the guy read the fault which said lean on bank one which sounds right and cleared it the fault hasn't returned.

Job done cheers

Well I thought it was sorted, Its happened a couple of times since the original and been re set both times only to re appear.

Sometimes when it is started there is a bellow of smoke out of the exhaust; I wonder if this could be a symptom of sticky piston rings with it standing around and not being used much, therefore showing a weak mixture on bank one on the readings when its checked.

Any suggestions?
 
Crankcase ventilation? Could explain the smoke out the back. There is a CCV valve that often gets stuffed up with gunk, as does the return pipe to the sump.
 
But if this is gunged up wouldn't it blow the smoke out all the time??? not just on occasions on start up??
 
It causes oil to settle in the inlet manifold which could weep into the cylinders overnight.
 
I noticed it did it within around 2 hours of my wife getting in from Work when I re started it.

Would this be enough time for that to happen do you think?
 
It certainly leads to excess oil consumption but not usually a lean code - that's typically due to a split in the intake elbow small pipe...

Taken a look tonight and mine looks like new compared to the one you have in the image deffo no splits that's clearly not the problem .. back to square one. :cry:
 
Airflow meter / lambda sensors next then I guess - lean codes could be a few things, can you post the exact codes? . You could do with looking at live values with INPA tbh.
 
Thanks for your help, managed to get it in with someone next week with all the kit who is going to have a look for me.

will update once sorted. :thumbsup:
 
Ok had the car in with the garage yesterday and...………….

The fecking dip stick wasn't pushed home and air was leaking past it!

It must have been like that since I had it serviced last. Well that's all he could find anyway (apart from a leaking rocker cover gasket) so the code has been cleared, we'll see what happens. 8)
 
New one on me! I guess the sump is connected to the intake via the crankcase ventilation valve, but that's supposed to be non-return (i.e. one way).
 
He said he could hear the sucking noise as soon as he lifted the bonnet with the engine running when he fitted the dip stick correctly it stopped. He actually mentioned that on some cars if he takes out the dip stick when they are running the engine will stop! they are so sensitive.

Well time will tell.
