05 Vx Astra 1.6 Q
« on: 18 November 2011, 23:55:36 »
I have been told that it is best to blank off the egr valve...........would any issue with this bring on the EM light on intermittently?

I have not even looked, but where do you plug in the code reader?

Master Vamps car, had Lambda issues but replacement seems not to have cured the intermittent problems, however getting info from him is a no no, he is not that way inclined, plan to pop up to the garage tomorrow and find out more detail, repairs are, in part, being paid for by RAC Warranty..... :-\ :-\

Is that the Z16XE Engine Mike?

In my Astra G, it was in the region of the handbrake lever, but I'm not too sure about the newer one ...

Sorry James, I do not know, but intend to look over the weekend so thanks, I would never have thought of looking there.. ::)
I have a New Haynes Manual but it is unopened as it is a Christmas parcel for him.... :D :D

If it is, Tech II can tell it it there isn't an EGR fitted, it doen't need blanking off then.  :y

Depends on the engine variant, sounds a little to late to me for the EGR to be disabled.

And blanking it will bring the ecu light on.

Diag plug is below the handbrake but codes can be read using the pedal trick (will come up in the mileage display).

As we all know, a lambda fault code does not mean the sensor is at fault......it could (and often is) other issues (hence sensor was probably incorrectly replaced).

Is it? :-\ I thought SWMBO was the same engine code, but it was, as you suggest, a little older than 05 ie 52 plate. It's error codes were flashed up in a similar way to the Omega.  :y

Both Lambda sensors have now been changed, by different garages, first being an Auto electrician.
Been informed that the light came on again today, same code which has been cleared and stayed off at the moment.

Apparently if it comes on again the second garage, our usual independent, is going to take the car for a run and take it to the auto electrician to see if between them they can sort it..... ::) ::) ::)

If there is not point or it is too late? to bland the egr any other ideas?    His old sub £500 Citroen Saxo cost nothing in 18 months.... ::) ::) ::)

Your biggest issue is an incompitent idiot doing the diag!

I have said to many times that a lambda fault code is all to often a symptom and not a cause.

Could they not run live data? With my lamba you could watch live data to see if it was actually switching....

Nine times out of ten a lambda fault is down to an air measurement issue......the ECU adjusts until reaching an end stop and then reports 'lambda out of range' or similar..........and its a case of looking at and being able to understand live data and correction values (e.g. block learn) to get a real fault diag.

Ok Local independent took the car to well respected auto electrician and still no luck, fault code is Lambda sensor, he has been told that the car will need to be in the garage for a couple of days while they trace back from each lambda sensor, surly this can not be right?

What do yo mean by live data? and on what equipment is this done, I am wondering if we should take it to a Main Dealer, I mean an Astra, supposed to be cheap and cheerful...... ::) ::) ::)

OK getting desperate now, he is talking of px ing it, losing £800 at least, if they do not test drive it ::) ::) and he still owes me £2k so if he takes on hp he is going to stuff himself which I have advised against...
I have told him to get the EGR valve blanked off and the ECU set to ignore this....

Any other suggestions or is it into a Vx garage at my expense.... ::) ::) ::)

Or anyone who can fix it and he can come to you.... :y

Local trusted garage and highly rated auto electrics are stuck, and now want to start with replacing parts, with no end to it till fixed..... :-X

It needs diagnosing with proper live data... If all else fails I'd suggest talking very nicely to Mark ;)

Trusted they may be but clearly, compitent they are not.

There is very little that goes wrong on these and as already said, it needs live data checking to monitor the engine parameters.

A lambda fault code is not a 'lambda is faulty statement', its simply a case of the ECU has spotted that it is out of range and this can be due to a few things.

If you could get it to me I would gladly look at it.
