No worries......o2 sensor?
I suspect so. My cheapo reader said 'Lean mixture bank one'. The car has 2 lambda sensors, so could be either. I cancelled the code and it has not reappeared yet, but I cannot go far until I get an MOT certificate.


Once again, that does not necessarily mean that the lambda sensor is the fault. Whats more likely is that the sensor is reporting a fault further up the system. Changing the sensor will not fix the fault.


Reading the codes is just the start of the diagnostic procedure.

Here's the disc.

probably the original GM discs ,
about the same condition that the Zafira discs where, with 9 months MOT
I chose to replace them with new because i stripped and cleaned the brakes
the pads where pretty much seized to the calipers
massive improvement of brake and handbrake once refurbished  :y


is this 2004 a late G or early H ?
I do like the simplicity of astra to work on
G or H, I don't know. Engine code is Z16XEP. You tell me.
Z16XEP is the Twinport engine fitted to late G  and early H  ;)

Late G as all H have 5 stud hubs ;)
depends on spec and engine ,1.6 came with 4 or 5 stud  :y

H is this shape H 1.6 clicky
G is this shape G aport 1.6 clicky

You are absolutely right mate. If u go back to the same place they’ll want to see the discs done. Just do them and be done.  :y
The car was tested in Warminster, miles away. New discs are ordered, so I will fit them.
On the other point, is an engine light on an automatic fail? I have read of cars passing MOT with engine lights on year after year.

can be Astra G or H as per 2004 example links above  :y

hence why I asked if it was a G or H  ;D

Not when the OBD port is below the hand brake, it's got to be a H. The G was above the fuse box.

An astra G looks very different to an astra H. A quick google would have told you straight away.

Not when the OBD port is below the hand brake, it's got to be a H. The G was above the fuse box.
astra F upto 98 obd port in fuses under wheel ish)
astra G 98 yo 2005 obd port under a cover in handbrake area
(worthy of note :x16SZR is not obd2 /no pedal test but you can flash paper clip test )
astra H 2004 port is near handbrake in console
