I've just realised there isn't a sticky thread in this section for the common problems etc of the astra G... So with this in mind, I thought it would help other people out if you could all post up problems in here - that you know for a fact are pretty common, not just any so and so problem!!

Maybe separate them into sections for example (I don't know all the engine codes so...):

GENERAL

Rear springs tend to break

PETROL ENGINES

Cambelt driven engines - water pump should be replaced at service intervals with cambelt

Z20LET

Air Flow Meters fail occasionally

Z18XE

DIESEL ENGINES

Please make this constructive as possible!!! :thumbs: :thumbs:

I think it's a great idea and I'm surprised it hasn't been done before!

The rear springs do tend to snap, but the lowered springs (SRi and GSi models) are an exception to this rule.

Also, rear disc brakes on the SRi models have a tendancy to seize up if they are Bosch calipers (Lucas calipers replaced the Bosch ones and solved the problem).

Can't think of anything else just yet.

You don't say! My model's an SRI... :shock:

Anyway will put what you said in about the calipers :thumbs:

1.7DTi:

Turbos and head gasket issues around 80-100k.
ECU sometimes burn out
Glow plugs fail leading to EML and obvious starting problems

2.0DTi:

Injection pumps fail at 60-80k if using crappy diesel (see Adsa/Morrisons, Tesco). £800 for a recon unit including fitting!
Turbos are weak, can fail at 80k
Injector seals can leak leading to starting issues
Injector spill pipes perish, also leading to starting issues
EGR problems due to clogging with soot

Pre 2003 2.2i

I read somewhere that the oil outlet for the timing chain is too small, and can become blocked - causing a snapped timing chain, and a much lighter wallet.

However, this isn't mentioned on Autodata, so I don't know. Anyone have an idea? My mechanic friend recommended that when you have the oil changed, flush it through with a load of cleaning gunk, just to be sure (Y)

@Mikehodges I'm just waiting to hear confirmation of what you said before putting it in. I personally have no idea if it is true or not!

Rear Bosch caliper seizure applies to all 1.8 16v/2.0Di 16v with ABS and all 2.0DTi 16v/2.0 16v as all these get the 264mm diameter rear disks, not just SRi.

this is true but most the engines with this trouble went into the vectra! only a couple of the early 2.2 astra's had this fault but u dont see them anymore

on the astra z18xe and the 1.6 8v the ticking noise coming from the engine cambelt area on start up (not carbon canister) seems to be a common one seen a thread on that one a few times.

I have had faults with my alarm in the past where the power sounder had to be replaced two or three times. Good idea for a thread.
