Hello From Dave (Murphy) Newby
Discussion
Hello everyone, Thanks for letting me in to Piston Heads! (I don't get pist-on-head very often)
I own a 2001 Astra 2.2 Diesel Estate. Had it for about six months with no issues, but a week ago it started idling roughly when started, along with engine and spanner warnings, the car was sluggish until I got it to run above 25-30 MPH but is getting worse every day.
Could you tell me where the EGR valve is? I have looked but cannot see it.
Any help will be much appreciated.
Thanks
Dave

Hi Dave!
Welcome to PH!
It's quite possible that EGR etc is gunked up, is it run on supermarket fuel - A tank of V-Power diesel or a shot of millers could well improve things a little. But it sounds like its barely drivable at the moment so probably needs a bit more.
Where abouts are you based? If you're local to me I'll happily come and plug in my Op-Com to read the codes for you, or pop over Astra Owners Network, or somewhere like VVOC (2.2 DTI shared with Vectra) and someone local might be able to assist you.
This link may help your out if the locations are the same as the vectra.

Hello again,
Thanks to your info, I found the EGR valve, it was badly coked up with black soot about half an inch.. I gave it a good clean, which I thought would sort out the issue, as the car started up normally, but it didn't last long, about 300 yards the revs dropped to zero. However, I took it out on a run of about 5 miles and it started to run normally, I even stopped in a lay-buy and sat there for 5 minutes and it started up and took me all the way back home without further ado.I will try again in the morning, to see if it was just a fluke.
One other thing I noticed when cleaning the EGR is that the plastic engine cover has foam underneath, it is soaked in oil deposits. The top of the EGR is actually pushed into the foam, I will try running the car tomorrow without the engine cover.
Again, thanks for helping me with this.. Cheers Rick... Dave.
Hello again, I am back again with my on-going Astra Estate idling/loss of power.
Checked the EGR valve by blowing down the tube, I could hear it opening and closing so that's fine
I took a look at all the other tube lines and connections, there was only 2 which had slight cracks (fixed)
Removed the MAF sensor in the Air intake, it is very clean and not damaged.
Not being an expert on this problem, I think this issue occurred when the weather
changed from warm to cold a couple of weeks ago. The problems disappear once the car warms up
to about 80 degrees on the gage, Is this a problem with the turbo?
Your help is much appreciated.
Cheers, Dave

Turbo problems are usually pretty easy to diagnose from either noise or oil usage/leakage.
Completely different engine but a mate had a not dissimilar problem with an older Vectra diesel which transpired to be the fuel pump (after he'd changed most everything else) - diesel being denser when colder made the symptoms more noticable when the engine AND outside temp was low.
Fault code readers are pretty cheap these days too - if you have a smartphone, all you need is a Dongle - if not you can get an all-in-one code reader for very little money (Amazon do one for <£10 IIRC?).
Just remember that fault codes don't always lead you to the problem itself - they're often knock-on problems and you need to work-out which are serious and which are just FYI things (some Peugeots log faults when drivers don't wait for glowplug lights, for example - but the code doesn't allude to that at all!!)#
p.s. don't know if you can change it - but making a post title more informative (Astra Diesel with idling problem) will attract more mechanics!

Hello Again..
Well things have got worse, I went to a shop to buy some fags etc. about 10 o'clock, got back into the car and turned the key and something in the barrel snapped (it had always been a bit loose!) the car would not start, removing the key left the dash lights flashing. I wonder now that maybe this has been the real cause of the issues I have had for the last month. I took the covers off the dash and realised that this was not going to be fixable.
So I bought a full steering wheel set on eBay (£49 with all the bits including a new Key etc.) I won't find out until the end of the week, hopefully this will remedy the problems I've had lately... Wish me LUCK!!!!
Cheers, Dave
