Hi to whoever reads this :wave:

My car is just back from being repaired after a crash.... long story short, it's taken 4 weeks to repair, it's been returned today - the job is awful - door misaligned, paint finish different on all 3 panels and the wheels have drip marks on them.

Anyway, that may be the least of my worries as the garage will have to rectifiy that! :roll:

What worries me now is that the Engine light has come on and I've just done the pedal test to reveal these codes :(

Car is very limp in 1st and 2nd gear, picks up in 3rd but there is a lot of smoke coming out of her.

She's been stood in a garage for 4 weeks so does anyone think that could be the problem or should I be more concerned?

Never rains when it pours..... I'm thinking a new car may be in order :':)':)'(

Thanks for reading and any help/advice appreciated!

ps - I have searched and it looks as though it's EGR related? :shrug:

Sorry to hear about the latest saga with your car. I hate having to get a car repaired - they are never the same afterwards. Maybe my standards are just too high? Definitely give the bookshop hell! ;)

I would agree that the egr is the culprit. A blanking plate would cure the problem until you get a new valve.

Seems a bit of a coincidence that it has been in for repair and now you have issues. Guess they could have left a pipe off somewhere....

As Mike says, I think the box will just be causing the additional smoke from the back of the car.

If the car has been sat around for a period if time, and the engine only run for short periods of time to move it around the bodyshop, then the EGR valve could be stuck slightly open due to corrosion.

As I mentioned above, a quick way of proving the valve is at fault is to blank it off. If the problem goes away, it is new valve time (or just leave the plate in!).

Easy enough to fit. The EGR valve is fitted by 6 bolts. 4 into the inlet, 2 into the pipe below. As far as I know (might be wrong here), the blanking plate just replaces the gasket so it is solid instead of free flowing. So just unbolt it, whip the gasket out, swap the blanking plate into it and bolt it back up :)

I would go with this one:-

http://www.ebay.co.uk/itm/EGR-blank...CarParts_SM&hash=item1e70e8df88#ht_950wt_1186

Slightly easier to fit, and the other one you linked to has holes in it to allow a limited flow of exhaust gas through the valve.

The link above is a solid plate, so no gas can flow.

Hmmm just been told this.... 'You need the one with the hole in the middle as you are not running a remap, otherwise it will keep bringing the EML light on...' is that true? This car is starting to get on my nerves :(

A solid blanking plate will bring the light on - eventually. Even plates with holes in can bring the light on - it depends on tolerances within the engine and sensors.

If you are not worried about the light being on - get a solid plate. :)

A plate with holes in will not solve your current problem if it is caused by the EGR valve sticking.

Update.... Jamie kindly checked my codes with his OPCOM. He ran the EGR test to see if it opens ok and it did.

Took the box off just to rule that out. Took her out for a spin earlier and had a good blow out. Slighty less smoke and slightly less 'lumpy' BUT as I was a mile from home, I lost power in the lower gears (limp mode?) and the EML light has come back on.

Did the pedal test.... ECN 227956 and 019012.... does it still sound like the EGR even thought the OPCOM test said it was opening ok?

Hope it's nothing too serious.... had enough of it now :(

Anthony or anyone in the know.... appreciate a bit more advice please....

John kindly cleaned my EGR Valve 2night, it was dirty, but not too bad. EML still on though and still no power until 2500 revs :(

Any ideas?

The problem with the loss in power isn't that the egr opens, but the fact that it fails to close properly allowing exhaust gas back into the intake when it should be closed and allowing nothing through and away from the turbo, stopping it from spoiling properly.

One fixed Astra :D the EGR valve pin was getting stuck as it was clogged up and the boost sensor was clogged too. A good old clean out and I have my power back! :dance1: :dance1: :dance1:
