has anyone cleaned there egr valve on a petrol Astra h? The code came up on my mates diagnostic. I have had a look online and they look easy to clean but I haven't seen any videos or pictures about the Astra h petrol one. And also where is the location of it? On my old Astra mk4 it used to be behind the engine. I fancy having a go cleaning it myself rather than buying a new one

Yes, its easier to remove the battery and battery tray to gain access for removal, you will need some Torx sockets to remove it.

I'm not sure if I have my radio code if I remove my battery, is there a way to clean it whilst on? I've seen videos (but none on vauxhalls) where they spray it into the air intake, I was wondering if that would work as it's not very close to the egr valve

You don't need radio code with the Astra H the radio is paired with the car so when you reconnect the battery it works straight away.

You don't need your radio code if you remove the battery. You will lose the trip counter etc. and may need to relearn the electric windows.

Those sprays will help clean the pipe work etc. but you will still need to remove the worst of the carbon deposits manually. It will probably explain that on the tin. It's also recommended to change the oil and filter after using them

Tried to take it off today, removed 3 torx screws and it was still solid, I couldn't take it off, is it attached to something else? Had to take the battery and battery cradle out to make it easier to access the screws
