i have usual problems with my erg valve,cutting out when slowing down dropping the gears,approaching lights and round abouts ect.
i have read that you can use a old coke can to blank off the erg valve
i have a couple of questions on this and would be grateful for any advice.

do i remove erg valve and dispose of cut a blanking plate and use a bit of hermatite and the two original bolts to blank it of ?
also would i need to get my computer re-programmed and will this eliminate the problems i have been having with the erg valve or should i just replace the valve ?
thanks for any advice you can give me.

my car is a 1.6 eco tech zafira

the light has never came on but i thought the light would come on if it was the icv as well.i had cleaned the icv and it done no difference apart from it was more responsive .so couple of days later i cleaned the arg valve and it ran great for a couple of days then the symptoms started to come back

My wife's zafira (1.6i Club) had a similar problem. I followed the advice of someone on this forum and was able to confirm that it was the EGR valve before committing to buying a new one. Here's what I did following his advice:

I loosened the EGR valve bolts and slotted a piece of pre-cut coke-can between the valve and the manifold (scissors were strong enough to cut a suitable piece). The piece of coke-can was big enough to cover the valve opening but small enough to slot between the EGR valve mounting bolts. I re-tightened the bolts and took the car for a test drive. Voila! the problem disappeared. This confirmed to me that the EGR valve was 'stuck' open and I could confidently fork out £60 for a new one off ebay.

However, please note that blanking off the valve like this is only a short term fix. The inability of the valve to control the recirculation of exhaust gases will eventually have an adverse effect on the emissions and may damage the catalytic converter.

Hope this is useful.

Kind regards

By the way - the engine management light may not come on for some time until the ECU decides that the symptoms are a problem.

No it won't - EGR isn't a vital part of the Emissions Systems, and has no tie in with the Cat - in fact, some manufacturers are removing/permanently disabling EGR Systems in efforts to rectify faults

Quote from wikipedia under 'Exhaust Gas Recirculation'

"...In almost all cases, a disabled EGR system will cause the car to fail an emissions test, and may cause the EGR passages in the cylinder head and intake manifold to become blocked with carbon deposits, necessitating extensive engine disassembly for cleaning...."

Remove an EGR at your own risk.

Kind regards
