Can a disconnected bonnet release cable be a fail Whistle
 It can when others can't,
It will when others won't,
It goes where others don't.

Think I'll start renting out my valves and pipes for MOT time.
They've been sat in the garage for 2 years now, the previous owner of mine had removed both the pipes and valves and I managed to source valves and pipes but never got round to fitting them, has passed 2 mot's in my time with them missing.

Could rent them for a week at a time - might be time to become a Forum supporter Mr. Green

Mine just failed MOT for missing EGRs. First time it has failed an MOT in 11 years. Fortunately I still have all the parts. Can’t recall if I blanked them because of EGR failure or as prevention. Probably the latter. Will look back at my posts about 10 years ago.

I know the garage quite well and feel a bit guilty going back with the fitted but still blanked.

I have just read the excellent BAS instructions that I used when blanking 10 years back. Based upon what I have read and can recall, could I remove the blanks in the top housing, fit the pipes but not the butterfly. Then fit the bottom of the pipes but over the top of the blanking plate. I would need a fresh gasket between the blanking plate and the pipe but that would then give me a sealed EGR system with everything in place. Are the 8mm bolts used at the bottom of the pipe long enough to go through both pipe flange and blanking plate?

Hi barnie

Sorry to hear urs failed the mot

When I blanked my egrs I removed the butterfly , replaced the butterfly pin in the throttle body , then used 1.5 mm stainless steel blanks , fitting them between the engine block and egr pipes

Mine went to the dealer last year for its mot and nothing was mentioned because U can’t see the blanks

Reused existing bolts as they were long enough , reused the gasket but also used some black gasket sealer

Hope that helps Thumbs Up

U can see from the pic with the pipes fitted

All back together with blanking plates in place. May spray some dirty oil over the bottom of the pipes.
For anyone putting the pipes back, removing this bracket first makes fitting the near side pipe much easier

Bolt it back afterwards.

I’m glad I was a cheapskate 9 years ago when I blanked my egr’s and just bought the cheap kit so still have the pipes and valves in place! There would be no way I would have been able to find the pipes after 9 years of my chaos storage system!
