EGR BYPASS for CDTi - which is the latest/best to use?

75v6 · 3rd December 2016, 20:20

Hi, been thinking of an EGR bypass kit, but on reading some of the threads, some recommend the style that puts a 2p sized coin or similar in the pipe that attaches to the side, to prevent the pipe busting etc. Is the one from DMGRs the best option?

I'd be interested to find out which is the latest/best method recommended if possible. These are some options:

Many thanks in advance.

Ive had the style matt offers on dmgrs for a couple years now and has been working fine.

Hi mate I've fitted the top one from magic parts on two cars of mine been absolutely spot on, however all said and done the ones that Matt sells come with the reassurance that he knows what he is selling and knows it works.

Best check with Matt if the ones he sells now look like the picture in his ad. Last one I used (mate had bought it) didn't have the blanked stub piece on the body, to connect the exhaust flexi to. Instead it came with a separate blanking flange. This caused me a bit of grief, though probably cause I didn't install it the way it was meant to be.

Why bother, just clean the existing egr then pull the vac pipe off and put a screw in the end of it. Total cost £0.05p.

Thanks for your info. So which method do you recommend? The blanking plate on the side of the egr or the 2p-sized 'coins' to put in the other end where the flexi hose connects to?

Cheers, Chris

My understanding is that you don't have to worry about cleaning the egr if you fit a bypass, because the exhaust gases don't gunk it up anymore correct? Also improves airflow to engine and hopefully prevent air intakes gunging up as well!? Correct me if I'm wrong of course!
Thanks

that's correct, and prevents the inlet manifold from getting clogged up with that nasty black gunk, not a very nice job to have to do. I cleaned out my manifold at the same time as fitting my bypass, 2 years later when I checked my manifold it was still clean.

Technically yes but if you clean the EGR, then take of the vac pipe and put a screw in the end of the vac pipe it in effect makes the EGR redundant and does not allow the opening of the exhaust gasses. This then does not allow exhaust gasses to mix with oil deposits and therefore does not allow gunk to form. Basically the egr remains clean and so does the manifold (if you have cleaned that out too).

Buying a bypass is simply a waste of money. The benefits you will get by straight through flow of air are negligible.

Hi Chris.
If you are going to go down the road of adding a bypass, please remember that the manifold will still need cleaning out, and the MAP sensor cleaning also once it as been removed from the manifold.

These are as good as nay if you do go ahead, you should not need the bolts or gasket, personally I would stick to cleaning out the EGR and manifold once a year, I do it twice spring and Autumn as I have spares.
