Will coding out the EGR prevent the dreaded cooler problem?

Soul_Glo · 01-12-2019, 07:48 AM

Please spare me the lecture on the environment.

Rather than a replacement EGR if it were to be coded out and blanked... would that resolve the matter? Or would the cooler still be functioning in some capacity?

Thanks

No, the problem is it physically cracks internally and leaks coolant.

Bugger. You would think if the EGR is not in use the cooler wouldn't be active either.

Possibly without hot exhaust gasses passing through the EGR it would be less likely to crack ?

The EGR can be coded to be fully closed all the time, and it may be possible to install a bypass to re-route the coolant circuit for the cooler. It would definitely be a warranty-affecting issue though.

Avon Tuning took care of Darth Vaders remap. Does anyone keep in touch with him? I wonder if he had the cooler bypassed when he had his EGR coded out.

What’s the issue with replacing and keeping the cooler ? Not particularly expensive ( subjective of course ) and 30 min diy to change

It's not the issue of replacement per se. It's the fact that if it leaks it is a fire risk. Bugs the hell out of me that it could happen unknowingly.

Water leak causes a fire risk ?

Dude have you followed anything on here about the EGR cooler fire risk? It's not water. It's coolant. It's also flammable. Massive recall happening. National shortage of parts.

Apologies, I do appreciate coolant has a flashpoint, Sytner have a 2 month back log because of recalls. I’ve changed the cooler myself on the 330d and was of the opinion it looked like a poorly engineered afterthought, the coolant flow through it is an open circuit and the seal between the cooler and block is a push fit o ring so to eliminate any possibility of coolant leak would require considerable re engineering so although coding out the cooler egr would reduce the risk don’t think it would eliminate the risk, also Felt the cooler cracking was due to metal fatigue so just have to accept the part needs replacing at intervals
