180 bi-turbo - New engine time - DPF / EGR questions

[DXX]

Also, assuming Oil cooler retrofit is not directly connected with this issue, but a nice to have only?

Thanks

No you need an oil cooler. The 180 EGR also has a combined oil cooler and filter.

No need to remove anything with the Tafmet kit, it is well proven.

What kit is req, do you have a link please.

Bought mine direct from Tafmet here 13. EGR Diagnostic Simulator Plate for VW Transporter Multivan T5 2.0 BiTDI CFCA | eBay

For some reason they have postage set to £500 at the moment, it was free, something odd going on there!! Probably worth contacting them to see if there's another way to buy etc

Ok so basically the CFCA engine and its bolt on parts are very good except for the EGR valve. All CFCA EGR valves will fail it does not matter if it’s a D variant they can and do fail.
With this in mind if you have had a full engine replacement with absolutely everything replaced costing easily upto £14k it doesn’t make sense to leave a little ticking time bomb waiting to kill your engine again. You can go three routes now.
1) Leave to EGR in place and accept the inevitable.
2) Find a good VW engine specialist to try to retro fit a reliable EGR off of a 140 BHP VW engine.
3) Blank the EGR and fit a Non DPF exhaust pipe and have the engine remapped. Then find a tame and understanding MOT station to help you get your VW through its yearly tests.
Good luck with your quest.

Egr of 140 does not fit the 180, no rom for it in the back on the 180.

Another problem with EGR on CFCA engines when winter is cold -15 celsius degrees is that engine almost always is cold even with webasto full power work.
This means driving with CFCA without EGR is very uncomfortable.

This is the reason why i'm putting back EGR on my CFCA engine with latest revision of "D" variant.

Personally I did not heard that "D" failed.

The D cooler is no better. There's been multiple threads elsewhere of failures on the T6 with that cooler. VW did modify them/the internal coating but it's inevitable.

We don't tend to have winters as harsh as you're experiencing but mine only takes a couple of minutes longer to warm up on the coldest day. Are you sure everything else is in order? Maybe a failed thermostat or similar delaying the engine warm up?

Not sure how the EGR operates temperaturewise in CFCA engine but
T6 EU6 (AdBlue) engines close the EGR (no exhaust recirculation) when it's cold.

No solid data as I didn't log before emulator/blanking and after but anecdotally I did notice a very small difference in warm up time, but in our temps certainly nothing to worry about. However it drives much smoother from fully cold than before which suggests the EGR is part of the warm up cycle on the CFCA.

Van oil temp is 3-5 degrees cooler on a hard drive than before which has to be a good thing

In my case everything is new. Completely rebuild engine, new thermostats, pumps, everything.

This is the reason why I'm thinking to bring back EGR.
For example, last winter when it was -20 and more, on the highway while you drive 100km/h, engine was 90 degrees, when you drop speed, engine temp dropped quite fast.

Understandable. Much more severe temps than we see in the UK. Tough choice to have to make though!!
