Stevey Y Posted April 25, 2021 Share Posted April 25, 2021 Hi the remap won't cause oil in the water, being as you have just about changed anything that leaks I rather suspect the garage involved has not spent a lot of time flushing the water system, I did a vauxhall Astra oil cooler for my neighbour last year during the lockdown and it took longer to flush the system than it did to do the cooler, despite our best efforts he still gets the odd bit of mayonnaise in the expansion tank but the car runs fine and has been down to North Devon and back a couple of times with no problems.

Hi NO as previously posted if the water jacket on the EGR cooler is perforated it normally pressurises the water system with exhaust gas, no oil involved, if you can post a description of what the oil in the water looks like, emulsified= white sludge or just plain black that would be very helpful.
