Hello, I would like to ask you about the problem I encountered with my 207 1.4HDI vehicle. When I go 100-110 km/h downhill or on a flat road, when I release the gas and press again after 4-5 seconds, it throws dense white smoke to the rear and stops, but it does not always. Sometimes, when I go downhill without pressing the gas, around 2700 rpm, it blows out long white smoke by itself. When I hold steady and give it throttle at 2700-3000 rpm, it blows out small white smoke. There is no oil or water loss in the vehicle. The injector said there is no problem with the injectors. I saw a few other people having the same problem, but I did not see anyone sharing a solution. Someone else on the forum had the same problem, but he could not find an answer. The extras in the vehicle: hybrid turbo, downpipes, stage 2 software, DPF-EGR cancellation, intercooler, km: 108,000

If you said it was losing water, I would say that there was a burst or a hairline crack in the EGR cooler and when the EGR is opened, it causes water to be released into the combustion chamber and therefore white smoke from the exhaust, but you said it was not losing water.

There is no water loss. EGR is cancelled both mechanically and software-wise.
