[Tanuzi al]

Just wondering if anyone knows or had a same problem. I've got a ford transit crew cab 2988cc rwd 2016 with 80000 miles on clock. I wa driving on the motorway and noticed the turbo switching of and the (engine service now) mess come on .the van was running perfect but without the turbo not more than 55 miles pH. On way back after engine was of and bak on again the problem despaired and the van was running perfect. Soon as I reach 62 mph the same problem come back on .I've teether van on non busy road on 3rd 3000rv and the problem p hasn't come .it seems it does it when I reacy that speed with almost empty van .
Thanks in advance
