no issues, until i was driving home when a notification regarding the engine temperature had maxed and stopped car , wouldn’t start , eventually starting and crawling back home (was 2 mins away from home when engine cut out)

another friend with a code fault reader said the lambard sensor had failed and needed replacing, so ordered one decided the friend who fitted other parts had limited knowledge so decided best to get it all sorted by experienced professional’s who know BMW’s ,

so they had it a week and determined that the fuel pump sender part had failed so they advised new one rather than a £50 one off ebay !
they also did MOT which passed few advisory point to get sorted - the occupancy sensor !!! and some pipes ,
so pick up friday , no issues , went out for drive with friend and upon merging onto motorway car went into limp mode again , 2500 revs max 40mph (this motorway is a high bridge over manchester ship canal also) exits next junction , smoke started , people indicating I was on fire ! got out car smoke pouring out everywhere!
the DPF unit was glowing red !!! smoking like a American BBQ on 4th July!

so DPF blocked (unsure how missed in MOT emissions test ! )

but got the Fuel additive for diesels and unlocking it , possibly!

next day (sunday) took for drive on extremely easy road straight and calm not much traffic !!!

jesus the smoke !!! halted the traffic both sides and fire services nearby swoop into action again think on fire ! check over good to go ,

after the smoke clears ,

monday now get a oil pressure problem and drive carefully and immediately after a transmission alert again stop driving and sort it !

so i turn off car go do some shopping go back to car few hours later ! starts first time no limp mode , no oil or transmission notification,

but the engine warning light is now on ??

m thinking having this DPF thing removed and remapped for less hassle more BHP and fuel consumption

tuesday ! car still running fine with no notification no smoke no fire

fingers crossed

thanks again for posting apologies in delay family emergency abroad
