Just so long as you learn that there are always stupid questions. Don't let anyone tell you otherwise. Ze turbo has nicht kontrol over ze fuel pump. The ECU takes care of TC and will have various options for reducing power, reducing fuel being one of them.[/QUOTE] I think I did mention the TC so the question wasn't that daft ZE NI WATZ I MENZ My tyres are also fine they get me from A to B fine 99.9% of the time with no issues. Again I asked a simple question which was probably that simple it was stupid as anyone suffered with engine output drop out as I've never experienced this issue before with other cars I've owned And the answers I've received are from Experts in mechanics and professors in Rubber technology and also people who think they are Sébastien Ogier (Rally Driver if you didn't know but I will not belittle you for not knowing ) and could drive to the North pole without any issues. And car salesman trying to sell me a Fiesta !!!!! But after all the responses I've made my own conclusion to switch the traction control off !!!! And not to spend £400 on winter tyres for the 0.1% I might need them and have never required them for the last 35yrs. Perhaps people on this site would like to add value or positive answers instead of nit picking peoples questions no matter how daft they might look !!!!! Is this not what the site is for !!!!
