Thanks all, I appreciate the comments.
Best possible reasoning I've been offered yet:
"If the exhaust wheel of the turbo has broken, the bits could've been sucked back in through the exhaust port via reversion when you shut the throttle after the bang."
I think this is somewhere near the truth. A bike engined Westfield I ran suffered a very similar fate.
Sorry to hear about this OP. Gutting.
I've had my Leon for nearly 3 years and while it's been in my ownership it's only ever had Tesco Momentum 99 in it.
Never had a problem with momentum 99.......can't be contaminated fuel
Really sorry to hear this, hope it gets resolved to your satisfaction as you really seemed to be enjoying the car. Think I would go for an entire car exchange if it were me, or money back.
im gutted to hear about your Cupra mate
to my knowledge there's no preference at the fuel terminal as to who gets what. Tesco will buy it from a supplier and they won't be the only ones to buy it from that supplier. Kingsbury is the main local distributor around here and if i filled up at the Shell garage because of the 'brand' chances are very probable that id still be using the same fuel they supplied to the local Tesco, Morrisons, Asda, Sainsburys Co-op, BP and Esso.
Pretty sure I read this somewhere ages ago, the only reason it's cheaper at supermarkets is because of their buying power.
Yes Start-Stop was working just fine and it was in use in traffic probably 2 days a week. Do you think use of the Stop-Start has something to do with the failure?
