My o2 reg sport tourer been everywhere all over Europe now done 170k in it
But just this last weekend it has started to misfire when cold and a bit ripe when idle, and yer it is a 2.0
now my local Renault dealer has had it 2 days and tells me that it need a engine de-coke-/coat not sure which it is LOL, and may need new pistons, yer right they want £2500 plus £75 per hour labour for the engine
, and £2070 plus £75 per hour labour again
for the pistons and the other bit.
Now i told them not to bother and they said no problem the car is OK to drive as the problem goes away when the car warms up, and i have to think if there is a problem with the pistons surely that will not go away when the car warms up?? but as i do not know much about cars I'm not sure.
now i have spoken to a friend who is a mechanic and he thinks because the car has high mileage the Renault dealer my well just be trying to fob me off so he is going to have a look at it for me should be interesting to see what he finds.
