I think my sons girlfriend has the highest mileage on her Aygo.
She bought a 6 months a go. 2 months ago the cat went dead and the engine it self was using a lot of oil.
I checked her car at RDW ( its overhere in Holland the same as where you guy's do your MOT)
As you can see the clock is turned BACK in 2012.
We presume that her Aygo offically has about 330.000km
My son and I changed the complete engine, gearbox and driveshaft we bought from a 2013 Citroen C1 with 57.000 on the clock. The only thing we used from the old engine was the LOOM so it will fire up .
first pic the rapport from the kilometers of her Aygo, second pic is old engine in, third pic is new complete engine on the pallet the old one out.
fourth pic is the wiringloom on the new engine.
fifth pic is new engine etc in.
sixt pic Aygo is ready to GO
Oil + oilfilter
Feulrail from another engine ( not the old engine ) cause afther the facelift the injector are squeesed. So with the injectors from the first generation the engine runs smoother
