I had my 2.2 dCi when 9 months old, since then I've had to have replaced.
Valve's approx cost if the car had been out of warranty around £250 each one.
Outside air temperature sensor replaced. This was reading somewhat silly outside temperatures reading e.g 48 degrees C, during winter. Cost not known.
The car was out of commission for 3 X 1 day return visits to Renault to sort out problems with the way they had wired up the tow bar electrics.
: This was replaced very early on. Cost approx £2,000
The bonnet completely resprayed. In one area the lacquer had started peeling, BTW I had to fight Renault like hell to get this work done. Costs un-known.
Fortunately all of the above was covered by the warranty altho I could certainly have done without all the hassle
Both rear suspension bushes replaced. Costs approx £300 This occurred just after the warranty period had expired I don't know why, but Renault replaced these free of any charge.
All Tyrus have been replaced before 30k was on the clock. Quality 17" tyres don't come cheap
On the plus side, the toys are cool.
Very comfortable ride.
Not too bad on fuel after 2 tank refills the on board computer is saying ave consumption = 40 and a bit MPG
The car tows a caravan very well.
Sori ATM I cant think of anything else.
I'll leave you to draw your own conclusions.
