2015 Vauxhall Insignia ecoFLEX Tech Line 1.6 CDTi
Summary:
Economical
Faults:
Glow plugs needed replaced - expensive common issue on ecoFLEX diesels but worth it if keeping the car long term.
Bit heavy on tyres, check the alignment and rear suspension bushes for wear, I had to replace a relatively new set of tyres due to excessive wear on inside edges.
Everything else was just wear and tear expected of age and miles. Be aware the 1.6 CDTi requires the engine out if the timing chain needs done - thankfully mines is silent due to being looked after very well with early and frequent oil changes; walk away from cars with noisy chains.
General Comments:
2015 silver diesel Insignia - a very good looking and economical car. You can find these for a nice price now used, it is the ideal all round car.
"Tech Line" spec is mid range, the car has all the electrics expected of a 2015 car. Seats are very comfortable. The car is pleasant to drive. Bit of a blind spot when reversing, but otherwise everything is as easy as any modern car to navigate. The dash is laid out well and intuitive to use. Radio sound quality is surprisingly upmarket for a Vauxhall, deep and rich bass quality sound, better than many systems in more premium cars!
1.6 CDTi I decided to go for for maximum economy. It is not as powerful as the bigger 2.0 diesels but I wouldn't exactly call it slow - it moves quick enough when I need to. And more importantly it does a genuine 55 mpg or more without trying. Vauxhall's claim of 70 mpg on average is a bit of a fantasy however. But I dare say 60 mpg + is possible if you cruise on the motorways for many miles, myself I mostly do short / medium journeys these days on country roads and occasionally get stuck in the city. Not where this car shines, it is far more suited to someone who does an annual high mileage to get the best from it. A long firm drive now and then is also required to keep the DPF clear.
Still, whatever your needs I have found this car does it all. Comfortable, spacious and economical with low running costs/cheap tax and insurance.
Would you buy another car from this manufacturer? Yes

The tensioner is worth changing early on the 1.6 CDTi chain driven engine. It's a cheaper job than the full chain, and with regular oil changes, should make the chain last 100K miles + easily.
