2009 Vauxhall Astra 1.7L Diesel · 7 REE

The 1.7 CDTi diesel engine in this generation of Astra is known for strong fuel economy, typically returning 50-60 mpg on a mix of motorway and town driving, which keeps fuel costs reasonable despite high annual mileage. Road tax for a diesel Astra of this age sits in a relatively low band, though diesel vehicles may face Clean Air Zone charges in cities like Birmingham, Bath, and Bristol, which is worth factoring in if the buyer lives or works in those areas. Insurance for a 2009 Astra 1.7 CDTi generally falls into group 7-8, making it relatively affordable to insure. The greater concern is maintenance: with brake pipes, discs, and suspension components all flagged across recent MOTs, expect to spend £400-£800 in the near term on braking and suspension work, plus typical annual servicing of £150-£250 for a diesel of this age. Estimated annual running costs are therefore likely to be in the region of £1,400-£1,800 once maintenance is included.

Based on the MOT history, the brake system is the single most important area to inspect: both rear brake pipes have been flagged as corroded on three separate occasions, and the front brake discs were noted as worn in November 2025, so a physical inspection of all brake lines for rust and the discs for lip wear is essential. The suspension should be examined closely, with particular attention to the front suspension arms (flagged both sides in 2025) and the rear axle swivel pins and bushes (flagged in 2024), as these components deteriorate progressively and replacement costs can be significant. The exhaust system should also be checked, given the minor exhaust gas leak noted at the rear in 2024, and a cold start should reveal any diesel-specific issues such as injector wear or EGR valve problems common to the 1.7 CDTi unit. Finally, inspect the tyres carefully (the nearside front was close to the legal limit in 2023) and check for uneven wear patterns that might indicate alignment or suspension issues beyond what the MOT has captured.
