Here's an example fault on the VAUXHALL Astra (1991 - 2004)

What to look for:

Check the service book and old invoices to establish that the cam belt has been changed at the correct intervals. On most engines this is 40,000 miles or 4 years.

What it means:

If the cam belt isn't changed on time, it will fail and seriously damage the engine, costing up to £1,200 to repair. The intervals vary from engine to engine so check with a local garage.

What to do

If in any doubt about when the cam belt was changed, ensure the cam belt, rollers and tensioners are all changed before driving the car anywhere. A cam belt change should cost around £250.

  • 2 interior problems
  • 1 bodywork issues
  • 2 recalls

Here's an example fault on the VAUXHALL Astra (2004-2009)

What to look for:

Check the paperwork to see if your car has a cam belt. If it does, it must be changed on schedule. Intervals can vary depending on the engine, for example CDTI engines are either 80,000 miles and 6 years or 10 years and 100,000 miles. On the smaller petrol engines, the cam belt should be changes every 4 years or 40,000 miles; others have chains and do not need changing.

What it means:

If the cam belt and associated parts (such as water pump and tensioner) have not been changed, and the mileage is over these boundaries, the cam belt is likely to fail soon. Usually the engine has to be replaced or at least re-built after a cam belt failure.

What to do

Ensure that the cam belt is changed before the car is driven anywhere if it is coming close to its interval. Changing the belt will cost £200.

Vauxhall Astra (2009-) Fault Guide

View Vauxhall Astra (2009-) Fault Guide

We know of 13 VAUXHALL Astra (2009-) faults which our fault check guide makes it easy for you to spot and avoid.

  • 3 engine faults
  • 4 suspension wear items or faults
  • 3 interior problems
  • 1 bodywork issues
  • 2 recalls

Here's an example fault on the VAUXHALL Astra (2009-)

What to look for:

When you test drive the vehicle check for the DPF warning light on the dashboard. It comes on when the car is started and goes out soon after. If the light remains on then drive the car at a steady 50 to 60mph for 15 to 20 minutes in 3rd gear. That should allow the DPF to get hot enough to burn off the particulates clogged up inside and should make the light go off.

What it means:

If you run the car at this speed for the time specified and the DPF light goes out then the car should be fine. If this light stays on it means there is a problem with the Diesel Particulate Filter. This is a device, which removes harmful particulates from the exhaust and keeps the C02 emissions low. If the car is often driven in town, or for small journeys the DPF does not get hot enough to burn off the particulate deposits. To have the repair carried out will also necessitate replacing the oil filter and the engine oil. Be aware that cars fitted with a DPF filter are not ideal if you only do short journeys such as a small commute.

What to do

If you find this fault and the car is at a main dealer and within warranty (3 years/60,000 miles) dealer then insist that the repair is carried out as part of the deal. Otherwise the car may require a manual ‘Forced Clean’ of the DPF filter, which will cost around £90.00. If you find the engine management or DPF lights lit up on the dashboard when the car is running we would advise having the car inspected by a qualified mechanic. It can cost £1000+ to replace the DPF filter if it is left clogged for too long.
