Opel: the people's car that refuses to fade into history
Opel is one of those brands that is simply everywhere. The Astra has been among the best-selling cars for years, the Corsa is a classic for young drivers and city use, and the Insignia offered space and equipment at an affordable price. Even after the change of ownership (from General Motors to the PSA/Stellantis group), the older Opel models still dominate the road.
An advantage of Opel is that parts are generally more accessible than for German premium brands, and the supply of used parts is large because the parc is large too. On the other hand, Opel has some well-known weak points that crop up on almost every example, so demand for those specific parts never lets up.
The most sought-after used parts for the three most popular Opel models - the Astra (H and J generations), the Corsa (D and E) and the Insignia A - follow below. With concrete prices, buying tips and notes on parts compatibility.
Opel Astra H (2004-2010): the workhorse that lasts
The Astra H is probably the most common Opel on local roads. Sturdy build, dependable engines (especially the 1.7 CDTI) and affordable prices made it a favourite. But after 15+ years, parts wear out and need replacing.
Common faults and sought-after parts
Dual mass flywheel (1.7 CDTI and 1.9 CDTI): This is probably the most common and most expensive repair on a diesel Astra H. The dual mass flywheel wears out with mileage and once it starts knocking, replacement is unavoidable. A new flywheel with a clutch kit costs 400-600 EUR, while a used flywheel in solid shape goes for 80-150 EUR. Caution: with a used flywheel it is hard to estimate the remaining life, so many owners prefer new anyway.
EGR valve (1.7 CDTI Z17DTH and A17DTJ): EGR valve clogging is almost unavoidable on these engines. Symptoms are loss of power, black smoke and a check engine light. Used EGR valve 25-50 EUR, cleaning the existing one 30-50 EUR.
Climate control module: The electronic AC module on the Astra H tends to fail, usually losing response to buttons or display. Used 25-50 EUR.
Front suspension arms: Wear out on local roads, especially the lower ball joints. Used set of arms 30-60 EUR.
Window regulators: Especially on the five-door models, the rear regulators tend to fail. Used mechanism 20-40 EUR.
Tail lights (estate version): Water ingress into the tail lights is a known issue on the Astra H estate. Used tail light 15-30 EUR.
Steering wheel with controls: The wheel buttons stop working. Used wheel with working controls 30-60 EUR.
Turbo hoses: The rubber hoses from the turbo to the intercooler crack with age. Used 10-20 EUR, but many prefer new since they are cheap.
Opel Astra J (2009-2015): more modern, but not trouble-free
The Astra J was a big step forward in design and quality, but it brought in some new issues, mainly tied to more complex electronics and new engines.
Common faults and sought-after parts
Turbocharger (1.7 CDTI A17DTS/A17DTE): The turbo on the newer 1.7 CDTI engines wears out, especially the turbo actuator. Used turbo 100-200 EUR, the actuator alone 40-80 EUR.
Injectors (1.7 CDTI and 2.0 CDTI): Denso injectors on these engines are precise but pricey when they fail. Used injector 40-80 EUR each, new 150-300 EUR.
DPF filter: DPF clogging is a common issue on all diesels in this generation. Used DPF 80-150 EUR, cleaning the existing one 80-120 EUR.
Navi 900/Intellilink: Opel's infotainment tends to freeze or stop working. Used system 60-120 EUR.
Front bumper: Used 40-80 EUR.
Xenon headlights: If the car has xenon lights, replacing a ballast or bulb can be expensive. Used complete headlight with ballast 60-120 EUR.
AC compressor: Used 50-100 EUR.
Water pump (especially 1.4 Turbo petrol): The water pump on the 1.4 Turbo petrol tends to leak. Used 20-40 EUR.
Opel Corsa D (2006-2014): small car, small costs
The Corsa D is the perfect city car: small, nimble, economical and relatively dependable. Parts are cheap even when new, and used are cheaper still.
Common faults and sought-after parts
Timing chain (1.2 and 1.4 petrol): The small petrol engines in the Corsa D have a chain that stretches with mileage. Symptoms are rattling on cold start. Replacement kit (chain, tensioner, guides) used 30-60 EUR, new 60-120 EUR.
Ignition coil (petrol engines): Coils wear out and cause the engine to misfire and lose power. Used coil 10-20 EUR.
Thermostat: The thermostat on the Corsa D can stick open, so the engine never reaches operating temperature. Used 10-20 EUR.
Front bumper: Small and cheap. Used 20-40 EUR.
Mirrors: The electric mirrors tend to stop working. Used 20-35 EUR.
Seats (driver's): The fabric on the driver's seat wears out quickly. A used seat in better shape 30-60 EUR.
Opel Corsa E (2014-2019): modern looks, familiar issues
The Corsa E is more modern and better equipped than the D, but some issues remained and new ones appeared:
- Turbocharger (1.0 Turbo petrol): The three-cylinder turbo engine is efficient but the turbo wears out. Used 80-150 EUR.
- AdBlue system (1.3 CDTI): The pump and sensors for AdBlue tend to fail. Used pump 40-80 EUR.
- Touchscreen display (IntelliLink): Used 40-80 EUR.
- Front headlight (LED daytime light): When the LED strip burns out, you need the whole headlight. Used 40-80 EUR.
- Brake discs: Small discs wear out quicker. Used pair in good shape 15-30 EUR.
Opel Insignia A (2008-2017): big car, bigger parts, bigger prices
The Insignia is Opel's answer to the Passat and Mondeo. Spacious, comfortable and reasonably equipped, the Insignia was a popular choice for families and company users. Parts are more expensive than for the Astra or Corsa because the car is simply bigger and more complex.
Common faults and sought-after parts
Dual mass flywheel (2.0 CDTI): Same issue as on the Astra, but with a bigger engine and a pricier part. Used flywheel 100-200 EUR.
Turbocharger (2.0 CDTI A20DTH/A20DT): Used turbo 120-250 EUR.
EGR cooler (2.0 CDTI): The EGR cooler can leak coolant. Used 40-80 EUR.
Electronic parking brake: The electronic parking brake module. Used 50-100 EUR.
Bi-xenon headlights with AFL (Adaptive Forward Lighting): Complex and pricey headlights. Used headlight with AFL 100-200 EUR, new 400-800 EUR.
Navi 900/CD 500: The navigation system. Used 50-120 EUR.
Shock absorbers (FlexRide system): If the Insignia has FlexRide adaptive suspension, the shocks are much pricier. Used adaptive shock 60-120 EUR each.
Front bumper (OPC Line): The OPC Line or GS Line bumper is sought-after for a styling upgrade. Used 60-120 EUR.
Rear springs (estate): On the estate, the rear springs wear out faster due to load. Used 15-30 EUR each.
GM platform: shared parts across Opel models
Opel models under GM ownership share many components, especially engines and gearboxes. Here are the most important links:
- 1.7 CDTI engine (Z17DTH, A17DTJ, A17DTS): Used in the Astra H, Astra J, Corsa D, Meriva B, Zafira B. Turbo, injectors, high-pressure pump, mostly the same or very similar.
- 1.9 CDTI engine (Z19DTH, Z19DT): Astra H, Zafira B, Vectra C, Signum. Parts are interchangeable.
- 2.0 CDTI engine (A20DTH, A20DT, A20DTJ): Insignia, Astra J, Zafira C. The newer diesel generation with shared components.
- 1.4 Turbo petrol (A14NET, A14NEL): Astra J, Insignia, Mokka, Meriva B. The turbo system is identical.
- M32 manual gearbox: A six-speed manual used in the Astra H, Astra J, Zafira B, Insignia. Known for a bearing issue, but parts are interchangeable.
That interchangeability is great news for used parts buyers because if you cannot find a part from an Astra H, the same part from a Zafira B or Vectra C will likely fit.
M32 gearbox: a special case
It is worth a dedicated mention because the M32 six-speed manual is one of the most troublesome parts on Opels of this era. The known issue is wear in the sixth gear bearings, which causes noise and eventually difficulty selecting gears.
A used M32 gearbox goes for 200-400 EUR, but the catch is that a used one can have the same bearing issue. A better option is often rebuilding the existing gearbox with new bearings (100-200 EUR in parts plus labour). Or buying a used gearbox with confirmation that the bearings have been replaced.
Some specialist workshops offer M32 bearing replacement kits that include better-quality aftermarket bearings that last longer than the originals. That is the best long-term fix for this known issue.
Where to buy used Opel parts?
Opel parts are widely available because the brand is hugely popular:
Scrapyards: Opel models are among the most common at yards. For body panels and interior, local yards are the first port of call. Prices are usually lowest at yards because supply is large.
Online marketplaces: eBay.de has a huge selection of Opel parts. For specific parts like AFL headlights or FlexRide shocks, online is often the only channel where you will find the real thing.
Opel community: Facebook groups dedicated to Opel models locally are active and parts are regularly offered for sale. Prices are usually lowest when buying directly from enthusiasts.
PoDi: For a quick and easy way to find used Opel parts, send a request on PoDi. Describe the part you need, specify the model and year, and wait for offers. For Opel, offers usually arrive quickly because supply is large.
Tips for buying Opel parts
- Check the engine code before buying. Opel uses different engines for the same model, and parts are not always compatible. The engine code (Z17DTH, A17DTS, and so on) is the key piece of info for finding the right part.
- For the M32 gearbox, ask about bearings. If you are buying a used M32 gearbox, ask the seller whether the bearings have been replaced. If not, factor the cost of replacement into the total price.
- Use GM cross-reference. Opel parts sometimes carry GM (General Motors) or Vauxhall labels. The same part can be cheaper under the GM label on the international market.
- For headlights, check the type. The gap between halogen, xenon and AFL headlights is large in both price and function. Check which type your car has before ordering.
- Plastic interior parts. Opel interiors use a lot of plastic that wears out. Used interior parts are extremely cheap and easy to swap, so an interior upgrade with used parts is a good-value option.
Opel: a solid car, a solid used parts market
Opel is a brand that offers solid cars at affordable prices, and used parts make running them even more affordable. Whether you drive an Astra H that has served loyally for 15+ years, a modern Astra J, a city Corsa or a spacious Insignia, the used parts market has everything you need.
The biggest advantage is the shared platform and parts across models, which means a large supply and competitive prices. And with platforms like PoDi, finding the right part is quick and easy. Send a request and see for yourself how much you can save on used Opel parts.
