2007 Porsche 911 (997) problems

Common 2007 Porsche 911 (997) problems

The Porsche 911 (997) from 2007 is a popular choice among enthusiasts, but it does have some common problems that owners have reported.

• Bore Scoring: Bore scoring is a condition where the cylinder walls of the engine become damaged, leading to a loss of compression and power. This issue is more common in the M96 engine and can be a concern for potential buyers. However, it is not a widespread issue and can be detected through a borescope inspection.

• Over-revving Events: Over-revving the engine can lead to serious damage and is a concern for potential buyers. A professional inspection can detect if the engine has been over-revved, giving an indication of how hard the car has been driven and potential problems this might cause.

• Bad Service History: A bad service history can be a concern for potential buyers. It is important to inspect the service history of any used car, especially if you are concerned about bore scoring. If the car has a bad service history, it may be best to avoid it or to request a borescope inspection.

• Cracked Coil Packs: Cracked coil packs can cause a misfiring engine, which is never a pretty sight on any car. However, replacements and reinstatements are relatively inexpensive, making this a relatively easy fix.

• Faulty Alternator Cables: Faulty alternator cables can lead to a decreased battery life and run-time. Replacing it with an upgraded alternator cable is an easy fix, but routing can be a tricky task on 997s.

• Damaged Radiators: Coolant radiators and aircon condensers found in the nose of the 997 are prone to leakage. The vents are typically only washed during servicing by a specialist, so radiators in poor condition are an unfortunately common sight. Always check with the previous owner about the state of their radiator, as some may have applied simple modifications to prevent leaking.

• Rust: Rust isn't an issue on 997s, so if you see any, it's most likely a sign of a poor accident repair. Don't be too alarmed if the bumper has been resprayed though, as owners tend to do this to repair damage from stone chips.

• Uneven Tyre Wear: Tyres can wear more heavily on their inside edges, so it's important to check the tread across the entirety of the tyre. With decent replacement tyres costing about £200 each, you don’t want to be caught out.

• Engine Failure: Engine failure isn't unheard of with Gen 1 997s, although equally nor is it as common as made out on some internet forums. Warning signs include a blackened exhaust tip on the left exhausts only, as well as a ticking sound from the engine at idle. If you spot either of these things walk away as a new engine will cost in the region of £8000.

• Damaged Radiators and Air-Conditioning Condensers: All 997s can suffer from damaged radiators and air-conditioning condensers due to their location behind the front bumper where they can become blocked with debris. They cost about £600 to replace, so it’s worth checking their condition and testing the air-conditioning blows good and cold.

• Brake Disc Corrosion: Brake discs can corrode on the inside if a car isn't used regularly. This is obviously hard to spot, so again it’s worth arranging for an independent specialist to inspect the car if you’re not sure.

In conclusion, while the Porsche 911 (997) from 2007 is a popular choice among enthusiasts, it does have some common problems that owners have reported. It is important to inspect the car thoroughly and to be aware of these issues before making a purchase. However, with proper maintenance and care, these issues can be avoided or fixed, and the car can become a fantastic 911 that runs like a daily driver.
