Top issues to watch for

The most serious Peugeot 5008 problems ranked by severity. We track 7 known issues — here are the ones you need to know about first.

Dangerous
Timing chain failure (T87)
T87EP6FDT2017–202440k–100k miles
The EP6FDT 1.6 THP engine uses a timing chain system with documented premature wear of the chain and tensioner components. The wet-belt-in-oil design is particularly sensitive to oil quality and change intervals. Chain stretch occurs progressively, initially causing timing retardation and poor performance, but can lead to complete chain failure with catastrophic engine damage. This is the same fundamental issue affecting the 3008 with identical engines. Extended oil change intervals accelerate the problem significantly.
What happens if ignoredComplete timing chain failure results in piston-to-valve contact and total engine destruction requiring replacement. Repair costs typically exceed the vehicle's value. Early intervention when chain stretch is detected allows replacement before catastrophic failure, but the engine must be removed for access.

Major
Electronic parking brake failure (Mk1/T87)
Mk1, T872009–202440k–150k miles
The electronic parking brake system uses electric motors and control modules that fail at dramatically higher rates than conventional handbrakes. MOT data shows failure rates up to 77.5 times the fleet average, with the 2.0 diesel variant particularly affected. The system can fail to engage or release, and malfunction indicator lights commonly illuminate. This affects both generations as part of the shared platform design referenced in the expert database entry for 3008 commonality.
What happens if ignoredComplete parking brake failure creates safety risks on slopes and prevents legal parking. The electronic system requires specialist diagnostic equipment and genuine parts for repair. Manual release procedures exist but are complex and temporary only.
Major
DPF blockage and emissions failure (Mk1/T87)
Mk1, T87DV6TED4, RHR, DV5RD2009–202460k–150k miles
Diesel variants show elevated MOT failure rates for emissions and smoke opacity, with the 2.0 diesel showing The diesel particulate filter (DPF) blocks with soot during urban driving cycles, triggering regeneration cycles and eventually complete blockage. This is exacerbated by the PSA DPF system design which is particularly sensitive to short journey patterns common in UK urban use.
What happens if ignoredComplete DPF blockage requires professional cleaning or replacement. Cleaning costs £200-400, while replacement costs £800-1500. Continued driving with DPF warnings can damage the turbocharger and engine through excessive back-pressure. Vehicle will fail MOT emissions tests.

Minor
CV joint boot deterioration (Mk1/T87)
Mk1, T872009–202420k–100k miles
CV joint boots deteriorate at rates up to 10.7 times the fleet average, particularly affecting early mileage vehicles around 20,000-40,000 miles. The boot material appears to have durability issues specific to this model platform. Once split, the CV joint loses lubrication and ingests contaminants, leading to joint failure. This issue spans both generations and all engine variants as documented in MOT statistical evidence.
What happens if ignoredSplit boots allow water and dirt to contaminate the CV joint, leading to complete joint failure within months. Replacement of the entire driveshaft assembly is then required instead of a simple boot replacement. Early detection allows inexpensive boot replacement to prevent costly joint damage.
