2014 Peugeot 508 2.0 BlueHDi 180 – Workshop Service & Repair Manual

Common Problems & Maintenance FAQs for Your 2014 Peugeot 508 2.0 BlueHDi 180

• Why is my 2014 Peugeot 508 2.0 BlueHDi 180 showing an "AdBlue fault" or "antipollution fault" message?

  It sounds like a common AdBlue system issue. Often, these messages appear due to crystallization in the AdBlue tank or a sensor malfunction. First, check your AdBlue level and top it up if it's low. Sometimes, driving for a bit at consistent speeds can help, as the system tries to regenerate. If the warning persists, it usually points to a faulty AdBlue tank or pump, which might need replacing. It's a good idea to get it diagnosed by a Peugeot specialist, as ignoring it can lead to reduced engine performance or even a non-start situation.

• What should I do if my Peugeot 508 2.0 BlueHDi shows a "risk of particular filter clogging" message?

  This message often indicates your Diesel Particulate Filter (DPF) might be getting clogged, even if diagnostics show it's only moderately full. Try taking your 508 for a longer drive, ideally on a motorway, keeping the engine revs above 2,000 RPM for at least 20-30 minutes. This helps the DPF regenerate and burn off accumulated soot. Also, ensure your Eolys fluid (the DPF additive) isn't low. If the problem persists after a good drive, it's best to have a mechanic check the DPF and its regeneration system.

• My 2014 Peugeot 508's infotainment screen freezes or goes blank; what can I try?

  Electrical glitches can be a nuisance! For a freezing or blank screen, a simple restart might do the trick. Try turning the car off, locking it, waiting a few minutes, then unlocking and restarting. Sometimes, these issues are resolved with a software update. If you haven't had one recently, your local Peugeot dealer might have an update that clears up these bugs. Otherwise, it could be a wiring or unit fault, which a diagnostic check would help pinpoint.

• How often should the timing belt on my 2014 Peugeot 508 2.0 BlueHDi 180 be checked or replaced?

  The timing belt is super important for your 2.0 BlueHDi engine! While official intervals can vary, many owners and mechanics suggest replacing it sooner than the factory recommendation, especially on diesel models. A common guideline is around 8 years or 75,000-80,000 miles, whichever comes first. It's usually a good idea to replace the water pump and tensioners at the same time, as they're all part of the same system and failing components can cause significant engine damage if the belt snaps.

• Why is my 2014 Peugeot 508 2.0 BlueHDi 180 automatic gearbox feeling jerky or slipping?

  If your automatic gearbox feels a bit jerky or like it's slipping, especially at lower speeds or when shifting, there are a few things to consider. Your 508 typically has the Aisin EAT6 gearbox, which is usually quite smooth. A transmission fluid change, particularly a full flush, can sometimes help if the fluid is old or contaminated. Software updates for the gearbox control unit can also address some shifting quirks. If it continues, it might indicate wear in internal components like the torque converter or solenoids, and a transmission specialist should take a look.
