I had my Peugeot 308 serviced in January. The service light had been on for a couple of weeks prior to the service, but went off after it (assuming it was properly reset by the garage). It’s come on again around 6 weeks later. Is it possible the service light wasn’t reset after the service, despite it having been off for 6 weeks? Or is this a sign of another issue? I’m struggling to glean any info from the manual or Peugeot site. Has anyone had this before and got answers? Thanks in advance. ---

It’s likely that nobody in this US-based forum–including me–knows about the particular quirks of Peugeots\*, but if that light was “off” for 6 weeks, its reappearance probably means a new issue. If it hadn’t been reset when it was last serviced, it would have lit-up immediately thereafter, or very shortly afterward. \*That marque has not been sold in The US since **1991**. ---

Oh wow, sorry I didn’t realise this was a US focused forum. But thank you for the opinion regardless - I’m sure you’re right and it’s a new issue. ---

Does the display show a maintenance code indicating which service is needed? ---

Unfortunately not. This is the real problem - the documentation suggests there’s a clue to the meaning of the light via length of time it’s on in combination with flashes/noises, but it doesn’t do any of that. It just comes on and stays on, which I’m guessing is just the vanilla ‘your car needs a service’ light. Very confusing given that it’s been off for 6 weeks after the service. I’ll try again and watch like a hawk to see if there are any clues. Wish I had an OBDII to check for error codes! I don’t see why they can’t just show error codes on the dash. They have a 5" display already in there! 😆 ---

The maintenance warning is a wrench symbol, that may have been reset. The “Service” warning can illuminate for low low tire pressure, low windscreen fluid, low oil level etc. ---

> [@davidbenpark\_184307](#): > > Oh wow, sorry I didn’t realise this was a US focused forum No need to apologize! While Peugeots and Renaults are sold worldwide, both French marques have been absent from the US marketplace for decades, hence a lack of practical knowledge on this side of the pond. ---

I’ll take a closer look at this - thanks! Fingers crossed it’s the windscreen fluid level 😆 ---

**Service Warning Light** The Peugeot 308 service warning light comes on temporarily due to a minor fault. The service light stays on constantly due to a serious fault where there is no dedicated fault light. A warning message may also be displayed on the dashboard. Minor faults include: - The engine oil level is low - The screen wash level is low - The remote control key battery requires replacement - The tyre pressures are low - The electric parking brake has a minor fault - Emergency Collision Braking System fault - The soot saturation level is high for the diesel particulate filter (DPF) / particle emissions filter (PEF) on diesel vehicles. To clean or regenerate the filter, continue driving at a speed of 40 mph until the warning light goes out. ---

Modern cars tend to be designed pretty similar, irrespective of their manufacturer or country of origin, mainly b/c environmental laws are so similar throughout the world now. Many of the constraints in car design these days are due to environmental rules. ---

Thank you weekend-warrior. I topped up screen wash and topped up tyres before reading your list as I routinely do that anyway. However, the light is now gone! Unfortunately that means I don’t know which (if either) of these things was the fault, but for now, the light is gone. I don’t have: - Electric parking brake - Emergency Collision braking system - A diesel car and I also recently - Changed both key batteries - Had the engine oil topped up at service so those five can be ruled out. Thanks for the help all 👍 ---

OP, just curious, what do you mean by the phrase “66 plate” in your post’s title? ---

That is some sort of auto registration terminology that is unique to The UK. ---

VDCDriver is right. 66 plate means second half of 2016. 16 plate would be first half. ---

Sorry Volvo-v70, I said the wrong thing. I didn’t mean they topped it up, I meant to say they changed the oil. I do check the dip stick regularly and top up oil if needed. ---

If Peugeot considers a low oil level to be a “minor fault” it’s no wonder their cars are generally junk. ---
