Hey, A couple of years back, I had a similar problem with my 1999 Volvo S60 Diesel. Must say though, I only have some experience with car issues, not a professional mechanic by any means. I noticed a decrease in fuel efficiency and the check engine light came up. Did some troubleshooting, but couldn't quite figure it out myself. Ended up taking it to my local workshop, because it seemed like a complex engine problem. The guys there did a comprehensive diagnostic test, pulled out a faulty glow plug due to wear. The whole service including labor and parts cost me about 560 Euro. But my car's been working efficiently since the fix, so I consider it thrift well spent. Could you perhaps share more info about your car? Like the mileage and the last time it had a major service or a detailed diagnostic test? Would help to narrow things down. Also, ever replaced the glow plugs yourself before? Cheers!

Hey! Thanks for sharing your experience, really helpful! About my Volvo, it's done a substantial 150240 KM on the odometer. Had a major service last year. Did it myself and did the basics like oil change, filters, belts, etc. Haven't done a detailed diagnostic test in a while now, so you might be onto something there. Replacing the glow plugs myself? Nah, haven't ventured into that territory yet. Always relied on a professional for that kind of stuff. But given the circumstance, getting my hands dirty might not be a bad idea after all. Again, I appreciate you taking time to reply. Cheers!

Hey there, Well, with that mileage on your Volvo, it doesn’t come as a surprise that some parts are due for replacement. I agree, you not doing a detailed diagnostic test for a while could potentially be the reason for not getting the fault earlier. Since you did a major service last year, makes sense that you didn't catch the glow plug problem if it wasn't acting up yet. Glow plugs can be sneaky that way, they start to fail slowly and then all of the sudden your car's performance just dips. Besides, it's completely okay if you've never replaced the glow plugs yourself. Heck, most of us are more comfortable leaving the heavy engine work to the pros. But hey, now's as good a time as any to learn, and there's plenty of guides and videos out there that can make the job easier. Just remember - doing it yourself requires an extra level of patience and care, because a misplaced wrench could mean a bigger problem, but it can also save you some money. Whatever you decide, either do it yourself or take it to your local garage, you should totally get that checked out, these symptoms point to a glow plug issue. Remember, the longer you drive with a faulty glow plug, the higher the chances of other problems piling up, risking even more expenses down the line. Hope all this is helpful, and best of luck with your Volvo woes! Drive safe!

Hello, Appreciate your words of encouragement, and also for shedding light on this evil glow plug conundrum! Ha, I see what you mean about them being sneaky. Yeah, from what you're saying it seems like high time to get the car checked, a comprehensive diagnostic test would be the right starting point. I'll probably leave the glow plug changing to the experts, don't want to be causing any more damage than what's already done, eh? Thanks again for your advice. Sounds like it worked for your Volvo and, fingers crossed, should help sort out mine as well. Stay safe and keep motoring, bud! Cheers!
