Renault Talisman Diesel displays preheating lamp and DPF regeneration error
(Translated from German)
Summary of the thread
A 2017 Renault Talisman Diesel is experiencing a permanently lit preheating lamp, black smoke during acceleration, cold starting issues, high fuel consumption, and a 'DPF regeneration error' in the fault memory, along with a check engine light. These symptoms suggest a potential fault with a glow plug. A similar case involved replacing a defective glow plug and cleaning the DPF, which resolved the issues. Prompt attention from a mechanic is advised to prevent further complications.

Hey, thanks for your quick reply, really helpful! Can you remember roughly what you left at the mechanic? And have you had any problems since then? Best regards!

Hey, of course I remember! The repair of the defective glow plug, which was broken due to wear, cost me a total of €560. That's not exactly cheap, but the car is now running like clockwork again. There have been no more problems since the visit to the mechanic and the glow plug fault has also been successfully rectified. Hope that reassures you a little! Let me know if you have any further questions. Greetings back!

Thanks a lot, buddy! Really helps me a lot. So a visit to the mechanic is probably due. 560 € is a lot of money, but if the car runs properly again afterwards, then it's worth it. Thanks again and stay healthy! Best regards!

Hi, I got the error "Glow plug circuit A" during the readout. What could be the reason? I also had a turbocharger failure that was supposedly repaired, but since then I have a terrible whistling sound when the turbo kicks in at 2200 rpm! I also complained about the repair and they tested it (supposedly) but found no fault! What could be the reason for the whistling? Renault Talisman Grandtour 2017, manual transmission, diesel

For the "Glow plug circuit A" error, start by checking the glow plug relay and the wiring connections to ensure they are secure and not corroded. A faulty relay or poor connection can cause this error. Regarding the whistling sound from the turbo, it could be due to a loose or damaged hose, a boost leak, or an improperly seated turbocharger. Inspect the hoses and connections for any signs of wear or looseness. If the issue persists, it might be best to have a mechanic inspect it, as a turbo issue can affect engine performance and efficiency. Please update on your progress or if you have further questions!

Hey, I had a similar problem with my 2015 Renault Mégane Diesel. A glow plug was broken due to wear, similar symptoms: preheating light came on and black smoke when accelerating. Cold starting was also difficult and fuel consumption increased. Mechanic also found 'DPF regeneration error' during fault readout. It definitely seems to be a glow plug problem. It was a serious thing, not a small thing. I had the feeling that the whole engine would soon give up the ghost. But the workshop handled it pretty smoothly. The defective glow plug was replaced and the DPF was cleaned. It took a few hours, but after that the car ran perfectly. No more black smoke, no more starting problems and consumption was back to normal. Conclusion: You are probably right in suspecting that a glow plug is defective. Don't worry too much, because it can be repaired. But don't delay too long, as this can lead to further problems in the long run. So, take it to the workshop! Hope this helps you. Have a safe journey!
