John TA Posted January 15 Share Posted January 15 My Peugeot dealer has told me that the engine valves are coked up and need a £7,500 replacement, which Peugeot will only pay 25% of the cost, as the valves are an 'upgrade'. This is despite the vehicle having an extended warranty, which the insurers will not honour a claim on it. My argument is that the valves were not fit for purpose in the first place - not least because it has only done 51,000 miles and therefore I am not prepared to pay a penny for this. Has anyone had a similar experience with Peugeot? Any advice would be greatly appreciated. Thanks. Quote Link to comment Share on other sites More sharing options...
Tracker Posted January 15 Share Posted January 15 Sorry John, I can offer you no easy solutions but if you are an AA or similar organisation member they may be able to help, possibly not, but maybe worth an ask? This kind of attitude seems to pervade European makers in general who fail to understand that a happy and satisfied customer is often the very best vfm advert that they can get. They may want to charge you £7500 but you can bet your cotton socks that it actually costs them a heck of a lot less than that because they are obsessed with compounding your misfortune in the name of profit. As the Post Office would say - you are the only one with this problem so it can't be a design fault - yeah right! Quote Link to comment Share on other sites More sharing options...
Brian Kirby Posted January 15 Share Posted January 15 This is all somewhat off topic for a motorhoming website, but it all seems wrong to me. Was this vehicle initially bought new, by you? If so, how old is it, and what is the duration of the Peugeot warranty? Is the garage a franchised Peugeot dealership? On the basis of average annual mileages, I'm guessing your vehicle is now 4 - 5 years old? Is this correct? On the question of the need to de-coke the engine, If the valves are coked, then the combustion chamber generally should also be coked. To know that, and to assess the full extent of the build-up, AFAIK, the cylinder head needs to come off. I'm assuming the garage hasn't already removed the cylinder head? Ask the garage how they know that just the valves are coked. What is their evidence for this? Third, why would Peugeot pick up any of the bill, unless there is a design/manufacturing fault that Peugeot is already aware of? And, why 25%? Goodwill gesture? If the valves are problematic, to the extent that upgraded valves are necessary to prevent engine damage from valve heads dropping, or similar, and potentially wrecking the engine, Peugeot should meet the repair cost in full under the warranty. However, this assumes that the vehicle is still under Peugeot's warranty. A quick web search does not reveal valve problems as a known issue on this model. When does/did the Peugeot warranty expire? Why was the extended warranty taken out? Is it a Peugeot warranty, or merely an insurance backed third party warranty? In either event, have you read it to see what items it covers? Maybe engine faults are excluded, or faults that are also covered under the manufacturer's warranty. Extended warranties are usually very specific as to what they cover and, more importantly, what they don't. AIso, is it still in force? Have you approached Peugeot directly for their advice on this "valve upgrade" to see if such an upgrade actually exists, and why? May be worth speaking to their technical department and explaining what you have been told. Most, if not all, manufacturers have "expert" mechanics who will visit and liaise with their franchised dealership's workshops to help resolve unusual problems. Maybe explore this option? I'm not aware of the cost implications of this, so ask before proceeding if this is offered as a possibility. 1 Quote Link to comment Share on other sites More sharing options...
colin Posted January 15 Share Posted January 15 A quick google shows several issues with Peugeot engines coking up. Quote Link to comment Share on other sites More sharing options...
onecal Posted January 15 Share Posted January 15 (edited) Hi Combustion chamber may be ok Unless ring or piston damage , It more than likely is the inlet manifold and valves are coked up which will not need head removal It will need the inlet manifold removed and valve inlet and outlet ports to be cleaned This can be done by walnut blasting and I am sure many specialists and some mobile garages mechanics may carry out same for you in your area along with EGR V/V etc' I am afraid this is common on a lot of Direct diesel Injection model engines also with the extra equipment added to reduce emissions. Crankcase ventilation also needs to be checked . Regarding your dealer , I have no idea where they arrived at that figure , just to de coke the inlet manifold and EGR and valves inlet and outlet ports ????(maybe they are pricing in a replacement inlet manifold or replacement engine ) Was the engine oil left in for long service interval? Also was the fuel quality always correct ? If piston /ring and bore damage then that's a different story It just may need more than just as you quote (engine valves are coked up and need a £7,500 replacement) Let us know how you get on Edited January 15 by onecal Quote Link to comment Share on other sites More sharing options...
Brian Kirby Posted January 16 Share Posted January 16 But even so, upgrading the valves? And then apparently agreeing to meet 25% of the (very considerable) cost under warranty? The head would have to come off to replace the valves, and I assume the replacement valves would need to be lapped in, rather then leaving them to hammer themselves in? Altogether, it just doesn't seem to gel. Quote Link to comment Share on other sites More sharing options...
onecal Posted January 16 Share Posted January 16 Hi Brian No need to remove the head or replace the valves for a decoke only , unless the engine is wrecked and that's far from a valve decoke We just walnut blast the inlet manifold and inlet and outlet ports Clean other parts as I mention in my previous post This is a common issue .I agree it's a strange one especially for the price quoted Looks like a complete engine job ???? Maybe the OP will confirm as his original post is a little strange Regards On 15/01/2024 at 11:28, John TA said: My Peugeot dealer has told me that the engine valves are coked up and need a £7,500 replacement, which Peugeot will only pay 25% of the cost, as the valves are an 'upgrade'.

Tracker Posted January 26 Share Posted January 26 Just a thought! I have found that when given bad service or poor vfm a carefully worded, factual, polite, emotion free, but clearly stating my own point of view review on Trustpilot very often gets a response - and if that response is hollow, like so many, a follow up update often serves as a gentle kick up the bum! No suppliers like bad publicity so on the basis of nothing to lose it might be worth a try? Quote Link to comment Share on other sites More sharing options...
onecal Posted January 27 Share Posted January 27 Hi Maybe as the OP's wording "valve upgrade" or decoke was not covered in his extended warranty, ? Regards 1 Quote Link to comment Share on other sites More sharing options...
