EML on minutes after filling her up and fan is going crazy for 5-10 minutes after stopping

First EML for me and limp mode all the way home.

Must be a coincidence but I filled her up with V Power and a not long after, EML came on and I lost power.

Stopped and fan was going crazy for 5-10 minutes.

I thought I had mistakenly put E10 rather than E5 V power but I was sure it was V Power as I checked multiple times before and receipt also says V Power unleaded.

I am using Autel AP200 using Peugeot DB and have these codes. Searching around I guess I should try change all coil packs and plugs first. Any other ideas?

PO351 is coil pack circuit malfunction P1336 is cam & crank sensor out of correlation combustion cycle timing prob multiple misfires
Question is which one is dying try changing no 4 for no1 or swop out different cylinders bizarrely its no 4 that can throw up a wobbler for some reason
You could as per the recommendation & I would definitely do is change all 4 packs & plugs together because they say if one is failing the others may not be far behind & don't perform as well as they should do due to them breaking down due to the heat generated

Thanks Pedro, will try moving the coil pack to see if the error code moves as well. If I remember correctly you recommend NGK coil pack don't you? Will look for NGK plugs as well. Just need to figure out the gap for a THP200, I think it's 7 or 8mm from memory.

If it was me I would put Bosch coil packs in as I think they may have been original parts when the cars were built but there are many to choose from depends on price as for plugs NGK are my go to choice as they have good heat capabilities ie wont burn to death as some others tend to do over a long period & I have installed these in a number of cars incl my 200GT with absolutely no issues I did post a refence table on here somewhere for NGKs for the Prince engines
I can't remember the gap size but 7mm is feasible as its only a mill out so can't see any problems setting to that size

A few years ago when mine had the same issues, I took it to and indie & they replaced all coil packs & plugs. They asked if I wanted them to try to source Peugeot coils or replace them with Bosch as that’s what was fitted - the coil packs were in the car from new, so It was Bosch fitted at the factory. I had NGK plugs fitted.
Sadly, although this seemed to resolve the issue temporarily, it was only a short time later I had to have the fuel rail & HPFP replaced as the issues came back and worsened. Fortunately it was all covered by the Peugeot Platinum Warranty, so cost me nothing 😀

My thoughts too..start saving for the hpfp especially if it hasn't been replaced.

His codes relate to ignition system coil pack failure if the pump suddenly began to malfunction he would have fuel related symptoms with the classic P0087 fuel rail system pressure too high/low issue or maybe I am completely wrong?

As you mentioned Pedro I will start with coil pack and plugs and then if I get the classic P0087 then might go down the refurb route as someone people have done that and seem to be very happy with it. I am expecting that I may have to replace or refurb HPFP at some point.

Yes see how it goes after the ignition system is cleared of faults I would very surprised if its the pump as they can begin to fail intermittently whereas a coil packs function will collapse once its inner core has been overheated & damaged but only time will tell if you need a pump refurb get in touch with mike on ebay type in Mini cooper Peugeot RCZ HPF pumps & the listing will come up
let us know how you get on 👍

Moved the coil packs and problem didn't move. Coil packs are Delphi which I assumed are original as noticed a lot of parts are Delphis. I then decided to clear the faults and took it for a drive and the problem has not come back.

I have ordered new plugs and coil packs are likely to replace them as not sure when the plugs were last replaced. In theory the previous owner done that in 2019 but no record of it.

Will take the car for a longer drive to see if the issue comes back. I did find it interesting that the issue happened minutes after I filled her up. I normally just put £20 worth of fuel but this time I decided to filled her up.

When you have two cylinders or more misfiring and the codes P1336 1337 etc coming up then the fuel pump should definitely be tested, I did not have a P0087 code when my HPFP went South and the THP has I believe slightly different fault code meanings to generic codes. You may have a faulty coil I did as a result of the HPFP failing, but not all 4 and not all 4 plugs. I am putting money on your HPFP being on it's way South fast showing as a consumable part of the RCZ, luckily like DKZ I have Platinum warranty so left it with Peugeot to fix and they replaced the HPFP, fuel rail and a single coil pack. I carry a spare coil pack in the car for as and when.

P1337, P1338, P1339, P1340 etc

1. ORIGIN
Detection of combustion misfiring by the engine management ECU caused by a pressure fluctuation phenomenon in the fuel high pressure common injection rail (Frequency synchronisation between the 2 pistons of the high pressure fuel pump and the opening of 2 petrol injectors).

Problems of modern cars codes sensors and the foibles and goose chases they create......add in back street garages, non-specialist technicians and 'fitters' and it's a nightmare🤪

just as a matter of interest when you opened the fuel cap did you hear a whoosh of air escaping? I remember a similar problem to yours I was asked to look at on a fiat & I pinned it down to a vacuum problem in the fuel tanks breather system I'm not saying it could bear any relation to your EML triggering after you refueled but as all modern cars have a highly pressurized vented fuel delivery system any fault with venting (Evap valve) could cause trouble

Yes I could go along with that as the pump does play up when it is dying a death the other problem he has is ignition faults can be vary vague in relation to what is actually happening when combustion is out of sync & you could almost swear its fuel related when its the complete opposite
The easiest way for the fuel system check is through the live scanning graph on a OBD reader whilst the engine is running for the High/low fuel trims this is how I knew mine was at death's door

Used to be just air fuel spark.........and off you go:) now the systems can create huge headaches and almost work against the home spannering with their foibles and almost 'mis information/diagnosis'

My plan is not to replace the plugs and coils yet and if the codes come back then likely to get the HPFP refurbished first before replacing plugs and coil packs.

Nothing at all but just a bit suspicious that it happened just minutes after filling her up to full but could just be coincidence.

Thanks Pedro, will check if mine has this feature.

If this was case what would be solution. I will check tomorrow however I had this issue before I changed the rocker cover and well wasn't sure if it was a problem or not.

Update to this. I've not managed to drive the car that much. Since the issue occurred I probably only driven the car around 80-100 miles.

Did around 40 miles on Fri and no engine fault, however, on Sat afternoon when I started the car EML came on. Hooked up my diagnostic and P0087 was there. I was expecting to see this so now will just need to figure out when I can get the HPFP refurbished. Will go through various posts to see how easy it is to get it off as well.

Now thinking back, I did feel that the car didn't pull as hard as I remembered prior to getting the previous error codes but I could just be imagining it. Plan is get the HPFP refurbished and replaced all coils and plugs since I already bought them and was planning to replace plugs for the next service interval anyway.

Mike on ebay does them for around £160ish full refurb
