fuel pump fails in current production

First of all, the south of France does get hot in the summer..... in this day and age, most countries experience severe hot weather.
.
that would explain why there are a large number of fp failures in France too..
but there is also more heat soak stress when commuting in a hot climate than racing through the French countryside in August.
I have had the top trim strip removed for a while because it dropped the temp around the battery from 65c in hot weather, in traffic to only 5-10c over ambient. But it is unsightly.

I’d like to chime in with my own take on this.

An, IMO, excellent, logically thought through, take on the issue. Thank you.…
Here’s hoping that the fundamental issue is indeed solved with the latest pump, and that it gets fitted to all cars in need of it ASAP.

No it really wouldn’t! It would just show that there are more Alpines that get used in the nice weather in the south of France than there are in, say, Anglesey or the Isle Of Wight!
what I am saying isa) the car is rear engined with a challenging shape for air intakes
b) it was likely heat tested in France
c) Europe has had a lot of heat waves since it was designed
d) tokyo and australia, two export markets with long hot summers and urban traffic, have had a high percentage of fp failures
e) saturoworks have identified high temps and addressed them, their implication is the car lacked some final thermal polish
f) fp failures reached a crescendo in europe summer
g) alpine had to redesign the front wheel well plastics to vent more air through radiators because of summer on-track problems.
So unless you disbelieve completely a thermal cause, it is quite logical to hint the French may not have gone that extra lap to check for long term operating temp degradation when ambient air is 30c plus and the car is in traffic - beyond verifying the engine stays within safe operating temp.
Yes, I disbelieve the thermal cause of the fuel pump failure, for the reasons stated above.
You’re covering a lot of ground in your post with many quite unrelated things that we would need to address separately.
The mid engine layout has nothing to do with it really, it’s been done forever and there is a large knowledge base.
Cutting the extra holes in the front plastic arches was definitely an improvement that everyone can agree upon - more airflow out into through the heat exchangers into the wheel arches. This improves the efficiency of the cooling system and is nothing to do with protecting the fuel tank from heat.
Cutting holes in the floor under the heating pipes is, I’m sorry, a stupid idea for the reasons I covered above.
At the back of the car, releasing as much heat as you can is a great idea, since here things are much more serious but not fuel tank related. The key difference is that you have the exhaust - and so now there really IS potential for too much heat, brittle plastics over time etc The rear undertray cover isn’t a shear plate from what I can see if it, so if you want to cut holes in it and put grilles in that then I reckon that’s all good and I can definitely see that helping. Here we absolutely agree that the less heat the better, and there is scope on the table to improve it easily if you wish, unlike at the front where most things are already done brilliantly.

I’ve been curious about the heat-soak explanation myself as mine failed on a cool summer evening in light traffic (thankfully!) on an A-road driving down through Kent.
Neither pressing on particularly, nor stuck in traffic, so it seems unlikely that the fuel-pump was particularly hot at the time. Unless a manufacturing fault meant it was generating additional heat of its own…!

I was curious as to when the official recall would start in Germany after the UK squad got their notices.
Last week I got mine. It‘s cute that it says „don‘t wait the fuel pump to be checked/replaced until the summer tire fitting“… well I got my service appointment for February.
I am using my A110 as a daily so I hope everything keeps on working until that date.

May I ask which production date (month, year) your car is please? So far, the two Dutch dealers are not supporting any recall for the fuel pumps.

They say they will check the pump first and then decide whether it needs replacement and they would also do a software check.

Just called by my Dutch dealer for a fuel pump change, it's a MY22
Me too, for a MY21 LGT. So, at long last, the Euro wide recall is indeed happening. Hip Hip!Is there a way to check that the replacement fuel pump type is indeed the "final tried and tested" variant apparently now fitted to all A110's since November 2022? And not a variant which Alpine used previously, and which also failed...!
On the recall order I received the following part numbers which will be used:
- 6020019628 - fuel pump
- 7701207449 - tank vlotter ring

Mine was fitted early Nov 2022 and was confirmed by Alpine Customer Services yesterday as having the latest (and greatest!) versionIs there a way to check that the replacement fuel pump type is indeed the "final tried and tested" variant apparently now fitted to all A110's since November 2022?

No idea about Belgium, but whilst at my dealer, I was told that the process is very tightly controlled by Alpine.
They initially received only five, pre-allocated pumps, and the relevant owner is contacted and asked to arrange the replacement being fitted. As each pump is fitted to the ‘vehicle designated by Alpine’, they submit the paperwork, and Alpine send them another pump pre-allocated to a specific vehicle.
Therefore, they cannot just fit a pump to any owner that asks. If they did, they would not be able to claim the costs back from Alpine and would not receive a replacement for the designated vehicle that didn’t get the allocated pump.
I was advised to contact Alpine to check: “whether your vehicle is affected by the pump recall, and that Alpine have your correct contact details in order that you could be contacted when your pump is allocated”. I was given to understand that Alpine hope to get through all the (UK) affected vehicles by mid-February. I think they meant that, owners would be notified by then, not that pumps would be fitted by then.

Just had the campaign email for mine. So this will be its 4th pump I think 
(second one done at 2 year service, 3rd last year when it actually failed). And suggest last summers replacement still wasn't the latest design, or their systems are a mess.
Still, give them their due they are dealing with it and age doesn't seem to be a barrier to having it done for free, so that's better than some manufacturers would be.

Same here, booked in for 8th Feb to get it done. As far as I know mine still on its original after 20k miles. (second one done at 2 year service, 3rd last year when it actually failed).

I spoke with Alpine Customer Services earlier in the week and apparently the pump and software that were fitted to my car in November 2022 are the latest iteration (second one done at 2 year service, 3rd last year when it actually failed).

Sweden here, I just got a recall notice today.
Interestingly, up here we only got the previous fuel pump recall in May last year, with an 'OTS reference' (whatever that is) of 0DHL. The new recall notice has a reference of 0E6D. By then, it'd already been established that the replacements were duff. At the time, I wrote in this thread:
This new recall is hopefully the newest of the new like everyone else. Two fuel pumps within a year!

A few weeks ago (i.e., May 2023), a letter arrived from France and lo and behold — fuel pump recall! It got a new pump a couple of weeks ago and some form of ECU reprogramming to go with it. The part number for the new pump was the same part number as the pump being fitted as part of the original recall in the UK.
Now I'm nervous I've got a duff one — we're driving down to Germany for a holiday before going to Spa for the F1 race in July… I hope it survives!
I ended up buying extra breakdown cover to cover the trip, but it ended up being fine.Now I'm nervous I've got a duff one — we're driving down to Germany for a holiday before going to Spa for the F1 race in July… I hope it survives!
