Issue with AC charging/New CCU fitted (Phase One SE LR)

[tsedge]

I guess that has been MG's frame of mind all along, never admit anything is wrong and never admit it has happened before. At least they didn't brand it as a characteristic.

Those who have had the CCU replaced did they replace it with the same unit as originally fitted i.e. 11 kW 3 phase unit or the 7 kW single phase unit fitted to the later cars?

I believe it is like for like, although I have never tested 11kW AC charging to check. There was no change made to the charge port itself, the pins are all still there, but it is possible that it is limited to 7kW.

I must admit I can't really see the need for anything beyond 7kW with AC charging, or it is too quick overnight or during the working day!

It'd be interesting to find out why they fail. Is it poor components, bad design or a software issue.

I seem to remember mine failed soon after I heated the cabin via the app while it was still attached to my charger for the first time.

Usually it is component failure, eg Mosfets blowing up on the circuit board. There's some seriously high currents in a small package. That can happen because of design problems (overworked / temperatures) but it is more likely a bad batch: ie quality control issues.

There are companies now that can repair them, which is far cheaper than a replacement, but no OEMs seem interested in repair, everything is replace, replace, replace.

Software can contribute, eg by creating overworking or over-switching that leads to failure.

Given that these are failing many months in, it suggests to me it is premature component aging.

Update 6:

I rang the dealer up this morning to get a progress report on the CCU availability. One, to remind them that I'm not going away, and two, their track record of keeping me informed isn't the best.

Hopefully it's good news in that they should have the part early next week

Hmm... I'm never keen on suppliers/garages use of the word "should". Saying it has arrived in the UK and is at customs / similar would be more convincing. But, hey-ho, fingers crossed. If it does get fixed next week how long will that have been without AC charging capability?

Amazes me how rubbish dealers are at keeping people up to date. It is the most basic thing that everyone wants. How hard would it be to send a regular email saying: "your part is still on order and we now expect delivery on dd/mm?".

It's not just dealers though. Most companies nowadays seem reluctant to keep the customer informed in case it's not the news they want to hear. When are they going to realise keeping the customer in the dark and false promises winds them up more than anything.

I first mentioned it to the dealer on February 8th.

Some of the delay is because I could only leave the car a week at a time due to the restraint of my insurance only covering a courtesy car fully comp before reverting to third party and the dealer requires fully comp cover. I then have to wait about 3 weeks until a courtesy car becomes available to book it back in again. The dealers had it for just over 4 weeks in total.
