Greetings all!! My first ever post and not how I would have wanted it. A few on the ago I bought an approved used 2015 F Type R. Absolutely love it. But since day 1 it has had an intermittent recurring issue.
It will be driving just fine - sometimes for days at a time. Then all of a sudden, warning bong, messages saying E-Diff and stability control not available. At the same time, I can hear relays going off like (again intermittently , but sometimes in rapid quick fire) with audio and infotainment screen cutting in and out and headlights flashing (if on). After a while it goes away. Sometimes it goes away after restarting.
It’s been back to the dealer twice for several weeks at a time. It’s had full CAN BUS checks several times with no issue showing. They thought they’d identified a dodgy electrical control module (relating to diff I believe) as the problem and replaced it but the problem has come back so it must be something else.
Any ideas I could get them to look into this time? Worried if it’s some loose connection etc it’s going to be a needle in a haystack. Really want it fixed rather than swapping the car but not ruling anything out at this stage!
Thanks so much
James
No E-Diff, DSC, flashing lights and audio
My money would be on a bad earth. Some folks have found the stud in the front right wheel-arch to be a good candidate.
Oh, and welcome to the forum, shame it took an issue to get you aboard!

Welcome to the forum.
I'm another who thinks it could be a bad earth or connection.
Here are three separate areas that have caused electrical issues on some F-Types. It’s worth mentioning them to the dealer.....

Check for water ingress into the boot. You’d think the dealer would have already done that, but you never know. You need to take the boot floor trim out and check at the lowest point. Lots of electrical bits in there. Does it only happen following wet days or washing the car?

James, the good news is, it's not terminal!
From the symptoms you describe it's merely a connection issue, be it CAN Bus or Power.
The bad news is, it's a time consuming Pita to trace, especially if it's as sporadic as you say.
If you are so inclined, you might want to purchase a cheap code reader, wait fir the fault to manifest and read the codes.
I'd suggest an Indie, not a dealer to look into this.

Excellent suggestion - it'll save you at least 50% of the labour cost!
The suggestion by gasgas is good, too - if you're on your original battery it may be due for replacement.
