I have a 2017 F-Type S with manual transmission. A couple of months ago it went in to "Restricted Performance" mode which causes the A/C not to blow cold air and limits the RPM's to 3,000. I took it to the dealership and they said they replaced a part that controls the electronic throttle. It happened again last week, so I took it back. They said the same part had gone bad, so they replaced it again. I got the car back Friday and drove it again for the first time today (Monday) and it went back in restricted performance mode again. As a bonus, the check engine icon came on this time. Has anyone seen this problem? If so, any idea what the cause is? I find it hard to believe that the same part has gone bad three times on its own. Something else could be making the part go bad or the part they've replaced twice might not be the problem at all.

 

You need to find out what codes the car has stored.

 

Here's the detail from the last invoice:




It's actually one of the most detailed service invoices that I've ever seen. It seems like the technician was very methodical. That said, the problem hasn't been resolved. I'm taking it in tomorrow and would appreciate any clues that I might be able to provide them.

 

I’m certain they already know this:

Common Problems That Trigger the P2130 Code

• Accelerator Pedal Position (APP) assembly failure
• Powertrain Control Module (PCM) failure
• Throttle Position Sensor (TPS) failure
• Wiring issue

 

Interestingly, I check the oil level this morning after I got to work. It's indicating overfilled. It didn't indicate overfilled after they changed the oil a couple of months ago. Hopefully it's just off slightly and this is unrelated. I'm crossing my fingers that the oil isn't getting diluted. Could diluted oil cause this code?

 

Was the car level when you checked it? I can get "OK" when the car is dead level but it shows overfilled on a very slight (and I mean very slight) downhill.

 

Most all instances of restricted performance I've read about on this forum have their genesis in the passenger seat in the form of those affectionately referred to as SWMBOs.
Sorry, couldn't help myself.

 

It was dead level. I parked it pretty far from where I normally park just so it would be in a level parking space.

 

I took my car to my local Jaguar dealership on August 20th. It literally has not moved in their parking lot since. They "escalated" the situation to Jaguar for guidance. A few days later they got a request for documentation from the previous visits. The dealership has not heard back from them since. Meanwhile, I'm driving around in a loaner Range Rover Velar that had 800 miles on it when I got it and now has over 1,100 miles on it. Either they're not in a hurry or this one has them perplexed.

 

Well, the issue was resolved, but perhaps not. I just have posted an update after I got the car back. It's been doing fine for three months. Then yesterday my check engine light came on. I took it to the dealership and they read the code which was P0507. The Googlebot says this means "The P0507 code means the idle control system has excessively high RPM. The ECU has a specific rpm range the idle is allowed and when it is higher than expected the ECU sets the P0507 code. Once this code is triggered it puts the vehicle into a failsafe mode and the Check Engine Light is illuminated on the dashboard." However, the car isn't in failsafe mode. But it is related to the throttle. Do y'all think this is related to the problem above or separate?


BTW, my wife keeps telling me to get another car before the warranty expires, but there's honestly nothing made that I like better. A manual transmission is a must, so that really thins the field.

 

I made an appointment with the local Jaguar dealership for nine days from now.

I went out to my car this morning and here's what I saw when I got in.


It seems to crank up fine though.

 

A low battery can still crank an engine, but the voltage may be low enough to cause a multitude of system failures. You may have a bad battery, or the OBD port may have been recently accessed.

 

I assume that the OBD port was recently accessed given that they pulled a code. I drove it some today and the check engine light went off, plus there no longer a low battery message. I don't know what to make of all this.

 

It could be a weak battery causing all of your intermittent issues. My car freaks out if I don't charge the battery every few weeks. A Bugati Chiron comes with a battery tender. It's a fact of life with highend vehicles. The higher nominal voltage of glass mat batteries means the alternator has trouble with the finishing stage of the charge and short drives are hard on it too. Your battery could have damaged capacity if its been operating in a marginal state for a little while.

 

The lesson here is that you should drive your F more! At least one 30 - 45 minute session a week.

 

I drive my F-Type over an hour per day.

 

Update: After the battery completely died, I jump started the car and it's been fine for about five and a half months. Apparently whatever was causing the battery to drain was reset when the battery died.

Now on to today. My check engine light came on again. I bought a code reading tool, so I was able to read the code. It's P0507 again. However, it's not in failsafe mode. It actually seems to drive just fine. Thoughts?

 

get used to it, it's a jag, but trust me I feel your pain, my car had issues every week until they replaced the motor and then some even after. I would maybe try a new dealer or ask a good indy, but since your under warranty still I would still use a jag dealer. I would never own this car outside of warranty so I'd say the next best thing is a manual 911, amazing cars

 

I get the restricted performance occasionally on my 2017 S coupe when i'm shifting between automatic and sport manual . When i turn the car off for a few minutes, it returns to normal, but there's a check engine light that stays on for a while. then it too goes away .

 

I had this happen with my 2017 manual base premium at 33,000 miles. Here is tech' s diagnosis and the cure, as it went away:
"Check engine light on due to PCV valve failure. Scan vehicle for codes found codes P2189-00 P2187-00 stored. Smoke test PCV system found PCV valve leaking removed PCV valve and inspected found torn. Installed new PCV valve clear codes and road test vehicle, operating as expected."
This was over a year ago and 3000 miles, so I have to believe, in my case,, it was the PCV valve.. Might be in yours.
