Exclamation Bad Tune = Big Spend to go back to stock

So I finally heard back from the Mechanic that they don't won't to mess w/ anything on my F-Type.

Apparently, unknown to me or the dealership I bought it from a previous owner replaced the air intakes (one of which keeps popping off according to them), and "tuned" the motor which is apparently causing some issues with the PCM to where they believe it has become corrupted. So much so that an intermittent Misfire on cold start they won't even diagnose until/unless I have them put it all back to stock. Additionally the extended warranty I got when i bought the car will cover none of this as it doesn't cover after-market performance parts. It is quoted at $5400 in parts and another $3000 in labor.

Does this seem right? High? I am trying to decide if I just leave it be and live with the warts, or do I spend the roughly $8k to get her back to stock.

probably get a second opinion with an experienced shop, did you buy the warranty and the car from the same place? if so it should be their responsibility to cover the car as you bought it, so i think theyre scummy for not covering you if that is the case.

That’s my thought as well. It at least runs and drives and even they said it was safe to do so. Once just got to find a reputable shop in the Dallas area. As for the warranty it was bought from the same dealer. It was a Mercedes Dealer btw… should have known Germans were going to try something sneaky w/ a British vehicle (j/k)

Too bad you don't know what tune is on the car. Then you would have a chance at flashing it back to stock.
Never heard of this ever but I only use VAP as my tuner.

The OP didn't say who looked at the car and made that report, was it the Mercedes dealership? I strongly recommend taking it to at least a Jag dealership, if not an independent Jaguar shop, preferably one familiar with the various Jag tunes that are available. Not sure how a Mercedes mechanic would know what he's looking at.

Sorry.. it wasn’t the Merc dealer that looked at it. It was one of the Jag dealers here. Even they said most likely the Merc dealer was unaware of the non-stock intake or tune.

You should be able to just reload the factory tune into the PCM if you have access to SDD.

The dealer didn’t want to muck with it because they said it was “corrupt”. I don’t have access to an SDD to do much of anything. All I have is an iCarsoft to pull the ODB2 readings and reset a couple of the Nag lights

u102768 can you explain any on reloading the stock tune using SDD? I have a tune from VAP and have gone back and forth several times from stock to tuned but always using VAP's tuning tool. I did not know it was possible to get it all back to stock using SDD? That would solve the OP problems too!

I can tell in SDD that the car has been tuned as it is recorded how many times the PCM has been flashed.

I have never used one but from what I have read on the forum I get the impression that if you have a VAP tune you have to use their tool to switch back otherwise you will lose the use of the tune.

In the case of the OP using the 'Configure new modules - Powertrain Control Module' option in SDD should put the PCM back to factory standard:

Isn’t the simplest solution finding and then contacting the original owner. He maybe still able to flash it back to stock for you for free or a few beers

I have no idea about this stuff, but could you get it all overwritten by a VAP tune which most of us have found to be pretty solid?

Doesn't VAP require your stock tune as a baseline?

Not sure but when I had my s60R remapped they just replaced the chip itself because the tune was overwritten at a service (forgive me, I'm repeating words as I recall them, I have no idea)

U102768 thanks for the instructions. Yes I don't know what would happen if I over wrote my VAP tune using SDD? I guess I could then reload the VAP tune as the car would be once again stock.

If you overwrote the tune with SDD your handheld device would refuse to reflash the VAP tune. If there is a possibility for updating firmware during service (with SDD), reflash to stock first. If it were possible to reflash over stock when the device remembered that the non-stock tune was last applied, an unscrupulous shop could buy one tune and flash it to multiple vehicles.

The dealer should be able to restore the original file, so I don't understand why they won't. There is a possibility it could brick the ECU, but they should note that as a risk rather than refuse to do the work.

If anyone is still following this whole deal…. I got the car back today. Everything is pretty much as I left it except I am $400 lighter not including the $70 in gas they burned while they had it.

when I got back to the house I opened the hood and took a look to see if I could see what they heck they were talking about regarding the intake pipes. Well… I saw it…. And I am pretty sure I can fix it, which also means they could have as well.

I actually don’t blame them. The install on your intakes is pretty poor. The left arm (when looking from the drivers seat)is parallel to the brace infront but the right arm there is about 15 degrees on angle. No wonder that joint failed. Because of the angle it enters the sleeve , the ring clamp will never get a good seal and will eventually work itself off again.maybe a new sleeve with another extra inch of length may suffice. It looks like there is quite a big gap between the two ends of the intake pipes.
