F Type ear Subframe corrosion

Don’t suppose anyone has the part numbers do they, if I can’t get it done under warranty I will look at replacing the bits myself
 
Your wish is my command:

Brace number concerned are:
T2R 3166 (remove) - Body Brace
T2R 40865 (replacement part)

T2R 18759 (remove) - K-Brace
T2R 40866 (replacement part)

V6/AJ200 variants:
T2P 1597 (remove) - Pt 4 Brace V6/AJ200
T2R 40657 (replacement part

V8 variant:
T2R 3438 (remove) - Pt 4 V8
T2r 40658 (replacement part)
 
Anyone from admin may be an idea to put this as a locked file somewhere for reference. If any others wish to buy the parts for DIY.
 
This issue effects all cars from 2013 to at least Feb 18 when mine came off the production line. The issue is to big for Jaguar to hide. The parts are clear not fit for purpose and will not last a reasonable time for a sub frame. It should be a recall issue and this forum should be pushing Jaguar to recall. My Car is being monitored as it had started to show signs of rust but was not in their opinion rust enough at 1yr old with 4,000 miles on clock. Come on Jaguar listen to your customers who deserve better....
 
Had my 2014 very low mileage F type for a month now & love it but looked underneath last week and nearly had a fit .. it looks like a 20 year old car underneath so I've had the whole underside Waxoiled today as I live on the coast hopefully that will keep the corrosion at bay 🙈🤬
 
Had mine replaced under warranty in March, this was the condition of them on a 2016 Car with 20k, I also bought a tin of black Hammerite paint and got the dealer to give the new parts a coat just to be sure...

That is almost the same as mine was, and mine is stored over the winter, so anyone driving in salty winter road conditions😮.
 
Hi to you all.
I have just joined the forum and am pleased to be a member.
I have a V6s that has 19000 miles, year 2015.
Bought it last year from a dealer (not from a Jag dealer).
A few issues but I absolutely love this car.
I just took it to my local mechanic who is A1...one of the best.
I have a small oil leak on the rear differential, so I asked him to drain and refill so that I can monitor the leak...got him to add an approved sealant added to the oil, we will see if this cures the leak.
On collecting my car today, he told me of excessive corrosion to the rear chassis, unfortunately he didn’t take any photos whilst it was on the ramp. So I googled and found your helpful forum where the problem is identified as poor quality steel used for the rear subframe and straps/braces etc.
I must say, as a degreed metallurgical engineer, I was amazed to learn of this issue on a Jag!
But I see this is indeed a proven issue on F types.
So I have 2 questions for you:
1. Any idea of the price to supply and fit new parts

2: And regarding the differential oil leak, another proven issue on the F type, cost to supply and fit a new differential seal

I had better start filling up my piggy bank.

Regards
Clive
 
It's not actually poor quality steel, it's poor quality anti-corrosion coating.

Part numbers, if you want 'em from "SSM74031 - X152 Under body brace corrosion" (no idea on prices):

T2R 3166 (remove) - Body Brace
T2R 40865 (replacement part)

T2R 18759 (remove) - K-Brace
T2R 40866 (replacement part)

V6/AJ200 variants:
T2P 1597 (remove) - Pt 4 Brace V6/AJ200
T2R 40657 (replacement part)

V8 variant:
T2R 3438 (remove) - Pt 4 V8
T2R 40658 (replacement part)

Welcome to the forum!

I would be having a closer look at them first as it may be possible to just remove them and get them cleaned up, treated and painted/powder coated as others have done.

My local independent was happy to put mine on his lift so I could have a good look around underneath and check, without charge. Maybe you have a local friendly place that could do the same?

My car has the later ‘improved nickel plated’ parts and was already corroding when I got it, so the newer parts aren’t much better. I have treated mine and they now look as they should.

Could be much cheaper than replacement
 
Many thanks for your prompt reply, I’m grateful.
I will jack up the car and look for myself.
Can you tell me how you treated your subframe, I.e. Waxoil? Paint?
 
I used a product from Bilt Hamber called Dynax UB. It comes as a large spray can of anti-corrosive wax which dries quickly to form a dark brown hard firm film. It can be applied over rusted or painted surfaces.
 
If your diff is leaking then think very carefully about putting any form of additive in to seal it. These diffs are so tempremental to type of oil and exact oil levels.
 
Thank you. I used a Castrol gear oil as Jag recommendation and a sealant addition to the oil. I think about 7.5%. Metered exact quantity into the differential. It was not a big oil leak, drained about 700cc of old oil. Car has done 19000 miles. Apparently the sealant may work after a few hundred miles, time will tell. If it works I will post a message. I reckoned it was worth a try, fingers crossed....

Jaguar finally agreed to replace the subframe on my car, but because it was just over 5 years old and out of warranty they said I would have to stand 50% of the cost, I agreed I would pay but on "parts only". They accepted and the full subframe and braces were replaced by my local Jaguar Dealer. I went to Switzerland with a nice new subframe and braces fitted at the end of May.

Job done.

Anyone else with the same problem keep pushing.

Fabulous car for touring the Swiss Alps.
