I do have after the first year quite some rust on the exhaust and other parts underneath the car ... Is this normal? I drive in Switzerland and they told me that this was a car which was imported from Gibraltar and therefore it has another "conservation" .. can this really be true?

 

Pictures, please. Hard to believe since everything under there is either stainless steel or aluminum. I could understand if the fasteners are rusting.

 

Welcome to the forum jonbon,

Over the years Jaguar have consistently managed to find a grade of stainless steel for their exhaust systems which rusts in the northern European climate! However, I'm surprised a recent ex-Gibraltar vehicle would be affected.

The Jaguar Land Rover distributor in Gibraltar is A M Capurro at 20 Line Wall Rd, Gibraltar GX11 1AA (tel +350 200 75149). I keep their details in my phone as I drive down to Gibraltar most years. A call to ask what they know of your vehicle may provide some useful information on its history.

unfortunatly all steel parts e.g. the subframes aren't protected sufficiently against rust .

Even on my car which has been driven only 3 times in rain during the last
4 years you can find some rust on these parts .
Definitely not build for winter use .

Would it be worthwhile to spray it with oil, or is it likely to create more issues?

 

They spread rock salt on UK roads in winter to prevent ice build up. If there's any stainless steel and aluminium in direct contact, that would be bad...

 

Your properties of materials must be different on that side of the pond. Here, salt will not affect stainless, and the surface oxidation on the aluminum (maybe not on aluminium ) actually protects from further corrosion.

 

Think he's referring to the fact that if stainless and aluminum are in contact with each other, galvanic corrosion can occur. But presumably, that would simply be bad design.

Yes...that be true. The stainless pipes are physically isolated from the body with rubber mounting blocks.

 

He is. For a home science demonstration of this, put a stainless bolt and a cola can in the pan after you've Brined the Turkey and connect them with a voltmeter.

Or, if it's an "aluminium" pan you're using, just add the bolt.

Footnote: If you use your boat in anything other than freshwater, go and check that there are no instances of stainless steel/alloy contact...

 

Its even worse with radiators or intercoolers that are piped to some other bit to result in mixed metals contact across a fluid medium. Ever seen a high-end custom computer where somebody used an aluminum radiator and a copper water block?

 

Is there anything that can applied to prevent this from happening?

 

Good question. I'm getting ready to possibly take my SVR with me to live at the beach....

 

I don't think any beach within a couple of hours of Highlands Ranch, CO should cause trouble.

 

Check out the savage geese video below. They comment on the rust issue as well--and suggest it might be warrantied
