Wrong wheels on S-type, would that cause Limp Mode?

[ManoFlem]

Hi All,

I'm a new member. I need some advice. I bought an S-Type and I have constant/daily Limp Mode. I know I have the wrong wheels (XK) Wider on the rear. Everything else has been ruled out. Would the incorrect wheels cause the car to go into Limp Mode? Does that sound like a likely cause?

 

Any help and advice appreciated.

 

Regards

Mannix

Welcome..

No, wrong wheels wouldn't instigate limp mode, that's there to protect the engine/drivetrain from further damage, if anything, they would affect the handling.

When you say everything has been ruled out what has been done exactly??

Has it been put on a code reader?

Also, what engine is it? V6, V8 or diesel??

Auto or manual??

Hi Andy,

Been through a bunch of mechanics and found a jag specialist. New throttle body, service recently. ABS faults. I get Parkbreak/ DSC Engine Fault. Error. Yes he read the codes and Pinter it all back to wrong wheels.

I bit of more than I can chew with this car. Out of my depth. I will get the correct wheels, limp mode will probably come back then I'm lost.

It's a 3L V6 Sport , 2002 Auto. Petrol

[Mr Lawrence]

Have you checked your battery??

Usually the first codes thrown up due to an aged battery is parkbrake and dsc fault.

Do a search for jaguar s type battery for more info.

These cars need a tip top condition battery to perform.

I can honestly say I've never heard of the wrong wheels making limp mode activate.

[ManoFlem]

I thought the battery was changed, but under my watch. So it's at least 18month old. Was told it was recently replaced, so it would be no more then 2 year old, but that's what I was told.

I get DSC error/ Parkbreak fault/ engine fault. Xmas tree dash. Limp mode.

I will bring the wheels back to originals anyway and look into probably buying a new battery.

It's a shame as its a lovely car and everyone loves it, but this constant limp mode is turning the car into a major lemon.

[ManoFlem]

PS: thanks for your replies btw Andy. Really appreciate it and all assistance.

Do you think a standard battery in halfords is a good idea, can they be trusted to give me what I need? or do I go to jag?

[Mr Lawrence]

As long as it is for the jaguar S type and not an X type!!

Halfrauds muppets aren't the best.

Make sure the numbers match.

While the batteries off hold the battery leads together as this "powers down" the car quicker and deletes any errors.

ONLY WITH BATTERY OFF THE CAR!!

[Mr Lawrence]

Euro car parts is a good bet, probably cheaper than halfrauds.

[ManoFlem]

The car appears to be ok battery wise. Meaning all works and everything seems good. I'm not a mechanic so don't have the tools to checks volts etc. I will get on to euro car parts anyway.

Would there be a big difference with X and S type batteries?

Hi Mannix,

 

The s type battery is quite a powerful one, a lot more than the x type.

 

A member bought a car from a small dealer and found loads of minor faults.  He sent me a photo of the battery and it would have just about powered  a mini. A new bigger battery and everything worked.

 

My s type has a Varta 95amp hours.

 

You can get batteries at quite a few places if you shop around.  Andy has given you a good supplier.

 

Peter.

[ManoFlem]

Thank you Peter. I will investigate the new battery. Will be surprised to find if the jag specialist never flagged it last week. I felt like a numpty considering the E-types etc they deal with... Sent me away saying change the wheels...

Is it possible with the car running so poorly in recent times that it could knock the socks out of the battery?

[KEN33Y]

I would disregard any comments by the so called Jag specialist regarding the wrong wheels. Does it come up with limp mode lighting when the car is stationary?

[ManoFlem]

Hi Ken, Yes it does, and it done it today (again). Picked the car up , no lights or errors, drove for about a mile. Parked up turned engine off, went to put the windows up and turned the key and as electrics all come alive, ERROR/ PARKBREAK/ ENGINE FAULT/DSC ERROR. Red and amber lights. Put window up. Turned it all off, locked the car. Went to have a bite to eat come back an hr later. Got in the car and drove 3 miles home with no Errors or lights.

 

I get limp mode when the car is in motion also. Is a faulty battery going to do that also? Doesn't the alternator charge the battery when in motion?

 

Cheers Guys for all assistance.

Mannix

[O.T.H]

I would also say battery at fault .????

I am also getting a hyper active idle when stationary. Hopping at 750 and dropping below 500rpm. Even after just 10 mins of driving. New Throttle body replaced last week...

 

If its the battery, I will eat my hat

[Mr Lawrence]

Keep us posted.

I have a nice hat recipe when your ready!!

[ManoFlem]

HAHA! I will have to dig up my Sombrero for the occasion!

 

OK, The plan is a set of second hand wheels from eBay. Already discussed the deal with a supplier who has posted to me different bits already. So they should be ready for dispatch tomorrow. I checked a jag technical spec. 4 x 17" tyres 235 / 50 / 17 (If I remember). 10 spoke Alloy. Supplier assures me they will fit my car.  He asked for VIN number to double check. Plus 10% discount.

 

New battery from Euro Car Parts...

 

Wish me luck fellas. I cant do anymore with this car. I'm at the end of the road ...

[Russ68]

Good luck Mannix, I've been looking for a set of staggered R wheels for my sport, so what do you have on at the moment and are you selling them? PM me if you prefer ;)

[ManoFlem]

Hi Russ. I have a set of XK wheels. That's what I was told they were. 5 spoke 18" Alloy. Really nice wheels actually and I just done the tyres on them also, so a nice newish fresh set.

[ManoFlem]

PS: Got in the car this morning, drove 4 miles to work, no bother. Lol. Changes like the wind... Can I go somewhere local and ask them to check battery? Would they have a gadget for that?

[Old Peter]

Hi Mannix,

 

Plenty of local places such as Auto Accessory shops, Halfords Auto Centres etc will check a battery, usually free.  Simple job.  I would like to bet that some members have the gadget needed.

 

Peter.

Just read a whole big thread regarding limp mode on a sister jag forum. People there saying moisture getting into the The Throttle body and sensors. But I had that replaced. Could there be something else letting in moisture? Im going with wheels and battery, but surely it can't be that simple a fix? There must be something more serious which is fundamentally wrong with the engine? and the whole setup ...
