Hi All,

Hope everyone is well???

Hope all vehicles are behaving themselves!

As always any questions/issues just let me know!

Many Thanks

Mike

 

Does anyone at Jaguar at least take note of the common faults and arrange that future vehicles will try to avoid them?

E.g. for the S-Type there are poor quality plastics used for things like the coolant header tank and the headlamps. Poor coolant hoses. DCCV is a joke. And so on.

These sorts of things should at least be used as a learning experience so that new cars don't suffer them.

The constant changing of audio/video communication paths (buses, networks, etc) and the lack of openness / open standards also seem daft. It just hurts customers.

Many other car makes are as bad, though not all, but it would be good to be lots better than the current situation.

Er, sorry if this wasn't what you meant! Oh, and please don't think I'm trying to say the cars / S-Types are bad - I don't think that.

 

Hi Mike,
thanks for the post, good to know you're still around and helpful as always.

JagV8 - I think that was feedback for Mike rather than questions....lol

 

Mike@Jaguar.

You seem to offer the membership free general advice (read the small print which "not direct technical advice), whatever that means?

However, can you with your vast experience, confirm if the MY1990 XJ40s Sov Vin 63 etc etc had infa red keyless entry or was it RF??

Look forward to your members' advice.

The question is at the start. The rest is context.

 

JagV8 - Every time a vehicle visits our dealerships for warranty work then the failure/issue is reported back to Jaguar directly. We then use this data for research and development on future vehicles. Also if a dealership sees a trend of failures then they have the ability to notify Jaguar.

Michael Prichard - If you send me a PM containing the full VIN of your vehicle I can check this for you. Based on the information you have given I wouldn't be able to find that information out for you.

Many Thanks

Mike

 

These won't be warranty failures and I doubt dealers will report back. You'd be lucky indeed if they bothered.

Your company can learn for free by reading forums to see what actually happens, without hoping that dealers will tell you. I was hoping that reading forums to find user experiences, particularly of faults your company could avoid in future, was already something that your company actively did.

 

OK, here's a few questions that have been bubbling around the XK forum recently:

• Are the adaptions learned by the TCM lost (i.e. reset to factory settings) when the battery is disconnected?
• Do the active exhaust valves on the 5.0 XKR/R-S open when Dynamic Mode is selected?
• Does the Adaptive Damping system change its settings immediately when Dynamic Mode is selected, or does it take up to 30 seconds like the ECM changes?
• Should permanent wiring for a battery maintainer on a 5.0 be connected direct to the battery terminals or should it be connected 'outside' the battery monitoring module (so that the charging current can be seen by the module)?
• In 'S' mode on a 5.0, does torque-converter lockup happen faster than in 'D'?
• In 'D' mode, does an XK/XKR normally select 2nd gear when accelerating moderately (i.e. not full throttle) from a standstill?
• Does keeping the key fob within range of the sensors of a car with keyless entry cause increased battery drain?

 

Hello,

As I personally am not technical I have sent your questions over to our technical team. As soon as they respond I will let you know.

Many Thanks

Mike

 

Hello,

Please see response below:

1) No the transmission settings are not lost when the battery is disconnected and are only reset by SDD.

2) Active Exhaust System (Supercharger Vehicles Only)

The position of the exhaust valves set by the engine control module depends on engine speed, throttle angle and operating mode of the transmission. At startup the exhaust valves are always open, to enhance the exhaust sound.

When the transmission is in the manual (sequential shift) mode, the exhaust valves are permanently open. When the transmission is in the normal or sport mode, the position of the exhaust valves depends on engine speed and load

3) Adaptive damping settings changes immediately

4) Battery conditioners supplied from Jaguar Features integrated wiring and a dedicated DIN socket within the loadspace area, providing convenience and ease of use. part number C2P24103. But yes if you are using a normal charging leads red leads goes on the positive post and black lead connects to a chassis ground point.

5) No changes is s mode change the transmission software maps only

6) This can happen depending on how enthusiastic the driver is, This is to provide better torque and acceleration.

7) No as this requires the customer to open the door handle before the controller area networks are woken

Hope this helps.

Mike

 

Thanks Mike.....nice to know you're still around helping Jaguar owners on a daily basis.

Its a fantastic initiative by Jaguar and certainly appreciated here, I do have a question though, as asked before....

Why are Jaguar America not as pro active in adding their version of Mike to forums such as these?
We have thousands of US / Canadian members who would use this if it were offered.

Is there someone you can speak to your end, or is there someone we should contact to ask the question?

I know its been asked before, but things change, can you please advise?

Many thanks

Jim

 

Hi Jim,

I have notified the US of your views and opinions on this.

Unfortunately it is down to their personal marketing/after sales strategy on where they feel the best places are for them to represent the company.

Should anything change I will let you know.

Many Thanks

Mike

 

Thanks, Mike - I'll cross-post the Q&A to the XK forum.

 

Thanks Mike, appreciated

 

Mike, the answer to question 6 (about what gear the car starts from in 'D') has just stimulated further debate. 4.2 owners with the 6HP26 gearbox say they have tried all levels of acceleration, and counted the changes - the car always starts in 1st. 5.0 owners with the 6HP28 gearbox disagree.

The problem is, the answer you got is sort-of "Sometimes/maybe". Can you ask again, and get some more detail? - Thanks

 

Hello,

Unfortunately there isn't anything more that can be elaborated on.

It all depends on the driver and their individual driving style.

Many Thanks

Mike

 

OK, a new question:

The door label on my XKR 75, which is (in effect) a Speed Pack model, says the correct tyre pressures are 36 front, 33 rear. However, the Jaguar specification sheet says the reverse, i.e. 33 front, 36 rear for all 2010+ cars - except Speed Pack cars, which should be 36 all 'round.

So, which is correct for normal XKs & XKRs, and what should Speed Pack cars use?

 

Hello,

Please follow the Jaguar specification sheet.

Many Thanks

Mike

 

Hi Mike,

Are there paint codes for wheels or just for bodywork? I've bought another set of wheels for my car I'd like to get refurbished in the original colour (they've been done in black which I'm not keen on). Specifically they are Cremona wheels as fitted to a 4.2 XKR Portfolio.

 

Hello 8bit,

I have just seen your other message about this and was about to reply.

I have just emailed my product team to find out if there is such a thing. As soon as they respond I will let you know.

Many Thanks

Mike
