Has anyone on here changed the A/C compressor on a Diesel S-Type?
Local Mechanic says it is too complicated for him and a more competent one off on his hols.
I thought about removing the front of the car and sorting out the headlights while I was at it.
Looks easier than the Workshop manual method where time isn't of an essence.

 

You may have better success with your enquiry if you post on the UK/Eire forum as most members here are from North America where Jaguar never offered a diesel variant of the X200/X202.

 

As before, go to:

www.jaguarforum.com

 

Have tried there too.
No Replies forthcoming from the UK/Eire area !!

 

Can't see this post/question on the UK site, which is why I mentioned it.

 

It's the first thread with 130 views, the 1 reply was mine regarding whether or not the spring mod could be carried out in situ.
Thanks for the interest,

 

Can't help with compressor problem but my 2004 diesel had problems with electronic hand break, that was until I replaced the battery. Since then no problems with it!

 

I have just changed the battery about 5 days ago, For me the parking brake is working fine now but my wife noticed something a bit strange, anyway her description of what occurred
was obscure to say the least so I will wait and see. The battery went up the tubes seriously in 2 days (Oddly 1 day after having a mechanic attempt to change the compressor.) , many faults but it would still start even with only 6v showing on the battery. I think that in October I will remove the front of the car,and repair the headlight adjustment mechanism and change the compressor at the same time. Can't stand fiddling with bits I can't see in out of the way places.
BTW is it possible to fit a nice 3.8 XK lump instead of the present one.?

 

When you do get around to replacing the compressor, the refrigerant must be replenished by weight, not by pressure as many attempt to do.

The X202 diesel variant holds 700 grammes of refrigerant when fully charged.

 

I had it evacuated and refilled with 700g as per the label under the bonnet.

 

Are you still interested by compressor replacement? I can have a look on JTIS. On the 3.0 v6 it's very very easy, just have to loosen the belt and unscrew 5 bolts under the car. I think that it's very different on the 2.7d as it's a Peugeot engine.

 

Yes I will replace it, I already have the replacement compressor. Maybe I will do it myself and do the headlight gears at the same time. Local mechanics seem to think it is too complicated.
I believe the motor is Ford but is common to Citroen, Peugeot and Lancia. I have seen some parts with Ford markings on mine.
There is not much (None) info on jaguar sites regarding the compressor replacement on the diesels. Anyway time is on my side, I can spend a week on it so removing the front of the car should make grovelling around the engine much easier.

 

I have the manual for the S-Types

 

Sounds like quite the chore to replace the whole compressor. Is there half decent access to the aft side of the compressor? If so, have you considered taking a gamble on the bypass valve modification, versus changing the entire compressor? The actual process is very simple if you can get to small plate on the aft side.

You'd still have to do a full evacuation and recharge. But it might be worth considering. A failure of that bypass valve could show the same symptoms as a worn compressor. No way to really know without trying. Just something to consider. Might save a lot of time and effort.

 

I actually posted about that possibility too, without any replies. But I don´t think it is possible on these. I have tried to see down there with an endoscope

without much success. Btw. I have already done the bypass valve mod on the Compressor that I have ready to install.

 

I just realised I never got back on here. I replaced the A/C compressor in April this year. The job is a real cow, Not having the hose clip tool probably added half a day to the job and the lack of info in the manual regarding the trans oil heat exchanger removal, another part of the job that took the best part of a day. The Manual regarding the replacement of the A/C compressor is a real crock of "£$%^. It is really based on the petrol car with errors written obviously by someone that had NEVER done the job. Bolt replacement sequence is important and is wrong in the manual. Shortening one bolt by 4mm made a great difference. BTW for all doubters the compressor comes out the TOP !! Anyone who says differently has never done the job. Anyway after Klaus's invaluable help with the fault analysis and the decision to change said compressor I now have controllable cold air and her indoors is well content, especially when riding with me when it is 34C+ outside.

 

I have a 2004 2.7D, manual, 6 speed since 2006. Great car, pretty reliable. Only real problem was electronic hand brake which often did not work, just parked in gear. Problem disappeared when I replaced the battery in 2018. The battery was the original Jaguar one which I had never replaced. New one solved the problem.

The car has now been standing at Heathrow since February 2020, I have not been back to UK since start of Corona. Will have to scrap it probably, shame, only 140,000 miles and was in perfect condition.

 

The battery if it was left connected will be stuffed, If it was disconnected you might be OK. With the onboard electronics the battery will go down in in less than a month Check fluid levels. New battery, follow initialisation procedure and you will probably be OK. Depends a lot on how well it was treated beforehand. UK climate might cause damp probs mould etc. Would be interested to know how it goes.
Cheers

Thank you for your advice.
My car has been at a chauffeur parking at Heathrow where they have started the car regularly. I did ask them to use it but unfortunately they did not.
They drove it recently and said the breaks were sticking although I had new calipers 2 years ago.
Big problem has beed water collecting in the boot, where the battery and various electrics are situated.
The car was in excellent condition when I left it but it has been standing for 18 months.
I will probably have to scrap it but the registration documents are with me abroad.
