Ron, Yes, driving around in cool aircon is bliss! Agree totally about scissor jacks. Horrid design and can't be trusted. Best regards David

Sorted. Finally managed to get the time today and jacked the nearside up and removed the front tyre. Removing the wheel arch liner was not easy since the screws were all corroded. Anyway, I disconnected the Alarm unit, replaced F25 in the glove box and hey presto! Full aircon, blower etc. Normal service resumed....except no alarm. I just need to get a replacement alarm unit now and reset the engine light. A final sting in the tail. On fitting the road wheel and tightening the nuts finger tight, I began to lower the jack. Suddenly, the car dropped to the floor. Seems the threaded retainer on the scissor Jack had failed! This is rather worrying. I wonder if any other members have had this problem?? My jack looks like new and even though the car is 12 years old, I wouldn't have thought it would fail like that? Anyhow, best find that alarm unit. Cheers all! David

No worries guys....I analysed the electrical diagrams last night and it would appear that one (of the 3) supply lines from F25 does feed the Active Security Sounder, or as I would call it, the Alarm sounder unit, which is under the near side front bumper area. I aim to disconnect this, replace the fuse and then see if the fuse still blows. This fault is quite perplexing, since a fault in the alarm unit, which is in a vulnerable area to water etc, seems to result in the loss of all these systems! Driving without demisters, heater blowers, air con, etc etc is not very acceptable I feel. If this is indeed the fault, I am tempted to re-wire the alarm unit to a separate fuse, thus leaving these other systems on their own dedicated fuse. (I managed to write all this without allowing my son to configure my iPad sell chekerz!)

Forgot to mention.....I disconnected IP101 and replaced the fuse. It still blew. All this is with ignition off.

Well, sad to report, the plot thickens. Replaced the RCCM and After about 2 seconds, fuse 75 blows again. I understand the fuse feeds pins 1 and 14 of IP101 of the RCCM, but it also feed the Active Security Sounder? I can't seem to locate that on the car, but obviously something is dragging the power to earth, but not instantly....it's around 2-3 seconds. The fuse is 7.5A, so that's a lot of current. Any ideas again, much appreciated. Thanks

Yes sorry Jim. Never can get the hang of this iPad auto spell checker!

Hi Ron Many thanks my friend! Am awaiting delivery of the unit. Driving without Hester, blowers or demisters is a real pain! Cheers David

Update: Interestingly, I checked fuses 75, 80 &99 tonight in the glovebox fuse box and discovered fuse 75 (7.5A) had blown. This supplies power to the folding mirrors module (I don't have) battery backup sounder (don't know about) and the Climate Control ECU. Seems the ECU is duff. Rule 1 then, is not to try doing diagnosis whilst suffering man-flu. Ordered a replacement from fleabay today. Will fit and feedback the results (after carrying out further voltage/continuity checks).

Thanks Guardian. I need to recheck the fuses and earths tonight but have a nasty feeling that the Remote Climate Control Module thingy may have given up the ghost. There's a few on Fleabay but trying to identify the right one is a problem since nobody seems to be quoting the Jaguar 2SC XXXX part numbers. Hey-ho, we soldier on!

Just managed to get a scan tool and discovered there are two fault codes; P1111 and P1699 and the EMS light is on. I'll do some research and post my findings.

I have a 52 plate 2.5 V6 X-Type AWD Saloon with Sat Nav. Today I nipped down to the corner shop and on the way back, the EMS light came on, the air con is not working and there's no blower, demisters, heated screen, or rear demist. On the small LCD below the screen, there is the clock displayed, but there is no outside temp display or climate control temp, so it looks like nothing is working. No lights on any of the buttons. Everything else seems to be working on the car. If you select climate control on the touch screen, it says "Communications Failure - Please consult your dealer". I've checked fuses and swapped the aircon relay with the horn relay (seem to be the same) but no fault found. Can anyone please offer advice as I don't have Mongoose etc. My thanks in advance.

I'm thinking of swapping out the ABS Pump and ECU unit on my 2002 2.5 x-Type. Can anyone tell me if the replacement will need coding, or would it just be a straight swap? Thanks David

Hi Guys. All confirmed. The hub nut is indeed 32mm. You need a deep socket. Cheers

Don't know if it helps, but a interesting discovery for me... Recently bought my son a car. The garage had jet washed or otherwise steam cleaned the engine.Just a few weeks later, it was mis-firing between 2000-3000 revs and running a bit lumpy. Removing the plugs (recessed into the head) I found they were all rusty/corroded. A new set later and it runs like a dream! I think I'd rather have a "honest looking" engine anyday.

David, thanks, but it's definately to do with the ABS as the break pedal moves. I've replaced the N/S/F sensor, but am beginning to suspect the ABS Pump and ECU. Anyway, that's next months project as the Minister for Home Affairs.....she says No until payday. (Wife)

Just for info. 30mm socket arrived today. Doesn't fit. It must be 32mm. I think I'll give up!

Ken and Frank, Thanks. I will get one at the weekend and report back. Best regards David

Hi Frank, Many thanks for the reply. Almost a tale of woe. I bought a new hub bearing kit (it's made by Lucas) but it didn't come with the nut, so I also bought the nut, which Is 30mm. I bought a 30mm impact socket from Halfords after the nice chap assured me it was the right one, but it doesn't seem to fit the old nut on the car. I'm assuming it's 31mm or 32mm, but either way, it needs to be deep/long reach right? The old nut has a castellated style top, whereas the new one doesn't, but does have a integral washer. I've searched the tinternet and just can't seem to find any reference to the correct nut size or socket!

I have a 52 plate X-Type 2.5 V6 AWD and need to change the OSR wheel bearing assembly. Would anyone be so kind as to tell me the correct socket size for the hub nut? I don't have a manual. Thanks in advance

Well, the plot thickens as they say. Just had new disks and pads all round and today, I fitted a new ABS sensor to the NSF wheel, where the ABS is kicking in from. Still the same. The fault is intermittent and seems to only appear slowing to around 5 mph, then there's a twanging type of sound, and the brake peddle judders. I'm beginning to suspect the ABS pump, as the cable to the sensor looks like new-ish. Deep joy. Anyone have any ideas? I'd be grateful. Cheers.

Hi Chaps, Has anyone noticed that Europarts are selling front left hand drive shafts for Jaguar X-Type CF1 Saloon 2001-2009 on EBay, at just £4.99 with FREE delivery??? What a steal! Just got one.

Peter, Thanks so much for the info. Sorry to hear about your car mate. Bring back hanging I say (related to horse thieves you know)! I've ordered a Haynes m annual today, so will find out how to have a go at it. Like you, I'm more of a lump hammer and points guy, but may have a go. Ron - Would love to meet up at Brighton. Chance to blow the cobwebs out of the old girls hair....and the car too. Cheers David

Hello Guys, I just joined having bought an old X Type 2.5 V6 Auto. Really pleased overall, but one issue I would be grateful for advice. Sometimes when braking at junctions etc. there is a clunking sound from the front end and the brake pedal moves slightly. Rather like the ABS cuts in for a second? My local garage reckons it's the reluctor ring on the drive shaft and says the whole thing should be replaced? They haven't inspected the car yet though. Does anyone know about this and if it's within the skills of a DIY'er? Cheers to all, David
