stripped fred Posted February 10, 2021 Author Share Posted February 10, 2021 I spoke to the Jag independant guy and he went through all the problems and a plan going forward. I won't go through it now but here are my notes from the conversation... Link to comment Share on other sites More sharing options...
stripped fred Posted February 10, 2021 Author Share Posted February 10, 2021 So, the Jag man said that the fuelling is all over the place. He suspects that an injector might need replacing but he also mentioned that even though the EGR valves are blocked off and eliminated from the mapping, that they may be needed to ensure decent airflow. A new EGR valve is a few hundred. He's going to swap the injector's between cylinders to see if that changes things. There is a risk that a cylinder may be at issue, in which case the car will not get fixed, as I'm not paying to put a new engine in. He said the 2.7 diesel is generally reliable. I'll wait to see what is needed engine wise before authorising any more work. The metal coolant tubes are leaking. Quite a big job to replace them. Cost £450. It needs a new ABS sensor on one side with shims, and just shims on the other, cost £100. The gearbox fault is likely wiring and a new wire can be run through, or due to a low battery. I'm happy to leave this one for the moment. The parking brake looks ok but may just need a software update. So, just waiting now to see what the final bill would be. I have a limit but I would like to see it back in the road, if possible. I am prepared to sell for spares or repairs though if it gets too silly. These S types are not worth lot! There are also other cars I want to try at some point. Updates to follow.... RobT 1 Link to comment Share on other sites More sharing options...
RobT Posted February 10, 2021 Share Posted February 10, 2021 Liked for the update. Not the cost element. But it's a Jag after all... stripped fred 1 Link to comment Share on other sites More sharing options...
rickvw72 Posted February 11, 2021 Share Posted February 11, 2021 Mmm. Injector would need coding only if it’s been swapped before and not added to the ECUs program. This is fairly easy to tell, the code is written on the injector itself, and the diagnostics will list what the ecu thinks it has, and you can see it on the screen. Not a massive job, the RAC etc regularly swap and code injectors at the roadside. If he changes the injectors between cylinders he’s gonna need to alter the codes so not sure where he’s going there. Similar vibes from the shims advice? You’d only need shins to increase the air gap between the sensor and reluctor ring. This would alter the signal, not make it suddenly appear / come back. stripped fred 1 Link to comment Share on other sites More sharing options...
Cento16v Posted February 11, 2021 Share Posted February 11, 2021 If its a pre DPF 2.7 then if you blank the EGRs and leave them in place it will be fine. I did it on my Disco 3 with the same engine, made it much less sluggish from cold and had no negative effects. They do have form for crankshaft issues these engines, though if its quiet when running I think that can be ruled out, they're generally very vocal if there's any issues there Edit: I see from the exhaust pipes its a pre dpf one. They're very reliable normally! stripped fred 1 Link to comment Share on other sites More sharing options...
stripped fred Posted February 12, 2021 Author Share Posted February 12, 2021 Another update on this.... The problem swapped to the other cylinder when the injector was swapped so I gave the go ahead to buy a new injector. That was changed today and it seems to be running ok. Something about the fuel pressure being lowered on the other 5 injectors by the ECU but now all reading correctly. The reading from one EGR valve is high (35 as opposed to 5?) But it's not flagging any faults so he's going to leave these. He's ordered the replacement metal coolant pipes so they will get done next week. Lots of coolant escaping now. The abs sensor will also be ordered. The shims are because of a build up of rust. The other job is to get the parking brake working again, but he doesn't think that will take too much. There's also a noisy tensioner but not too bad and he's going to try and get some grease in it as a temporary measure. Overall it could be worse and hopefully I'll have it back next week.

stripped fred Posted February 23, 2021 Author Share Posted February 23, 2021 I spoke to the Jag bloke today. He works on his own so he has to swap the car's about a bit. He ordered a glow plug and fitted it. There is still some smoke at start up but he says it runs well when it's warm. He's going to have another look at the glow plugs. I might have it back to see how it goes, just waiting to hear. I also asked if he could tell me which parking sensor is dodgy, so he's going to check the codes and met me know. This car could go either way, working fine for a while or it could continue giving me some gip. I'm in too deep to pull out now... Link to comment Share on other sites More sharing options...
Crispian_J_Hotson Posted February 24, 2021 Share Posted February 24, 2021 Well it sounds like it's problems are getting dealt with and there's a few of them! stripped fred 1 Link to comment Share on other sites More sharing options...
stripped fred Posted March 9, 2021 Author Share Posted March 9, 2021 I picked the Jag up last week. I am pleased to have it back and it is fixed, sort of. I had a long chat with the specialist before picking it up. He fixed the park brake, replaced an ABS sensor, replaced an injector, reprogrammed the ECU, replaced a long section of aluminium cooling pipe that was leaking and replaced the glow plug module. Once up to temperature it performs well and seems to have a bit more power. It is easier to spin a wheel when pulling out of a junction. However, it does not like starting in cold weather. I will wait to see if this improves when it is warmer. I agreed to take it back and run it for a while. I was previously using it for the occasional short journey so the plan is to take it on some longer runs and get it fully up to temperature. There is also some moly slip fuel additive in there, which I am hoping will help. The specialist does not want to change the glow plugs unless needed due to the risk of causing more problems. Also, this would mean spending more money and the bill is already the wring side of £1k. It needs a minute or two before setting off, there's still a bit of smoke but it clears quicker and, once underway, it goes well. I have noticed the engine is a bit noisier when revved, with a 'tinkly' sound, which I assume is the injectors, but I don't mind this. I have a lumpy cold start video but I don't know how to attach it. When it is earned up it takes an extra second it two to catch, compared with when it was running well, but it then starts ok. I wonder if there's still a leaky injector in there? I drove an 80 mile round trip today. I think economy is maybe up a touch and it pulled well and behaved itself. Disengaging the DSC on a mini roundabout is quite fun as you can hear the rear tyres start to sing. My intention is to maintain it and fix any obvious problems, but not worry about the small things... Link to comment Share on other sites More sharing options...
stripped fred Posted June 5, 2021 Author Share Posted June 5, 2021 So, the jaguar has been fixed and is running well. It seems the problem was a lack of use and lots of short journeys over lockdown. I drove it to London and back a few weeks ago. 200 miles in total. It's been running well every since and no smoke. I'm enjoying driving it now and I even gave it a wash and interior spruce up last week. Just completed a trip to Herefore and back. I will be using it a lot more regularly from now on as more miles to be travelled for work. I plan to give it a polish as I have never done this and the paintwork is pretty mint. It also needs an oil change. Hopefully i will get some trouble free miles out of it now...
