I made the mistake of buying the Icarsoft LR2.0.

This unit does not work on my 2004 VDP, I can't do updates and it does not even read the OBD codes.......telling me my car is incompatible with OBD which is odd because I have two generic readers and they work fine, they just can't read the Jag codes.

So...........Im done with icarsoft.............and as a result am asking you guys..........who has had a trouble free experience with another reader and I shall certainly look into buying that........Icarsoft are not going to like how I send their useless unit back...........all ill say is that I will be getting some assistance from a cow.

 

The 2004's sadly is not as nearly readable as he later models are with any of the readers

 

Sorry to hear that, and I'm not sure why the 2004 model is different from the later ones. I got the iCarSoft LR V2.0 and it works perfectly for my 2008 X358, looks at all the modules, does real-time measurements etc. Another member ( user x350) here in NZ is getting the Autel kit, but I think it is much more expensive than the iCarSoft.

I finally upgraded my old windows 7 laptop to windows 10 and got the Foxwell 510 elite to work. It was ~$140

 

It has nothing to do with 2004 Jaguar, You got a defective Icarsoft LR2.0. Return it. I had the same issue with the Icarsoft930. My Icarsoft LR 2.0 recently purchased has no issue reading standard OB codes from all Jaguars from 1996 and newer. It did not read code from 1995 Jaguar XJS. I have XJS, XJ6 X300, S-TYPE V6, XJ8 X358.

 

Mine will not read the 2004 engine module, neither will my Foxwell NT 510.
Everything else is fine on both, but the Foxwell is more advanced, than the i930.
Find new features, every time i play around with the Foxwell NT510.
The one that does all the cars looks very desirable

 

Really? ECU is the main unit to read faults I think Just wanted to buy one (NT530) in order not to mess every time with sdd on laptop.

Anyone have also expirience with Foxwell on pre-2006 cars (with VID-blocks architecture)? Please share your expirience as well. Thank you!

 

When I contacted iCarsoft about the 930 they indicated it would not work with the pre 2005 models. The bus structure/data format changed in that time frame and it looks like they decided not to add the earlier layout in the reader. I also tried their higher end unit that could do most of the major car makes. I did not get good results there either, improbable live readings etc. However I do have partial bus shorts which their equipment may not be able to handle. SDD and the car are able to function fine with the shorts - as long as one does not try programming without workarounds!
I would like to try one again, with what I know now, alas the shipping, return cost hassle is not worth the effort. I think a lot of the low end clones may be in a similar situation where they cannot handle the shorts. It is also possible the more rare failures with SDD are triggered by the same issue - particularly module programming.
I do not know how frequent shorts are, however the replacement ABS module I purchased had similar shorts in it. I think the shorts occur in the capacitors that that are supposed to only let the signal on the bus through.

 

Much of the engine information is available elsewhere, on my 510 Foxwell. reader.

Number of the run cycles is one not available on the 04, but is on the 07.

The 07 self identifies the car information, but it does not on the 04

 

I would if they would return my attempts to contact them.

 

Can't read codes on my 2000 XK8 using a basic reader that works fine on my other cars. Get restricted performance soon after start (sometimes 15 mins). Game plan was to rebuild the ECU hoping I could then get codes (and maybe the RP solved). Good approach?

 

If the car runs OK for 15 minutes it is not likely the ECU. Although most modules will go to default it is unlikely it would do so, without a bunch of messages, if the ECU is problematic. A number of readers won't communicate with the ECU in a 2004 XJ8.

 

Thanks. Agree. My Jag mechanic says he's seen just 2 ECU failures in 15 years. I checked the battery voltage. New battery but 11.7 which is the first problem. I'll charge it up and see if I can get codes. Agree choice of readers is important. I'm using an Innova 3100 reader which on the "approved list" in another thread. Nice list of cars in your garage!

 

So battery voltage 12.6. Started the car. Reader says "Read" but no codes. Tried my 2nd reader. It scanned but nothing.
Noticed if the car sits for a day, engine runs smoothly for 10 minutes. Start again soon after? Restricted kicks in almost immediately. Temp related?
Seller did a new water pump and factory hoses.

 

Possibly temperature related but not physical coolant items! It could be your coolant temp sensor - they sometimes go open circuit somewhere up the scale which would trigger a kind of plausibility error.
As far as I know Restricted Performance always gets a DTC. However it is not necessarily safety or emissions related so a couple will not show up unless your reader can read Jag specific codes - most cheapies can't - but almost all will have an OBD code. If your ECU died your reader should come back with comm failure, as it should also with a bus failure.
What colour light accompanies the Restricted Performance on the Instrument Cluster?

 

Thanks for your feedback! My BIG problem is no codes. Zero. My reader is an Innova 3100 ($70). Powers up, display says "Read". I wait, no codes. Neighbor's reader is a good quality basic. Powers up, display says "Scanning". Moving icons. No codes. Dash light last week was yellow. Now it's yellow and red.

 

No codes is a problem. With both lights now lit, if battery and grounds are all good, it may be a bus comm failure. I doubt both of the readers you have tried would not get generic codes. My basic reader is the bluetooth MX. When my ECU lost its programming it would come up with "comm failure". It is possible yours does not time out and just waits hoping for comm at some time.
After quite a few attempts I was able to reprogram my ECU, with SDD, and the MX is now a happy camper.
The vehicle will function with many bus problems, since it has a redundancy built in, and can drop back to default values for many modules. The readers do not have that capability and it may be a bus problem that you are seeing.
The Shop manual has a section on checking the buses for shorts to ground and B+. You may have to do that. It just uses a DVM and the OBD port to check most things. That is where I diagnosed my problems from.
If you see problems let me know and I can suggest ways to home i on the failure.

 

Battery is def good. It's 13.5 and holds charge IF disconnected. However connected, it does drain quickly. OBD specific fuses are ok. The reader does power up but that doesn't necessarily its connecting. Plan to check pins on port (12v, ground). Anything else to check? Am focusing on poor connects/signal strength to port. I've seen plenty of comments about problems with wiring behind the dash. I'll look at Shop manual on shorts to ground and B+ (whatever that is). On the the rough idle, talked to the Jag mechanic. Suggested I check compression and compare left and right side. a 40 psi difference would confirm. Gives me a chance to check the plugs too. He thought the really rough idle might be a skipped timing chain. Typical fail period is 50-80k miles. Mine's got 75. Plastic tensioners so that's possible. Still I first want to pull codes and see what's going on.

 

Your Jag mechanics first suggestion should have been to put SDD on it and get the full set of codes and system health. Anything else is just an educated guess. Jumping to major faults without diagnosis will be a money pit.
Many garages that work on Jags will have SDD and will pull codes for reasonable fee. Since your readers won't communicate that may be your best bet.

 

You're right. Totally agree on not wasting my time and money w/o knowing what the problems are. He did offer to put SSD on it. Problem is that I can't drive there. He can't get to it for 2 months (I've booked an appointment). He's
super popular and has great reviews. In the meantime, game plan is to see if I can get reader(s) to communicate so I've got info on problems. It's a super clean, low mileage CA convertible w/ engine issues. Starts instantly and sounds good. Engine was smooth and quiet on the (short) test drive so problems may/may not be major. If the car's worth it, timing chain tensioners get replaced. Hydraulics get redone on the top. Tranny fluid gets replaced. Etc, etc.
