Sent my ECU off to Lynx Automotive for testing and they have come back with it's complex repair, may be done next week, this has been going on for a good few weeks now and I am not very happy. Anyone had any dealings with them or know anything about them?

Also anyone know where I can get a good s/h or refurbished one from its for the DII.

Cheers

Bill
 
Did that! Alive Eng brings up nothing LR related, adding Land Rover brings up TD5 Alive, thought they just did oil burners.
 
Is it the engine ecu?
You can have them programed to any vehicle
So in theory you can use a second hand one

I'm a newbbie on this forum, and I've sent them mine - non-landy though.

They gave me the same reason - complex repair.

They've had mine for two weeks, and won't give any idea of timescales or cost or anything. I said to the garage that had to go through all the sensors to find out why mine wouldn't start, that we could give them a couple more weeks.

Some places say tested within a week and turn-around in two weeks.

I have read other posts that they are good and the garage where I took the car in said that they came highly recommended. I suggested The ECU Doctor - located down in Plymouth I think.

I can afford to have mine off the road for a little while, but if it gets to the end of March I will start to wonder what they are doing.

It sounds like they only have one person doing the work so they might be over-stretched and cannot cope with the volume of work.

If their work is good, it is worth the wait. But if it's not good - no point at all.

I know that some ECUs could be more difficult to test and repair than others, especially if the manufacturer has made many incremental changes, or if there is a weakness that the automated production line built into the units.

I'm keeping a look out for second hand units, but they are few a far between.
 
Well mine is still not back, it's been a month now, although they said on Monday they just need to locate a part now which will take a day or so, so hopeful it will be back next week.
 
Latest: the garage have just sent me a recording of his latest phone conversation with Lynx, scary to say the least the fact is the guy doesn't care, it will take as long as it does and says it's all our fault as you can't run a 4.6 with a 4.0 ECU.

From the Rave:
A single ECM is used for the control of the existing 4.0 litre engine and the new 4.6 litre engine introduced with 03
model year vehicles for the NAS market only. The ECM contains the tunes for both engines variants. When the ECM
is replaced, TestBook/T4 must be used to select the correct tune to match the engine fitment.

All I can say is don't have any dealings with this company whatsoever.
 
I'll give you a few ideas as to how you could have problems with ECU repairs.

a) the circuit boards are interchangeable, so they could buy second hand units and swap out your old unit, but not charge for the second hand unit, but it is called a "testing fee" and a "repair fee", stuff you would never know, unless you are an electronic engineer.

b) Take up so much time that you want the unit back and you are willing to pay the "testing fee" for having had the unit sit on their desk for 2 months and carriage.

c) New unit needs coding to old unit - another charge of £50 or more for doing nothing that some garages can do by hand-held computer. They might even suggest a new chip is required to do it, when the unit is uncoded - depends on the year and make.

Look at what they say they will do - how they test stuff, then read their competitors website and compare the wording. What do their Ts & Cs say? Bigger companies and more reputable companies have more Ts & Cs.

If they charge more than £40 or so for testing, either they are incompetent or trying it on. Any electrical engineer would be able to diagnose an ECU fault within an hour or so. There's only about 6 chips and a few tens of transistors, resistors, capacitors and diodes. Once you have basic data about the failure, some parts of the ECU are obviously working OK, so you narrow your testing to the specific areas affected. Experience helps a lot.

The 4.0 gems or 4.6 and the Thor system are generic by design thus can adpt to the replacement engines.
I have done the 4.0-4.6 many times with no issues and that was before I had textbook to configure the ecu to the correct tune!
Again yes will need the ecu reprogramming but it will only be the security link that needs programing
 
I've just given up on Lynx - no good at all. Bought a secondhand ECU from a scrappy, car's running again. I'm looking for a back-up ECU now just in case this one fails, but hopefully it'll work for many years.

My last few posts were research I did after my ECU was sent to Lynx. The garage told me they were highly recommended........they won't be recommended by me, that's for sure.

My ECU's uncoded and Lynx even tried to tell us that it needed to be coded......if they don't know, what does that tell you about their technical ability!!!
 
If you want secondhand spares, do a search
"land rover breaking for spares"

Don't forget to select UK sites and must have "breaking"

You get a load of special sites up, and ebay, where you can identify landrover breakers and contact them directly - don't use the ebay buying method, talk to the yards directly. If they are big they always put their telephone number on.

It took me a couple of hours to identify several breakers for my ECU, but I got lucky as mine is quite rare.
 
Well I have given up on Lynx too, brought a s/h one that is supposedly winging it's way to us. Hope it's the right one though Rave lists NN100460 & NN100640 when you put my chassis number in, couldn't find any 460s so I have brought a 640.

Lynx really haven't got a clue they said on the phone to my garage that only an idiot would try to run a 4.6 with a 4.0 ECU and that we only have ourselves to blame that it went wrong and yes I have a recording to his rant.

take the prick to court.
 
yet again it is a muppet who raves only trying to make them selves impotant! but really showing it is them who do not understand!

i have it on good authority that the 4.0 adpts to the 4.6 and after 20+ engine conversions never had one back under warranty!
