Thread: td5 abs probs

this is an update of my 3 amigos problems.
To date the vehicle(TD5) has been at the dealer for 2 weeks now, next week will be the 3rd.

Shuttle valve replaced,
rear r/h sensor replaced and wired directly to ecu (one piece of wire).
Tested and still the 3 lights come on.

Land rover Australia contacted with test results of fault codes.
Lots of head scratching and they say take it to an Auto electrician.
End of first week without a vehicle.....

2nd week:
auto electrician test the car all day? and borrows the dealers portable fault code machine. He cannot find any short circuits or anything wrong.
Returns vehicle to dealer....saying it must be the modulator, fit a new one and see what happens?

All this from the dealer and his mechanics.

New ABS modulator ordered (just the front part with the electronics ) and fitted this week.
Tested and still the 3 lights come on. that part cost $1100-

So a test report again sent to Land-Rover Australia , the dealer thinks that there may be another modulator that is not working, but is not sure where it is on the vehicle? (their words not mine).
someone said its under the dash and another said its in the engine compartment?

It seems that Land-Rover do not have the knowledge or know how to repair cars that they manufacture! Sad isn't it?

Week 3: I will update this later

Can I ask a stupid question???
I will anyway.
Has the vehicle had a windscreen replacement recently???,in recently I mean between summer and winter,or wet/dry????
D2s are renown for leaking new windscreens,especially if its non genuine.There are several ECU units behind the glovebox(one runs the ABS),they get a nice shower from the leak.
Have also heard of fully packed gloveboxes causing issues with wiring,but that usually results in an SRS fault rearing its ugly head.
Goodluck

thanks for the feedback, the windscreen has never been replaced, but I guess they will be looking behind the glove-box on Monday, if they know about additional units lurking there

Hi there,
After 4 days the dealer is still waiting for a reply from the Land-rover technical department on the woes of my car.
After fitting the electronic modulator to the ABS unit in the engine bay next to the power steering reservoir, at @over $1100- the lights still came on.
Then assistance sort from land rover tec dept,
The consensus is that the main ABS slab behind the glove box, mounted on the firewall has to now be replaced with a new one!
The mechanic has found the said item and in due course will (when he finds time) access it and try removing the plug and re plugging it in and see what happens,) if the fault codes still come on and all 3 ABS lights too?
This unit part number SRD500070 (genuine land rover) is approx $730 this time.
I still have not had any sort of guarantee that this final replacement will even cure the problem, but they say this is the final part to replace in the system and might be the cure, but.......... no guarantees!
So I am waiting for land rover Australia to advise the dealer of their decision and to press on with the open heart type surgery on my ailing discovery series 2.
parts now replaced
rear ABS hub sensor
shuttle valve to modulator
modulator module electronics
now the ECU main computer slab SRD500070
labour to date over $1100- and ongoing...
total over $3000- and ongoing
so be aware if you own a discovery TD5 series 2 , you have many little surprises in wait for you down the line and that the dealers may not know how to apply the cure?

At this point I would be so far past rope-able it isn't funny. You have more patience than I do.

I always thought the whole point of using a dealer is they have the diagnostic tools / skills / parts system to get to the point and actually fix the damn problem without using your money for them to play pin the tail on the random electronic bit.

Faultfinding by random replacement is pitiful and their effort at replacing a sensor previously simply screams 'Run Away!'

By this point I would be politely but very firmly requesting all my old parts be refitted and a full refund on parts. You are paying for the system to be repaired, not a collection of shiny new parts that achieve nothing.

I realize this is more of a rant than offering anything helpful but I am honestly astounded and annoyed at their attitude and it isn't even my car

Next time you go in to pick up the car just tell them that...

"I have less than a month to live and I have a shot gun in the boot of my other car so....

tell me you have fixed my &^%$ing car!!!!"

Hope this issue is sorted out asap

Cheers

Michael

This sounds so much like what I had, almost identical. I think I mentioned it before that in the end we replaced the ECU, a couple of sensors, and the shuttle valve block. Nothing else to report for the past month or so, the errors have stopped being logged and no more lights coming up. Luckily mine has been covered by the extended warranty so far, otherwise it would've been sold off by now to recover costs.

There was no single cause. The errors were the result of a combination of factors which is what made it difficult to identify where the errors arose from (the dud ECU didn't help!). Rather than trial-and-error it was more a process of elimination where we put in second-hand parts to see what effect they had, but the clincher was a known good ECU from a wreck. From that point the rest of the problems were easier to diagnose. All up, about 18 months.

I totally agree with peter5111

The so called 'Dealer' appears not to know how the whole braking system works and is not trained, competent and honest in fault finding. They need to at least read the RAVE manuals including the Electrical library! It's all explained in plain english!

All mechanics I have ever used for all my vehicles only will charge me for parts that are proven to be faulty and required to fix the problem.

If it were me I would ask for my original parts back and a refund and find a reputable mechanic in my area.

Good luck !
