Evening,

Hope someone can offer advice please.

Okay it's the 2005 D3 my sister gave me because of the never ending problems she had with it, well it's thrown up the HDC warning. Had its MOT last week and had to have new rear brake pipes because of severe corrosion even though it passed its French MOT (CT) late December but otherwise all fine.

Like a lot of cars it's been parked up for months and just driven round the block to keep the oil flowing and the battery on a smart charger. Went out today to move the car to another parking area whilst I cut the hedge, all fine, then brought it back and the HDC warning was on.

With a Foxwell NT510 I've got I got the following codes that wouldn't erase, so presume hard faults:

1: Invalid data received from dynamics control module. Temporary.
2: Invalid data received from steering angle sensor. Temporary.

But looking at the SAS in detail it shows no faults at all. Battery at 12.85VDC resting, all bulbs working.

So may I please ask if anyone is able to offer advice. Been racking my brains to which car I keep, my D2 V8 or this D3, which I've got to say is lovely to drive, can't keep both but this is starting to make my mind up and it's looking like it's keep the D2.

So please any D3 experts out there HELP I could change my mind and keep this.....!

Thank you....Graham.
 
Hiya

indeed know they can sometimes drive u nuts, lol

what codes did it show please, ie , normally starts with a letter, which normally signifies what area the fault is from

• P = Powertrain
• B= Body
• C = Chassis
• U = Network

alas HDC uses a lot of systems to communicate with one another

will ur scanner allow u to see ur live data steering wheel angle , ensure wheels are dead straight and then what the steering wheel angle % is please

u say all ur bulbs are working , does the brake lights also work

There’s a good few of us that own these so plenty of help

ps, are u also handy with a multimeter plse,thks

Hi Gary, thanks for your reply.

The two fault codes start with the letter U. In fact U0416-86 and U0428-86 both Temporary.

I know the Foxwell should see live data regarding the steering angle, but that'll have to wait until tomorrow. Yes all three brake light bulbs are working, they were the ones I was referred to. Yes I can use a DVM, AVO 8 and analogue 'scopes.

I'll look in the morning about the live data. Would from your experience a hard reset be in order or is it more fundamental ?
When I saw there was a problem with the steering angle data I looked at the steering angle sensor module and there's no faults, it passes.

What state does the car have to be to check and or adjust the SAS ? Flat smooth road ? If so then it'll take a lot to find one round here, quite hilly.

But thank you for your time. I'll write again tomorrow.

Hi

ur so welcome and always a pleasure to help

ref ur steering wheel angle sensor , just need ur tyres dead straight , engine running so it’s easier to then turn the tyres , just try and get it on flat ground as possible

hopefully won’t need to start using multimeters , canbus etc

it won’t hurt doing a hard reset that’s for sure

with the landy standing it may of just got some damp into one of the modules, but indeed best to always start with the easy items first

also have a look to see ur wheel speed sensors live data is ok as that can also throw up HDC errors

Plse let us know how u get on and always happy to help
 
Brake light bulbs can work yet be shagged.
Brake light switch failure is a known issue on all makes of cars, just because brake light works does not mean switch is okay.
These were working just fine, but glass is going black, and brake filament has got so hot it has melted one end and its support post, of cousre this changes the reisistance of the bulb.
Hand on heart I have changed them at least half a dozen times in 5 years.

Thank you Gary,I appreciate your help. I'll try the easy things first then get back to you if I should need (read will) need more help. Bloody car, looking at the old D2 now with a lot of new love for it :)

Thank you also for the advice. I know about brake light switches, had to fit three or four over the years with a D1. I'll start checking this afternoon. But you surprise me regarding the working bulbs. Always thought working or not and nothing in between.

I cannot remember the reason for the bulbs messing things up, but it used to be a common question on the D3 forum, and first response was always bulbs and switch, so common I carry spare switch and bulbs in the car!
Lots of threads with various issues being fixed with new switch or bulbs.

I think the problem now is so many systems (on all makes of vehicles) talk to each other, and when one sulks it upsets all the others.
 
Charge the battery, clear the faults just driving it around the block a few times ain't done it any good no matter what the battery reads.

Thank you for your reply, yes I understand what you mean. Maybe I used the wrong word, going round the block where I live is a few miles, enough to get the oils flowing and the engine up to temp. While the tyres are over 40psi hopefully it'll help to stop flat spots. As for the battery, well it was on charge most of last week, I've only one smart charger and it was supposed to be the petrols turn this week, but it's now back on the D3.
Rain and it's my wife's birthday so play stopped at the moment.

Bulbs looked perfect but there's a full set of new bulbs in the car, so changed the two stop bulbs with Osrams which should be of sufficient quality but no change.......
I know the systems talk to each other, wish one of them would talk to me and tell me what the f*** is wrong.

Have an ask on the D3 forum, and see if anyone local has an IID they would plug in for you?
 
Thank you all for your advice but......!

Battery fully charged, stop light bulbs changed, hard reset done. But still have the HDC warning. Okay I've got a lot to read up on, not that familiar with the D3 at all. The Foxwell NT510 reads and erases fault codes but one thing does keep coming up and that's the steering angle, the sensor passes with no fault but the car will not allow me to reset the steering angle which is coming up as a hard fault. No matter how I set the front wheels and the steering wheel are set it will not do what I ask. From what I've already read that can cause the problems I'm having.
So again may I please ask if anyone has any ideas how I can sort that issue out before I look at any other faults which I've read will/can be caused by it. The reason I'm stuck on this is that my sister had the same warning lights on which is why she called me and which ended up with her giving me the bloody thing. Got to say there were no lights on when I brought it back from France and it's only just started again this week. The way I'm feeling I'd give it back to her. Upset I can't sort it and I'm not in the mood to go to an indy unless I'm forced to.

So please any ideas, advice would be gratefully received and gifts given.....;-)

Thanks.....Graham
 
Have you physically checked the steering angle sensor, as I believe they can work loose
Thank you, that I will check. But I do have to find out if the Foxwell will indeed reset the SAS otherwise I'm wasting time with it.
Thanks again.....

Gap IID is the one to get, @ 400+ quid it is not cheap, but they do sell 2nd hand for 300 quid, so it only costs 100 quid to own one for any period of time, sadly you have to have the 400 quid to start with!

I genuinely think if you own an old but complex car, diag kit it as essential as the spanners to fix it.

Yes I fully agree with you, but until January I only had the D2 V8 and the Foxwell is perfect for that, does everything. Seems to offer most things on the D3 but it will not 'see' the engine for what ever reason which it does on the other car.
Still not sure what I'm keeping. Not had much time to drive the 3 due to the unpleasantness. I do like it and if I do keep it I'll get the Gap, but at the moment I'm not spending that if I don't need to. Trying to sort it easily (?) then decide and then spend if I have to. But again thank you.....

Is it an HSE?
I ask as I can remember one guy using the 4a4 screen to make sure the wheels were striaght before reseting the angle sensor using the diag tool, what tool I cannot remember!
It may not need resetting if you cans ecure it in its original postiion.

No, it's the SE without the 4x4 screen unfortunately. Been thinking about the SAS, one of the reasons I've got this car stems from when my sister called about a warning light (final straw as far as she was concerned). She was towing on wet grass and I think it was the TC coming on. But....it did it to me on both left and right turns on dry flat roads with the slightest of bends, no gravel or rough stuff. Only did it a few times and then was clear until this week. From what I've read that can be caused by a SAS problem. Please say if I'm not correct.
Okay, now a stupid question. How does the panel under the steering wheel come off, just clips or the screws I felt running along the bottom ?
