Hi this is my first post so please be gentle
My Daughter has a 2003 L322 TD6 it had a gearbox failure about 2 months ago and took it to a small garage in Edinburgh he is a gearbox specialist (only works on automatics) after the box had been refurbished he plugged his code reader in and said it had an injector fault and the egr needed cleaned.So she drove the car one month later the gearbox failed again the garage said the pump had failed again and he replaced it with no labour charge but charged my daughter £250 for the parts in the pump and fluid.He told her unless the injectors were overhauled he would not honour the guarantee,he said that the reason the box failed was the injectors so i removed them while it was in his garage £250 bill as one was faulty. My Daughter picked up her car on Thursday night by Saturday morning(70 miles) it failed again.He has removed the box again the torque has a crack next to the shaft the drive from the pump has broken and scored both sides of the bell housing.He is now saying it is because the car is smokey and it is choking itself and it had a headlight conversion (10 months ago) that it was affecting the Can-Bus system and making the gearbox over pressure and break up
I'm sorry for the long post but trying to explain best i can
The thing i would like to know is the garage trying to cover up for mistakes they have made or would any of their excuses make sense the car had the headlight conversion 10 months before the gearbox failed the first time
Thanks for any help

He is talking out of his

Headlight conversion will not affect the car at all.

It sounds as though he tried to fix it one the cheap, which has not worked. Then tried blaming it on faulty injectors.

Sounds like poor workmanship, or faulty parts, IMHO...

^^ What he said!

If for whatever reason the headlight conversion caused an issue on the CANbus circuit, it would likely be limited to the LCM. The individual control unit is responsible for it's own inputs and doesn't broadcast them- otherwise having separate system ECUs would be redundant. IF somehow there was a systematic "flooding/swamping" of the CANBUS you'd have a very poorly car that probably wouldn't work- certainly the dash would be lit up like Blackpool.


That said, did you at any point tune to stereo to radio 1? That can cause catastrophic transfer box failure.

Thanks for you reply my son has taken the turbo out to clean it and he is also going to do the intercooler i think that the mechanic expects my Daughter to pay for the repairs,he has priced getting the bell-housing skimmed to take out the scoring but my worry is it has already been skimmed he sent it away before would that not increase the pressure in the box.He told me has built hundreds of these boxes without any problems
Thanks for any info

Can't see why he would have to get the housing skimmed, if the TC was loose and scored it then it shouldn't be an issue with one that is correctly working...

As said above he is talking even the injectors and EGR would have no effect on the gearbox, the oil pressure is decided by the pump, it is mechanical and not controlled by the ECU.... Pete

Dont garages talk a load of bull just to get your money, there seems very few people to trust these days as everyone is out to make a quick buck.

@ JPS, yes, very sad. I have to say I hear it in my industry too (telecommunications) chancers spouting what they feel sounds like plausible buzz-wordy tech jargon when the content is largely b******s

I'm pretty fortunate that I have a decent set of tools and will happily take on most jobs myself as it does appear to be something of a lottery... That said a gearbox rebuild would be getting farmed out to a specialist!

@Sauzee, I hope you get it sorted.

I would be looking to recoup my outlay to him via the small claims court. Provision of goods and services act 1979, and have it fixed properly.

Talk about grasping at straws!

The old "when you're in a hole, stop digging" comes to mind. If he doesn't know what's wrong with it, just say so and stop spouting total sh te and asking for money for things that are clearly not faulty!  Got - 2017 SDV8 Autobiography in Loire Blue

My gearbox went last year I was advisedvto take it to Mackie in glasgow Auto specialists . First class job with 3year warranty . Not cheap but good . No one in edinburgh recommended

Thanks for all your replies,Swiftman this guy worked for Automotive Automatics in Leith for 8 years then started on his own about a year ago the only reason i took it there was because i had no way to take it to Glasgow as the car did not drive at all. She has already spent £2400 plus £250 getting the injectors done my son said he was down at Leith today so i think he was at his old work to see if they could help him i will hopefully find out tomorrow what he has to say
The part that had milled and that has broken again is where the pump and the bell housing meet i also remember that when he first built the box he said her bell housing was to badly scored that he used a housing from a scrap BMW box so does anyone think that may be the reason for two failures
Thanks

Hi I had mine taken through by recovery firm , mackies will collect car but I think it's about £150 for them to collect . When my box went I had to get gearbox , torque converter & transfer box all replaced . Plus mackie insist on a new oil cooler being fitted .

Agree with all of the above. Don't take any

Though to be fair, my car has brighter bulbs in the reversing lights. This could have caused your daughters gearbox to fail. Oh wait.... Hang on......

On a serious note, each unit attached to the ibus identifies itself with a device id and when the devices send data out, the ibus packets contain the id of the unit its destined for, so the gearbox ecu will not do anything with data that is not meant for it.

I have a PDF of a doc called "the ibus inside out". It's on the net somewhere. Take a copy with you so he can explain what's going on

Trading standards me thinks could be an option. You really need to give him the chance to put it right, and you've already done that. I'd stop giving him money till he completes the initial job it went in for correctly. 2011 Range Rover Vogue SE 4.4 TDV8
