The fun of breaking down

[grimliver]

So i did 80 miles on the motorway, it didn't regen so being the impatient man I am I forced a regen which it did successfully so for now problem fixed
Tomorrow oil filter and oil change

[Howy]

Here's a better pic

Normal,you can see the gasket is sitting on 'raised' outline.

Now carry out a passive regen to bring the saturation level down further
Ot you will be doing the same again soon.

I'm going to scrap the car, rear locked up

And then I get the warning

[grimliver]

Ok the wife has spoken its going to the garage it's her car I'm not allowed to scrap it! Happy wife happy life

It needs a Haldex service.
If the wheels locked up it may need a bit more.

[grimliver]

Any ideas what these means and is it something i could attempt? Garage wants 400 to diagnose and said if it's the haldex they would only replace not repair at 800 to 1000 smackers

RDCCM (Rear Differential Clutch Control Module) 1 problems exist 1.C0408 Rear Differential Clutch Solenoid Valve Stuck EBCM (Electronic Brake Control Module)

1 problems exist 1.U0136 Lost Communication with Differential Control Module - Rear Invalid Data

These fault codes indicates that the module for the haldex system is dead or broken. It needs more diagnosing

This is the Differential solenoid valve. If this is full of oil sludge it will likely explain the fault code.

So i can change that solenoid on the drive and is this the right kit to do the service?

And what do you think about this

https://www.haldexrepairs.co.uk/product-category/haldex-controller-units-ecu-dem-rdcm/

Dose the rear diff share the same oil as the haldex or is there a way to drain and fill the diff too?

Sorry just a quick question here, how does the DPF regen works? Do u just need to drive the car for some good mileage on the motorway and that will automatically clean the dpf or how does it work?
Had recently used OPL Monitor and got this screen for the DPF, not sure what's the DPF mileage is (miles before ur dpf level reaches 100%??), dpf levels had ups-downs roughly around 55%, though my journeys are mostly on the motorway (~100 km everyday for the past two weeks).

My dpf will passive regen at motorway speeds over a 6 minute period when it hits 65 to 70% a forced one is where I plugged a computer in and tell it to do it whilst stationary which isn't ideal as it subjects the oil to very high temps and requires oil filter and oil change aftewards

First thing to do before firing the parts cannon is the run a full diagnostic test on the haldex system and see what codes you have.
a good test is to put the handbrake on and see if the haldex system disengages then release the handbrake and see if it frees up .if it dose them it's leaning toward the pressure sensor.
a failure of the haldex unit will not lock the wheels its more likely the pressure sensor
ive never known a haldex unit lock up due to failure.
another way to check is to jack rear of the car up one side and support on axel stand and see if you can rotate one of the wheels.
but diagnostic test first .

[grimliver]

Unfortunately my tester will only give me those codes, its worth taking apart to clean it anyway right? I have had previous issues where the e brake would stay on so I'm tempted to also copper grease the sliding pins,
Where do I find the kerb weight of my car I was going to buy some ramps but they max at 2 ton

[grimliver]

What oil goes in the rear dif, that kits for the haldex service

[grimliver]

I'm not sure if this helps work anything out, I put the car in neutral couldn't move forward but could push back once I pushed it back it would roll forward past it's starting point,
