is that including a donor car?

The only CL9 with factory xenon’s was the pre facelift executive model as far as I can recall. A 2006 facelift type s will have halogen bulbs. Happy to be corrected on this

Yep that’s clutch slip I’m afraid.. could be just a temporary blip so keep an eye but if it persists and gets progressively worse, time for a clutch.

It does sound electrical based on that, and a corroded earth is a very plausible likely cause.

None of these solutions work, trust me. But it’s your money..

If you really want to do a full drain then one trick is to disconnect the transcooler pipes and keep cranking the engine to expel fluid but at the same time have someone fill the gearbox so it doesn’t run dry.. when the colour coming out is as clean and red as the fluid going in then you’ve done...

Read your owners manual, even tells you how to do it in there. Very straightforward. Just drain and refill, there’s no filter to change. And remember on an auto you’re only removing around 30-40% of the oil on each change as the rest is in the torque converter.

It will be perfectly fine. In fact go for a cheaper C2 if your dpf isn’t present anymore ;)

On your auto the fuel filter is underneath the vehicle adjacent to the tank at the rear. The transmission fluid change only drains part of the fluid on every change, just drain from the drain plug on the box and refill from the fill plug. There is no filter. The capacity is close to 8l but to...

Because coding will solve for very minute tolerances that aid smooth running, but not account for the heavy smoking or running issues being described here. The coding represents very tiny microscopic differences in mechanical variations. I’ve been around diesels many years now, this issue is...

Recoding injectors won’t solve that.

Have a look inside the glovebox there is a switch to disable the trunk I believe, that might just be pressed.

To me this is a classic injector issue. I’ve not read the thread back to back but sounds like you just need 4 known good injectors from a running car.

It’s really down to the tester on the day and which side of bed they woke up on that morning.

Misfiring will be down to a bad injector mate. Try running a leak back test before removing them all again

Ah sorry hadn’t realised it was already egr off, I only scan read the thread. It’s worth giving the injectors some time to bed in properly and running some additive through. It’s going to be a fuelling issue now.

Those results look a lot better. I personally think your egr is slightly stuck open and leaking internally. Would suggest blanking temporarily to see if it cures it and then decide if you want a permanent solution.

Get the car properly inspected and diagnosed, this is no way to diagnose a fault. Even our advice is based on guesswork at this stage.

Nope I mean the engine remap. If you’re seeing white smoke and can hear knocking like that, and are confident your injectors are not the issue then in my experience with these engines it’s a poor quality remap.

That my friend is a bad map.
