What did you do to / for your E53 today??

Then, coincidentally, my AC didn't work this weekend. It was the first time I used the AC this year so I wonder if it was something I did (maybe bonked or yanked a sensor or something while reinstalling the fan) or if it has been broken for a while. Regardless, I ordered a used Bentley manual from ebay to try to diagnose it. Camping season is coming up and I need the AC while towing my family and the trailer through the hot summer. It's a non-negotiable...

Start a thread about your AC problem.

I ran my 3.0d like that for a while, while waiting on a new viscous coupling after the original died (bearing failure). Engine temps were fine, in fact warm up seemed slightly quicker and engine was certainly quieter.

I was a little worried about how hot the acoustic cover got though, especially near the EGR pipe etc. at the front - almost too hot to touch after town trip at slow speeds... I've seen pictures of these covers melted away at that point....

My EGR pipe is not water-cooled - just a bare pipe, so maybe that adds to the heat radiating from it, compared to the water-cooled EGR pipe I see on euro cars.

Fitted the new (OEM Hella) viscous coupling once it arrived from the UK and the acoustic cover is much cooler...

I got mine some years ago from Depolights, they were a perfect fit, I have since then updated to LED Angel Eyes made specifically for these.

Most likely those melted covers were caused by a leak from the EGR pipe connection (usually that flexi part).

Yeah - that'll do it.

The non-cooled EGR pipe has no flexible section, so no worries there.



One thing I wondered about, after changing my (cracked) stainless exhaust manifold for an XR8 cast manifold, I thought it might be worth obtaining the heat shield from the earlier 3.0d X5 (which had a cast manifold as standard), to reduce the heat-soak from the cast manifold to the boost outlet pipe...

That thick part on the pipe is the flexi part. There has to be something to allow heat expansion due to quite big temp changes.

Now that you say it I think mine had this heat shield when I renewed the manifold. I also coated the manifold and turbo turbine housing with black satin insulation coating.

Yep - but I was thinking you meant flexible section on the water cooled variation...



Nice idea with the coating....

Polished, Buffed out and pushed in two coats of Griot's Best in Show Wax. Got rid of the bird poop splat on the hood too!

Dang Stephen! I can comb my hair in the reflection of that E53!

I have been doing an anal process as always. It sits under a cover quietly waiting for me to wrap it up. Roof is next then she is completely done except the wheels. Going to pull them off, buff them inside and outside add a coat or two of wax and reinstall. I try to do this annually but I am behind with everything going on and one too many car projects. Need a helper for the next projects!
