I’m having a little trouble during a warm start up for a while now, car seems like it’s going to stall for a 2-3 seconds and goes back to normal. I’ve been getting oxygen sensor faults on both banks now and I’m getting ready to replace it soon but the faults come and go. I’m getting ready to do supercharger snout bearings and coupler so I’ll tackle everything at once. I have checked the records of my car and I don’t see anything about fuel filter so I think it’s way overdue as the car has 130k miles. Atlantic British has the fuel tank cover and filter (part number LR043420) but when I googled the number and checked on the land rover website it comes up just as a fuel tank cover, no filter. Fuel system diagram doesn’t even show the filter. They said I need the whole pump assembly. So here is the question, has anyone replaced the fuel filter on a +/- 2012 supercharged? Is that part number is an actual filter?
And a side question with o2 sensors, hoping it just them but do you guys know if the catalytic converters go bad often? Thanks

Yes that part number is for tank cover with filter. No matter how is listed, the filter and tank cover are one piece for 2010-2013.

Great, that’s what I wanted to hear, It would be a poor design not to make it separate and yet it’s still kind of bad design to have to drop the whole tank down. Thank you!

Not at all a poor design, Some new LR products don;t even have a fuel filter save for an assembly or "sock" in the tank. Dropping the the gives you the chance to inspect fuel lines, brake lines and address any rust issues that may be starting. Don't forget your exhaust system at six years old.

I suppose you’re right, I didn’t think of it this way. And by checking the exhaust you mean for leaks? It’s a bit rusty but does not look bad, only thing I have to replace are the o2 sensors and I was worried about the cats but what are the chances of them both going bad whitin a year apart right?! I don’t know if anyone has the same issue as I do with the warm start up but I’ll post an update here if that worked. Most likely before Christmas

Yet the diesels all have a a nice separate oil filter that lives under the car beside the chassis near one of the X members - relatively easy to change and the tank does not need to come out - I wonder why they did not do the same with the petrol versions.

I cannot see the petrol versions surviving very well in Australia country conditions where fuel is often poorly stored and tends to have extra bits in it that does not do engines a lot of good.

Gary we have the same complaints. Our fuel is really bad and in some of the diesels the filter is in the return!
We fitted the inline filter in some Bosch p38s , the same that is used in the GEMS version. Might be interesting to hear from the Australian owners or garages what they do for the l322s.

Just replaced the fuel filter and couple things. One If you haven’t done it, definitely do it. As I took the old filter out, gas started to pour out from the filter and it was almost black. Two, I can’t judge all the Land Rover dealers but the dealer I bought my car from and it’s the same one the car has been serviced all it’s life, they are bunch of crooks. They made claims that they replaced parts when they haven’t as the parts have production year stamp. Fuel pump said it was replaced back in 2016 yet sticker on the actual pump reads 2011 so definitely during assembly. No way they sit on a shelf for this long. Same issue I had with A/C blower. Same manufacture date. So if you think you had filters changed, fluids flushed, better make sure yourself.

Was it an official LR dealer? You absolutely should report them to LR HQ. At least save some other owners from being screwed.

It’s a official dealer, I could report it but how do I prove it? Parts are out of the car and they might just say I got them somewhere else. I just don’t know how that system works

I would report it to the service manager or the general manager at the dealership. It would more than likely just be the tech that worked on it that did not replace the parts and no one else knew about it. If you even just show them pictures of the parts you got out of the car they will go on that. I know my dealership took it very seriously when a mechanic pulled that stuff and was either written up or fired. Even though it was years ago they can pull up what tech it was that worked on it at the time.

I have seen this many times over the years, We have had a few Bad apples but most of the mechanics are pretty honest. I did a head gasket job on a disco a few years ago that obviously (to a rover tech) had never been off the car. They had done a extended warranty claim on it at a dealership a few years before.
