Does the shop you’re using have access to Topix?
Good question. He’s a really good guy but it’s been some years since he was a LR cert mechanic and we all know how times have changed. I may need to just pull the cord use a more modernized shop.

Some independent shops don’t want to pay for Topix access so they use Alldata which often has incorrect or outdated information in my limited experience with it.

I'm sure this is getting old by now but thought I'd offer an update on the "progress". So, the mechanic and I re-aligned and decided to loop in Autologic. They took the wheel and determined the PCM had in fact not been updated as the dealership said they did. They downloaded the update and that took the code away. We'll see if that in truth is the fix over time. I will say, we've never had any of the typical symptoms of a weak pump, just the CEL so fingers crossed.

Please keep the updates coming!

Any updates on this. I had the recall done on our LR4, and within a day the CEL came on. P0089. Went back to dealer and they said low pressure fuel pump. $2377 to replace. Asked about the PCM and they said; ‘sure, it’s $275.00 per hour to do so. I have local Indy shop willing to replace fuel pump in tank for 2 hours billable. I can bring part. Anyone have long term success with the PCM update? Thanks

I did the update to a customers lR4 a year ago and it just came back for the same fault. It’s going to get a fuel pump, which is what we were doing at the dealership before the update was the fix.

Did you do LP fuel pump yourself? If so, what part and where did you buy? Thanks

I had a car I sold the flange and the pump on. That’s what I was doing to all of them. A service writer sold one without the flange cause money. I ended up taking it apart again and putting the flange in it. Not sure if it’s a one way valve or what.
I see this code on cold starts a lot. First start of the day and the rest are ok with no fault.
