Hello,

Just inherited 2015 RRS. Got a yellow ACE warning light on the dash, haven't taken it to the garage yet, but it's a clear leak as there's a puddle under the car and as soon as fill up the tank it empties over night, now given how quickly it empties I assume it's a pretty severe leak or even burst pipe.

I had a look underneath the car and tracked down the leak to a point, but couldn't go any further. I have come across this disconnected pipe... Anyone have a clue what this might be? I'm hoping it's an ace pipe and that is why it's coming out so fast.

The pipe is underneath the engine, nearside (UK).

Thanks in advance 👍

My bad...added 👍

RR garage said it's likely to be diesel overflow

Took the side under tray off and found the problem, pipe corroded at the front end. Now, RR garage quoted £2k to replace entire front ACE section. The rest of the pipes are completely fine and only need a small section replaced.

There an exact replacement section available on eBay - https://www.ebay.co.uk/itm/267039668354?mk...media=COPY

Has anyone ever done this? Looks fairly straight forward on the books...

I don't think many ppl are working on that age car.

Also this subsection doesn't get much traffic.

You best give it ago!

If you are sure its suitable for your sport model

The gent who engineers the pipes has videos on how to do it too, so should be straight forward - will keep people updated. This could potentially save me £1.9k!

£144 for that?

What’s the price and availability of oem

RR said anywhere between £500-600 for either front or rear set of pipes. Would have to be put on a back order, waiting time anywhere between 2-3 months 😳😅

Can get used ones on eBay for roughly the same prices though...

I mean £144 for a tiny pipe seems steep, but given the alternative options I think it's very reasonable. I had a good look at the rest of ACE Pipes and they're all in perfect condition - I don't understand why it's so common for them to rot in that specific area...

It's maybe different for us up here. If the pipes have rotted through there, they're pretty well everywhere else

All fixed. No more leaks. Was straight forward, used pipe cutter to trim to size. The kit came with compression fittings. Had to bleed the system through rear bleed points - just awaiting calibration and should be good to go 👌

Hi had the same issue myself and used the same pipe from ebay.
No leaks and all fine, after 2 days of driving I now keep getting the yellow and red warnings coming on , either/or no real pattern to it.

Rechecked pipes no leaks - reservoir fine also - bled rear bleed off on the rear ACE pipe -

Any ideas what else I need to check?
PS Did you do calibration via LR software?

Yes, took it to RR garage to have it calibrated and new fluid flushed through. If you had the car running dry at all it's likely that the block is knackered. It's the one that the new pipe you installed goes to. Or it could sensor issues within the bloc.

It's an absolute minefield and could be anything. Does the fluid circulate around can you see it moving in the tank when the car is on?

If it is the block, it's easily replaceable, but costs around £700 -£1000.

Good luck bud.

Hey thanks for the reply.

I had fluid in the car all the time , had a small drip on the same pipe so it never ran dry, and ran fine for 2 days after swapping the pipe out no errors etc , fluid was swishing round after swapping pipe but then 2 days later - nothing .

Is there a separate sensor in the block that can be replaced? I was going to check if a fuse had gone also?
