Hi All, Got my new RR S/C last week and have a few issues, love the car though! back to indy or warranty?

Issues

1- Had reduced power, done some research and turns out could be cooling pump/wiring. is it work swapping cable myself or request new pump?

2- Filled her right up and all was good but then empty-full petrol gauge issue, once past 3/4 no issues to 1/4, filled up to half no issues.

3- slight weep on rear diff.

What you guys think?

1 -Was thinking check pump wiring myself and reverse if required.

2- Keep eye on gauge.

3- request new/refurb diff if warranty covers, gold RAC.

apart from above love the car and everything else is mint!! so don't want to be parted with her.

Hello and welcome.

4.2 SC, I assume?

Reduced power a common issue. It's the supercharger coolant pump (or something like that) which fails and needs replaced. Many are done under warranty and I don't know the cost as that's how mine was done. Link below.

The fuel gauge isn't the problem but the fuel tank sender is. Do a search on here as it's a common problem. The tank straddles the rear prop / axle and requires two senders which take an average reading to send to the gauge. When one sender fails, the gauge flops about.

I'd get the weeping rear diff sorted, too. Si. <This is my name.

I eat rat poison.

A man ain't truly been insulted until he stands buck naked in front of a woman and she didn't even notice. Or care.

Hi correct 4.2 SC

It was my understanding that the sender was part of the pump?

in respect to the cooling, the tech note says to reverse wiring if incorrect, was thinking do this or just request new unit?

get diff sorted under warranty and front diff oils myself.

The electric coolant pump has probably failed but worth checking the wiring anyway, although I suspect if it was wired incorrectly this would have been sorted already in the last 10 years. I had this fault on mine when driven hard, turned out to be a seized pump (check by putting a live and earth feed onthe connections) replacement Bosch part was found on ebay for under £130.

I also had a dodgy fuel gauge and yes the tank sensors are on the side of the pump body. I don't think they are available seperately. I fixed mine (they were corroded) but a month later the pump failed. It's a pig of a job replacing the pump (elbow deep in the fuel tank stuff) so my advice would be to replace the whole pump and filter unit (around £400 for both).
