Hi all, my car is coming up to two years old and due it’s second service. I asked the dealer how much it would be to change the rear diff oil (P380 RWD LSD) and he has quoted £190. This seems quite steep from other posts I’ve read. The Castrol BOT 720 oil seems to be around £40 per litre, so they’re charging £150 for labour. Is this really a long job? Could I do it myself as it’s additional to the required service schedule? Anyone know any indies in Wiltshire/Hampshire area that have done theirs for less? TIA

Hi Gusa, my brother did mine for me as he's a mechanic I watched him it seemed prity straight forward as I remember, he did have some kind of pump that he used to replace the oil I can ask him what it's called if you want.

Thanks, I’d appreciate that. How long did it take him?

For a dealer with a ramp I’d give it 20 mins tops.
It took me maybe 45 mins but that’s with ramps and taking things steady.
You use a suction pump to remove all the old oil when it’s a bit arse high.
They’re probably charging £50 for the oil and a half hour at £200 per hour - including coffee 😂

Hi Gusa, sorry for the delay it took a while for him to reply, it took him about 30 minutes and the tool he used is called a transmission oil filling tool they are around £50 to £60.

Thanks for the help and advice, I think I’ll look at doing it myself.

Might be dumb questions but anyway...

What is a suction pump needed for when the oil will drop out of the drain hole?
Is it not the correct amount when it starts to run back at you from the filler hole?

The pump is used to re-fill via the fill port once it has been drained out and drain cap put back on , and no you don't just fill to it runs out aparantly , I read about doing it on the yank forum so put in the 860ml , but this is for the v6 models only with the LSD diff , the 5 litre cars take more over a litre
