Oil leak from diff

[rabies]

Just taken my beloved in for her first service and on inspection it's sprung an oil leak from the front center diff. Garage informs me that it will be covered by warranty but its a 2-3 day job to investigate and fix

Anyone else had this problem?

[Performance]

"it will be covered on Warranty" are they for real?.
I dumped Audi after buying all there high performers for BMW, never looked back.
I found Audi very expensive on service and parts, and cars were not reliable either.
Just my 2P.
Test drove this RS6 after owning the last one, Bought a M6 Gc Comp Pack, way better bang for buck and got £34K off a new deal.

"Performance":- Hanging out on a BMW Forum might be more appropriate then? Oh, and It is seldom about the money...well not to a true connoisseur!

rabies- only done around 3500 miles- had a quick look and no signs of any external leakage on diffs. At least it is covered by warranty. Hopefully you'll soon have it back and be driving past "better value" German alternatives should they be presented with anything more than a 1:5000 slope if the winter bites! Not that the outcome would be any different if it was a summers day and downhill

Loving your optimism. It is however a touch deluded but each to their own

To the o/p, that seems like another 'we don't know what we're doing' from your dealer as no way it would take 3 days to investigate an oil leak from a diff. Perhaps if it's an uncommon part that's failed it may take a while to source but 3 days to investigate is a bit OTT. That said & to balance things out i don't rate BMW M dealers/service any better than Audi

I must have been "deluded" again this morning...picture the scene...a whole 2cm of snow on the ground, a 1 in 300 gradient and an RS6 (C7) breezes past a "better value" German alternative that was just sitting spinning only one set of it's wheels, much like a propeller blade, half way up the "hill". The plucky RS6 (C7) then soldiered on through the "treacherous conditions" only to happen upon another German alternative 3/4 of the way up, again spinning only 1 set of it's wheels, much like a revolving 3 pointed star, At least it made it further up I guess. That said the Astra in front of me also seemed to manage the "treacherous conditions" without issue...maybe Opel also belongs on the list of "better value" German alternatives??

So, NO

Leaking diff shouldn't take that long to inspect, unless as per above, they find some rare and out of stock part they need to replace. Though at least they arent saying bring it in and weel do it while you have a cup of coffee. I'd be suspect that they would actually do anything in that time. At least having it for tree days you would expect they are going to crack it open and have a good look as to what the issue is.

As for the comparisons with other marques, its all a bit pointless. I went on 4wd and practicality, plus its quick. I didn't look to see which was quicker, nor did I review which cars were better for reliability, depreciation or warranty claims etc. I went on what I wanted a car for. Ive had sh*t box cars that I loved, and perfectly good cars that I didn't really enjoy. An awful lot is to do with the relationship you have with the dealer IMHO.

Im hoping that the 4wd will serve me better in the wet and slipy weather than a RWD would. Ive seen enough BMW's stuck in an inch of snow to know they aren't great, but a lot of that is often down to the bit of meat between the pedals and the steering wheel not having a clue how to drive in snow. Though I do, and Ive had enough experience driving in it to know that a 560+hp RWD car is not going to be the best driving experience in the winter. I'm also not expecting the simple addition of quattro to turn a 560+bhp car into something as capable in the winter as my Range Rover or a Discovery for example. I would still like the option of turning to something like that if we get a fair bit of the white stuff.

Ive got two small kids that need to be put in car seats, and Im keeping them rear facing for a good while, so an M6 is out, I also often tend to carry bulky items around (includng pushchairs), more often than I realised when I got my first saloon, so that ruled out a saloon.

So in summing up, I couldn't give two knobs of goat turd whether an M5, M6, E63 or whatever is slightly faster off the line, or has better quality stitching of the leather or whatever other trivial rubbish gets slung around, there is no better car for my requirements thats available in the UK than an RS6.

If its flat out speed and performance Im after, I'll simply get something else. Like a couple of year old Nissan GTR which would spank the lot round a track or from the lights, and cost half as much.

Picturing it & chuckling away as no such issue for me this morning, however not sure i was out in quite 2cm but certainly a full covering/dusting, but either way no dramas or traumas on the inclines & non treated roads all around me. Perhaps the BMW & Merc drivers you refer to were unskilled in such conditions, but believe me the car probably had little to do with it. Having owned AWD/FWD & RWD cars, it's driver ability & sensibility that counts & not how many driven wheels. The only 2 cars i've ever had issue with in snow were a FFRR (even i thought that was odd) & an R35 GT-R.

Anyhow, i'm glad you made it through the treacherous conditions in one piece

At least we can all agree, these are all fantastic cars, all with their flaws and benefits. The nut behind the wheel has a major part to play even more so in challenging conditions. Unfortunately I am one of the" throw enough power at it it is bound to move" brigade hence the Quattro to Stop me looking too foolish! I know better but my feet seem to have ideas of their own sometimes!

That made me chuckle. I remember vividly my R35 GT-R getting stuck in the snow right in front of my house (much to the amusement of my neighbours). The more 'power' i deployed the worse the situation became. I recall then abandoning my car whilst smacking the rear spoiler with my fist & hurling obscenities at it, needless to say this did't help my situation but did fuel my neighbours amusement.

Hoping never to repeat this (ever).

OK so the oil leak was caused by a faulty seal between the diff and the gear box. Did not need gearbox/engine removal just gearbox/diff split so only 2 days work.
Whilst the car was there they checked the cars onboard computer and found that it had decided that:
1) the mechanism on the MMI screen was juddering - so they replaced it
2) there was something wrong with the front tweeters - so they replaced them
3) there was something wrong with the near side wing mirror indicator - so they replaced it
I hadn't noticed any of this - but there you go
