Thank you, this is what I did when I purchased back in July last year and then renewed it at the beginning of the year.
Understood. I thought you meant an invoice for the warranty but you meant for the car.

No reason why the policy wouldn't be validated, that shouldn't be a problem.

As for the claim, fingers crossed for you that they don't find anything. If the car isn't modified or has missed any services then it should be OK but it would be good to hear about the outcome.

Having owned two S63 engined cars in different iterations and currently in an N63 TU3 X5 I must say I never had a single problem (touch wood). No doubt there are problems as with all samples of engines but not sure they are more frequent than any of the AMG or Porsche equivalents.

Oil change more frequent than the 30.000
Km ridiculous schedule and proper warming up and down will go a long way to prevent problems

P155flaps what car do you actually have an M5 or M6? LCI or pre LCI?

I have the the very early LCI M5. I think I read somewhere LCI had changes done on the engine

My one frequently needs a top up of oil, more during the harsh winter I noticed, 1 LITRE every 1k miles

That would normally qualify you for a new engine in Europe or at least some investigation under warranty... Think about it... You cannot drive from Calais to Milan and back without lugging at least a 2ltr bottle of oil in your boot...

The s63tu does seem to have the ability to randomly self destruct. Its the no prior warning that puts me off. I have a mate who runs a garage and they had one brought in on a trailer. It was seized, guy had only had it a few months.

The v10 seems so much more reliable in hindsight biggrin

Good point, BUT mine rarely goes beyond the M25smilesmilesmile

I have had the car for 5-6 years and have used the same dealer, if i complained I know they would look at it. But I ignored it as it runs very good and if it does go caput I have a annual warranty I pay for exactly for this reason. But even that means I will probably have to pay for some of the reapir the car I recon is worth between 20 - 23k MAX

2013 m6 pre lci.

In the 2k miles I’ve driven mine I’ve added 2 litres of oil so sounds the same…

Mine is fecking annoying since we do at least 3 Alps trips every year and I have to find the space for two cans of 1lt Shell 0w40 Twin Power or whatever it is called these days. It runs well too, but I am seriously thinking about asking our dealer to look into it. I was told, they change the oil, seal the sump/oil cap and then monitor the level. If you, let's say, use 1ltr/1000km, BMW most likely would authorise investigation/repairs/replacement under their warranty scheme...

Still waiting to hear. I’ve not been asked for any paper work at all other than the invoice / bank statement to prove what I paid for it.

As far as I can tell from reams of paperwork all present and correct.

Although early life after 1k mile run in service (which it had) some seem more than 12 months apart but it was on a service pack and had print outs from bmw to show how many miles / months left on each service item each time it went in, and oil always showed lots of miles / months left.

Also warranty claims since then (high pressure pump oil lines etc) all honoured as warranty print out.

Since service plan ended in 2016 every 12 months so should be fine.

Never had a clutch, engine or anything go in 25 years of driving so I am just unlucky on this one I guess. Typically probably most expensive engine of all the cars I’ve had!

Will update once I have an outcome to warranty claim / good will just so people aware how it plays out.

It’s had a diff oil change last service at 54k mikes so if it is honoured etc when they have engine out will get them to do a gearbox oil / filter change to and then it’s should be good.

Thanks mate, do update us, I think you will be ok. On a side note mine has been locked up at the dealers for the last 2 months. Comfort Acess Door handle playing up, the car was unlocking by itself. The door handle is on back order I have been told and they have no time frame. In the mean time they have given me a M440i which I have had for weeks now....

I wonder if any of the failures are caused by the oil pump drive chain being too loose? It’s manually tensioned and from the reports I’ve seen when checked seem to be too loose. I am going to check mine next oil change at 32000 miles and will report the findings on my readers thread.

The warranty doesn't restrict your claim to what it is worth today, so if you paid £30k for it however long ago and is and always has been mechanically standard (they can detect if the ecu has ever been mapped), then you are covered up to £30k.

I've got exactly the same problem with mine just now, started off with the comfort access not working from the driver's door handle, then progressed to the car immediately unlocking itself after you'd locked it. This problem was solved by walking away from the car till the key's out of the range where the comfort access works (only a couple of feet) and locking it, it then stays locked.

I'd get back in touch with the dealer you're using, mine got the new handle within 4 weeks, the only reason it's not fixed is because I had to cancel the last booking, it's going in at the beginning of next month.

On the other hand I expect you're enjoying the M440i biggrin

Same thing as mine, started off on the passenger side handle then progressed to the car immediately unlocking itself after you'd locked it. The door handle was ordered in December 2022, still waiting...back order I was told, in all fairness the dealership is great.

Regarding the M440i Gran Coupe, nice car, amazing Tech. You can't feel the sense of speed, even less though than the M5. xDRIVE is amazing even in this weather, day to day driving the m5 will be out of site on an urban road, however 60MPH Plus on a staright Road the 4 Series has zero chance against the M5.

Back in 2013 during my dealer days, I had to rebuild a 2010 F10 550i with the N63 due to excessive oil consumption (less than 500 miles to a litre of oil) and a rattle. The car sticks in my memory as it was a real base spec SE on the smallest wheels, chrome trim, beige leather and bugger all options!

After a PUMA case was submitted technical came back and said that no one had pulled one apart in the UK for this issue at the time so I had to completely strip it down and inspect and measure everything. I found the bores were worn out of spec (car had done about 30k miles) and some of the HVA's (hydraulic lifters) had collapsed.

The repair consisted of a new block and pistons, new oil pump and 32 HVA's. When the new parts finally arrived the oil pump was a superseded part number and the block design had changed slightly as the original block had 4 oil jets with twin outlests for cooling the underside of the pistons and the new block had 8 individual jets.

Fast forward and having left the dealer network and set up an indy, we have had a few F10 M5's and an E70 X5M in that have had spectacular bottom end engine failure but to be fair, the common denominator with all those is that they had been remapped.

We have rebuilt a few N63's in F1x Alpina B5's and 550is as well which have been high milers with oil leaks and smoking valve stem seals which have been ok internally.

I also cannot stress enough how bad circa 15k mile oil changes are.

Nah mate...

You are just scaremongering and drumming up business...

silly

Joking aside, there are some really strange engineering solutions/decisions on these engines. Their nickname - Lucifer - is quite appropriate... I am amazed that JLR is using the latest generation in their products. Two wrongs don't make one right!

Had email at COP today.

It looks like warranty will pay out (need to see that in writing as was implied but not clearly stated).

BMW offered £3k contribution (~8% value of claim).

So leaves me with a ~£10k bill.

I’ve gone back to see if BMW will up contribution.

I’ll mull over options once BMW come back.

This seems very odd to me personally. I done 28k miles in my m6 GC 2016 and I only ever topped it up once when it asked for it. It’s never needed it otherwise. I never hung around either! Ever

Hi - is your M5 back with you with a new engine? how did this one pan out? Did you have to pay?

Thanks
