Oil pump problem hits UK M5, M6


UPDATE: Since publishing our story on BMW North America advising F10 M5 and F12/F13 M6 owners not to drive their cars, following the discovery of a fault with the oil pump that could lead to ‘severe engine damage’, we have heard that as a result of further internal investigations, BMW has now discovered that 19 British cars have the same potentially defective oil pump. BMW UK had initially said the problem did not affect UK cars.

On Friday (21 September) BMW US dealers were sent a technical bulletin saying that owners of 2013 model year F10 M5 and F12/F13 M6 cars built between July and September 2012 were being contacted as part of a recall, and warned not to drive their cars until the problem is fixed.

The fault stopped deliveries of S63TU V8 turbo BMW M5 and M6 in the US until the repair has been completed. The issue was characterised as serious enough to potentially cause the engine to suddenly lose oil pressure.

The fault in the oil pump was picked up by BMW’s routine quality checks. Repair is simple: swap the faulty oil pump for a correctly manufactured one. There have been no reported cases of engine failure as a result of the fault.

‘We are about to start the process of contacting owners,’ said a BMW UK spokesman. The work will be carried out under warranty as part of BMW's usual car recall procedures.

    - Although the design of the interior is very attractive, some of the materials used are very cheap and nasty. The plastic on the sides of the centre console is hard and scratchy, and the plastic around the climate control and stereo controls wouldn't be out of place in an 80's Peugeot. As in, you push it with your finger, and the whole thing creaks and moves. The silver plastic "aluminium" trim around the gear lever and on the gearknob itself is also marked already.

    - At 12,000 miles it has already lost its tight, "new" feel. There are various intermittent buzzes and squeaks from the trim.
    This is most definately true. My place of work makes interior parts for OEM's, and some of that is for a Teir 1 supplier of BMW, the adherence to drawings is almost non existent now. If you can take cost out of the finished part the spec/drawing will be adjusted to suit.

    For the bigger OEM's there are numerous off the shelf systems from Dow, Huntsman etc.. that are sold on cost. More filler they can get in these systems the more margin there is for them.

    Both the major German brands, Mercedes and BMW twenty years ago made a determined and successful entry into the volume car sector. Very successful judging by their sheer numbers on UK roads. Certainly BMWs more numerous than Fords and Vauxhalls locally.

    In so doing, is it mere coincidence that their previously held worthy quality and prestige status has suffered and been tarnished more than a tad in recent years?

    I always pick the brains of my friendly MoT tester when i have my cars tested. During the past decade or so, some of the stuff my MoT tester has described about the quality of various German and Japanese cars I found surprising, no, astonishing when he first told me. Not now.

    There again, there was a time when he had the mindset of "All Rovers do that"... smile Two decades of testing my own and my family's cars has changed that mindset for a good few years now. You can teach an old dog new tricks... smile

    HPFP on 335 and 535
    It's a lot more than just HPFP.
    I only wrote this as it's the most prominent/talked about one.

    Shame really, cause 335 could have been such a brilliant car.
    At the time of purchase I was wondering why my 330 was more expensive than quite a few 335i...
    Which engine do you have, N53 or N52?
    N52B30A
    Good job - I feared you had the N53.
