I believe this is what has failed after only 60,000 miles. I was sat in traffic wondering where the diesel car was only to find the noisy diesel engine was in fact mine. I did consider timing chain but having spoken to others it seems it may be the supercharger.

I was wondering what route most have taken in this situation. BMW will replace it as a special order (not likely before middle of May 2019 and £1,300 (not sure incl or exclusive but knowing BMW excluding VaT). I spoke to 1320 who said they had no recommendations for repairers/rebuliders.

Open to suggestions/recommendations.

Presumably though if the disconnection is only temporary and the engine is not allowed to get up to full operating temperature no damage will be done and will allow enough time to listen to the engine - ?? (I am only a tinkerer).

More importsntly though is has anyone successfully gone the supercharger refurbishment route?

Thought I would update this thread. The Supercharger went off for a refurbishment to GT Tuning in Blandford, Dorset and has been refitted but the engine is still noisy so I am getting the chain tensioner done.

GT Tuning were not the most communicative of people and despite their claimed three day turn around it was more like five. Arrived on a Monday and was sent back Saturday I think. I did want to ask them about their thoughts on it but they just said yes it could do with a refurb. So again at only 60,000 miles it may have been too early for a refurb. It came back with lots of blue gunge along the joins so I am not sure what that says about their work but we shall see. They did try and talk me into upgrades on pulleys but I told them I have a track car and was happy with what I got out of it on the road. So some GBP 600 lighter in the pocket I hope it was a beneficial move.

More to follow once the chain tensioner is sorted.
