Unhappy Sudden engine failure at busy intersection

I had the unfortunate experience of a sudden engine failure at a busy intersection.

My 2006 B200, with just 45,000kms had been driving just fine but shuddered and stopped at the lights.
The engine then failed to start and the car was stuck in the middle of the road!

It turns out the fuel pump has failed for goodness knows what reason, and now costs NZD$1,800 to fix!

Just a warning to be aware of. I've only had the car about 3 months and am now having seconds thoughts about my Benz purchase because of this safety issue and sudden engine failure.

My previous car (Nissan) has 140,000+ kms and has never had any such issues.

You cite a sudden engine failure. That's quite a dramatic description for a fuel pump failure. Usually we refer to an engine failure as pistons, valves, timing chain, etc.

$1250 U.S. dollars to fix a fuel pump? Someone is holding you up. Before I replaced the fuel pump, I would replace the relay first. How disheartening it would be to find that replacement of fuel pump was unnecessary because the relay was bad. Here's the video of the relay replacement:

Fuel pump failure

Thanks for your comment.

Yes, when I wrote engine failure I was thinking more literally of the engine failing to start. Sorry I'm not sure of the technical nuances of the failed engine (fuel pump vs other parts etc..)

I had to get the car towed to the local Mercedes service center (only one in town)

They quoted that amount for the repair (incl. diagnostics and labour)
It does seems quite expensive to me.

I wondered about the fuel pump relay too. I asked them about the relay and they said the relay was fine and that is was a fuel pump fault.

They said when they replace the fuel pump they replace the relay too, so it comes as a set.

Currently the car is in their workshop, so I need to wait for them to do the repairs.

I had another issue with the car a month ago that cost another $1,000 to fix and that was just a broken rear passenger door handle! ( http://www.benzworld.org/forums/w245...le-broken.html )

Not liking the maintenance requirements of the car so far, after 3 months ownership.

At this stage, seems I just need to wait for the repairs to be completed (again).
