Which BMW Engines Have Timing Chain Issues?

-

When you buy a BMW, I'm sure you’re expecting a smooth ride, not a bill the size of a small mortgage. But for some owners, timing chain trouble has turned that dream into a bit of a nightmare. You're not alone if you’ve wondered whether your BMW engine could be at risk.

We are always asked about BMW timing chain issues at MT Auto Parts. So, we thought it was high time we clarified things with a clear guide on which engines are affected, how to spot the signs, and your options if your car’s in the danger zone.

What’s the Deal with BMW Timing Chains?

Timing chains are supposed to be the “fit and forget” part of your engine. Unlike timing belts, they’re designed to last the engine's lifetime. Or at least, they should. Unfortunately, that hasn’t always been the case, especially with some specific BMW engine models.

When timing chains start to fail, it’s not just an annoying rattle. It can lead to complete engine failure if left for too long. And replacing an engine isn’t exactly pocket change, is it? BMW engines usually face this issue.

The BMW N47 Engine 

Let’s start with the big one: the N47 engine. If your BMW was built between 2007 and 2011 and runs on diesel, there’s a decent chance you have this engine under the bonnet.

This four-cylinder diesel unit powers popular models like:

  • BMW 1 Series (E81, E87)

  • BMW 3 Series (E90, E91)

  • BMW 5 Series (E60)

  • BMW X1 and X3

Now, what makes the BMW timing chain issues particularly unpleasant is that the chain sits at the back of the BMW engine. This means replacing it isn't just a Saturday afternoon job. You need to carry the engine out to fix it, which is costly and time-consuming.

If you hear metallic rattling from the rear of the engine, especially on cold starts, get it checked immediately.

The BMW N63 Engine 

The BMW N63 engine, a twin-turbocharged V8 found in models like the 550i, 750i, and X5/X6, has had its fair share of drama.

It was introduced around 2008 and has been subject to several technical service bulletins due to issues ranging from oil consumption to, you guessed it, BMW timing chain issues.

In fact, BMW launched a voluntary Customer Care Package back in the day to address problems like:

  • Excessive oil consumption

  • Valve stem seal leaks

  • Timing chain stretch

While that campaign has long since ended, the problems haven’t. So, if you're driving an N63-powered beast, it’s worth keeping a close ear on things. MT Auto Parts also offers used, OEM BMW N63, S63, N55, B58, N57, B57 and other BMW engine options for far less than dealership prices. If you are looking to buy a BMW engine, MT Auto Parts is a reputable seller to check!

How to Spot Timing Chain Problems

If your BMW engine is developing timing chain issues, it’ll usually start with some subtle (and not-so-subtle) signs:

  • Rattling noise on cold start

  • Engine warning lights

  • Rough idling or poor performance

  • Delayed throttle response

Don’t ignore these symptoms. Once that chain jumps a tooth or breaks, it can lead to an engine catastrophe.

What Can You Do About It?

If you suspect something’s off, don’t wait. Get a diagnostic check. It might be a simpler fix if the chain is stretched but hasn’t snapped.
