F30 Timing change problem

Hi guys.

I have a 320d 3 series Sport F30 N47 Engine. The car is only
19 months old 11,000 miles and the timing chain has began to rattle.

BMW are going to replace it as under warranty but been told it's a very big job.

Just asking really has anyone else had this problem, and what is involved in repairing/ changing the chain. Also this dosent really seem to inspire confidence of purchasing future BMW cars with such a major fault when still so new.

I will write to BMW explaining my dissatisfaction.

Oh no, that is terrible. You must be super frustrated. Good to hear BMW is taking care of you. Have you asked about getting an entirely new car?

Hi.
No I haven't really thought about asking for a new car as it is 19 months old, and the chain is only rattling, hasn't broken or damaged the engine.

Do you think I should? Don't really think I will get much joy.

It sounds like its similar to the problems a number of BMW engines get. The S54, M62, and S62 all wear through their timing guides, presumably due to improper materials. Timing chains and guides are already a pain to replace in most engines.. But BMW decided to get creative with the N47/57 and put the chain in the back of the engine instead of the front -- that's why it's such an involved job on the N47

It's booked in for the 28th of April. BMW say it's about 4-5 days work as it's such a critical component and they need to test it thoroughly after the work is complete. I have sent a letter to BMW (Uk) stating my disappointment and will report back if I ever hear anything back.

Timing chain and tensioner have now been replaced by the dealership. 5 days work in total.
All running nice and quiet now.

I've had a response from BMW Uk regarding my letter of complaint about this matter. They are looking to extend the warranty on the car once the 3 year warranty finishes as a goodwill gesture.
