You won't find links to BMW QE's on the Internet.The only way to tell if you're car is covered is to contact you're local dealer and they will check the vin number.

That's the one

[IanS100]

I'm just below their magic 75k kilometres ie:

below 75,000 km, only replace the chain tensioner
above 75,000 km, you must also check the timing chain

................. so I think I'll wait till I get a recall or it needs to go in for service, the chain isn't making a noise so I don't see it as being urgent for a couple months motoring, but thanks for the heads-up!

[Leah1]

If bmw checked the tensioner then some years down the line the chain started to make a noise would they then be liable? How does that scanario work? Are they now showing they are liable?

[jammy78]

So does the tensioner have to be replaced.... I don't want the dealer saying, there's nothing wrong?

Also, what is the sound I should be heading out for?

As they say..... knowledge is power when it comes to some dealers!

[Leah1]

Go on YouTube put in n47 timing chain plenty of examples,
Yes sound like the tensioner needs to be replaced at the minimum. Reading that bulletin are they Saying the tensioner is what's causing the chain to wear, I thought the problem was sharp sprockets ?

[Rhino.]

I called my local BMW today and having given them my reg they said there was nothing showing at all. A bit confused to be honest :/

[Leah1]

What year is your car?

2011 mate, it's the 318d.

[Leah1]

Unless they have revised the parts on that year, there were rumours they had sorted the problem on the younger cars

This is a copy of the puma report from another thread, it seems there was a modification in Jan 2009, and then another on in March 2011.

PUMA 13588845-03 incidence recorded by BMW and its repair: http://www.puma-index.de/Lists/PUMA/AllItems.aspx

Diligence-number Item
43863106-03 N47, N47S, N47T, rustling sound in the engine, timing chain rubs.

Approval date (day.month.year) Status Organization
Approved 14.12.11 Germany, automobiles

Vehicles affected
E Series Motor Body
E60 E61 E81 E82 E83 N47 N47DKO N47S N47T E61 E60 E81 E82 E83 N47 N47S N47T N47DKO
E84 E87 E88 E90 E91 E87 E84 E88 E90 E91
E92 E93 F10 F11 F25 E93 E92 F10 F11 F25

Feedback Comment production interval Feedback
(From / to) on the production interval diligence (day.month.year) to (day.month.year)
/ 01.03.11 / 01.03.11

Complaint
Sound of friction drag on the engine from about 1500 rpm, which is visible from the inside.
The noise can be perceived in area of the gearbox housing and the oil pan.

Cause
Excessively sharp edges on the sprockets, the chain does not flow evenly over the guides.

Measures
We must distinguish two cases:

Case 1:

For engines N47, N47DKO, N47S, interval from 01.03.2007 to production 05.01.2009.

In case of customer complaint must change the following parts:
(See Annexes, Figures 1 to 7.) - Nov. 21 7803479 Sutitución the crankshaft bearings.

Caution: Use only crankshafts with a production date back to 5. 1. 1. 2009 2009
The production date is printed on crankshaft sprocket (see page 2 of the Annex)

Meaning of the figures:
The first two indicate the assembly line.
The 6 following year (two digits), month, day.
Last 5 indicate the reference number of the crankshaft.
Thus, the crankshaft shown on page 2 of the annex was built on October 21, 2009.
41 -11 7,797,896 chain oil pump.
11 31 8 506 652 Timing Chain bottom.
13 52 7 797 906 sprocket for driving the high pressure pump.
11 27 7 800 523 sprocket (intermediate for balance shafts).
11 8,510,014 31 Supply Chain superior.
-11 7,797,899 31 Timing Chain Guide above.
-13 7,797,904 52 Timing Chain Guide below.

Note: Adjusting the intermediate gear shafts accurately balanced according to workshop manual. In case this intermediate sprocket and the balance shafts are not sufficiently fit, the motor can still giving rise to noise despite the new crankshaft.

See November 21 workshop manual 500 "crankshaft replacement."

Note: In the case of vehicles to which a previous repair and they replaced the crankshaft:
Proceed with these vehicles as detailed in "Case 2".

Case 2:

N47 engine, N47DKO, N47S, N47T production interval 05.01.2009 - 01.03.2011

In case of customer complaint replace the following parts:
(See Appendix, Art 8 to 10)
-11 8,506,652 31 Supply Chain bottom.
- 13 52 7 797 906 sprocket high pressure pump.
- 11 31 8 510 014 Supply Chain superior.
-11 7,797,899 31 Timing Chain Guide above.
-13 7,797,904 52 Timing Chain Guide below.

Note: There is no need to release the binding thread of the intermediate toothed wheel balancer shafts.

Note: As of March 2011 there are new guidelines. These guidelines do not bring reinforcing ribs.

(See Appendix, pp. 7 and 10.)
In this way the inner surface of the guides is smooth throughout its length and the timing chain runs easily on them.
They have not changed the references.

Note: During the repair make sure guides are mounted without lateral veins (in the Annex, Art 7 and 10.)

Attention:
No repairs are allowed in vehicles with production date after 03/2011 and vehicles in which all existing measures have already been made. The sound now is the moment, the normal state of this world! No risk of broken chain!

Not allowed engine change because of this claim!

Claim
Location of the defect: Defect Type: Circumstances of default:
Guide part incorrect

Crank Noise

Distribution

Worn crankshaft

Listening to videos on youtube although my car is loud and sounds like a tractor its quiet compared to most of them, see what they say in a few weeks when it goes in

You're welcome

Maybe the QE only applies to cars between 07 and 09?

Part of the reason I bought my car was I knew it had the later version of the N47 which shouldn't be effected
