clicking noise from the engine (128i)

[cks0213]

When I start my car there is a constant clicking noise from the engine.
When I give it some gas the clicking gets faster, and back to the usual clicking sound when no gas is given.
Anyone have the same problem?

[m_thompson]

Sounds like you need to have your dealer bleed the air from the lifters.

[cks0213]

so it is something that I should take it in for?

What is this??? Never heard of it. Are you talking about hydraulic valve lifters?

[cks0213]

any ideas?

[White1]

I had it happen to my car, i took it in, and my SA had the bleed done, and the noise went away, but eventually it comes back. It is caused by a small missdesign in the head, but is in fact harmless. It tends to happen when driver keeps engine at low RPMs for extended periods (in city driving) especially. If you take it for a good rip on the highway, and keep the RPMs reasonably high, the noise will dissapear for a while afterwards.
It will come back again tho, so just repeat the rip.

Yup. Apparently there is a design issue in the lifters that was fixed in the current models. The dealer can run the engine through a lifter bleed cycle to make them quiet again. Sometimes the fix is permanent, sometimes a blast on the highway will fix it, sometimes the lifters need to be replaced. The bleed cycle was a permanent fix on my wife's 328xi.

If your car is still under warranty you should get the dealer to fix it. If not, try a blast on the highway.

[cks0213]

Thanks guys.
Feels so good to know i'm not alone.

[Yuzi]

happened to me b4 ~ just rip it on the hwy then it's gone

[SlickShift]

You're not driving the car hard enough...seriously. That's the only reason the lifter would be clicking.

[mantissss]

this happens in the N52 as well, in fact its very common in X5's because the people who buy those cars typically drive relaxed...all that is need is to occasionally or how ever often you give that motor some throttle (act like you're 16 again and there are some hot girls on the street corner...if you get what im sayin)

Ticking Noise SBSI B 11 09 07 -N52 Engine HVA System
________________________________________
The ticking noise is a known problem with the N52 (3.0L) engine fitted to e90 series vehicle. I have the problem with my 3 series wagon which now has 68K miles. I only get the problem if I travel short journey's, most of my driving is 30 mile min. so I don't here the noise very often. The real fix is to change the cylinder head, my dealer said because I reported it during the warranty period they would repair it if the SB fix does not work, so far it does.

This Service Information bulletin supersedes SI 11 09 07 dated April 2008.

SUBJECT
Intermittent Hydraulic Valve Adjuster (HVA): "Ticking" or "Rattling" Noises


MODEL
All E82, E83, E85, E86, E88, E60, E61, E70, E90, E91, E92, and E93 with the N51, N52 or N52K engines


SITUATION
An occasional ticking or rattling noise from the HVA elements may occur during cold engine starts or frequent short-distance driving.

CAUSE
In these situations, the HVA elements may not yet have been supplied with sufficient amounts of air-free oil. This condition will not cause any damage to the engine, and usually remedies itself with a longer driving distance or operating times at full operating temperature.

CORRECTION
In the event of a customer complaint, please perform the following the HVA bleeding procedure.

PROCEDURE
Important notes:

The bleed time may take anywhere from between two minutes and (in rare cases) to a maximum of 30 minutes. This procedure is to be performed on a level surface with the vehicle stationary, and in a properly ventilated area.

Procedure preconditions:

Engine oil level correct – neither underfilled nor overfilled

Engine running at operating temperature

Bring the engine up to an operating speed (no load) of 2000-3000 rpm and maintain this condition for three minutes (bleeding procedure).

Let the engine idle for 15-30 seconds and reevaluate whether the noise is still present or not.

Engine quiet – procedure is finished.

Engine noise is still present – repeat the procedure; perform steps #1 and #2 up to a maximum of 5 times.

Only if the noise remains after performing the bleeding procedure 5 times: proceed by performing the procedure for a final time, also at an engine operating speed of 2000-3000 rpm, but for a total time duration of 15 minutes.

SUBJECT
Intermittent Hydraulic Valve Adjuster (HVA) Noise

MODEL
All E82, E83, E88, E85, E86, E60, E61, E70, E90, E91, E92 and E93 vehicles with N51, N52 or N52K engines produced approximately up to November 31st 2008; refer to cylinder head casting identification attachment.


SITUATION
An occasional ticking or rattling noise from the camshaft hydraulic valve lifters (HVA) may occur during cold engine starts, due to frequent short-distance driving, or the noise may occur for an extended period of time even though the engine is at operating temperature.

Improved parts were phased into production beginning on 10/1/2008 and fully implemented on November 31st 2008.

CORRECTION
Do not perform the bleeding procedure that was previously provided in SI B11 09 07 which has now been deleted.

All vehicles produced between 10/1/2008 and 11/31/2008 must have each vehicle's cylinder head casting number identified before hydraulic valve lifters (HVA) replacement, due to staggered implementation. Refer to the attachment for the casting number location. Vehicles produced after 11/31/2008 have already been fitted with improved parts. Vehicles produced prior to 10/1/2008 will require the new parts.

Improved Casting Numbers

N51 (B30)
7588277.01

N52 (B30)
7588273.01

N52K (B30)

According to the Report of the House of Representatives which accompanied the law (House Report No. 93-1197, 93d Cong 2d Sess.) the Magnuson-Moss act was enacted by Congress in response to the widespread misuse by merchants of express warranties and disclaimers. The legislative history indicates that the purpose of the Act is to make warranties on consumer products more readily understood and enforceable and to provide the Federal Trade Commission with means to better protect consumers.[1]

The statute is remedial in nature and is intended to protect consumers from deceptive warranty practices. Consumer products are not required to have warranties, but if one is given, it must comply with the Magnuson-Moss Act.

[edit] Definitions used
The Magnuson-Moss Act contains many definitions:

A "consumer" is a buyer of consumer goods for personal use. A buyer of consumer products for resale is not a consumer.
A "supplier" is any person engaged in the business of making a consumer product directly or indirectly available to consumers.
A "warrantor" is any supplier or other person who gives or offers a written warranty or who has some obligation under an implied warranty.
A "consumer product" is generally any tangible personal property for sale and that is normally used for personal, family, or household purposes. It is important to note that the determination whether a good is a consumer product requires a factual finding, on a case-by-case basis. Najran Co. for General Contracting and Trading v. Fleetwood Enterprises, Inc., 659 F. Supp. 1081 (S.D. Ga. 1986).
A "written warranty" (also called an express warranty) is any written promise made in connection with the sale of a consumer product by a supplier to a consumer that relates to the material and/or workmanship and that affirms that the product is defect-free or will meet a certain standard of performance over a specified time.
An "implied warranty" is defined in state law. The Magnuson-Moss Act simply provides limitations on disclaimers and provides a remedy for their violation.
Designations:
A "full warranty" is one that meets the federal minimum standards for a warranty. Such warranties must be "conspicuously designated" as full warranties. If each of the following five statements is true about your warranty's terms and conditions, it is a "full" warranty:
You do not limit the duration of implied warranties.
You provide warranty service to anyone who owns the product during the warranty period; that is, you do not limit coverage to first purchasers.
You provide warranty service free of charge, including such costs as returning the product or removing and reinstalling the product when necessary.
You provide, at the consumer's choice, either a replacement or a full refund if, after a reasonable number of tries, you are unable to repair the product.
You do not require consumers to perform any duty as a precondition for receiving service, except notifying you that service is needed, unless you can demonstrate that the duty is reasonable.
A "limited warranty" is one that does not meet the federal minimums. Such warranties must be "conspicuously designated" as limited warranties.
A "multiple warranty" is part full and part limited.
A "service contract" is different from a warranty because service contracts do not affirm the quality or workmanship of a consumer product. A service contract is a written instrument in which a supplier agrees to perform, over a fixed period of time or for a specified duration, services relating to the maintenance or repair, or both, of a consumer product. Agreements that meet the statutory definition of service contracts, but are sold and regulated under state law as contracts of insurance, do not come under the Act's provisions.
[edit] Requirements
The Act provides that any warrantor warranting a consumer product to a consumer by means of a written warranty must disclose, fully and conspicuously, in simple and readily understood language, the terms and conditions of the warranty to the extent required by rules of the Federal Trade Commission. The FTC has enacted regulations governing the disclosure of written consumer product warranty terms and conditions on consumer products actually costing the consumer more than $15. The Rules can be found at 16 C.F.R. Part 700.

Under the terms of the Act, ambiguous statements in a warranty are construed against the drafter of the warranty.

Likewise, service contracts must fully, clearly, and conspicuously disclose their terms and conditions in simple and readily understood language.

Warrantors cannot require that only branded parts be used with the product in order to retain the warranty.[2] This is commonly referred to as the "tie-in sales" provisions[3], and is frequently mentioned in the context of third-party computer parts, such as memory and hard drives.

[edit] Full Warranty Requirements
Under a full warranty, in the case of a defect, malfunction, or failure to conform with the written warranty, the warrantor:

must, as a minimum, remedy the consumer product within a reasonable time and without charge;
may not impose any limitation on the duration of any implied warranty on the product;
may not exclude or limit consequential damages for a breach of any written or implied warranty on the product, unless the exclusion or limitation conspicuously appears on the face of the warranty; and
if the product, or a component part, contains a defect or malfunction, must permit the consumer to elect either a refund or replacement without charge, after a reasonable number of repair attempts.
In addition, the warrantor may not impose any duty, other than notification, upon any consumer, as a condition of securing the repair of any consumer product that malfunctions, is defective, or does not conform to the written warranty. However, the warrantor may require consumers to return a defective item to its place of purchase for repair.

The Magnuson-Moss Warranty Act (P.L. 93-637) is a United States federal law (15 U.S.C. § 2301 et seq.). Enacted in 1975, it is the federal statute that governs warranties on consumer products.

The Act was sponsored by Senator Warren G. Magnuson of Washington and Congressman John E. Moss of California, both Democrats.

Anyone have the same problem?

I got mine fixed under warranty. It's the lifter in your engine

I hate to revive this old thread, but I am having the same problem as described above. However, my car is out of warranty. Anyone have any idea on how much would it cost to fix this?

[m_thompson]

The final fix on my wife's 328xiT was a new cylinder head. The price on the warranty paperwork was around $6,000.
