[viewfinder]

Pls refer to this thread on US site bimmerpost.com. Is it a common problem for the ones in M'sia, and if yes do you managed to get fix under warranty?September 2009This Service Information bulletin supersedes SI B11 09 07 dated January 2009.SUBJECTIntermittent Hydraulic Valve Adjuster (HVA) Noise MODELAll 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. SITUATIONAn 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. CORRECTIONDo 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 NumbersN51 (B30)7588277.01N52 (B30)7588273.01N52K (B30)7588271.01A cylinder head casting number that does not match will require replacement of the 12 exhaust camshaft hydraulic valve lifters (HVA) as per Repair Instruction RA 11 33 050, Removing and installing/replacing all rocker arms. Only the exhaust camshaft and rocker arms have to be removed in order to replace the hydraulic valve lifters. Do not remove or replace any intake camshaft valve train components.PARTS INFORMATIONPart NumberDescriptionQuantity11 33 7 605 330Hydraulic Valve Lifter (HVA)12Refer to EPC for additional gaskets, seals and bolts, as required by the Repair Instructions.WARRANTY INFORMATIONCovered under the terms of the BMW New Vehicle Limited Warranty, or the Certified Pre-Owned program.Please refer to the latest KSD for the applicable Main or Associated labor allowance for the specific model.Defect Code:11 33 93 39 00Labor Operation:Labor Allowanceescription:00 58 248 Refer to KSDReplace exhaust camshaft hydraulic valve lifters (HVA)*Main Workor00 58 827Refer to KSDReplace exhaust camshaft hydraulic valve lifters (HVA)

...due to frequent short-distance driving,...

Damn! have to move office!

BMW engines are performance engines and are not happy puttering around daily below 1,500 rpm on the office run. My office run is also short, but I try to floor the pedal once a day and take it up to 5-6,000 rpm to ensure the oil pump floods the top-end. At low RPM, no oil gets up there.

I guess short run in US would typically mean a trip to the grocery store within 5-10miles radius.

Hope the oil pump design has pumped enough oil up there with pedal to the metal during short run.

 

[Schwepps]

Better than no oil at all. Keep your eye on the tachy in city driving: it always hovers at 1500rpm. Even if you push a bit, the gearbox shifts at 2000. Besides, I like to hear my engine scream with pleasure at least once a day. :wink:

Yeah city driving is boring.

Fortunately my short drive to work does allow rev'ing for a short stretch

The ticking noise found on YouTube... it's LOUD.

Edit : thanks
