Hello,

My 07 530xiT with 45k miles consistently sounds like a ticking sewing machine at startup. The noise goes away after some time.

I know it's the valve train but the dealer will not fix. they say, "its normal".



I had it in for service in January for the same issue. The work order says they replaced the exhaust lifters.
I've had it in 2 times after for the same issue and get the same reply, "it's normal".


Is it?
:dunno:


Thanks

I have had that sound on some cars,including my F-150 truck.

But not my 08 535i Sport. Don't think that is normal.

Lifters,and pull the head?

EDIT: Superceded by this:

September 2009

This Service Information bulletin supersedes SI B11 09 07 dated January 2009.

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)
7588271.01

A 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.

Did you see it in the service record?
I asked for one the first day I took it in for service.
They gave me a copy.

I owned the car when the work order says they were replaced.

"I had it in for service in January for the same issue. The work order says they replaced the exhaust lifters"

I saw on another site that someone had the same issue and the dealer finally replaced the head.
Is there any service info for that? SB or such?
