The second is the 4-cylinder, normally aspirated and turbocharged petrol N12, N14, and later N16, N18 engine that was installed in the MINI Cooper and S models from 2006 to 2016.
Often, if the timing is allowed to jump too late, the exhaust valves will flex. Therefore, if the engine rattles after starting from cold, it is preferable to replace.
Due to damaged valve stem seals that allow engine oil to vacuum bypass into the cylinders, these engines are also vulnerable to excessive engine oil consumption. It is advised to replace the valve stem seals when the engine is disassembled to replace the timing chain. This will spare labor for this separate repair down the road. We have a unique tool that makes it possible to repair the valve stem seals without taking the cylinder head off.
The drive belt for the alternator may occasionally be cracked or worn out from aging. While this is being removed, it is advised that you replace it.
In some circumstances, we demand a labor deposit to reserve a timing chain replacement (often roughly 50% of the entire repair cost). This is because there have been so many appointments in the past that were cancelled or missed.
How much does a BMW timing belt repair cost?
Belts don’t cost a much by themselves. Since many pieces must be removed in order to reach the belt, labor is where the true expense lies. Your best chance is to shop about and compare prices, but be prepared to pay anything between $409 and $919. (including parts and labor)

Will BMW cover the timing chain cost?
Depending on the mileage of the car at the time of service, the reimbursement scheme offers between 40% and 100% of the cost of repairs. If the repairs were carried out at a BMW center, there is no cap on the repair reimbursement.
When was the timing chain problem with BMW?
Many BMW customers now have a major issue with premature timing chain breakdown, which is frequently discussed in BMW internet forums, mentioned on BBC Watchdog, and highlighted on other media websites.
A timing chain design issue seems to impact a variety of BMW diesel engines built between 2006 and 2015. The engine timing chain is exceedingly fragile; over time, it stretches and eventually snaps.
BMW timing chains have broken on a variety of 1, 3 and 5 Series models, most frequently the N47 diesel. In addition, we restore BMW petrol engines, M57 and N57 diesel engines, and BMW Minis.
The timing chain is at the back of the engine compartment and is not meant to be repaired.
When did BMW first encounter timing chain issues?
Dermot McNamara, a lawyer in Dublin, said: “Since there has been more media attention in this area, we have been bombarded with requests from clients and new clients, particularly in cases where BMW has refused to pay for the repairs or has only offered to pay for a minimal sum.”
Recently, Mr. McNamara filed a lawsuit against BMW for a diesel engine failure on behalf of a client, but the issue was ultimately resolved right there on the courthouse steps. He thought that this might indicate that there are perhaps more cases than people realize.
“It’s hard to know how many instances like that have progressed that far before being resolved at the last minute.”
The issue began with the development of BMW’s wildly popular 2.0-liter diesel engine family in 2007, which went by the internal code name of N47. Customers loved the engine, which was installed in variants of the 1, 3, and 5 Series as well as the X1 and X3 SUVs. This was in part due to the engine’s ability to combine remarkable fuel efficiency with low emissions. When the N47 engine was installed in the 5 Series saloon, the Irish government was rather embarrassed since it discovered that BMW’s pricey luxury saloon was in the low Category B tax band, which was ostensibly intended to cover small, reasonably priced family cars.
The purpose of BMW’s timing chain
So what distinguishes a timing chain from a timing belt? Both a timing chain and belt perform the same basic function. These mechanisms are created to maintain the relative position of the valves opening and closing to the position of the piston as the engine is running, regardless of whether you drive a Porsche, Mercedes Benz, or BMW with an internal timing chain, or an Audi or Volkswagen with an external timing belt. When a valve is opened at the incorrect time, it may come into contact with the piston and cause a catastrophic engine failure.
The piston will raise (building compression) and the valves will open precisely, allowing air and fuel to enter the combustion chamber and exhaust to depart in less than one thousandth of a second in an engine with perfectly timed ignition. When valves open or close prematurely or lately due to a timing issue, the piston will be driven into the valve, most frequently bending the valve and possibly punching a hole in the piston crown, rendering the engine worthless. These fixes could cost as little as $4,000 to $5,000 or, depending on the engine, much more.
An internal timing chain is used by brands including Porsche, BMW, and Mercedes-Benz. These chains are stronger and less prone to break on their own. The same outcome is more frequently experienced when other chain-holding components, including chain tensioners and chain guides, fail. Check engine lights and a rattling sound, which is typically heard while starting an engine, are early warning indicators of a breakdown.
Initially using timing chains, Audi and Volkswagen switched to an external timing belt in the 1980s, 1990s, and the majority of the 2000s (now returning to chain drive systems). The timing belt is simpler to inspect and replace than the timing chain. Timing belt replacement often costs between $700 and $900, which is significantly less than timing chain replacement. On most models, this cost also includes the water pump. The external timing belt’s drawback is that, like all belts, it eventually wears out and needs to be replaced. Timing belts should typically be changed every 80,000 miles, or every five years. Each time they are serviced or at least once a year, these should be visually inspected.

Is timing chain repair worthwhile?
Timing chains do not require routine replacement, but timing belts do. The timing chain shouldn’t need to be changed unless it has been harmed, overworked, or otherwise compromised. Your car will most likely experience one or more faults if there is a timing chain issue.
A broken timing chain will show the symptoms listed below:
- The timing chain has noise.
- The check engine light is on.
- Misfiring engines and sluggishness
- The engine shakes or rattles while it is idling.
- The vehicle won’t start
You might hear noise coming from the area where the timing chain cover resides. This noise is frequently the result of a loose timing chain, which may be brought on by a broken timing chain tensioner, guide, or other issues. More serious issues will arise if you ignore the early warning signs, so be sure to check the timing chain as soon as you hear a noise coming from where it is mounted.
