March 2022
Changes to this procedure are highlighted in yellow.

Do not drain and measure the engine oil. Follow the applicable instructions to use the electronic oil

level measurement.

Do not reprogram the vehicle.

Do not repair any engine oil leaks prior to starting the oil consumption test described below.

1. The engine oil must be measured using the electronic measurement test plan called “Motor Oil Quantity”

found in ISTA/D.

Test Plan Path:

Select “Vehicle management”

Select “Powertrain”

Select “Engine electronics, quality control valve (MSV)

Select “Engine oil”

Select “ABL Motor oil quantity”

Select “Display”

Follow the onscreen prompts. The test plan will measure the engine oil in 100 ml increments.

Top the engine oil accordingly and perform the test plan a second time (after topping) to ensure the

proper full engine oil level is reached.

The vehicle must be driven by the customer roughly 750 to 1,000 miles or until the next low engine oil

message appears (whichever comes first). After the customer returns the engine oil must be measured

again using the electronic measurement test plan called “Motor Oil Quantity” found in ISTA/D.

If the oil consumption is not greater than 1 liter per 750 miles, then top the engine oil and return the vehicle

to the customer.

OR

If the engine oil consumption is greater than 1 liter per 750 miles, then proceed to step 2.

For additional information on oil consumption refer to B11 03 13.

2. Inspect or measure the following 4 items in order. Note the inspection results on the attached

“B01_21_18_N63TU1_Oil_Consumption_Checklist.”

B01_01_22_N63TU1_Oil_Consumption_Instructions V2.0
March 2022
Vehicles that require an oil consumption test, have passed the oil consumption test, or do not require any

repairs do not need authorization.

IMPORTANT!

If the engine is leaking engine oil, the oil leak must be an active major engine oil leak, not seepage or

wetness.

GENERAL NOTES REGARDING ENGINE OIL LEAKS:

“Oil Leaks” are being defined as clearly visible oil presence (like oil drops) at the engine components

(e.g. area of oil pan, front cover, etc.), and in their vicinity. Also, a large visible oil stains (or oil

accumulation) on the underbody panels are indication of oil leaks, causing a substantial oil capacity

loss.

The black (dirt stained) “wetness” marks on the engine components, DO NOT qualify as oil leaks.

3. Inspect the front engine cover for engine oil leakage.

If the front timing cover is not leaking. Go to

step 4.

If the front timing cover is leaking. Go to step

Once the bore scope has gone under the

plastic reservoir tab then the engine valley

drain hole (1) and surrounding area can be

clearly inspected.

The dark material at the bottom of the photo

is dust and dirt. This material appears to be

reflective, but it is dry.

Engine valley drain hole (1)

Plastic vacuum reservoir (2)
If engine oil is found in the valley area, then the root cause of the engine oil leak resides in the components

on top of the engine i.e., turbocharger oil line cover, turbo charger, etc. Further basic diagnosis will be

needed to find the root cause this engine oil leak. Do not remove the transmission from the vehicle. Go to

Step 7.

If NO engine oil residue is found at the engine valley drain hole, but an original visual inspection indicated

leak in the bell housing area, the root cause of the engine leak resides in the rear main seal and rear engine

cover. Do not remove transmission from the vehicle. Go to step 7.

If NO engine oil residue is found at the engine valley drain hole, then the root cause of the engine oil leak will

be related to the original visual inspection of front cover, or oil pan. Go to step 12.

Using the borescope, provide a picture of the engine valley drain hole regardless if oil is present or not.

7. Preform the compression test.

Test Plan Path:

Select “Vehicle management”

Select “Service functions”

Select “Powertrain”

Select “Engine Electronics quality control (MSV)”

Select “Compression test”

The compression test plan and the compression test repair instructions will be shown on the screen.

Review the compression test repair instruction to become more familiar with the tools and the

procedure before starting the compression test plan.

3.

4.

5.

6.
For reference the compression test procedure instructions can also be found in Repair Instruction 11 00 039

“Checking compression of all cylinders”.

The compression test should be performed after the engine has reached operating temperature. When

performing the test count the rotations of the engine crankshaft and apply the same rotations to each cylinder

compression test. The industry standard is 4 rotations per cylinder.

When comparing the values of all cylinders the compression results should not vary by more than 2.5 bar or

36.25 psi. If the difference is greater than 2.5 bar or 36.25 psi, then proceed to step 11.

The test plan will record the measurements, but you will have to determine if they are within specification or

not.

If the BMW special tools are not available at the dealer then a manual gauge procedure can be substituted,

record all values in the oil consumption checklist. Use the limit values listed above to determine if the values

are within specification.

If the engine passes the compression test, then proceed to step 8.

Consumption FAQ”.

Engine Repairs and Replacements:

Replacement engine assemblies are NOT pre-filled with engine oil.

After replacing an engine with a new or remanufactured engine assembly, the engine oil level must be

verified as outlined in the procedure below first, before starting the engine for the first time.

If the replacement engine is started to determine electronically if the engine is filled with the appropriate

amount of engine oil, damage to the replacement engine can occur immediately.

The engine may have some residual engine oil from assembly, but this is not enough engine oil to properly

lubricate the engine to measure the engine oil level electronically when it is started for the first time.

Further, the electronic engine oil measurement is only operational when the engine is running at its full

operating temperature. Checking the engine oil without the engine running at operating temperature will lead to

an incorrect or incomplete measurement.

After replacing the engine or making engine repairs that require the replacement or removal of the engine

bearings, VANOS gears, camshafts, bed plate resealing, engine oil pump, engine oil filter housing, cylinder

head, engine oil cooler or anything that interrupts the engine oil supply circuit of the engine requires a short oil

pump and oil supply circuit priming procedure.

Refer to SI B11 02 20 for the detailed bleeding procedure.

After engine repair or replacement, pay attention to a proper installation of all engine ground

connections.

N63TU1 proper Ignition Harness Installation and Ground Connections: Any consequential damage to DME,

alternator, or QLT sensor resulted from a loose ground (causing BSD communication faults), is not covered

under N63TU1 Class Settlement.

If the engine malfunction warning is illuminated and lean mixture faults are stored in the DME:

1. Double check all basic induction system connections, ensure no leaks are present.

2. Adaptation Procedure: Disconnect the tank ventilation valve (purge valve) electrical connector and allow

the engine to idle for 15 minutes. This procedure will allow the DME to readapt. After 15 minutes of idling

reconnect the tank ventilation valve (purge valve) electrical connector and clear the fault memory. Test

drive the vehicle to ensure all faults do not reoccur.

Workshop Cleanliness:

Always ensure the high-pressure fuel system parts are properly stored in a clean location. Use caps or bags to

keep contamination from occurring. It is good practice to immediately cap the high-pressure pumps and store

them in the upright position so that the plunger does not dry out. The appropriate caps can be found in the

N63TU1 Valve Seal Replacement Tool Kit P/N 83 30 2 450 434.
