To each BMW enthusiast, we offer Online diagnostics
for N43/N53 engines!
How does ONLINE diagnostics works?
You are making screenshots using INPA and sending to us
We inspect all information and send back initial report
If necessary further inspection will be requested
Round 2 we inspect received information and give recommendations
We provide assistance until all the problems are soloved
What does it mean?
We will evaluate live data of INPA, sent to us by you, if necessary – will give recommendations for deeper research, if it would be required.
What do you have to do?
Prepare the screenshots of the required menus from INPA and send them to us together with a description of the problem.
(E81/E82/E88/E90/E91/E92/E93/E60/E61/E63/E64).
INPA MSD80 Loader 2.023 is necessary
We will send the report as soon as possible with comments regarding incorrect or suspicious values, the report will be supplemented with images with marked incorrect values. We will give also suggestions and recommendations for required tests if the defect could not be recognized from the data sent.
We will help your car run smoothly again.
Diagnostics include analyzing all engine systems before repair and the progress inspection after repair (one occasion). If a repeated examination is necessary (for example, injector installed turns out defective), the costs of each subsequent review are 30€. A reduced fee applies only to used injectors installed and only while the injectors are not available on the BMW dealer’s network. If the customer does not follow the instructions and/or uses other used/low-quality spare parts, which perform unsatisfactorily after installation, the repeated diagnostics fee is 50€ – standard price.
Following systems will be checked (initial report)
1. Basic data
- Air consumption (air mass meter data)
- The temperature of the engine, coolant, oil, plausibility of these data
- The temperature of the exhaust system
- HPFP and LPFP pressures
2. Lambda probes
- Chemical activity
- Heating parameters
- Wide-band probes: proper Lambda readings
- Control probes: the ability of voltage generation
3. NOx sensor
- Proper data sending and status
- Offset value
- Wide-band and narrow-band Lambda data
4. NOx converter
- Status: normal or damaged (from live data)
- Amount of poisoning
5. Fuel mixture
- Offset type adaptations: amount, the deviation between banks
- Multiplicative type adaptations: amount, the deviation between banks
- Additional adaptations for a cold engine
- Lambda values and readings of Control probes (plausibility)
6. Injectors (data for each injector)
- Actual parameters: offset and multiplicative data
- Flow rate tests for low and high loads
- Flow rate tests for the cold engine
- Mechanical efficiency tests for Homogeneous injection (idle)
- Mechanical efficiency tests for Stratified charge injection (idle)
- Learnbits: status of completed/uncompleted adaptations
7. Analysis of error messages
- Status (active/passive)
- Importance and relationship with live data
- Determination of damaged component (errors + live data)
Based on initial information, additional systems (if necessary) will be tested:
1. Check-up of fuel system: jittering of pressures, leakage, fuel distribution in the fuel tank;
2. Test of VANOS: offset adaptations, confirmed position, jittering;
3. Lambda probes: tolerance of parameters, current leakage;
4. EGR valve;
5. Crankcase valve;
6. Ignition system: misfire counters (ELM327 adapter required);
7. Generator; IBS; power management;
8. DISA valves;
9. Electric fan;
10. Engine cooling flaps;
11. Electric water pump;
12. Thermostat with electric management;
13. Oil pressure management;
14. Throttle and accelerator pedal; etc.
