To each BMW enthusiast, we offer Online diagnostics for N43\/N53 engines!<\/p>\n

You are making screenshots using INPA<\/a> and sending to us<\/p>\n

We inspect all information and send back initial report<\/p>\n

If necessary further inspection will be requested<\/p>\n

Round 2 we inspect received information and give recommendations<\/p>\n

We provide assistance until all the problems are soloved<\/p>\n

What does it mean?<\/strong><\/p>\n

We will evaluate live data of INPA, sent to us by you, if necessary \u2013 will give recommendations for deeper research, if it would be required.<\/p>\n

What do you have to do?<\/strong><\/p>\n

Prepare the screenshots of the required menus from INPA and send them to us together with a description of the problem.<\/p>\n

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.<\/p>\n

We will help your car run smoothly again.<\/p>\n

Following systems will be checked (initial report)<\/p>\n

1. Basic data<\/strong><\/p>\n

Air consumption (air mass meter data)
\nThe temperature of the engine, coolant, oil, plausibility of these data
\nThe temperature of the exhaust system
\nHPFP and LPFP pressures<\/p>\n

2. Lambda probes<\/strong><\/p>\n

Chemical activity
\nHeating parameters
\nWide-band probes: proper Lambda readings
\nControl probes: the ability of voltage generation<\/p>\n

3. NOx sensor<\/strong><\/p>\n

Proper data sending and status
\nOffset value
\nWide-band and narrow-band Lambda data<\/p>\n

4. NOx converter<\/strong><\/p>\n

Status: normal or damaged (from live data)
\nAmount of poisoning<\/p>\n

5. Fuel mixture<\/strong><\/p>\n

Offset type adaptations: amount, the deviation between banks
\nMultiplicative type adaptations: amount, the deviation between banks
\nAdditional adaptations for a cold engine
\nLambda values and readings of Control probes (plausibility)<\/p>\n

6. Injectors (data for each injector)<\/strong><\/p>\n

Actual parameters: offset and multiplicative data
\nFlow rate tests for low and high loads
\nFlow rate tests for the cold engine
\nMechanical efficiency tests for Homogeneous injection (idle)
\nMechanical efficiency tests for Stratified charge injection (idle)
\nLearnbits: status of completed\/uncompleted adaptations<\/p>\n

7. Analysis of error messages<\/strong><\/p>\n

Status (active\/passive)
\nImportance and relationship with live data
\nDetermination of damaged component (errors + live data)<\/p>\n

Based on initial information, additional systems (if necessary) will be tested:<\/strong><\/p>\n

1. Check-up of fuel system: jittering of pressures, leakage, fuel distribution in the fuel tank;
\n2. Test of VANOS: offset adaptations, confirmed position, jittering;
\n3. Lambda probes: tolerance of parameters, current leakage;
\n4. EGR valve;
\n5. Crankcase valve;
\n6. Ignition system: misfire counters (ELM327 adapter required);
\n7. Generator; IBS; power management;
\n8. DISA valves;
\n9. Electric fan;
\n10. Engine cooling flaps;
\n11. Electric water pump;
\n12. Thermostat with electric management;
\n13. Oil pressure management;
\n14. Throttle and accelerator pedal; etc.<\/p>\n
