BMW INPA Engine Diagnostics EXPLAINED!

Diagnostics on Meeknet: www.meeknet.co.uk/E38/Diagnos...
INPA Interface: amzn.to/2Y5mBQg
Timm's store: www.amazon.co.uk/shop/timmsbm...
This video goes through how to use INPA to diagnose engine problems on the 6-Series, and in particular the N62 V8 engine, but these routines are suitable for all BMW engines right from the 3 cylinder to the V12. It's great fun, and you can't do much harm. In particular I go through Adaptations - and the dreaded error adaptations at limits.
We spend a bit of time explaining Adaptations and what the values mean. The strange terms such as Lambda Integrator, Total Air Consumption HLM, and the difference between Additive and Multiplicative Adaptations - all explained here.
OBDII to 19-pin adaptor: amzn.to/33CFRWN
INPA: amzn.to/33D2NoT
Further information can be found here: www.meeknet.co.uk/e38/diagnost...
Diagnostics can seem daunting to start with, so many pages of information and things to fiddle with. Most of us just check the error codes and leave it at that. Fortunately, there are three pages on INPA that gives us a window into the engine that is easy to understand.
Although this routine shows diagnostics on the M62 V8 engine, the INPA pages used here are useful for all BMW engines. These three pages, Analog 1, 2 and Smoothness gives an insight into the condition of the engine and any impending problems.
We also look at Adaptations and how the values can enable us to get the best performance and engine economy.

This was the best video explaining INPA, with extensive context for every function covered, pure gold. Most clips on yt are sub-par made my people who don't know what they are doing or are unable to explain properly. A series covering other aspects of BMW software coding/programming with this level of detail would be brilliant

I purchased the interface in your link because I get processing errors with my old one.

Great video Tim, wish I'd have had it last year when I was fixing up my 7series 745i (N62). It hadnt run since 2014 so 6 years in a garage with no servicing. It was missfiring on 4 of 8 cylinders. Eventually after playing with various odb readers I was able to figure out the MAF was very dead reading a value of 599 constantly. That got me closer, then their was a couple of huge vacuum leaks in a few pipes, the vacuum stabiliser things on top of the heads had huge holes in them too. I also had a few dead coils and decided to replace all of those and the sparks. Lots of oil around the sparks so a rocker cover gasket swap is on the cards for future. Ever done one? I hear vanos can be a pain to remove. I also had a dead valve that recirculates the gasses from the fuel tank, that one took ages to figure out and was putting the light on the dash which was really frustrating and only figured it out once I got to grips with inpa although I've never managed to get it to read errors in English. Once I had the engine running it was the turn of the other errors and mostly the airbags, although I was able to reset them.

[@TimmsBMWRepairsandInformation]

Great work Steve!

[@baitse7676]

I had a similar experience getting a 4.8is running after sitting for 1 year. It had a dead fuel injector, 4 bad coils, bad MAF and bad purge valve. Now it runs without any error codes. amazing!

From a Limey living in LA, your videos are a breath of fresh air, particularly as I am 2007 650i N62 owner! Can I suggest you make a video of a tour around the engine, showing each component and giving your explanation on function and possible issues.

Sorry to bring up an old video, I was watching trying to diagnose an intemittent 02 sensor code. It randomly, becoming more common infact pretty much when it warms up it starts to misfire and throws a 2C45 code. The code is for pre cat 02 sensor, I will replace it, but i was watching some live Inpa diagnostics and my air mass was varying from about 12 to 20 kg/h constantly. Is it worth replacing the MAF sensor as well ? or should i just give the wiring a going over

[@TimmsBMWRepairsandInformation]

O2 sensor warnings are an indication that the fuel/air mixture is wrong - not the sensor itself. If the MAF is showing a huge range of readings then yes, it should be replaced - OEM BMW only!

[@khesbej]

Hi Timm. Thanks for the great work with the videos. I am considering purchasing a 645 2004 coupe at a heavily discounted price. The car has not been driven properly for almost a year and seems also to not have been that well maintained. Went in for oil leak fixes just before being parked. Also has coolant lights on etc. Is it worth the gamble?

This was the first video that explained so much about INPA and what everything exactly means. Thank you very much for the easy explanatory. My N46B20 runs a bit rough sometimes. I replaced the MAF but INPA shows a Air Mass of 8.5 in idle. Is this normal? Because it should be around 22 and 25 right? Could something else be the problem besides the MAF

[@TimmsBMWRepairsandInformation]

Thanks! Yes 8.5 is much too low, check for a hole in the bellows between the MAF and the throttle body - if all good then it's time for a new MAF

[@jaydevhpatel]

Hi Tim, Great vid, very informative. Just to say I made a comment in your other INPA video about my slightly rough idle and I think my values on the page 'analog value 3' the O2-sensor Add Banks 1 & 2 are -1.70 and -2.30 which suggests a lean adaptation ? , unlike yours which are much closer to -0.3 & -0.5. Q. Do you think I'm looking at a MAF fault as I don't think it can be an air leak?, Thanks for your advice. J

[@TimmsBMWRepairsandInformation]

It could possibly be MAF - but your values show the mixture is too rich by a small amount - and that could be misfires - possibly causing the rough idle.

[@jaydevhpatel]

Thanks for the reply, OK yes. Couple of things before all of this, I did get the coil packs changed and the four vanos. So before I even get to look at the injectors, I think your suggestion of investigating the MAF is a more plausible option. Do you think cleaning the MAF is a good idea. Or a replacement is probably better? Thanks for all your help and videos. Best. J

[@carlossaez9389]

Hi timm, love your videos i wanted to ask you if you have had your engine idle speed set point adjusted, it's 750 in this video, mine is at 550, idles better a bit higher, read in forums that 550 is normal for N62 and 700 with ac on.

No change made, but with working air conditioning ON the revs should rise to around 700. This has been the case on all BMW'S since A/C was introduced

Bank 1 values are perfect, 67.80 / 126.20 respectively Both in the green! Yet, Bank 2 Output starts in the green (68.00, though adaptation input bank 2 is well low @ 67.90. So (B1 67.80 output = green / 126.20 input = green), and (B2 Output 68.00 = green / 67.90 input = red). Have you a suggestion why? All the CPS have been changed or new, solenoids are new.

Have you run into incredibly loose ignition coils? My n62 4.4 has some bosch and some NGKcoils. Some coils are nice and tight while others just seem to be staying in place just by the bottom portion that joins the sparkplug. It doesn't matter how hard I push, some need no effort to pull out. Could it be the spark plugs tubes not sealing?

[@TimmsBMWRepairsandInformation]

Yes, but on the M62 - the loose HT boots are caused by oil contamination on those. They should be tight - I only use Delphi coils and have never had any problems with them.

High pressure fuel sensor also shows -444.000 do you have any ideas what could be wrong? Thanks in advance

[@TimmsBMWRepairsandInformation]

Hello Dan, the fuel pressure has to remain high even when the engine is switched off - for many days. From your description it sounds as if the fuel pressure is leaking away which is why you can smell fuel. Pop the covers off and have a look around the fuel pipes.

It appears to be the same 3 as before. I believe each coil has a 12V +, neg and a trigger signal. If I have a trapped loom does this mean something is shorting to ground?

Yes, that is most likely loss of fuel pressure when the engine is off. It should maintain a pressure of around 2,5 Bar indefinitely. The pressure is maintained between the Fuel Pressure Regulator and the fuel pump which has a one-way valve built into it. Some owners fit a one-way valve in the fuel line because of the cost of pump replacement.

Hi Timm, I notice you get around 22 kg/hr on your MAF at idle. My X5 4.8is with N62 motor is getting about 29 kg/hr at idle, and INPA is saying that is out of range. That's with the AC running. I should try again without the AC running, but does that sound high to you?

I'm trying to get into INPA. It's really the only option if you're on some of the old Bosch Motronic 3.1 stuff. Like the early M50's and M60's without VANOS etc. Those ODB cables are no good for the old engines. You need a connector for the 20 pin plug in the engine bay, with serial plug in the other end. Then you need a laptop with an actual serial port and bloody windows xp. Serial ports stopped being on regular laptops around 2007.

The only ADS interface still around is the Tiny ADS, but it does work!

Anybody found a way to check the oil level using INPA?

[@ToXic9931]

hello. Does anybody know if the bmw e39 523i m52b25 has the narrowband or wideband pre-cat o2 sensors?

[@TimmsBMWRepairsandInformation]

They are narrowband, same as all E38's and E39's

[@ToXic9931]

@@TimmsBMWRepairsandInformation thank you, then i have the wrong o2 sensors in my car. because when i checked the voltages it was changing between 0v-4.7v

[@Rafa_guitars]

All adaptions in my car are reading 0 all the time even if I cause a vacuum leak. what could be the issue

[@TimmsBMWRepairsandInformation]

If the adaptations stay at zero then the Lambda sensors are either not up to temperature (takes around 5 minutes) or are not connected or have failed

[@Ali-uv3dz]

Vanos ?

[@povdrivekls8369]

can i clear the engine adaptations with inpa?

[@TimmsBMWRepairsandInformation]

Yes you can!

[@povdrivekls8369]

Does this work on a 2014 535d xdrive f10

[@TimmsBMWRepairsandInformation]

Never had a diesel but I would guess it will be similar!

[@steviem2224]

Gutted my 635d is a write off after water damage from flooding the other day need to buy another just don’t know which one thinking 645 or 650 they all seem quite high mileage 100000 plus which is little bit scary for a v8

[@TimmsBMWRepairsandInformation]

Get a 650i - More horsepower is always the winner!

[@Gemotogen]

Why do you have 4 power windows? Because you have a convertible?

[@TimmsBMWRepairsandInformation]

Yes, I was really surprised that the E63 didn't having dropping back windows - or was pillarless whereas the E31 has both. The E64 convertible is the same.

Hi Timm. Do you ever use ISTA D/ ISTA+ and what do you think about it?

[@TimmsBMWRepairsandInformation]

Hello my friend! ISTA and DIS just run so slowly on my old PC I just can't use them - and I find that INPA does all that I need to - and very little chance of breaking anything!

[@TheKeenMechanic]

@@TimmsBMWRepairsandInformation I like inpa but inpa doesn't have some of the features that ISTA+ has. I have a facelift E38 with a very rare Active cruise control that nobody can fix for many years. I started learning how to use ista+ and eventually I managed to re-calibrate the ACC unit. As far as I am aware you simply can't do something like that with inpa. Great video and very informative as usual.

[@peterpanda9324]

Hi Timm, trying to track down an intermittent rough idle on my e63 n52 engine, could you help me figure out what's happening? I've uploaded adaptations video, cheers. kzbin.info/www/bejne/ZqmVmYuAq62EitE

[@TimmsBMWRepairsandInformation]

The adaptations look OK, possibly affected by a misfire - so it is not a fuel/air problem, more likely plugs and coils.

[@peterpanda9324]

Timm's BMW Repairs and Information, Wow! Thanks for having a look 😊! I have done the usual suspects - coils, plugs and injectors. I’ll check out vanos solenoids and MAF then. Cheers 🍻
