Hi all

I'm new here and have been trying to find "normal" or good sensor results for a live data scan. I have an Autel 519.

Despite much searching here and elsewhere I cannot find a list of "good" comprehensive data numbers. There is one post here (I can see) from Shiggys and Gasman, which mentions the main ones - and thanks!

I have a 2010 SE TD4 Auto.
In the past months I've been teaching myself to work on my car, after retiring, and not having much experience with cars, have had much help from this forum and YT videos - which has been fantastic!

Briefly:
Car was running rough but fixed by replacing split intercooler hose where it meets the throttle body which I also removed cleaned.

I've replaced:

Crankshaft sensor
Camshaft sensor
Final drive fluid
Haldex fluid
Engine oil
Fuel Filter (genuine part here)



The car has been running well, increased power, smoother acceleration. There is some slight variation in rpm at start up.

However, the other morning following start up a large plume of white smoke appeared (from the tailpipe) and then increased after gentle revving. It took quite a while to cease. I'm wondering if there may be an EGR valve issue?

I'm am desperately seeking input on the values from my live data scan and would be very grateful if someone could confirm they're OK and/or if any are suspect and possibly why - if known. If anyone has a link to "normal values for this Freelander that would be great too.

Apologies for the big list but I didn't want to leave anything out.

Results done after engine running at idle to normal temperature:

DTC_CNT 0
LOAD_PCT(%) 24.3
ECT(celsius) 77
MAP (kPa) 105
RPM 796
VSS (km/h) 0
IAT (celsius) 32
MAF (g/s) 13.77
TP (%) 83.1
02SLOC B1S1 ---B2S---
OBDSUP EOBD
RUNTM 1783
FRP (kPa) 25390
LAMBDA11 0.176
EGR_PCT(%) 0.0
EGR_ERR(%) 52.3
WARM_UPS 1
BARO(kPa) 101
VPWR(V) 14.261
TP_R(%) 0.0
AAT(celsius) 22
APP_D(%) 8.2
APP_E(%) 7.5
TAC_PCT(%) 100

Again, sorry for the exhaustive list!!

Many thanks to any and all who could alert me to problem numbers and perhaps how they look overall.

Cheers

Have you cleared out the old OBD Error Codes and read any new ones?

The FL2 is well self-monitored and should throw up errors to explain your rough running.

Intake (pipe)/ Turbo / EGR problems are quite common but hard to spot physical damage. FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)

Hi IanMetro

Thanks for your reply

The scanner has never shown any codes, even when there was a split in the intercooler throttle body hose, but I "cleared" them when prompted to do so.

Just wondering what is the intake hose you mention?

After watching some more videos, Beavis Pits/ Frenchies amongst others on Youtube wondered if perhaps the PCV valve (large housing) might be a cause? People seem to replace the whole unit even though I've seen just the main pressure valve and cap available. Though its a big job getting at it!

Many thanks

I meant the intake airpath and sensors.

Do you think that the white smoke is caused by misfuelling on start-up, and as its only occasional is it a loose/damaged sensor or injector or the wiring.

Its hard to give advice if no codes, I hope some one will step forward with correct readings or clue.

Hi

Thanks again.

I've no idea about the cause. But it is a start-up issue; though it's difficult to assess once you're driving - might get someone to follow me!

I'm guessing you mean the MAF & MAP sensors?
What other ones could I check?

Thanks for the link to further info too

Cheers

Hi Craigos,

For continuity it would have been better to have added to your thread that started 5th Feb ‘25.

As you will remember I responded to you posts……very surprised to read that your Autel 519 reader didn’t pick up any fault codes, even with the turbo boost hose being split……..it should have done…..!!!
Without a decent code reader diagnosis is difficult…….a bit of ‘hit & miss’ which can be costly…..

This afternoon I connected my AP 200 & did a live-data check….to compare with your readings….
Bearing in mind my FL2 is running perfectly at the moment thé main difference in readings are :
MAF 6g/s against 13.37
FRP…fuel rail pressure..44390kpa against 25390….both at 796rpm !
EGR PCT 19% against 0%
EGR-ERR 0% against 52%
Rest of readings are either irrelevant or similar….

What to glean from these readings….? Assuming readers are accurate…….
Your fuel pressure is lower but ok I would say
MAF is saying more air is flowing through intake…..could be lots of reasons
EGR ….my engine is receiving some recycled exhaust 19% as demanded (ERR-0) yours valve closed. ….

If your car is running ok just a problem of smoke on cold start-up.(but how cold in Ozz now ? ) it seems like heater plugs………..I believe they are difficult to access to check…..
If the smoke clears quickly & it’s not too bad I’d be tempted to leave it until winter or it gets worse…. FL2 SD4 HSE Lux Auto MY 2012— current
D2 TD5 HSE Man MY 1999 470kmls….gone 2014 ….lovely engine..chassis rotten
D1 300TDI Man MY 1996 56kmls….gone 1999…D2 much better
Wife’s FL1 1.8P MY 2001 32kmls …gone 2007…has Mini since.

Hi OxenPete

Thank you so much for taking the time to provide this comparative info. I'll follow your thread advice next time.

A friend with a PC updated the Autel 519 - which, despite him being a techie, was very difficult to find/complete.

As you say, "what to glean" ! I'll investigate the EGR but don't know anything about replacement/cleaning. I was intending to put in a blanking plate - as so many knowledgeable folk seem to do - and wonder of course what that would do to the readings.

The car is running very well, good power/acceleration/ ignition starts and stop immediately.
However I do smell some fumes. The smoke seems to have stopped.

The comparative test results are a worry though.

I did see a post from Gasman where his FRP was the same as mine - 25390
I removed and cleaned the MAF - but it doesn't seem to function like a gate/valve - so not sure if replacing that would help. Also wonder what role the PCV valve plays in this? The sensor could be malfunctioning to. I'll try to find - I guess 2 sensors that govern this.

Again many thanks, your stats have given me some direction.

Cheers

Again, what to glean!

Hi Craigos,

Further to yesterday’s post……
The first thing I would do is to do a scan & live-data run with either à ‘known to be accurate’ scanner or buy a new one……from experience if the reader is quite old it shouldn’t be trusted. I bought à Lynx Diagnostic kit when my FL2 was à year old….it connected to my HP laptop. I used it to reset the Service/DPF lights & ran a diagnostic check everytime…..in 11 years I never had a fault code…! I thought “what a fantastic motor”. I never had a problem with the car until last year…….except a stuttering when ambient temperature was above 20degC…….this got very bad so I tried to connect Lynx but it wouldn’t connect.
Having read good reports on this forum I purchased an Autel AP200…..dongle..not expensive. On connecting I had 19 DTCs…..nearly all historic…from years ago.
As mentioned in my posts thé AP200 first gave codes indicating discrepancy between MAF ( next to air filt) & MAP (above throttle valve). Changed both because they were easy & not too expensive…..made thé engine run worse…..after scan said air intake temp was -39deg ….faulty new OE MAF…..annoying.
After finding a tiny split in T/C hose & replacing it thé AP200 made checking the system on live-data easy & since car has been running great……..good diagnostic outcome.

Regarding fuel rail pressure…..MAF has nothing to do with it, it just gauges how much air is being drawn in. Yes thé PCV regulates pressure by varying the amount of fuel returned to tank.
Really I think you need to double-check the scanned readings before getting more involved……especially if as you say thé car is running ok………my view anyway…..
Good luck, Pete FL2 SD4 HSE Lux Auto MY 2012— current

Hi Pete

Thanks again for your info/feedback.

I needed to fit new bolts to the throttle body yesterday and so took the opportunity to flip the cap off the PCV and clean. Refitting the air intake setup and tightening everything.

Then went on freeway run for 15 mins and did another live scan once home.

Interestingly the MAF had dropped to a healthier (?) 9.02 gs and the EGR _PCT went to 20.0 with EGR_ERR oscillating between 0.0 and 1.6

Did another live scan at idle a few minutes later and the EGR figures went back to the EGR _PCT 0.0 and EGR_ERR 50.8, then back to 15.0 and 0.0 respectively. So I can only guess the EGR valve/cooler is on its way out?

Cheers
Craig.

Hi Craig,

As I wrote on my last paragraph above……is the car running ok….? That’s the main thing…..
If it’s running ok I wouldn’t go chasing problems…….
If there is a problem with the EGR valve then you should have some fault codes….like : P0406 or any P040 code………..assuming your scanner is working correctly…….
I know access to to EGR valve is very difficult……Jules did a very good post with pictures illustrating this,
so it’s a pig of a job to do……..only to be done if you have to……
So I say, if the car is running ok, leave well alone. If it’s not running ok you should see some DTCs.
