Technical Diagnostic code: P0106 MAP/BARO....

[waynem325]

Hi All

Having had to bite the bullet and accept that the VAGCOM cable I bought will not communicate with my ECU (Software and/or cable problem) I took my car in to my local garage and asked them to 'plug her up' to the diagnostic to see what is wrong?

As the title says it came back with

'P0106 MAP/BARO CIRCUTT RANGE/PERFORMANCE'

For those that don't know I recently purchased the car and was a little concerned when driving it home (250 miles away) that there was very little (almost none!) accelaration, and when hitting any kind of incline, speed would drop off rapidly. (Checked MAF and replaced broken air intake hose to no avail)

After researching this forum and bugging a few people (Thanks ) i discovered that the Engine Management LED had been removed :tosser: and therefore deduced that the law of averages suggests - if there was an LED in place it would most definitely be lit, hence why I bought a cable and eventually ended up at the garage.

So armed with this information I shall now approach the 'nice' chap I bought the car from, who incidentally operates as a trader from home (250 miles away), and see what he has to say?
I really can't be assed with the hassle this may lead to (I am assuming anyone removing a soldered EM LED to avoid repair costs isn't going to be reasonable) so wondered if anyone knows exactly what this code is telling me to replace and where I should start?
I realise the MAP sensor is the obvious one, and have so far found them available online for £40, but if that doesn't resolve the problem what next? I don't want to go 'gung-ho' and replace things which could lead to £££'s (especially when I have a valid claim for the seller to put it right)

If its a relatively cheap fix, then I will do it myself, however I will still have the problem of at least 1 missing LED which will need to be replaced. (Worth replacing the whole speedo cluster???)

Any info, as always, would be great

Thanks

Hello again mate,

IIRC one of the suggestions in your original thread was the MAP sensor, they are a very common failure on the 1.3 multijet. A faulty MAP would also illuminate the EML and put the car into "limp" mode resulting in severely restricted power. You could first try removing the sensor and checking that the small hole is not blocked with soot, however in my experience, a new sensor is normally the only way to go, try www.shop4parts.co.uk and use your FF discount.

Replacing the sensor is straight forward, although a bit fiddley. The MAP sensor is located at the back of the engine just behind the airbox. it has a single torx screw holding it on. There isnt much space between the sensor and the bulkhead, so its a bit tight to remove the screw. Simply pop off the wiring multi-plug, then undo the screw, and the MAP sensor will pull out.

As for the dash, was anything soldered in its place? like a resistor? as Im intreagued as to how he managed to remove the LED without bringing up the "LED failure" warning on the dash.

If you are good with soldering, its a fairly easy fix (assuming he hasnt done any more damage to the dash) you need a SMD, there is a guide on how to change your dash to blue SMD's in the guide section.

HOWEVER, it may be worth simply picking up a new dash on e-bay etc, as they often go for around £25. You need to make sure that the mileage on the NEW dash is LESS than the actual mileage on your car, as it can go forward but not back (easily).

Hope that helps,
Alan

Hi mate, it sounds like you have the same problem as me (see severe power loss post). The strange thing is- i don't have any EML on either. So maybe taking the light out is a common bodge or could it be that we both have a problem that isn't associated with the MAF sensor?? Alan has been helpful and reckons it might still be the MAF (might need referbing) even though i have bought a second hand one from the breakers and tried it (still get the same problem). If it helps at all, i'm going to referbish both MAF's (i have some electronics experts where i work who can replace any components) and try them. If it fixes the problem I'm happy to send you a working MAF sensor at the price i paid for it (£25).
Lets hope we can work together to find what's wrong with our normally Pokey Punto's!!

Alan (and Si)

Thanks for your replies. I did see them earlier but I've been having severe internet problems and so have finally opted to reply via phone - this could be fun??!

The MAP was definitely something you mentioned in a previous post, so before ordering a new one I cleaned up the old one a little while ago, which was quite thick with soot/carbon (pics to follow once laptop behaves) and to be honest I'm really not sure if there has been a difference? If there is then it is very tiny, though acceleration in first second and third feels a bit more 'pokey'? I'm reluctant to take it back to the garage to run a diagnostic test because if there's still a fault I'll need to order a MAP AND pay the garage for the diagnostic, again! And then check diagnostics again. I need to get my vagcom cable and software working soon otherwise this will cost a packet in no time.
I have a 20 mile drive to work in the morning so it should give me enough to tell of any change.

As for EML issue - is the LED warning an LED itself that should come on with the ignition lamp test? If so then that isn't working either! Could be a case of the second LED to go walkabout? I am pretty handy with surface mount LEDs but I have very little spare time to be messing around with that at the moment. I have looked on ebay but so far have found nothing.

Si - does your EML warning lamp come on with the ignition lamp test? It could be that someone has been removing your LEDs as well, although from what Alan has said so far, and from my own circuit board experience, if not removed properly then a lot of damage could have been caused. Fingers are crossed.
I'm unsure about my MAF - there was no change to the cars running when unplugged, but then if mines in limp mode there probably wouldn't be? Its a kind offer you've made, but hopefully one I won't have to rake you up on. I'm concentrating my efforts on MAP for now, but if I clear that obstacle and still have problems I will be in touch

Keep us posted, and when I can get an internet connection that is quicker than my phone I shall have a look at your thread.

I don't know as I could only peer through the crack in the 2 halves (Not wanting to take everything apart just yet) and where the shroud for the EML opened up above the circuit board, directly underneath, where an LED should have been there was nothing.

One thing that has just come to mind - when I collected my car from the garage, the mechanic mentioned that because the ECU measures the differences between electronic signals etc, he wondered if, when removing the EML LED and (if) nothing was soldered back in its place then the current that the ECU see's would be different to what it should be and thus creating a fault signal.

What say you?

 

[DaveMcT]

sounds plausible. Only a "new" dash would prove it.

 

[Si1969]

Hi - checked my EML and it does come on (Red) when starting the engine. It then goes straight out as it should. So it doesn't look like anyone has taken the LED out. I still have my MAF sensor problem or loss of power. Cleaned my original MAF sensor out the other day and need to fit it asap. but not confident it will cure the problem. We'll see. ...

 

[waynem325]

Very true but finding a new dash is proving troublesome. I may have to resort to soldering new LEDs myself

Si - have you had your car hooked up to a diagnostic machine yet? I dislike the idea of paying someone such a huge amount just to plug something in but at least it will point you in the right direction. I tried a VAGCOM cable myself but couldn't get the car talking to the laptop so I think I'll invest in an actual handheld machine - they seem relatively cheap on ebay, and certainly more cheaper than continued garage work.

Where in the country are you?

Hi mate,

Heres a set of clocks 23k miles £20... LINKY
Another set £40 - but doesn't say mileage so will need to ask LINKY
Another set 63k Miles - ONLY £10 - LINKY
Another set 23k miles - £20 - LINKY

I think Si has a JTD rather than MultiJet So it wont be fully OBDII compliant, meaning that fiat ECU Scan may be the best way to go for him.

As for your Multijet, its fully OBDII compliant so any OBDII scanner should be fine. Its a shame you cant get it to work on yours as it IS compatible with your multijet, and is a very useful tool, especially as its free.

Alan

 

[waynem325]

Alan, as always you are a star! Wouldn't the clocks have to be from a 1.3 Multijet and not petrol? Or are all dashes complete with ALL LEDs and only the relevant ones displayed per the car they are plugged in to?

EDIT:
Alan - you mentioned previously that the 'new' clocks I get should be lower than my current mileage (42k) - if higher what will happen?
On the basis of this I am assuming that if higher, the mileage would change to that of the new clocks...but wouldn't that also be the same if the mileage were lower?
ie; if changed with 63k miles my mileage would change to 63k, if changed with 23k my mileage would change to 23k?
Surely the mileage is stored within the car somewhere and upon plugging in the new clocks the actual mileage of the car will be displayed???

Will this work with my Punto?
Its from the same guys who sold me the VAGCOM cable, which I'm hoping they will allow me to return and send this out if I pay the difference. (Its cheaper than most on eBay and will give the sellers a reason to accept a return )

 

[Si1969]

Hi Buddy, No, i haven't had the car clagged up to a diagnostic. Like you say, I really begrudge paying a garage £45 just for them to plug a hand held computer in and reset the light. I'm 5 miles off of Jnc 11 on M27. Near Fareham.
Cheers,
Si

 

[waynem325]

Wow - small world mate. I'm 2 miles north of M27 J7.
I didn't realise Hampshire was the home to 2 of the slowest Punto's in the country?
At least if I can get a diagnostic thingumy jig then I guess we could try it on yours? (If it will be compatible?)

Watch this space

I took the car to SGM in Park gate (Fiat specialist dealer) this morning mate - had enough. I have 3 main probs -
1 - Air bag light
2 - Loss of power with MAF sensor connected
3 - Possible ABS problem (grinding when i brake along with sound of ABS motor running and ABS light on.

I have a feeling the loss of power could be assosiated with the wastegate on the turbo possibly seized open? Anyway, I've given up due to lack of time and the garage has got it now. I noticed that it said £75 for diagnostics!! Even BMW don't charge that much for a diagnostic check. So I'm waiting for a phone call today now. just hope it not one of those "are you sitting down sir" phone calls!!!
I'll let you know the outcome.
Cheers,
Si

 

[waynem325]

I never knew there was a Fiat specialist in Park Gate and I only live round the corner from there! Lol

I know how you feel - I've just about had enough of mine and getting close to contacting trading standards (bought mine about 5 or 6 weeks ago from a trader from home who is offering no help) or giving it to a garage and sending the trader the bill?!

I don't mind getting my hands dirty but I simply don't have the time right now, and for the next 3 to 4 months taking hours out of my schedule could be disastrous!

I'm going to prat around with my turbo and resolder/replace my speedo and if I get no results then consider my options.

I look forward to hearing what the garage have found with your car but I hope to God its a good phone call they give you. We know its going to be at least £75 - just hope its a simple fix..?

I commented on the other turbo diesel thread. If its coked up a Fiat dealer will screw you to the wall with a very big drill.

...If its coked up a Fiat dealer will screw you to the wall with a very big drill.

Hahaha...and they don't come much bigger than Fiats drill!

Any news Si..?
