Getting to the end of the line with my 2010 Skoda Fabia 1.6. I've spent a small fortune on this car (my daily runner). 

 

My my wife had it today and said the engine management light came on. She thought it was an oil light, but that's another story! 

 

Car has done 86k miles, is serviced every 10k miles and doesn't sit in traffic on short run journeys. Plugged into VCDS and did a scan. The following error code came up.

Can anyone point ain't me in the general direction of what needs replaced before I drive to the harbour and put a brick on the accelerator!

 

Thanks in advance.

Read a little more about this and it could be Boost Pressure Sensor (combined MAP/IAT) apparently Bosch part BS0281002976.

 

Come to think of it, the car was running a little erratically in terms of engine idle. I thought it might be injectors, and was going to give it a course of Forte diesel conditioner.

 

So was your car serviced at a Skoda Dealers and did you allow them to carry out The Fix'.

So now you have new engine management and a flow device fitted?

 

If so then use the VW / Skoda 24 month Trust building measure guarantee to have a Skoda Approved Repairer resolve the issue at no cost to you.

Thank Offski, and yes Skoda carried out the emissions fix last year. Can I safely assume this is the cause?

 

I service the car myself and have access to VCDS - so have recorded the error and cleared it. 

You can not assume The Fix caused anything, but while you have the VW Guarantee be sure to let Skoda UK Customer Services know your vehicle has an issue then when or if another appears be sure to get your car in for them to diagnose and issue, replace parts etc.

Supply a courtesy car etc.

No point them giving you the Trust Building Measure and not taking advantage of it.    

Thanks Offski - appreciate you getting back to me. Like I said - I've cleared the error, which no doubt will re-appear at some point. I'll call Skoda if it comes back on and take it from there. It's just come back from Skoda after I successfully claimed on my warranty for rusty tailgate due to using foam pads on number-plate lights, instead of rubber gaskets.

 

These air pressure sensor faults are difficult to trace, could be the Bosch part, wiring, etc.

I’ve just had this issue do you have OBD fusion?

No, I have full licence VCDS from Ross-Tech. Engine light back on after 24 hours. Calling Skoda first thing to resolve.

Can you log the intake temp over a drive like this? 

Also where in Scotland are you?

I'm in Aberdeenshire. Regards intake temperature - breakdown of statistics, no idea, but I'm sure if I go into the guts of the VCDS, it'll be there somewhere.

 

It's booked in for Skoda to have a look on Friday. Word of warning if anyone is thinking of claiming against 24 month fix warranty. After speaking to Skoda reception - it's £108 for an hour diagnosis. If they are liable they they'll do the work free-of-charge. If it's a new fault unrelated to emission fix carried out last year, then I pick up the tab. It's a difficult one, as I'd use my local garage who charges a fraction of this and I trust completely, but there's obviously a cost at the end of the day. I need it resolved as it's my daily driver, but seriously thinking of getting rid of this car.

 

I've just got it through another MOT last month and has had the usual EGR, glow-plug issues which were expensive to fix. Never had as many issues with my old Audi V6 2.5TDI quattro, and that was on double the mileage. Trouble is, there's stricter checks at MOTs, plus the software VW has introduced needs to accurately report and regulate emissions, plus introduction of DPFs so there has to be a trade-off right?

 

Ah ok thought you might have been local and I could have datalogged it for you. 

 

Only reason I asked was that it was showing intake temp of -40

 

if you could datalog it and the temps all over then 100% it’s a map sensor. 

Appreciate it AMD, thank you. 

 

Will feed back what the issue is on Friday.

Car back and wallet £250 lighter. Fault traced to G42 air intake valve (broken wires). Skoda have a nasty habity of doing a vehicle health check too (which is just a way to scare you into parting with more cash). Advising about excessive handbrake travel, high-level brake light out, front discs scored, ball-joint cracking on bushes. Damn thing just passed it's MOT a month ago and this thing has been maintain religiously. Declined other work which would have pushed the bill to over £550.

 

The handbrake I know about. With rear drums - as the hubs wear, then ideally you need over-sized brake shoes which aren't available. I put new handbrake cables on it. The only real fix is new hubs. Front discs are scored, but are perfectly legal and will last a few more months. The high level brake like could have been Skoda themselves. It was in for a new tailgate last month under warranty. I'll check and replace if necessary. Lower arms - I'll check. Must have been good enough to pass MOT.

 

Thanks for replies to this.

Glad you got it sorted. 

my toledo has the minus 40c and p0113 coming up ,any idea?

Hi Wino and thanks for replying its a 1.6tdi 2013

77KW,CAY.

Look for an 8-way connector plug/socket pair somewhere around the alternator and A/C compressor area. Two of the wires coming off that are going to the intake air temperature sensor G42, along with two others going to the charge pressure sender G31 which are housed in the same physical package. Pins 5, 6, 7 and 8 of this 8-way go to the 4-way connector at the sensor, which  will be on some intake air ducting nearby.

 

On a contemporary Fabia, they are coloured brown, yellow, green and white between 8-way and sensor. Don't have wiring info for your Seat but it's the wire going to 2 (yellow in Fabia) of the sensor connector that is most likely to compromise the temperature info without also affecting the pressure reading if any wires are broken. On Fabia this yellow wire changes to a white one at pin 7 of the 8-way connector pair, on its way to the engine ECU. pin 30.

Experience suggests that a broken wire is more likely than a failed sensor, though either is possible. Check both sides of the 8 way connector pair as far as you can.
