while driving the glow plug light starts to flash and when i turn of the engine and start it again it stops put when i use the obd scanner a code remains: P0101, and says it´s the maf sensor. I changed the sensor and the air filter and checked the wiring and hoses around and up to the turbo put the light keeps on coming up and i´m out of ideas so i´m asking you kind people for help.

While I don't know the fault code(s) as diagnosis of an air ( MAF ? ) sensor fault is by my local independent VAG specialist I potentially have the same scenario.

 

The air ( MAF ) sensor has not yet been replaced but so far the car has absolutely no symptoms starting, idling or driving at any speed or situation.

 

An update with your current situation would be appreciated.

16485/P0101/000257 - Mass Air Flow Sensor (G70): Implausible Signal

 

Possible Symptoms

 

• Loss of Power
• Erratic Idle

 

Possible Causes

 

• Mass Air Flow Sensor (G70) faulty
• Air Leak(s) after Mass Air Flow Sensor (G70)
• Excessive restrictions in the Intake/Exhaust System
• Dirty air filter, clogged snow screen, clogged CAT
• Ground Spots corroded or Paint Residue
• Wiring and/or Connections from/to Mass Air Flow Sensor (G70) faulty

 

Possible Solutions

 

• Check Intake Air Filter
• Check Mass Air Flow Sensor (G70)
• Check Ground Spots
• Check Wiring and/or Connections from/to Mass Air Flow Sensor (G70)

My local garage did a diagnosis on my car this week, fault code came up as faulty throttle position sensor on the pedal. Refusing to believe that was at fault he checked the battery, he tells the battery is low.

The fault with the car, EPC light would come on along with the traction control light and the engine would go into limp mode. A new battery fitted and fault fixed, his reasoning the faults show up when a signal is sent to the sensors but not enough juice in the systems (battery) to bounce that signal back

I'll go along with that as the faults/lights have disappeared and car now drives great, it didn't get a great deal of use, 17k miles in 4 1/2 years the battery was most likely goosed as he said.

 

So moral of this ramble, get your battery checked first. He pointed straight to mine as a go to first he's seen it and tested a good few VAG cars

A garage worth sticking with. Everyone likes an accurate diagnosis, I wonder how many garages would have tried changing the throttle position sensor?

 

Failing batteries have always thrown up some really unusual faults on Skoda's. For the sake of £80 it's always worth trying the battery first.

Throttle position sensor alone priced up @£112.

 

Garage not without fault though but I forgive them, they ordered the wrong battery, as soon as I saw it I said wrong!  To be fair he would have picked it up before fitting, mine has stop/start so it's a hefty battery and a good few amps difference to the standard battery. For my inconvenience of waiting an hour for the correct battery to to be delivered he waived the diagnostic charge and any labour charges, battery was £141 though. Just thinking how much that could have been at a SEAT dealer, or would they have been still looking for the fault and still totting up the bill?

Also seems unusually common.  I never had a battery fail before our Rapid.

 

Ours went at only around 3 years old.  I always put this down to its life before our ownership (only did 3k in first 2 years after manufacture - sat ages unregistered, then spent an eternity unsold as a pre-reg, then owned privately for a really short period) - but maybe there's something more to it.  Cheap batteries maybe?

Yeah, I think Skoda went through a stage of skimping on their batteries, low Ah and CCA etc.

 

Modern cars are also much more demanding in terms of electrical consumption though too.
