Hi All FR TDI Woes

[blackie39]

Hi everyone

My Daughter recently purchased a white FR TDI 170 from a garage. All seemed reasonably ok
85000 miles 2010
full lease car history
mot 2 days old
tidy with nav & half red/black seats
we collected the car and on collection the nav sd card was faulty . No problem just get one & i will reimburse said the dealer

Got home to plug in the VAG. There was a few issues which cleared but one main one was air compressor too low. My friend suggested a regas & offered to do it at his garage.
The next day the coil light came on.
Out with the Vag again. Maf sensor signal low.
Then it went off
Then on again until the EML stayed on.
Meanwhile a regas showed all holding but no compressor.
I advised the dealer i was taking it to awesome for a full check & service

Faults found

Rear spring broken (MOT fail)
Rear tyre on wrong way round (MOT Fail)
Tracking out so tyres rubbing
Maf sensor fault (car still pulls like a train)
Aircon compressor broken
Aircon pressure switch faulty

So we take it back to the dealer who isnt happy

He has had it 2 weeks & to be fair he has repaired everything apart from the nav

New compressor & switch
New Maf sensor (receipts shown & i know its new as i put a mark on the old one)
New springs x 2

Anyway whilst i witter on we have collected the car & all was ok until we have restarted the car & the maf fault is back

The car still pulls like mad & its a new maf. I have been told it could even be a brake light switch ?

Is this a wifes tale or do i need to be looking elsewhere

Thanks for reading & hopefully someone can make my Daughter a happy bunny again

I think I'll get the meter out and measure the voltages in the loom

I had a similar fault on a 2005 Ibiza FR TDI and it did turn out to be the brake light switch! Not sure if its the same on the Leon though.

Have you had any luck with it?

Did they replace with a genuine maf or a cheap repo to save money if its the cheaper version I expect thats at fault!

Hi All

Thanks for the replies. OK so the plot thickens

when it came back from where we bought it from it was on its 3rd MAF.

It was ok for a few days then limp mode again. A few days later the DPF light came on.

I tried to do a regen with no success so we booked it in with Awesome.

The lads did the forced Regen & this cleared the MAF fault also. She drove home & it came on again.

Took it back 2 more faults . Throttle position sensor & Turbo actuator.

Both these have been repaired but the MAF light came on again. RUnning the diag Awesome said it was the MAF again as it was running around 500 & new one should be around 1000 on the VAG.

Anyway, Agreed to a 4th MAF to be fitted but after fitting Awesome kept it & lo & behold it came on again in the morning with THE NEW MAF. They found some corrosion around the MAF plug so have ordered this but im sure its something really simple thats being missed

My Daughter as you can imagine is well pissed off. This is the WORST VAG car we have ever owned & its really put her off keeping this car.

ANy other pointers would be greatly appreciated ( Ive already recommended a gallon of unleaded inside it)
