Seat Leon tdi, plethora of fault codes!!

[shiftyseamus]

Hmm, just bought myself a 2003 tdi 110 Leon and it seems to have 'issues'!!

When I got it I knew the central locking wasn't working and to be honest wasn't too bothered.

Not long after the car lost power so I did a scan, its come back with some scary results!!

The Supply voltages I'm assuming are coming from the alternator fault or a bad ground/cable break/poor connection

I'm gonna mr muscle the turbo to clean the vanes.

The traction light comes on on the dash after 5 minutes(abs sensor)

The alarm goes off if you don't put the key in the ignition directly after opening the door(drivers door lock?)

Any thoughts (perhaps a gallon of petrol and an insurance claim form may help!!???)

Its done 91k miles with full history

 

[matty85]

First thing I would do m8 is clear all codes then see what comes back a few of them codes can be caused by a low battery. It will be ok.

 

[shiftyseamus]

Cheers, I'll give it a go, just chucked a multimeter on the battery and its only 11.8 volts with the engine running.

If I have to spring for an Alternator then its not the end of the world.

 

[BigJase88]

Reset all codes and see what re-appears

Alternator load sensor fault is a broken cable below the battery tray! Common problem on all VAG cars

 

[Mark D]

Alternator is a big one for vag, go a lot and cause loads of false readings. Run a battery and alternator test no doubt find you need a new alternator and charge up the battery.
Clear all the codes and give it a good drive see what happens.

When my old fabia battery was almost shot it did all types of crazy things. Got dangerous so sooner is better.

 

[shiftyseamus]

Just cleared it all and went for a run..

Bit less of a list now, I'm a lot happier with that!!

Any thoughts on the above?

I've had a quick look at the wires and can't see any signs of breakage.

 

[Mark D]

Found this on a TDI forum: Bit more depth and to see what your looking for:

Having read Wingnut's Glow Plugs 101, I knew how to proceed with the glow plug fault but was stumped as to what the second code meant. So being a good little TDIclub member I did a thorough search and came up with little on how to fix the code. I do have to give credit to Whitedog for finding information on the fault on a Seat site and posting it up here. Since we don't already have anything on the topic, I figured I would get this out there. The code, by the way, does not display a CEL (in my case the glow plug fault did that) but gets stored nonetheless. My car seemed to store the code everyday - I cleared the code at night, commuted the next day and checked the codes when I got home with it displaying the 17911. I repeated this 3 times, all having the same results.

The problem: On the front side of the engine is a harness that runs from the alternator, voltage regulator, and A/C compressor (if so equipped) to the main harness underneath the battery box. Apparently, VW decided to make this harness ~1" shorter than it should be which becomes an issue at a four pin connector (2 pin in the case of no A/C) located on the starter.

There are five wires in the harness:
1) Large red power wire from the alternator. Goes to the fuse panel on the top of the battery.
2) Green and black wire from A/C compressor (actually for A/C compressor clutch). Goes through third pin on the 4 pin connector to ?
3) Brown and black wire from A/C compressor (actually for A/C compressor clutch). Goes through fourth pin on the 4 pin connector to ?
4) VERY small brown and red wire from the voltage regulator. Goes through the first pin on the 4 pin connector on its way to the ECM.
5) VERY small blue wire from the voltage regulator. Goes through the second pin on the 4 pin connector on its way to the ECM and Generator indicator light in the dash, as well as the warning chime.

On my car, #4 was completely disconnected; #5, and #3 were also well on their way (the sheathing had cracked and the wires were frayed).

My first step was to pull the harness from the car to see if I could salvage the connector. To do this the battery, battery box, air cleaner and engine cover came out to gain access to the various points of attachment. Once out, I noticed that all the damage to the wires was less than 1/4" from the connector making soldering somewhat difficult. I came up with 2 ways to fix the short, broken harness: 1) pull connector apart, lengthen wires, rebuild connector 2) remove connector, lengthen wires, permanently attach the harness. I decided to go with the latter option since I kinda mangled the connector trying to pull it apart (I don't think they are meant to be serviced) and also because I didn't think the connector was necessary.

So out came the soldering iron, wire strippers, heat shrink, 16ga wire, and wire loom. The whole process was pretty painless, that is if you don't count the couple of times I burned myself and the 10deg parking lot that I had to do the fix in . I buttoned everything back up and fired it up and took it for a spin, keeping my eye on the CEL to see if anything had been screwed up - nothing. When I got back I ran a VAGCOM to see if the 17911 was stored again and....success, no more implausible signal.

I look forward to see if this fixes my other problem of frequently blowing taillights, headlights and brake lights. My guess is that the completely disconnected wire was touching one of the other exposed wires in the connector...possibly the ground (?) for the A/C.

Anyway, I hope this helps shed some light on the 17911 fault code. Happy TDI'ing.

No its the alternator load sensor wire runs under battery tray! Theres are 2 cables for this and either can snap, both causing different issues!

The OP's issue is a broken wire which causes the car not to charge the battery at idle, if the OP gets someone to rev the car above 2,500rpm then the alternator will start charging the battery! I can bet my house on it!

Alternator is fine!!

 

[Mark D]

Yes further research agrees with that...see my newer post

Woo Hoo!!

Thats good news!!

I'm assuming its gonna be one of the 2 small wire thats broken?

Sounds an easy(and cheap) fix as well, cheers for that :thanks::thanks::thanks:

 

[BigJase88]

Yeah theres 2 symptoms dependant on whats broke

One is no battery light on instrument cluster when you put ignition on
The other doesnt charge the battery at idle, only starts charging above 2,500rpm iirc

Easy fix! Wires run over top of gearbox under battery tray, will be snapped

 

[shiftyseamus]

I'll have a looksie at them ASAP.

That leave this one..

Any thoughts on what this could be?

I'm assuming its the reason why the traction light comes on on the dash after about 10 mins of driving?

 

[shiftyseamus]

Just been doing some research and it seems this 01314 code can be linked to the MAF sensor and also cause ABS problems?

Is this possible???

 

[shiftyseamus]

Just for info..

Car is now sorted.

MAF didn't fix the ABS problem, but it did make it run a hell of a lot better!!

Brakes are fine now but it could have been one of 2 things that sorted it, both front ABS sensors were changed.

The alternator fault wasn't a broken wire, its just wasn't connected at the alternator!!

Its possible the alternator wire was affecting the abs??

Anyway, am now happy with the car.

Thanks to you all for your help, very much appreciated

Well thats a strange one! Have a garage at some point had it off an not connected it back up?

 

[shiftyseamus]

Who knows? The alternator doesn't look new, although it could have been 2nd hand one fitted?

I didn't do the work but my mate who did says that it just couldn't have fallen off and was either missed out deliberately or just not connected due to stupidity!!

Someone could have been playing with it trying to 'fix' another fault??

Spent a few £££ but its all good now(well I hope anyway!!)

 

[BigJase88]

Quite possibly!

Its like my work van has unplugged connectors going everywhere! Engine starts and stops! Who knows
