Engine & Electrical Fault Codes Guidance

[skoolz]

My Car Background....

funny coz I seem to have a similar problem on my SEAT ALTEA 07 1.9TDi. First about a month ago the interior light fuse went 7.5 brown one and I replaced that a few weeks ago. Then it went about a day or 2 after. replaced it and that wnet again. So I replaced it with a 15 amp fuse. Then the Inition lights fuse went a few days after and the cr would not start. I replaced that with a like for like 10 amp and car started but now the Drivers airbag light stays permanantly on. The start fuse went again the next day. Replaced that with a 15 amp but I think i have a short somewhere around the ignition and steering as the first time the start fuse, I heard the fuse go as I started the attempted to start the car. Also when the interior light fuse went for the second time, it happened whilst i was driving. The interior light was set to the permanently on position but the lights weren't on and whilst I was turning the steering wheel it came on briefly then it went of and when I checked the fuse had gone. Also importantly......... before fuses started going...a couple of times, I had instances where the car remained on after parking, switching off the ignition and pulling out the key. It would only switch off when I turned the steering wheel.

I know I have a problem but was hoping to get some experienced diagnosis/knowledge as what the issue may be, info from others that may have experienced similar, what was to resolution and outcome etc? Please Help? Will a VAGCOM be able to indicate what the issues are? Will I need a new ignition and probably coding....what are the costs of that?

I'm worried..

No help was received regarding the above post, now the engine emission control system light has come on so decided to purchase myself a VCDS 11.11 diagnostic kit and ran a diagnostic which returned the following errors...bearing in mind that i took my car earlier this year to the dealers, with my above issue and £50 after they say the diagnostic returned nothing:

I'm sure a lot of our Forum users including myself could really benefit from any assistance in how to go about resolving these faults without braking the bank, myself included.

Any help will be most appreciated guys

First thing to do is save a copy which you probably have to post it here!.
Then go into each module and clear fault codes. Run check on fault codes again see if any reappear. If not then go for a drive and rubn fault search again.
Quite a few codes are one offs and nothibg to worry about - note quite a few of the faults which may not be related occurred at the same milage.
( i find doing a general fault clear doesn't work anymore and you have to go into each control module)

So It's now been two years since I started experiencing electrical faults with my SEAT ALTEA TDi 1.9 07. Started off with the interior lights 7.5amp fuse blowing so I made do without them. Then after months the car started blowing the dash/ignition power 10amp fuse which would completely cut off the car. This would happen so intermittently but seemed o be always linked to a moment when driver was maneuvering the steering. Replacing the fuse and continuing sufficed for while. I made do with this for time and finally a point came when that happened and a replacements fuses where blown the instant i turned the steering wheel leaving me stranded. I had to be towed home by the AA. I made inquiries with various experienced electricians but none had heard of my issue and quoted me 30-40 and hour labour charge to diagnose it but couldn't say how long so that could go one forever. As we have two cars in our household and I don't use mine to commute to work, I made it a point to find the fault myself and rectify it. I removed the steering housing and looked around ignition controls for any loose wires etc, nothing. Finally today I removed the dash bottom housing and inspected along the steering column and noticed the Thick cable trunking with all the electrical cables from the engine/battery etc into the car, was wedged just above the pedals but cable tied close to the steering axle joint which is steel and square like. The rubber trunking section above the steering joint had snapped and upon snapping the cable tie and pushing the trunking away from the steering I noticed that where the rubber had snapped, there were about 3 exposed (bare) wires. Turns out due to the trunking being close (pretty much on) to the steering joint, every time maneuvering occurred, the friction scrapped the trunking first snapping the rubber trunking, then scrapping the wire plastic covering exposing the wires. Then every time the steering was maneuvered, contact occurred between the steel steering joint and one or more wires creating a short which blew the fuses etc. I have now pushed this away from the steering and covered the trunking again. Problems solved one and for all. Al error codes erased with VCDS and re-scanned. No Errors..... SWEET!!!!!! Pennies in my bank.

So please bear this in mind if you have steering related electrical short circuit issues.

Excellent post. You deserve some sort of prize for sorting this out and posting the solution on this forum.

 

[Nath.]

Good work. Just think how much it would have cost to keep taking it to the dealers and them throwing parts at it?
