OT HELP !Skoda Fabia Engine Mgt Damsel in distress
Hi ,
Here's your chance to make the world a better place!!!
Query on behalf of a lady at work who lives in the country and needs a reliable car.
She has a 4 year old petrol Fabia about 60k miles, "it is red, average model" it has been OK and regularly serviced but has developed a
problem where engine suddenly dies - a general lack of power was the only symptom that warned of problems to come.
The problem has occured with increasing frequency. A trustworthy local garage checked fuel filters, fuel supply etc and could find no problem.
After last episode it went to the main dealer, with the help of the RAC, they checked obvious things and took car out for a drive and it repeated the
problem after about 35 miles (but at other times it can happen within 2 or 3 miles from home or even an hour down the motorway.
Dealer has spent a further 3 hours and cannot find the fault- obviously bill is starting to mount up.
Clearly this is a complex issue but help needed!!!
Questions
1 Is anyone on here familiar with this engine and its management or met this problem before?
2 Could it be solved by dropping in ecu from another similar vehicle that has had say a rear shunt but is otherwise OK?
3 Is there an after market modification that might help?
4 Failing a solution what's it worth - ?
morally car could not go to an unsuspecting member of the public, if traded in it would not get a good deal
and as a car full of decent bits, legal identity, decent body and MOT must have a value beyond scrap price.
I welcome your thoughts on this one, as usual thanks in anticipation for your time and expertise.

surely the main dealer could plug a comp in and read fault codes? Did nothing come up?

I once had a VW Scirroco which had a similar problem. Turned out to be a pre-filter in the petrol tank was clogged up. I'd change the air
filter, plugs, leads, fuel pump, fuel filter and dizzy before nearly killing the car!
Was due to rust / corrosion in the tank, new tank sorted it out lovely.
Oh and my BMW had similar problems last year! Engine management computer turned up nothing, it just died. Sometimes would go for 30 miles, sometimes
1 mile. That turned out to be a snapped cable to the fuel pump (located in the tank!!!). Because the pump was loose in the tank, sometimes the two
ends of the wire (inside the insulation) touched and it went, sometimes they moved apart and it stopped!
Took three garages to find that broken wire and £300 for a new fuel pump!

ive had a similar problem with a vw polo 1.6 which i traced to the main relay feeding the ecu and fuel pump which was becoming erratic after it got
warm and cutting the voltage to the fuel pump and ecu .it only showed up with the scanner plugged in giving live data and with the reference voltage
showing it dropped below 5volts as it cut out .the relay can be pulled apart and a dry joint was fixed.

not sure if this will help but we had this problem with a couple of cars one turned out to be the coil pack breaking down when hot
the other was a crank position sensor kept picking up dirt/debris and would kill the engine and put on management light

Hi ,
Thanks for the ideas - keep them coming please!
I have only ever seen car in the car park and now it is at the dealers - I don't know any of the precise details about the engine or about what
the dealers have looked at -but they must surely know their own cars and 3 hours seems a long time standing and scratching.

one of the biggest probs is the power hold relay open fuse box under dash and find a relay with eather 109 or 130 printed on strip it and you will
find a poor solded joint this is a very common fault and all vag cars if it was a coil you would get a fault code of p030...1..2...3....4
depending on the cylinder missfire and engine light on

There is a problem with the fabia engine bay looms. As the loom dip under the abs unit on the n/s rear of the engine bay it act's like a u bend
under your kitchen sink it just collects water. This in time rots the wires My problem was differant as the engine would't stop running but I
would slit the harness tape to let any water drain out. Please be careful with the loom as the wires can become brittle and will snap when touched. A
new engine bay loom is £2000 but Skoda will replace it if the car has a full dealer service history.

Any car 2001 will have an EOBD connector worth scanning the fault codes, even better if you know somebody with VAG-com on a laptop to read the freeze
frame data & live data.
Faults like this can also indicate a crank senor problem --- usually a bad connection.

An ex of mine's parents had a possibly similar issue, apparantly turned out to be contaminated fuel. Fully drained and re-primed fuel system and
it was fine afterwards.
beware, I've got yellow skin
