Hi All

My son's 2011 Punto Evo Sporting 1.4 Multiair Turbo has developed a bunch of dashboard errors recently and we're getting nowhere fasy in resolving them.

It's always had an intermittent start/stop error from when we bought it 3 years ago, but after replacing the brake discs and pads on all four corners, we are seeing a raft of new errors, as follows:

ASR disconnected
ESP not available
Hill Holder not available
Check power steering

every now and then a check engine light/error pops up.


Fault codes from my multiecuscan laptop are:

Engine:
P181D-38 - gear lever position sensor (plausibility)
P1524-79 - Spark-plug anti-fouling function

ABS:
C0051-86 - Steering angle sensor (NGE)

Electric steering:
C1002-17 - Steering column motor torque position sensors

Dashboard (Instrument panel Marelli MY09):
U0019-87 - CAN line

So far we've replaced the battery for a new one and replaced the brake light switch (odd I know but I read somewhere, possibly on here, that a dodgy brake light switch can cause all kinds of issues with the affected systems)

The car drives fine with no strange steering behaviour, pulls cleanly and idles fine. when the hill holder error comes up that doesnt work on the car.

if I clear the errors, they may go away for 2 or 3 power cycles but will come back at some point.

We cant keep throwing cash at it blindly, so a couple of questions:

1) Anyone had similar or same symptoms and what did you do to resolve them?
2) Is there a trusted specialist folk would recommend in the NW Surrey/N Hants/Berkshire area (We're in Camberley)?

Thanks in advance for any pointers.

Did you scan the ABS system with multi scan, several of those errors point to an abs sensor fault, which could have a knock on problem with the steering errors and gear plausibility if the wheels are showing the computers they are turning at different speeds

I did check whether the wheel speed sensors all registered movement with multi ecu scan but i can’t say definitively that all four read exactly the same speed. the car is only here at the weekends so i’ll see if i can do a more detailed check next weekend..

if it is a wheel speed sensor, are they replaceable or is it a case of having to by a whole hub?

cheers

Sorry for late reply, but to help with anyone else in a similar position - the source of all the issues was faulty steering sensors which needed the upper steering column replacing. I found a company that did refurbishments on an exchange basis and I think it cost just over £220 for the parts, and an afternoon/evening taking the dashboard to pieces to replace it myself.
