Morning all,

my vRS (mark 1) has had problems in the last week, diagnostics shows code: P2138 - THROTTLE PEDAL SENSOR

A garage told me that they tried a new accelerator pedal and that this would resolve issue but did not. Their next attempt

was to extend the wiring loom behind the pedal, however this ‘fix’ was short lived, 1 hour later the engine cut out.

EPC and Engine Management Light came on

Car would not rev above 2000rpm

Car started shuddering

Then Traction Control light also appeared just prior to engine cutting out

I was very lucky it cut out on a quiet street and not on a busy road.

AA came out and the P2138 code listed above was showing again. He investigated the wiring behind the pedal and

checked the switch, cleared the code and got me to drive the 1 mile journey home, this was OK. A few more tests

and it appeared that the error had cleared and was not returning immediately. Next morning, went to drive to work, EPC on,

Car shuddering like hell, turned around and parked up on drive in case it cut out again.

I am keen for advice on the above and I am trying to figure out if I should go to a dealer workshop this time, been let down badly by garage in last week.

I have searched forums for EPC light and the error code, however symptoms all seem to be slightly different, thanks in advance for help

Hi,

I would agree with what you are thinking and let a main dealer look at this one as the fault code you have got has been obtained from a generic code reader. Dealer diagnostic or VCDS would give better information in solving this fault.Good Luck

Hi there, I've experienced very similar symptoms in my Roomster. I wondered if / how you resolved the issues? We've been led a merry dance by our local official dealer / repair garage telling us we need to change the wiring loom!!!
