I HAVE A 1.9 DCI MEGANE ON A 53 PLATE.BEEN HAVING PROBLEMS OFF ENGINE CUTTING OUT AT LOW REVS.
ITS BEEN ON A DIAGNOSTIC MACHINE WHICH HAS SHOWN THIS CODE.
0053.
ANY IDEAS WHAT THIS CODE REPRESENTS???

[Deano16v]

is that the fuel pump relay. i'm sure someone with autodata etc will confirm

[monkeymanonk]

do you mean fuel rail pressure sensor???

[onlydiesels]

i`m guessing that that is a `p` code (p0053) which according to my autodata says - heated oxygen sensor (ho2s) bank1 sensor 1 heater resistance.
probable cause- wiring,ho2s.. anyone??

[Deano16v]

it will be a P code yeah. and an oxygen sensor is a lambda, does the dci have a lambda?

ITS A DTC CODE. DIAGNOSTIS TROUBLE CODE AND ITS SOMETHING TO DO WITH THE FUEL SYSEM BUT I DONT KNOW WHAT.
