Limp mode

[kim.barber]

Hi All,

Need help....

Polo 1.2 3 cylinder engine keeps dropping in to limp mode and shuts down one cylinder randomly....can be any cylinder depending what day it is.

Before you ask cylinder head has been off refitted new valves and compression all above 200 psi on each, changed camshaft and crankshaft sensor and spark plugs and checked most of wiring for damage or wear and tear.

We have changed ONE coil pack because which was showing as faulty and it still drops into limp mode randomly on different cylinders.

Please make the pain stop and come up with the answer ....currently all that is on dashboard is engine management light and not the epc

This sounds like an injector loom issue. Presume you have fully tested it?
