UK-POLOS.NET - THE VW Polo Forum

Hi guys, need some help with my the car info follows:-

Polo 1.4 16V 75bhp
02 reg
petrol
67k on the clock

work taken so far to solve problems ( following diagnosis results )
I have recently had

In Dec 2013 had cambelt and water pump changed at 64k
Misfiring = changed all the coil pack
all new spark plugs
shown faulty EGR valve - Changed that to (brand new one )
Gave the car full service
Oil sensor changed
all new filters, oil changes etc
throttle body taken off and cleaned

done this about 1 month back
drove fine until a week back

recently i have been getting the following problems
1. engine cutting out when at a junction or whilst idling. starts straight away when it does cut out
2. rough idle ( like if the car is going to stall)
3. Sometimes whilst driving rev meter will jump up and down. loss of power then suddenly power will return, sometimes rev meter will stop working and oil light will blink red with rev meter not working. have to pull up to the side and restart to get the rev meter working again
4. car feels loss of power

TODAY I FINALLY GOT A DIAGNOSIS DONE below is the following results. Can you guys help me what to change or do on the following faults, many thanks

Could be a bad earth strap. This seems to be quite common in 9ns about this age now. It causes all kinda of issues like this

The stupid "bank 2 camshaft B exhaust" issue can be forgotten as unless you have fitted a V engine there is no bank 2! There should be a software update to sort that , my wife's Polo 2003MY BBY does that mainly in cold weather - and dealer knows nothing about updates, though there is some thing about that on the Skoda forum.

Barometric sensor is the MAP sensor, though as said, could be a wiring issue, though so far in 11.5 years and 100K miles I have not experienced any wiring issues.

This is the most common fault so far ( pic below)

As I'm driving the rev meter will bounce up and down 2-4 times (judders) power loss whiles its doing this then rev meter will stop working and the oil light will blink until I restart the car. The management light will stay on then go off after a day or 2.
as you can see the pic below. This problems I was having for about 3 weeks



I've now purchased a Engine Speed Sensor
Map Sensor for the previous faults on the diagnosis pic in previous

I've got a brandnew crank sensor, someone told me the rev meter cutting out is a Crank sensor fault, After these parts I have changed all parts

Next will be electrical if this does not sort it out

Not an answer to any of your problems, but, the MIL light will come on when there is a fault condition, if and when that fault condition goes away, the MIL light will stay on for a few engine starts - which is what you are seeing, what I've said just explains it!
