S80 T6 2003 misfire

[RNOFD2509]

Hello all,

So I've had my S80 around 4 months, 3 of those trying to sort the transponder chip issue.... which I'm glad to to say, I did, without paying main dealer prices.

So I went to pickup the car, from my man who fixed it. After jump starting all was good, until...... I pulled away, the ABS came on. First problem....

I stop for a brew at my dads house on the way home.

On restart, still had ABS light on, then after about 100 metres down the road EML came on and car misfired.....

I guess most will say get the codes read.....but I do t want to spend a fortune on it. ( If any one is in the Ripon area help would be most appreciated)

But advice on where to start, or what could be the issues would be most helpful.

Car was stood for around 6 weeks after repair had taken place.

Should I check the plugs first?

Any comments or slating appreciated.......( get a match......)

Cheers Rich.

Having to have a car jump started points to a faulty building block of modern society...a weak battery or charging system or both.

Advice on where to start, you ask?
Make dead certain your battery is up to snuff. Have it charged it out of the car and tested..replaced if necessary then have the charging system checked out. That can be done right after the battery is reinstalled. This is a BIG and UNAVOIDABLE first step with today's cars.

Get a code reader of decent quality. At the rate you're going you'll have it paid for in no time at all.

Assuming the ABS code returns:
Inspect each wheel's lugs for tightness. Any wobbling can result in a code.
Inspect the ABS lead wires for damage.
Inspect the ABS notched wheels for presence and freedom of cracks.
All of this involves raising the wheel and removing it. Are you up to this?
I'm not certain how often ABS codes are "wheel specific".

A code reader can identify the cylinder involved in a misfire scenario and this information eases diagnosis.

EXAMPLE: P0300 is a general misfire code. P0301 through P0305 indicates cylinders 1 through 5 respectively.

Should, say, you get a P0302 code you can easily swap the coil between any other cylinder (select #5 for this example) and that of cylinder #2. If the next misfire code you get is P0305 you can conclude it was the coil as the problem traveled with the relocated coil to cylinder #5.

You always clear codes and make a note of how long it takes for them to return.
You clear codes before you do the example operation above so you're starting with a clean slate.

If you do not buy a code reader you're damning yourself to a life of paying for this simple service on top of any repairs you cannot perform yourself.

If you cannot grasp what I'm saying you're already damned. Happy Christmas, Kira
