You need the full codes for the other 2 as they will go to a further 2 digits.

You need a higher level scan tool to pinpoint problems

I thought the Nanocom Evolution would be the perfect tool for the job. It seemed to be the reader of choice for others on here. They're not cheap either

What readers are there which could give the full code?

I've also installed a second earth from the starter bolt to the negative terminal just in case but it made no difference. If the engine cools even slightly, the reduced engine performance and special programs off messages re-appear. Turning the engine off and waiting has no affect on the error messages. I have to wait for the car to decide when it wants to clear itself.

I'm getting really fed up with this car now. Its one problem after another which equates to me having to spend money!!!

This is the big issue, when the fun stops and the bills rise its decision time.

Most of our cars for the last 20 years have been swapped out while within factory warranty and the FL2 is the exception. I am trying to beat the breakdowns by over servicing it, example new battery before this Winter but once I get hit by a series of electrical problems it will crunch time.

Apart from depreciation running costs for the likes of service items / Tyres etc are currently cica £2 per day to include one large bill for a EGR valve.

We all need a good auto electrician locally but they are like Rocking Horse Crap to find now. FL2 MY10 TD4 GS traded in at 2 years

Hi Yorky Bob, you don't mind me asking how much was the bill for your EGR repair?

No change from £500 (with no VAT). Decided to pass it on to be done as caving down the back of the engine is a young mans sport. FL2 MY10 TD4 GS traded in at 2 years

A scanner will show information as far as it can. It's having the knowlege with what you do with that information.


Have a look at ScannerDanners intro to Scanners.

Whilst I have fitted a new earth lead between the starter and battery negative terminal, can anyone tell me what the minimum voltage would need to be in order for there to be a fault? My battery is only a year old but am aware it could have a fault on it. I don't want to replace the battery until I have measured the voltage without the engine running and compared that reading to the suggestions I get here.

Thanks in advance.

No idea of voltage but many places will do a free battery check even tyre companies like ATS. FL2 MY10 TD4 GS traded in at 2 years
