197 EML and battery draining probs (techies look in please!)

[Matt Cup]

I've got a couple of issues with my mums 197 at the moment, the EML popped up on the dash last week, I took it to the local garage and they ran a diagnostic and gave us this report. The garage cleared this codes and the car seems to run fine.

Meanwhile whenever the car is left standing for more than a week the battery drains to practically nothing, we have replaced the battery twice to rectify this. I'm at a loss as to why it drains even the garage noticed that the battery was running down as they had left it a few days before looking at it. Could this have caused to the above issues or is it a separate problem?

Cheers

Matt.

DF080, open circuit?

Look into that, could be causing a power drain!

Edit: Maybe not. But read this from mick.

Thanks for the link mate, hope it's not down to incorrect timing... it's had the belts changed around 2 years ago.

 

[ThomasBrentnall]

No problem, I can't really comment on the timing as I'm not mechanical at all But yeah hopefully it won't.

Speak to mick though he seems pretty good with stuff like that!

Camshaft sensors on the k4m engine cause a battery drain but Iv never seen one fail on a f4r.

Get a new one on there.

Firstly, ignore DF080 (for now at least). The dephaser circuit will not work without the camshaft sensor input and priority should be given to DF119.

I've changed a few CPS on the 197 F4R which has fixed these BUT I've also had a couple that needed a dephaser also.

Ideally you need CLIP here to see what is actually occuring within the VVC and yes I am aware there are other bits of kit out there but I've yet to see a snap-on Solus give decent, reliable parameter data on this circuit. Then you need someone to confirm the wiring between the UPC, ECU & CPS but if you want to take a gamble replace the sensor... please buy a genuine unit though and not a GSF £27 cheapo as they never last.

Thanks for the reply Mick. Looks like I need to find someone local with a CLIP device, otherwise I'll be giving you a call sometime soon

The flat battery issue it's got too, could this be related or just a coincidence and a separate problem?

 

[MicKPM]

It could be yes as mentioned above, they do pull the battery down on the K4M unit when faulty.

Quick update, took the car out for a good drive today and the light/dash board display has stayed off. I will just have to see whether or not it stays off.
