Like I said on page 2 I had one in with this exact fault and a new dephaser fixed it. CLIP can confirm it to so I don't get why, if there is a problem, it isn't changeable under warranty... I guess they're treating it as a wearable part so not covered.

It is Jonny so doesn't have a relay controlling it especially not from the UCH. It has a dedicated feed from the battery and the rest is controlled/managed by the ABS module.
The relays you speak of on the back of the UCH switch the front fog lights, int wipers, etc
Still sounds high to me to unless you were giving it beans.
I'm not saying its timing but I'd want to see the live data to see what the MAP, H02 and CTS were doing.
What you really need to do is get the car looked at properly buddy as there's deffo a problem here aswell as a possible timing issue. We've had a spate of coolant temp sensors recently and this will drag the MPG right down to but they're cheap and simple fixes.
Timing is pretty easy to confirm...
Technically they're bad but really there's no right or wrong with them... they're essentially a carbon copy key with a duplicate S3 from your original.
From a diagnostic point of view though they are wrong as the car cannot distinguish between which key is being used at ay one time so it makes...
It is possible that the anti-tamper mode has been activated but it normally takes a lot more than an EODBII dongle to trigger this. Open the bonet > passenger side inner wing area > big black plastic box that isn't the air filter... open it > Inside you will find x3 blade fuses; 5A, 15A, 30A >...
I agree with Fred on this one and also build them in to my costings. They're on for around 5yrs and like all seals they have a finite lifespan. Just had a 182 in from Leicester that needed the dephaser following a "recent" belt change (Which allowed me to get some pictures of why the "TipEx"...
Probably going to be the switch at the end of the day but for what it's worth, I'd stick an oil pressure tester in to actually measure it to confirm/deny it being to spec.
I say this because whilst the oil pressure switches are fairly common at age and the pumps aren't. one common problem I've...
They had to provide it under block exemption rules chap and was part of the PDI check list. Technically its vehicle specific information and so should be provided with the documentation at the time of sale along with other bits of info such as the radio code though this was often not always...
I believe its the lobe that works the VVC camshaft position sensor pickup... a very common failing part on the later K4M which causes a nasty knocking and "injection fault" to appear on the display when faulty (Also DF137 iirc).

You will need an Oscillescope to be able to test the ignition drivers mate which is a pretty pricey piece of kit for the average DIYer.
Best off taking it to someone with one and is trained to use it properly in anger.
